I installed .net6 but i need to have installed .net5
So, I removed .net6 and I installed .net5.
Now, when I run 'dotnet build' command I have the error:
A fatal error occurred. The folder [/usr/lib/dotnet/dotnet6-6.0.108/host/fxr] does not exist
Do you have some idea to help me, please.
Thanks
.NET 5 has reached its End of Life. If you are using it, you are on your own; don't expect any fixes for security issues that discovered every few weeks.
Anyway, sounds like you are using Ubuntu 22.04.
If so, you are out of luck. There's no simple way to install or run .NET 5 there. .NET 5 needs OpenSSL 1.0 or 1.1. Ubuntu 22.04 only has OpenSSL 3.0. Even if you install and manage to run .NET 5, it wont work and you will get OpenSSL errors.
Your best course of action is to install an older version of Ubuntu, such as 20.04.
Your specific error in this case is quite unrelated to above, though. Your error is because you seem to have installed some packages from Ubuntu's package repository and some packages from Microsoft's package repository. See https://github.com/dotnet/core/issues/7699#issuecomment-1222470580 for details. In particular you want to follow the steps in "Mixed state scenario 2: Use PMC packages after installing native Jammy packages". But that's not needed on Ubuntu 20.04 or similar OS that you need to make .NET 5 work at all.
How to install GCC 4.8 on RHEL 7 in offline mode? (not registered with Redhat).
I searched for a solution but couldn't find a proper one.
There are two options that we can use
1) Create a local yum repository from DVD/ISO file - Google search will throw lot of links. One such thing is https://access.redhat.com/solutions/1355683
2) Another option is use the Centos repository. Centos is derived from RHEL and should be safe. You can set this as you repository. But, I will go for the first one
Not sure about GCC 4.8, but V6.3.1 is available via the Developer Toolset. See https://developers.redhat.com/products/developertoolset/updates/
I'm believe GCC 5.3 may still be accessible too.
There's a no-cost RHEL developer subscription to download here: https://developers.redhat.com/products/rhel/download/
HTH
I am trying to use the old version of 32 bit cygwin (1.7.22 - 1.7.32) which uses GCC 4.7.3 version.
Just found one (cygwin 1.7.25) but during the standard installation (running with setup-x86.exe) it shows the following errors:
The current ini file is from a newer version of setup.exe. If you have
any trouble installing, please download a fresh version from "cygwin
official page"
Is that old version not supported anymore and I can not chose right address from where it can download and install the needed packages?
Thanks,
Arsen
I can't find a good answer. Normally what you see in the installer is what you have access to.
When you load your setup-x86.exe, get to the packages (ignore the warning), and see if you can select the version of Cygwin you need (use the search box to narrow it down). On mine I can only get a few revisions and nothing as old as you need. That being said, I do have the latest installer and can't test this for you.
The most recent version of ScraperWiki depends on Poppler (or so the GitHub says). Unfortunately, it only specifies how to get it on macOS and Linux, not Windows.
A quick googling turned up nothing too promising. Does anyone know how to get Poppler on Windows for ScraperWiki?
Other answers have linked to the correct download page for Windows users but do not specify how to install them for the uninitiated.
Go to this page and download the binary of your choice. In this example we will download and use poppler-0.68.0_x86.
Extract the archive file poppler-0.68.0_x86.7z into C:\Program Files. Thus, the directory structure should look something like this:
C:
└ Program Files
└ poppler-0.68.0_x86
└ bin
└ include
└ lib
└ share
Add C:\Program Files\poppler-0.68.0_x86\bin to your system PATH by doing the following: Click on the Windows start button, search for Edit the system environment variables, click on Environment Variables..., under System variables, look for and double-click on PATH, click on New, then add C:\Users\Program Files\poppler-0.68.0_x86\bin, click OK.
If you are using a terminal to execute poppler (e.g. running pdf2image in command line), you may need to reopen your terminal for poppler to work.
Done!
Poppler Windows binaries are available from ftp://ftp.gnome.org/Public/GNOME/binaries/win32/dependencies/ -- but note that those aren't quite up-to-date.
If you're looking for Python (2.7) bindings (as this question's tag suggests), I requested them in the past via this bug report. A couple of people apparently managed to produce something, but I haven't checked those out yet.
