The following issue has been SUBMITTED. ====================================================================== http://www.cmake.org/Bug/view.php?id=15754 ====================================================================== Reported By: Johannes Asal Assigned To: ====================================================================== Project: CMake Issue ID: 15754 Category: CMake Reproducibility: always Severity: major Priority: normal Status: new ====================================================================== Date Submitted: 2015-09-21 10:54 EDT Last Modified: 2015-09-21 10:54 EDT ====================================================================== Summary: Visual Studio incremental build not working properly when target names start with a capital letter Description: When using a target name starting with a capital letter (e.g. Mylibrary) in add_library (and probably also add_executable), GCC toolchains build fine but Visual Studio (tested with 2010 specifically) refuses to compile new .cpp files in the first incremental build after adding them to the CMakeLists.txt. However, it correctly detects that the CMakeLists.txt has changed and reconfigures accordingly. The second incremental build compiles the added files, which makes it even more strange. Please note that the bug occurs only when building via the CMake command line interface (cmake.exe --build). Building from within Visual Studio works always which is why I think it must be a problem with CMake.
Steps to Reproduce: Install Visual Studio 2010. Unzip the attached ZIP file. Open a command line in the /build subfolder and call cmake -G"Visual Studio 10" .. Then do a cmake --build . Watch how test1.cpp is compiled properly. Then open CMakeLists.txt and uncomment the line with test2.cpp. Do an incremental build by calling cmake --build . The change of CMakeLists.txt is detected but test2.cpp is NOT COMPILED! Do a second incremental build cmake --build . Now test2.cpp is compiled. Delete the bugreport folder and extract it again from the ZIP file to return to the initial state. Open the CMakeLists.txt and rename the 'Notworking' target name in add_library to 'working'. Repeat all steps above and you will see that test2.cpp is compiled in the first incremental build already, as one would expect. I tested a lot of combinations and it seems that the capital letter in front seems to be the source of the problem. ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2015-09-21 10:54 Johannes Asal New Issue 2015-09-21 10:54 Johannes Asal File Added: bugreport.zip ====================================================================== -- 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.
