| Summary | 0013639: Parellel builds of targets in the same CMakeLists.txt sometimes fail |
| Description | I have several libraries in my build that are all declared in the same CMakeLists.txt (by add_library).
Unfortunately, the Visual Studio generator (2010, but I don't think it matters) puts "CMakeFiles\generate.stamp" in the output directory for that CMakeLists.txt. When being build in parallel, these targets sometimes seem to collide, yielding an error like this:
CUSTOMBUILD : CMake error : Cannot restore timestamp <outdir>\CMakeFiles\generate.stamp
AFAICT, there is no documented prohibition on pointing multiple projects' outputs to the same directory. Either this should be fixed, or the restriction should be documented. |
| Steps To Reproduce | Create a CMakeLists.txt with multiple add_library commands. Build with VS2010, with parallel building enabled, on a multicore computer. Observe the failure listed in the description. |
| Additional Information | There would be some work involved in cutting our build config down to something I could submit; please let me know if that is required. |
| Tags | No tags attached. |
