I followed this guide to use paperclip http://railscasts.com/episodes/134-paperclip?language=en&view=asciicast
it is all ok but note that to enable resizing you’ll need to have ImageMagick installed on your server.
So how should i install ImageMagick ?? i have WINDOWS 8 and on the site http://www.imagemagick.org/ download does not work!!!!
It certainly works - you need to make sure of 2 things:
You install the correct static version for your OS (32-bit vs 64-bit). The 32-bit (x86) will work regardless, the 64-bit (x64) will only work on a 64-bit system. And you need to download the static version - not the -dll version - as Paperclip needs to call the executable directly. (Of course, I'm sure that you knew that downloading the installer file isn't going to install it for you, right? That is, you need to open the file to start the installation...)
You add the bin directory to your environment path. The installer should do this for you, unless you unchecked that option.
UPDATE
Just noticed that the links are broken :) They still point to the older 6.8.5-6 version that have since been moved to legacy. You can get the latest binaries from here.

I have already installed MinGW32. I want to update MinGW32, GCC, and G++ on the latest available version. I have searched on the internet and overflow but the answers seem to be outdated. One of the answers, I tried but it shows the same version of MinGW and GCC( latest version is 10.2 and I have 9.2.0) as before.
Moreover, my machine is 64 bit so I want to upgrade my MinGW to MinGW64 but despite lots of efforts and internet searches, I am unable to get an executable setup for the system, neither cmd instructors to install. Also, I am unable to discover instructions for its updating to the latest version available( for future purposes)
Please help me to accomplish the above tasks. Also, it would be better if the step by step instructors are provided using cmd. Thanks in advance.
The MinGW-w64 personal build from http://winlibs.com/ has the latest GCC version (currently 10.1) and requires no installation, just unzip the download.
If you need to upgrade this later you can just replace the mingw32 or mingw64 folder with the new version.
I installed pgAdmin 4 as part of the postgres installer for Windows. pgAdmin is now telling me there is a newer version (4.8, > 4.5 which I have). However, there is no built in upgrade functionality that I can see, and when I went to download and run the pgAdmin 4 installer to upgrade, it installed itself in the wrong place, leading to problems.
At first I tried installing it to the default location (C:\Program Files (x86)\pgAdmin 4\v4), which was incorrect, because the previous installation (from the postgres installer) went to a different location (C:\Program Files\PostgreSQL\11\pgAdmin 4).
The second time, I pointed it to my existing install of postgres (C:\Program Files\PostgreSQL\11\pgAdmin 4), but it installed itself to a subdirectory there instead (C:\Program Files\PostgreSQL\11\pgAdmin 4\v4), rather than upgrading the existing installation, once again yielding to duplicated installations and problems arising from that. I assume if I go download the postgres installer, it will just reinstall version 4.5 of pgAdmin, though I have not tested this.
What is the correct method for upgrading a pgAdmin instance originally installed by the postgres Windows installer?
I think the best option is to go to Program and files -> Select PostgreSQL and "Uninstall".
Uninstaller will ask you if you want to uninstall the whole application or only individual components. Select individual components and then select pgAdmin.
This will uninstall pgAdmin from PostgreSQL directory.
From now, install the latest version pgAdmin only from official website which will install it into: C:\Program Files (x86)\pgAdmin 4\v4
If you Download the installer from here https://www.postgresql.org/ftp/pgadmin/pgadmin4/v4.8/windows/
It should automatically install the 4.8 version in (C:\Program Files (x86)\pgAdmin 4\v4)
overwriting any existing 4.x version but keeping your server connections and setting.
In your case, the previous install was in a different place, therefore, you ended up having 2 versions.
What I suggest to you is go to control panel and uninstall from there all the versions you have. After that go to the above link, download and install the v4.8 in the default location. Every time there is a new version available just install it and let the installer install it on the default location.
Please note that your pgadmin server connections can be found in %appdata%\pgAdmin.
Note that I have personally just upgraded from v4.5 to v4.8 using this method (installing it in the default location) and it worked like a charm.
Not sure the best approach here.
