Installing HTCondor

This page discusses building and installing HTCondor from source code. There are many options for installing pre-compiled binaries, which are generally easier and faster, those are documented in the manual

Building on Linux inside a build container

Building using a container with dependencies and compilers preinstalled:

There are many dependencies that must be installed before compiling the HTCondor source code. These change from time to time, so any document is likely to be out of date. The official binaries are built inside containers which are kept up to date. So, the easiest way to build HTCondor from source is using one of these containers. The list of these containers is located in the source code

Picking one for example, docker://htcondor/nmi-build:x86_64_Ubuntu22-10040004, which is surely out of date by the time you are reading this:

Launch the build container:

docker run --rm=true --user your_username -t -i htcondor/nmi-build:x86_64_Ubuntu22-10040004 /bin/bash

Inside the container, cd into your home directory, and git clone the source code:

cd /tmp
git clone https://github.com/htcondor/htcondor

After the code is downloaded, make a __build directory (note that the source code already has a directory named build, so that can't be used). Then use that directory to configure cmake and launch the build:

cd htcondor
mkdir __build
cd __build
cmake ..
make -j 8 install

And that's it! Enjoy!

Building on Linux outside of a container

If you'd like to build outside of a container, on raw hardware, then several dependencies will need to be installed. HTCondor often requires a newer version of the system compiler than ships with older distributions, so the devtoolset compiler may need to be installed. For a complete list of these dependencies, we recommand looking at the dockerfile we use to build the container above, this script generates those.

Building HTCondor on Windows

  1. Install your tools (make sure to have their paths added to system path)

  2. Configure your environment

    • a) You can invoke any shell you wish but make sure that the paths to the tools are available. Additionally you should add an additional path (b) for building in Windows. These can be added after the source code is on the system since the paths are relative to the condor source.
        1. I use the command prompt shell provided with Visual Studio installation. This sets up the paths to the Visual Studio toolsets automatically. e.g.
         "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Microsoft Visual Studio 2012\Visual Studio Tools\Developer Command Prompt for VS2012.lnk"
    • b)Add <PATH_TO_CONDOR_SRC>\condor\msconfig to path

  3. Get the source code.

    • a) in an environment shell change directories to where you would like the condor folder created by the git clone command.
    • b) clone the condor repository 
       git clone https://github.com/htcondor/htcondor

    This will take a while and once done you will have the condor source tree in the current working directory.

    • remember to add the condor\msconfig to your path

  4. build condor There are 2 methods to build condor 1. in source build and 2. out of source build

    • a) in source build This method builds the binaries within the source tree.
      1. cd to within the condor folder.
      2. Generate the Visual Studio solution files with CMake 
        cmake -G "Visual Studio 11 2012"
    • b) out of source builds This method preserves the source tree and creates all files out side of the source tree
        1. cd to within the condor folder and set _condor_sources environment variable
         cd condor
 set _condor_sources=%CD%
        1. Make a directory somewhere else you would like to build and cd there
         md c:\src\build_dest
 cd /d c:\src\build_dest
        1. Generate the Visual Studio solution files with CMake
         cmake CMakeLists.txt -G "Visual Studio 11 2012" %_condor_sources%
    • c) Build condor
        1. within the IDE
        • a) Launch Visual Studio editor and open the CONDOR.sln
        • b) Select the build type Debug or RelWithDebInfo (Release is being deprecated)
        • c) Choose the All_BUILD project
        • d) build
        1. with the command line
        • a) With devenv 
           devenv CONDOR.sln /Build RelWithDebInfo
        or
 devenv CONDOR.sln /Build Debug
        • b) With msbuild 
           msbuild CONDOR.sln /t:ALL_BUILD /p:Configuration:RelWithDebugInfo
         or
 msbuild CONDOR.sln /t:ALL_BUILD /p:Configuration:Debug

  5. Creating installer An msi style installer can be created with included scripts and with the aid of the Wix tools.

    • a) Copy the build sources to an installer staging area with cmake. (this will create a directory at the CMAKE_INSTALL_PREFIX path) 
       cmake -DBUILD_TYPE=RelWithDebInfo -DCMAKE_INSTALL_PREFIX:PATH=c:\src\installer\release_dir -P cmake_install.cmake
    • b) Change directory to the copied location and run the do_wix.bat batch file 
       cd c:\src\installer\release_dir
 etc\WiX\do_wix.bat %CD% c:\src\installer\Condor_installer.msi
