Re: [CMake] ExternalProject git update problem

[Sascha Zelzer]

Hi Jc,

yes, I did. Actually "origin/master" for most of our dartclients.

Thanks,

Sascha

Hi Sasha,

Out of curiosity, what's the value of PROJ_GIT_BRANCH ?

Did you specify <REMOTE_NAME>/<BRANCH_NAME>. For example: "master/origin"

    Hi,

    we are using the ExternalProject module from CMake 2.8.4 and are
    observing a strange git update problem on Windows 7 when running a
    CTest script (using the new-style ctest_build, etc. commands).

    Our ExternalProject_Add call essentially looks like this:

    ExternalProject_Add(${proj}
       GIT_REPOSITORY "${PROJ_GIT_REPOSITORY}"
       GIT_TAG "${PROJ_GIT_BRANCH}"
       BINARY_DIR ${PROJ_BINARY_DIR}
       INSTALL_COMMAND ""
       CMAKE_GENERATOR ${gen}
       CMAKE_ARGS
         ${ep_common_args}
         -DBUILD_SHARED_LIBS:BOOL=ON
       DEPENDS
         ${proj_DEPENDENCIES}
       )


    In the CTest script, when calling:

    set(CTEST_BUILD_TARGET ${proj})
    ctest_build(BUILD "${build_dir}" APPEND)

    a message gets printed on the console (in extra verbose mode),
    telling that it runs the update step for the external project, but
    it actually does not update the git repository. Strangely, I was
    able to "fix" this problem by playing around in
    ExternalProject.cmake (from CMake 2.8.4) and adding the following
    line at line 894:

    set(comment "${comment}, command: ${command}")

    It then does not print the comment anymore, but rather prints the
    used git command line arguments (again in extra verbose mode) and
    actually updates the repository.

    Does anybody know what the reason for this strange behavior could be?

    Thanks,

    Sascha
