Building HTCondor with cmake on Windows
These instructions are designed for building HTCondor 8.8 or later on Windows 10 64-bit with Visual Studio 2017.
You can download Windows VMs directly from Microsoft's developer site. These are free and full-featured, however they expire after 90 days.
In order to build HTCondor on Windows, the following prerequisites are required. They need to be in the PATH before you can build. There is a batch file
msconfig\set_build_env.bat in the HTCondor sources that will locate the installed prerequisites and set the PATH for you if you don't wish to add them to your global PATH.
- [Optional] Install 7-zip (64-bit). Add it to your PATH. 7-zip is not needed to build, but it is needed to make the HTCondor .ZIP file. You will not be able to build the PACKAGE target witout 7-zip.
- [Optional] Install git (64-bit) and add it to your PATH, git is one way to get the HTCondor sources. It is not needed if you already have the sources.
- You need to set a configuration option to preserve existing line endings. You can either do this during installation, or later by running from the command line:
git config --global core.autocrlf false
- Install Active Perl. Add it to your PATH.
- NOTE: Cmake is now bundled with Visual Studio 2017. You don't need to install it separately anymore.
- Install Visual Studio 2017 Community Edition.
- https://visualstudio.microsoft.com/free-developer-offers/ (free for all non-enterprise users)
- During the installation, under Workloads->Windows check Desktop Development with C++
- Under the list of Optional components on the right side of the screen (where several items are already selected), check C++/CLI support.
- [Optional] Start Visual Studio and Open Tools->Options under "Projects and Solutions" click on VC++ Directories and add the following to the Executable directories. This is not needed if you use
msconfig\set_build_env.batto set the PATH before you build.
- Move $(PATH) to the bottom as sometimes C:\cygwin\bin is in the $(PATH) which can cause issues with HTCondor's bundled binaries.
- [Optional] Install Python 3.6 64-bit. This is needed to build and/or use the python bindings.
- The default installation directory is buried deep in your home directory. Recommend you install it to C:\Python36 instead.
- Add the following environment variable: PYTHONPATH=C:\Python36;C:\Python36\DLLs;C:\scratch\condor\release_dir\lib\python
- [Optional] Install WiX 3.0 on your windows machine (Depends on Visual Studio). WiX is not needed to build, but it is needed to create the MSI installer.
These instructions for building HTCondor from source all assume the following:
- Your source files live in C:\scratch\condor\src
- Out-of-source builds live in C:\scratch\condor\src-build
- Your release/installation folder is C:\scratch\condor\release_dir
- Open the Developer Command Prompt for VS 2017. Note that using the regular command prompt has incorrect environment variables.
- Checkout origin/master from the git repository.
- From AFS:
git clone /p/condor/repository/CONDOR_SRC
- From Github:
git clone https://github.com/htcondor/htcondor
- From AFS:
- Add the c:\scratch\condor\src\msconfig folder to your PATH.
- [Optional] If you want to use cached externals set the environment variable
CONDOR_BLD_EXTERNAL_STAGEto the PATH of the externals cache. Using cached externals can save a lot of time if you plan to build HTCondor more than once. For example:
- Run cmake from your source folder.
- For in-source builds:
cd C:\scratch\condor\src cmake -G "Visual Studio 15 2017 Win64"
- For out-of-source builds:
mkdir C:\scratch\condor\src-build cd C:\scratch\condor\src-build cmake -G "Visual Studio 15 2017 Win64" C:\scratch\condor\src
- This will create Visual Studio Project and Solution files to build HTCondor. Many options can be passed to cmake, see CondorCmakeBuildOptions for more information. You can also use the cmake-gui to set options.
- For in-source builds:
- Now start the actual build, from whichever folder you ran cmake from:
msbuild /m:4 /p:Configuration=RelWithDebInfo /fl1 ALL_BUILD.vcxproj
- Finally, install your compiled binaries to the release folder. There is a cmake file that will copy the build products to the correct subdirectories of a HTCondor installation. From your source folder, run:
cmake -DBUILD_TYPE=RelWithDebInfo -DCMAKE_INSTALL_PREFIX:PATH=c:\scratch\condor\release_dir -P cmake_install.cmake
Note - If the build fails, remove external and local build folders
Then start over. We don't recover well after a failed build.
Build the tests target in the Condor.sln Solution File. Once built you can run all the batch tests as before.
Note: Building the INSTALL target in the Condor.sln solution file invokes this cmake file. It will copy build results to $(SolutionDir)\release_dir
Making the MSI installer
The WiX programs are used to create the MSI installer. Before you can create the MSI, you must copy build results to a release directory. See above.
To build the MSI, make sure that WiX is in your PATH, then navigate to the release dir and run
etc\WiX\do_wix.bat passing the path to the release dir and the name of the output MSI file as arguments. For example, if your release dir is
c:\scratch\condor\release_dir you would execute
cd c:\scratch\condor\release_dir etc\WiX\do_wix.bat %CD% c:\scratch\condor\Condor-X.Y.Z-winnt-x86.msi