As for a more recent (python bindings unrelated) poppler Windows binaries Google result, see http://blog.alivate.com.au/poppler-windows/
Finally, there's the brand-new (and currently very frequently updated) PyGObject all-in-one installer (mainly aiming to provide PyGObject-instrospected Gtk+3 Python bindings etc. for Windows), so if that's what you're looking for, go to http://sourceforge.net/projects/pygobjectwin32/files/?source=navbar
Download Poppler Packaged for Windows
https://github.com/oschwartz10612/poppler-windows/releases
I threw together a quick repo with the latest Poppler prebuilt-binaries packaged with dependencies for Windows. Built with the help of conda-forge and poppler-feedstock. Includes the latest poppler-data.
With anaconda installed on windows one can simply execute:
conda install -c conda-forge poppler
UPDATE 2
See the answer by Owen Schwartz.
UPDATE 1
Rumpel Stielzchen's comment:
This site is no longer maintained. Poppler version 0.68 is very
outdated today. You find the latest version compiled also for Windows
here: https://anaconda.org/conda-forge/poppler/files Sadly there is no
32 bit version, only 64 bit
… but this package contains no dependencies:
It seems that the Anaconda people have a tool to download a package
and all dependencies. And there is a file in the TAR package:
index.json which lists the package on which it depends. I downloaded
the dependencies one by one, and yes: It WAS a pain.
Original answer
Latest Poppler Windows binaries can be found here:
http://blog.alivate.com.au/poppler-windows/
Chocolatey
Poppler is available as Chocolatey package:
choco install poppler
By default Poppler is installed in C:\ProgramData\chocolatey\lib\poppler and shims are automatically created for the following tools: pdfdetach, pdffonts, pdfimages, pdfinfo, pdfseparate, pdftocairo, pdftohtml, pdftoppm, pdftops, pdftotext, pdfunite.
To update Poppler, run:
cup poppler
Scoop
Install from the main bucket:
scoop install poppler
By default Poppler is installed in ~\scoop\apps\poppler and shims are automatically created for the following tools: pdfdetach, pdffonts, pdfimages, pdfinfo, pdfseparate, pdftocairo, pdftohtml, pdftoppm, pdftops, pdftotext, pdfunite.
To update Poppler, run:
scoop update poppler
TeX Live
As mentioned in another answer, MiKTeX currently ships with Poppler tools, and so does another LaTeX distribution, TeX Live.
From the guide:
Command-line tools.
A number of Windows ports of common Unix command-line programs are installed along with the usual TeX Live binaries. These include gzip, zip, unzip, and the utilities from the poppler suite (pdfinfo, pdffonts, …)
Poppler suite is located by default in C:\texlive\<year>\bin\win32 and, if you can compile your LaTeX documents, should work out of the box since this location is added to the PATH by the installer.
To Simply install Poppler on Windows run through the below mentioned steps without touching the environmental varible.
Download the Latest Poppler Binary from the URL: http://blog.alivate.com.au/poppler-windows/index.html
Unzip it and copy the poppler-0.68.0_x86 folder in some path for ex, C:/User/Poppler/poppler-0.68.0_x86/poppler-0.68.0/bin
Now go to your Python code where you want to call Poppler for image conversion and use the below mentioned code snippet:
from pdf2image import convert_from_path
pages = convert_from_path('MyPdf.pdf', 500, poppler_path = r'C:\User\Poppler\poppler-0.68.0_x86\poppler-0.68.0\bin')
for page in pages:
page.save('out.jpg', 'JPEG')
You should consider using Windows Subsystem for Linux (WSL).
Enable WSL on Windows 10 (it will not work on S edition)
Install Ubuntu (latest version) on WSL from the Windows Store
Open Ubuntu command-line
In the Ubuntu Command-line, run the following commands:
sudo apt-get update
sudo apt-get upgrade
sudo apt install poppler-utils
pdftocairo -v - to check the installed version
You can then run pdftocairo (for example) in two ways:
Within the Ubuntu command-line: pdftocairo ...
Directly from Windows command-line: wsl pdftocairo...
