The following issue has been SUBMITTED. ====================================================================== http://public.kitware.com/Bug/view.php?id=13572 ====================================================================== Reported By: Craig Scott Assigned To: ====================================================================== Project: CMake Issue ID: 13572 Category: CMake Reproducibility: sometimes Severity: minor Priority: normal Status: new ====================================================================== Date Submitted: 2012-10-04 19:51 EDT Last Modified: 2012-10-04 19:51 EDT ====================================================================== Summary: Automoc can list moc_*.cpp files twice in ..._automoc.cpp Description: If you include the C++ headers in the source files for add_executable() or add_library, I've encountered situations where CMake's automoc support then creates duplicate entries in the (target)_automoc.cpp file it creates. It is as though it identifies the moc_(sourcefile).cpp that it needs from the .cpp files in the source file list, but then finds the same set of moc_(sourcefile).cpp files again when it processes the .h files in the source file list. The result is that the build fails with the compiler complaining about redefinition of whatever the moc_(sourcefile).cpp files provide.
Steps to Reproduce: The problem isn't always reproduceable, but once it does occur, it seems that it keeps occurring. I've not found any way to reliably trigger or not trigger the issue, unfortunately. I've had cases where I've been building with the headers included in the source list for months. Then I change something and I start getting the duplicate problem. Today, it seems I can omit the headers from the source file list and that seems to work. Not sure if that's a solution in general, but it would seem that headers should be allowed to be included in the source file list (I believe this was actually necessary for some earlier versions of CMake and using some combination of features needed for Qt support). Additional Information: Seen with CMake 2.8.8 and 2.8.9. ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2012-10-04 19:51 Craig Scott New Issue ====================================================================== -- Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://public.kitware.com/cgi-bin/mailman/listinfo/cmake-developers
