I'm trying to download debugging symbols to Debian OS, I've done some research and saw this web : https://wiki.debian.org/HowToGetABacktrace , but i could not know the name of the package to download it. Please help me.
This depends on what app you want to debug. Say you want to debug /bin/ls.
First you need to find out what package provides this file:
$ dpkg -S /bin/ls
coreutils: /bin/ls
Package name is coreutils. Next you need to install debug symbols for this package following instructions in https://wiki.debian.org/HowToGetABacktrace#Installing_the_debugging_symbols. It should be either coreutils-dbgsym or coreutils-dbg package. So the command to install debug symbols package would be one of these:
# apt-get install coreutils-dbgsym
or
# apt-get install coreutils-dbg

I've freshly installed Ubuntu 18.04 and have decided to try Anaconda. However, when I then try to install Mendeley, I get the following error:
mendeleydesktop depends on python; however:
Package python is not installed.
I assume the issue here is that python is now in ~\anaconda2\bin, instead of \usr\bin. I'm not certain what I should do. As I see it, I have 3 options:
Install a system python into \usr\bin, but this seems sloppy/messy
Put a softlink in \usr\bin along the lines of ln -s python ~\anaconda2\bin\python, but I'm worried that there might be implications to that, which I don't understand
Somehow tell the mendeley.deb file where the python I'm using is, but I don't know how to do this.
Are either 1 or 2 reasonable options? If not how do I implement my 3rd option, or what else should I do?
Empirically found option 2 does not work. dpkg is still looking for the installation of the python package
You can use the method given here to remove the system python dependency in the .deb file; I tried this and mendeley seems to install as normal. Assuming your conda environment is set up correctly, it will work. I had to modify the instructions on that page slightly:
Unpack deb: $ ar x mendeleydesktop_1.19.4-stable_amd64.deb (will create i.e. three files: debian-binary control.tar.gz data.tar.gz)
Unpack control archive: $ tar xzf control.tar.gz (will create: postinst control)
Fix dependencies in control (use a text editor)
Repack control.tar.gz: $ tar c postinst control | gzip -c > control.tar.gz
Repack deb: $ ar rcs mendeleydesktop_1.19.4-stable_amd64_nopythondep.deb debian-binary control.tar.gz data.tar.gz (order important! dpkg wouldn't be able to read the metadata of a package quickly if it had to search for where the data section ended!)
I'm desperately trying to compile Tesseract-ocr (4.0) on a Windows Machine with some restrictions.
We are doing multi-platforms : an automated compilation must be possible (command-line)
We are using specific 3rd party libraries : the compilation must accept custom path / libraries for most of its dependencies
We are already using most of the 3rd party libraries for other part of the code : the compilation must not recompile them (thus, no cppan)
Leptonica has been built with our special 3rdparty (ZLib, LibPng ..)
Our project must "include" tesseract alongside theses specific 3rdparty
Problem :
I have strong issue specifying custom paths for Tesseract.
Under Unix (CentOS, Ubuntu 16/18, Debian 8/9 ..), I was able to achieve my goal with the tools autogen autoconf autoheaders pkg-config.
Under Windows, autoconf-archive and pkg-config are unavailable (from what I tried) ; rendering autoconf unusable.
I was neither able to compile using CMake and specifying a custom path for Leptonica (even after writing a new pkgconfig for leptonica).
Things I tried :
Using MinGW and autoconf
Manually installing pkg-config
Cheating with autoconf-archive .m4 into aclocal
Creating a VisualStudio project with cppan and modify it
Various ways of telling CMake to search elsewhere for 3rdparty
Things that work on Linux :
Autoconf with modified PKGConfig for custom compiled Leptonica (--with-extra-libraries PKG_CONFIG_PATH CPPFLAGS LDFLAGS)
Things I have not tried :
Installing Leptonica on the machine (Not the point here)
Rewriting CMakeFiles
Unknown solutions ?
Possible Solutions
MinGW (Windows) with pkg-config autoconf-archive
Unknown way to tell CMake Leptonica custom path
VisualStudio project without cppan
Yours ?
Thank your for your interest.
EDIT 1
By trying various ways of manually installing pkg-config, Autoconf seemed to be unaware of its presence. This error was about pkg-config missing package (How to install pkg config in windows?).
CPPAN was deeply part of the visual studio project and I couldn't see how I could separate them.
I usually tell configure to look for leptonica package with the arguments --with-extra-libraries and PKG_CONFIG_PATH.
CMake however, uses the "macro" find_package(Leptonica $PATH CONFIG REQUIRED). By looking at it a little bit, I was (maybe) able to specify its path with CMAKE_PREFIX_PATH, CMAKE_MODULE_PATH, Leptonica_DIR. The compilation was still unsuccessfull due to missing config files (LeptonicaConfig.cmake or leptonica-config.cmake).
I pointed theses variables to various folders of the leptonica folder after building it.
For information, I built Leptonica with its configure as such :
bash configure --enable-shared=false --without-giflib --without-libwebp --without-libopenjpeg LDFLAGS="-LPATH/TO/ZLIB -LPATH/TO/LIBPNG .." CPPFLAGS="-IPATH/TO/ZLIB/INCLUDE ..."