If you update directly pgadmin from: https://www.postgresql.org/ftp/pgadmin/pgadmin4/v4.10/windows/ the installation goes into
"C:\Program Files (x86)\pgAdmin 4\v4\runtime\pgAdmin4.exe"
Wheras the installation of the whole EnterpriseDB Installer from:
https://www.enterprisedb.com/downloads/postgres-postgresql-downloads is installed here:
"C:\Program Files\PostgreSQL\11\pgAdmin 4\bin\pgAdmin4.exe"
This looks like a wholly undesirable conflict? And leads to the problem identified by #Anomaly ?
To anyone finding this post (like me), before uninstalling your current pgAdmin 4, be aware that there may be limits on compatible versions based on your version of PostgreSQL. Following the instructions by Claudio Corchez, I removed my existing pgAdmin 4 and downloaded the latest 6.15. When I attempted to install it, the installer informed me that this version was not compatible with my version of PostgreSQL 10.3. So, I headed back and downloaded 4.30, which is now running. Unfortunately, it warns me each time I run it that a newer version is available. I just need to upgrade my entire PostgreSQL installation.
I had the same issue previously, and had to manually select the path.
Apparently now (v. 4.25) it auto-detects the path and updates correctly.
I had to download from the website, there was no update button embedded in pgAdmin itself
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.
Having deleted the Studio 3, which was working, and installing a new one, the first launch produced the message: "Failed to load the JNI Shared Library: 'C:...java.jdk1.8.0_05\bin..\jre\bin\server\jvm.dll'" Upon checking the indicated bin directory, the 'server' subdirectory was missing. I then installed both jre7 and jre8 as standalone jre's. Both hre7 and jre8 have the server subdirectory under bin. If I point JAVA_HOME towards one of the newer installs, I will lose ready access to the JDK. Is there any other way to tell Aptana Studio 3 which jvm to use?
This whole exercise was started in an attempt to get Aptana Studio 3 to use Ruby 2.0.0, rather than ruby 1.9.3 (both of which are installed). How might one do that? Both rubys are in the PATH, with ruby2.0.0 first. Also RUBY_HOME points to ruby2.0.0. Entering ruby -v at the command prompt yields 1.9.3.
In turn, I am doing this because I am getting a crash in 1.9.3 wich says: "You have encountered a bug in the ruby interpreter..."
You can configure which version of Java Aptana will use in AptanaStudio3.ini: simply add
-vm
C:/Program Files (x86)/Java/jdk1.7.0_21/bin/javaw.exe
(before --launcher.XXMaxPermSize) pointing to a 32bit Java version.
Make sure you have the 32-bit version of the JDK installed. This error occurs with the 64-bit version. Try and download the 32bit JDK, install and Aptana should run (at least that worked for me)
The latest Windows installer does not contain the JRE, contrary to what the page at http://www.aptana.com/products/studio3/success.html says:
The Windows installer includes a compatible version of Java.
I downloaded the 3.5 installer, installed to a different directory, and copied the JRE directory from there to the 3.6.x directory. This has resolved the issue for me.
(I suppose the installer could contain a 32-bit JRE, detect my system is a 64-bit system, and not install it, but the size difference between the two installers is enough to be accounted for by a missing JRE.)
I Was getting the same issue while loading aptana.
Fixed it with following steps.
Uninstalled available jdk7.1 (It was 64 bit)
Uninstalled aptana;
Downloaded and installed jdk7.1 32 bit.
The jvm.dll will be in the follwing path: "C:\Program Files (x86)\Java\jdk1.7.0_75\jre\bin\client"
Re installed aptana
Thanks
I'm using wamp server v2.2 x64 and php version 5.3.13. I'm trying to install ffmpeg during two days. I fallowed this steps:
Download dll files for x64 (I'm using windows7 x64)
copied ffmpeg.dll to bin\php\php5.3.13\ext
copied rest of dll files to system32
enable ffmpeg extension from wamp server.
and I checked phpinfo() but it's not working.
by the way is there any way to take a frame from video for poster image ?
In order to get php_ffmpeg working you are going to have to find someone that has recompiled it with the VC9 compiler for 64bit and in a thread safe way.
You may find this difficult, I cannot find anything out there yet having just googled around for it.
You would find it easier if you un-install WAMP 64bit and install the WAMP 32bit. There is a php_ffmpeg.dll available in that environment
PS There is no issue with running 32bit WAMP on a 64bit OS.