NOTE: There is a default version of poppler for each release of Ubuntu. You will need to look up the instructions (there should be plenty on the internet), for how to install the latest version of poppler-utils on Ubuntu. This might involve quite a few steps, which will compile from the source code. For example, something like this https://askubuntu.com/a/722955. And then you might get a lot of problems.
The latest version of Ubuntu 19.04, can install Poppler 74. But Ubuntu 18.04 seems to be the latest version you can install for WSL for now, and that installs Poppler 62.
It looks like a version that is build-able with visual studio can be found here https://bitbucket.org/merarischroeder/poppler-for-windows/overview
Up to date binaries for Windows x64, Mac OSX-64, Linux-64bit can be found here
https://anaconda.org/conda-forge/poppler/files
Poppler version 0.84 is available at the link as of this writing which is very current.
The accepted answer and the link given by Alexey are no longer pointing to current versions of poppler
Update :
As of March 8, 2021 the best answer is by Owen Schwarz above https://stackoverflow.com/a/62615998/590388
Another option is that if you have installed MikTeX then poppler is included by default and is probably already in your PATH. In my case the binaries were installed under: C:\Program Files\MiKTeX 2.9\miktex\bin\x64
MSYS2 has the latest version available for install.
If you don't want to install the whole enviroment (or you wanted some kind of portable version) you could also just download Poppler straight from the repository, but then you'd also have to manually handle dependencies. Namely: libwinpthread, nspr, gcc-libs, nss, curl, brotli, openssl, libidn2, libiconv, gettext, libunistring, nghttp2, libpsl, libjpeg-turbo, lcms2, openjpeg2, libpng, zlib, libtiff, xz and zstd.
Install the Microsoft Visual C++ Build Tools
Install poppler through the Conda prompt conda:
conda install -c conda-forge poppler
please note: if you don't have anaconda installed, it can be downloaded from here,
https://docs.anaconda.com/anaconda/install/windows/

I would like to use the WatchService API as mentioned in this link:
http://download.oracle.com/javase/tutorial/essential/io/notification.html
After reading around, I found out that WatchService is part of the NIO class which is scheduled for JDK 7. So, it is in beta form. It's fine.
http://jdk7.java.net/download.html has the JDK which I downloaded and extracted. I got a bunch of folders. I don't know what to do with them.
Then, I read around some more and found that some nice group of people created JDK 7 as a binary so someone like me can install it easily. It is called Open JDK:
http://code.google.com/p/openjdk-osx-build/
So, I downloaded the .dmg file and install it. Then I open "Java Preference" and see that OpenJDK7 is available.
So, now I feel that I can start trying out WatchService API. From the tutorial in the first link, the author gave a .java file to test it out first and make sure that it is running. Here is the link to the file:
http://download.oracle.com/javase/tutorial/essential/io/examples/WatchDir.java
So, I boot up Eclipse (actually I use STS) and create a new Java project and choose JaveSE-1.7 in the "use an execution environment JRE:". Under the src folder, I copy pasted the WatchDir.java file.
And I still see tons of squiggly red lines. All the "import.java.nio.*" are all red and I cannot run it as a Java app.
What do I need to do?
This is how I got 1.7 to work with Eclipse. I hope it helps.
I Downloaded the latest OpenJDK 1.7 universal (32/64 bits) JDK
from Mac OS/X branch from http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
copied the jdk to /Library/Java/JavaVirtualMachines/ next to the
default 1.6.0 one
In Eclipse > Preferences > Java > Installed JREs you add a new one, of type MacOS X VM, and set the home as /Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home and
name Java SE 7 (OpenJDK)
Click Finish
Set the added JRE as default
that should be it :)
Oracle has released JDK 7 for OS X.
Java 9, 10, 11
Years ago, Apple joined the OpenJDK project, transferring their formerly proprietary macOS-specific JVM code as free-of-cost open-source. Apple ceased distribution of their own branded JVM/JDK, relying on Oracle’s branded releases to include a version for macOS.
Oracle has recently announced their intention to bring their Oracle-branded JVM release to feature parity with the OpenJDK project, with virtually the same code base. The company even donated their previously commercial tools, Flight Recorder & Mission Control, to the OpenJDK project. This is part of the shift to a new rapid “release train” plan for predictably scheduled versioning of Java and OpenJDK. Notably, the periods for free-of-cost public updates is now shortened. See this 2017-09 announcement and this posting by Mark Reinhold.
