Has anyone else run into errors rebuilding objects using the Xcode generator? I imagine it would be a bug in xcodebuild, not cmake. We've been using incremental builds, rather than clean builds, for years with cmake on GNU/Linux (make), OSX (Xcode), and Windows (MSVC) and this is the first time I've ever seen this.
One of our C++ unit tests got a bus error on OSX and while debugging it became clear that one of our object files was not rebuilt after a header file had changed (obviously very bad). Looking at the build directory, the object file was definitely NOT rebuilt when it should have been: the object file's time-last-modified was April 29, the object file's ".d" file contained the fully-qualified path to the header file in question, and the time-last-modified on the header file was May 12. The build log shows other object files being rebuilt, but not this one. There's absolutely nothing special about this file: it's just a standard C++ source file and appears in a list of similar C++ files in my CMakeLists.txt file. I've never seen this happen before, has anyone else run into it? This makes me very concerned! $ cmake --version cmake version 3.1.0 $ xcodebuild -version Xcode 6.2 Build version 6C131e $ sw_vers ProductName: Mac OS X ProductVersion: 10.9.5 BuildVersion: 13F1066 -- 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.