I, however, was unable to locate theses files (while seeing a LeptonicaConfig.cmake.in under LeptonicaDir/cmake/template)
I hope I answered your questions. Please tell me if you need further details.

I have tried to install openAFS directly from source code. This is for a MAC with OS Yosemite and I followed the instructions from an earlier question of mine:
https://stackoverflow.com/questions/26959675/afs-and-yosemite-on-mac
However I can do everything until: sudo make packages, were I get the error:
packagemaker not found
make: *** [packages] Error 1
I looked into where this error occurs and it wants something in:
/Developer/usr/bin/packagemaker
Do I need another piece of software to finish this installation?
thanks,
Alex.
Yes, you need PackageMaker installed. Note that this isn't technically required to build OpenAFS, but it is required to build the installer packages, which you probably want to do.
To install PackageMaker:
Download "Auxiliary Tools for Xcode - Late July 2012" from somewhere in developer.apple.com. I think this is somewhere in here.
Copy PackageMaker.app into /Applications/Utilities
Run:
$ sudo ln -s /Applications/Utilities/PackageMaker.app/Contents/MacOS/PackageMaker /Developer/usr/bin/PackageMaker
Then you should be able to make packages in the OpenAFS source tree.

I would like to install the older version of Google Protocol Buffers (protobuf-2.4.1) on Mac using the command line/Terminal app.
I tried with brew install protobuf, but the latest version 2.5.0 has been installed.
Is it possible to install the older version from the terminal?
There are some issues with building protobuf 2.4.1 from source on a Mac. There is a patch that also has to be applied. All this is contained within the homebrew protobuf241 formula, so I would advise using it.
To install protocol buffer version 2.4.1 type the following into a terminal:
brew tap homebrew/versions
brew install protobuf241
If you already have a protocol buffer version that you tried to install from source, you can type the following into a terminal to have the source code overwritten by the homebrew version:
brew link --force --overwrite protobuf241
Check that you now have the correct version installed by typing:
protoc --version
It should display 2.4.1
This is not via brew, but the end result is the same.
Download the protobuf-2.4.1 from https://github.com/protocolbuffers/protobuf/releases/tag/v2.4.1
Extract the tar.gz file.
$cd ~/Downloads/protobuf-2.4.1
$./configure
$make
$make check
$sudo make install
$which protoc
$protoc --version
Steps 4-7 are from the README.txt file from the protobuf tarball.
If you landed here looking for how to install Protocol Buffers on Mac, it can be done using Homebrew by running the command below
brew install protobuf
It installs the latest version of protobuf available. For me, at the time of writing, this installed the v3.7.1
If you'd like to install an older version, please look up the available ones from the package page Protobuf Package - Homebrew and install that specific version of the package.
The oldest available protobuf version in this package is v3.6.1.3
It's a new year and there's a new mismatch between the version of protobuf in Homebrew and the cutting edge release. As of February 2016, brew install protobuf will give you version 2.6.1.
If you want the 3.0 beta release instead, you can install it with:
brew install --devel protobuf
For some reason I need to use protobuf 2.4.1 in my project on OS X El Capitan. However homebrew has removed protobuf241 from its formula. I install it according #kksensei's answer manually and have to fix some error during the process.
During the make process, I get 3 error like following:
google/protobuf/message.cc:130:60: error: implicit instantiation of undefined template 'std::__1::basic_istream<char, std::__1::char_traits<char> >'
return ParseFromZeroCopyStream(&zero_copy_input) && input->eof();

class _LIBCPP_TYPE_VIS basic_ostream;
^
(Sorry, I dont know how to attach code when the code contains '`' )
If you get the same error, please edit src/google/protobuf/message.cc, add #include <istream> at the top of the file and do $ make again and should get no errors. After that do $ sudo make install. When install finished $protoc --version should display the correct result.
From https://github.com/paulirish/homebrew-versions-1 . Works for me!
brew install https://raw.githubusercontent.com/paulirish/homebrew-versions-1/master/protobuf241.rb
I used macports
sudo port install protobuf-cpp
To install Protocol Buffer (as of today version v3.7.0)
Go to this website
download the zip file according to your OS (e.g.: protoc-3.7.0-osx-x86_64.zip). This applies also to other OS.
Move the executable in protoc-3/bin/protoc to one of your directories in PATH. In Mac I suggest to put it into /usr/local/bin
Now your good to go 💪🏾
(optional) There is also an include file, you can add. This is a snippet of the README.md
If you intend to use the included well known types then don't forget to
copy the contents of the 'include' directory somewhere as well, for example
into '/usr/local/include/'.
Please refer to our official github site for more installation instructions:
https://github.com/protocolbuffers/protobuf
brew install --devel protobuf
If it tells you "protobuf-2.6.1 already installed":
1. brew uninstall --devel protobuf
2. brew link libtool
3. brew install --devel protobuf
There is another official way by Google, as mentioned by another user.
Read it fully before trying.