As a result of all this, macOS users of Java have a choice of vendors for a Java implementation. At this point, at least three sources are based on OpenJDK for macOS:
Oracle releases of the JDK and JRE, with optional paid support.
Azul Systems releasing:
Zulu line of free-of-cost JVMs with optional paid support.
Zing line of commercial JVMs with special features such as an alternate garbage-collector.
OpenJDK source code, roll-your-own compilation & installation (perhaps not practical for most of us).
Meanwhile, IBM donated code for a JVM to the Eclipse Foundation, now housed in the OpenJ9 project. I wonder if they might support a macOS release as well, though it is too soon to tell.
Personally, I am currently using the Zulu release of Java 10.0.1 from Azul on macOS High Sierra successfully with IntelliJ 2018.2 to produce Java-backed web apps with Vaadin.
Installation/Removal
Both Oracle and Azul provide utterly easy-to-use installers to install the JVM/JDK on your Mac. Verify your installation by using the Terminal.app (or equivalent) to type and run:
java -version
You will find the Java installations in this folder at the root level of your drive (not in your home folder):
/Library/Java/JavaVirtualMachines
Each version from each vendor is found there, in a labeled nested folder. You can delete any installation simply by deleting the nested folder for that version and providing your system password when prompted.
Java 8
You can download the Java Development Kit (JDK) for Java 8 for the supported versions of Mac OS X:
Mountain Lion (10.8.3+)
Mavericks (10.9)
Yosemite (10.10)
El Capitan (10.11)
Each version of JVM you install can be found here:
/Library/Java/JavaVirtualMachines
For more instructions and FAQ, see this Oracle Guide.
Java 7
For every release of Java 7 since Update 4, a Mac version has been ready alongside the other platforms. Runs on Macs with 64-bit hardware on Lion (10.7.3+), Mountain Lion (10.8.3+), and Mavericks (10.9.x).
Oracle announced the official release of the JDK for Java SE 7 Update 4 on Mac OS X (Lion), as of 2012-04-26. No more need for the tricks discussed on this page.
Installation is simple per these instructions:
Download from the usual place on the Oracle web site.
Mount the DMG.
Run the installer.
This release has a few limitations, most notably the lack of support for Java Web Start and the Java Plugin for web browsers. That support is expected later this year.
After installing, read the JDK for Mac ReadMe. Most importantly, if you want Java 7 to be the default, drag it to the top of the list in the Java Preferences app found in your Utilities folder.
Mac OS X easily supports multiple JVMs simultaneously. Each is now found here:
/Library/Java/JavaVirtualMachines
Congratulations to the Apple & Oracle teams for their achievement. This geek gets a thrill seeing Mac OS X listed as a "Certified System Configuration".
Tip: To start Eclipse on a Mac with only Java 7 installed, open the alias file named eclipse rather than the file named Eclipse.app.
Java 6
Apple continues to supply an up-to-date implementation of Java 6 for all versions of Mac OS X up through Mountain Lion.
If you do something that requires Java, such as type "java -version" in Terminal.app, a dialog appears offering to install Java for you. If you accept, installation happens automatically similar to other "Software Updates" from Apple.
You will find Java installed in this location, different than Java 7 & 8:
/System/Library/Java/JavaVirtualMachines
Java 6 has reached end-of-life with Oracle as of 2013-02 (unless you have a commercial support agreement with Oracle). So you should be moving to Java 7 or 8.
Testing New Version
In Terminal.app, type java -version to verify which version is the current default.
Deleting Old Versions
After installing a fresh version, you may want to visit the folder described above to delete old versions. Move the folder to the Trash, and provide your System password complete the move.
By the way, Apple provides a mailing list for developers’ technical issues related to Java on OS X.
An easy way to install Java 7 on a Mac is by using Homebrew, thanks to the Homebrew Cask plugin (which is now installed by default).
