The following issue has been SUBMITTED. ====================================================================== http://www.cmake.org/Bug/view.php?id=15368 ====================================================================== Reported By: peitschie Assigned To: ====================================================================== Project: CMake Issue ID: 15368 Category: CMake Reproducibility: always Severity: minor Priority: normal Status: new ====================================================================== Date Submitted: 2015-01-23 01:18 EST Last Modified: 2015-01-23 01:18 EST ====================================================================== Summary: ExternalProject's BUILD_ALWAYS flag doesn't clear any existing build stamp file Description: Setting the BUILD_ALWAYS flag on an external project should cause the build step to always trigger. This was new in 3.1 from what I can see. Unfortunately, it appears to do this by making the *next* stamp file created symbolic (see https://github.com/Kitware/CMake/blob/master/Modules/ExternalProject.cmake#L1457). This means that until the existing stamp file is deleted, or something else causes a rebuild to occur, BUILD_ALWAYS has no effect
Steps to Reproduce: 1. Create a CMake file with an external project, with BUILD_ALWAYS set to 0 2. Build the external project 3. Change the BUILD_ALWAYS flag to 1 4. Attempt to rebuild the external project, and note how the build step is never executed. ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2015-01-23 01:18 peitschie New Issue ====================================================================== -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
