The following issue has been SUBMITTED. ====================================================================== http://www.cmake.org/Bug/view.php?id=14706 ====================================================================== Reported By: Luis Vega Assigned To: ====================================================================== Project: CMake Issue ID: 14706 Category: CMake Reproducibility: always Severity: major Priority: normal Status: new ====================================================================== Date Submitted: 2014-01-17 15:11 EST Last Modified: 2014-01-17 15:11 EST ====================================================================== Summary: Sources compiled multiple times when building with make, multiple jobs, and targets with common dependencies Description: A source file will be compiled multiple times when the following combination of conditions are met: -Using gnu make to build the project. -Two targets that have a common dependency are specified to the make command. -Using multiple jobs.
If targets "foo" and "bar" depend on target "dep" and a build command is issued as: make -j foo bar Then "dep" sources will be compiled twice. Steps to Reproduce: Create library target "dep" Create executable target "foo" and link to "dep" Create executable target "bar" and link to "dep" Create gnu makefiles with cmake Issue build command as: make -j foo bar Output will show that each "dep" source was compiled twice (once per target that depends on "dep"). ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2014-01-17 15:11 Luis Vega New Issue 2014-01-17 15:11 Luis Vega File Added: example.tar.gz ====================================================================== -- 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