Run this command to install Java 7:
brew cask install caskroom/versions/java7
Get cask
brew tap caskroom/cask
Install java7:
brew tap caskroom/versions
brew cask install java7
(I had difficulty finding the download link of java7 on oracle website, as they're just "recommending" java8 )
EDIT January 2018 (As pointed by Ankur):
Use zulu7 cask. Zulu is a certified build of OpenJDK produced by Azul Systems that should be around for a long time (they even offer JDK6 builds still).
brew cask install caskroom/versions/zulu7
I know that some may want to smack me for re-opening old post, but if you feel so do it I just hope this may help someone else trying to set JDK 7 on Mac OS (using IntelliJ).
What I did to get this working on my machine is to:
followed instructions on Oracle JDK7 Mac OS X Port for general installation
in IntelliJ open/create new project so you can add new SDK (File > Project Structure)
select Platform Settings > SDKs, press "+" (plus) sign to add new SDK
select JSDK and navigate to /Library/Java/JavaVirtualMachines/JDK 1.7.0 Developer Preview.jdk/Contents/Home. Do not get it mistaken with /Users/YOUR_USERNAME/Library/Java/. This will link 4 JARs from "lib" directory (dt.jar, jconsole.jar, sa-jdi.jar and tools.jar)
you will need also add JARs from /Library/Java/JavaVirtualMachines/JDK 1.7.0 Developer Preview.jdk/Contents/Home/jre/lib (charsets.jar, jce.jar, JObjC.jar, jsse.jar, management-agent.jar, resources.jar and rt.jar)
after installing the 1.7jdk from oracle, i changed my bash scripts to add:
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_13.jdk/Contents/Home
and then running java -version showed the right version.
It's possible that you still need to add the JDK into Eclipse (STS). Just because the JDK is on the system doesn't mean Eclipse knows where to find it.
Go to
Preferences > Java > Installed JREs
If there is not an entry for the 1.7 JDK, add it. You'll have to point Eclipse to where you installed your 1.7 JDK.
If Eclipse can't find a JRE that is 1.7 compatible, I'm guessing that it just uses your default JRE, and that's probably still pointing at Java 1.6, which would be causing your red squiggly lines.
I needed to adapt #abe312's answer since there has been some changes with brew lately.
I installed zulu7 and setup JAVA_HOME by running:
brew install --cask homebrew/cask-versions/zulu7
echo "export JAVA_HOME=/Library/Java/JavaVirtualMachines/zulu-7.jdk/Contents/Home" >> ~/.zshrc
I had to enter my password for installing zulu7. You may need to modify the last command if you are using a different shell.
How about Netbeans, here is an article how to set it up with NB7:
http://netbeanside61.blogspot.com/2011/06/downloading-openjdk7-binary-for-mac-os.html
Maybe similar steps for Eclipse.
As of April 27th there is an offical Oracle release of Java SE 7u4. Download the disk image and run the installer - then see the Mac readme.
As of December 2017, previously posted links don't work, but JDK 7 can still be downloaded from Oracle Archives (login required):
http://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase7-521261.html
The instructions by peter_budo worked perfectly. I had to add the jars under /Library/Java/JavaVirtualMachines/JDK 1.7.0 Developer Preview.jdk/Contents/Home/jre/lib/ to my IntelliJ project libraries. Now it works like a charm. Note that I didn't need my IDE itself to run under 1.7; rather, I only needed to be able to compile and run against 1.7. I'll most likely continue to use Apple's JRE for running the IDE since it's probably more stable with respect to graphics routines (Swing, AWT). Like the OP, I was really keen on testing out the new NIO2 API. Looking good so far. Thanks, Peter.
What worked for me on Lion was installing the JDK7_u17 from Oracle, then editing ~/.bash_profile to include:
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_13.jdk/Contents/Home
Now, Use command
Update 2020: 04
To install Java7 with homebrew run:
brew tap homebrew/cask-versions
brew cask install java7
Hope this help.
I updated to Yosemite and Android Studio wouldn't clean my projects or Run them on virtual or real device because of the following error:
Failed to complete Gradle execution.Cause:Supplied javaHome is not a valid folder. You supplied: /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
After some research and trouble shooting, I found that the JDK file that was being pointed to at "/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home" wasn't there; all of "JavaVirtualMachines/1.6.0.jdk/Contents/Home" was missing from "/System/Library/Java". So, I copied "JavaVirtualMachines/1.6.0.jdk/Contents/Home" over from "/Library/Java/" to "/System/Library/Java/" and cha ching! I was back in business.