Here are the steps:
Open Terminal and type the following
PROTOC_ZIP=protoc-3.7.1-osx-x86_64.zip
curl -OL https://github.com/google/protobuf/releases/download/v3.7.1/$PROTOC_ZIP
sudo unzip -o $PROTOC_ZIP -d /usr/local bin/protoc
rm -f $PROTOC_ZIP
Worked for me.
P.S.
This is for version 3.7.1 in osx only.
If you want to install some other version/platform, visit the releases link and check out the details of the latest version, and use those information.
Reference
FWIW., the latest version of brew is at protobuf 3.0, and doesn't include any formulae for the older versions. This is somewhat "inconvenient".
While protobuf may be compatible at the wire level, it is absolutely not compatible at the level of generated java classes: you can't use .class files generated with protoc 2.4 with the protobuf-2.5 JAR, etc. etc. This is why updating protobuf versions is such a sensitive topic in the Hadoop stack: it invariably requires coordination across different projects, and is traumatic enough that nobody likes to do it.
HomeBrew versions has been removed and formulaes have been emptied. Therefore, my advice is to install it manually following the following steps.
For the time being you will need to build and install the Protocol Buffers toolset manually.
Download source code: https://github.com/google/protobuf/releases/download/v2.4.1/protobuf-2.4.1.tar.gz
tar xvfz protobuf-2.4.1.tar.gz
cd protobuf-2.4.1
Run ./configure
Edit src/google/protobuf/message.cc, add #include at the top of the file
Run make command from root of the folder, i.e. protobuf-2.4.1/
Run sudo make install
Run /usr/local/bin/protoc --version to check the version of protobuf compiler version
The terminal output should be:
Version: libprotoc 2.4.1
you can install from official link page provided by google http://google.github.io/proto-lens/installing-protoc.html
For v3 users.
http://google.github.io/proto-lens/installing-protoc.html
PROTOC_ZIP=protoc-3.7.1-osx-x86_64.zip
curl -OL https://github.com/protocolbuffers/protobuf/releases/download/v3.7.1/$PROTOC_ZIP
sudo unzip -o $PROTOC_ZIP -d /usr/local bin/protoc
sudo unzip -o $PROTOC_ZIP -d /usr/local 'include/*'
rm -f $PROTOC_ZIP
There should be better ways but what I did today was:
Download from https://github.com/protocolbuffers/protobuf/releases (protoc-3.14.0-osx-x86_64.zip at this moment)
Unzip (double click the zip file)
Here, I added a symbolic link
ln -s ~/Downloads/protoc-3.14.0-osx-x86_64/bin/protoc /usr/local/bin/protoc
Check if works
protoc --version
A friend sent me along this great tutorial on webscraping The New York Times with R. I would really love to try it. However, the first step is to install a package called [RJSONIO][2] from source.
I know R reasonably well, but I have no idea how to install a package from source.
I'm running macOS (OS X).
If you have the file locally, then use install.packages() and set the repos=NULL:
install.packages(path_to_file, repos = NULL, type="source")
Where path_to_file would represent the full path and file name:
On Windows it will look something like this: "C:\\RJSONIO_0.2-3.tar.gz".
On UNIX it will look like this: "/home/blah/RJSONIO_0.2-3.tar.gz".
Download the source package, open Terminal.app, navigate to the directory where you currently have the file, and then execute:
R CMD INSTALL RJSONIO_0.2-3.tar.gz
Do note that this will only succeed when either: a) the package does not need compilation or b) the needed system tools for compilation are present. See: R for Mac OS X
You can install directly from the repository (note the type="source"):
install.packages("RJSONIO", repos = "http://www.omegahat.org/R", type="source")
A supplementarily handy (but trivial) tip for installing older version of packages from source.
First, if you call "install.packages", it always installs the latest package from repo. If you want to install the older version of packages, say for compatibility, you can call install.packages("url_to_source", repo=NULL, type="source"). For example:
install.packages("http://cran.r-project.org/src/contrib/Archive/RNetLogo/RNetLogo_0.9-6.tar.gz", repo=NULL, type="source")
Without manually downloading packages to the local disk and switching to the command line or installing from local disk, I found it is very convenient and simplify the call (one-step).
Plus: you can use this trick with devtools library's dev_mode, in order to manage different versions of packages:
Reference: doc devtools
From CRAN, you can install directly from a GitHub repository address. So if you want the package at https://github.com/twitter/AnomalyDetection, using
library(devtools)
install_github("twitter/AnomalyDetection")
does the trick.
In addition, you can build the binary package using the --binary option.
R CMD build --binary RJSONIO_0.2-3.tar.gz
If you have source code you wrote yourself, downloaded (cloned) from GitHub, or otherwise copied or moved to your computer from some other source, a nice simple way to install the package/library is:
In R
It's as simple as:
# install.packages("devtools")
devtools::install('path/to/package')
From terminal
From here, you can clone a GitHub repo and install it with:
git clone https://github.com/user/repo.git
R -e "install.packages('devtools');devtools::install('path/to/package')"
Or if you already have devtools installed, you can skip that first bit and just clone the repo and run:
R -e "devtools::install('path/to/package')"
Note that if you're on ubuntu, install these system libraries before installing devtools (or devtools won't install properly).
