Hello CMake Developers! Looks like I found interesting bug in CMake: - ADD_CUSTOM_TARGET() always creates Makefile rule for ADD_CUSTOM_COMMAND(). - As result build simetimes failed if specified -jN for make.
Please find attached simple project which reproduce the problem. > [ 12%] Generate /home/kaa/cmake_add_custom_command-target/build/config > [ 25%] Generate /home/kaa/cmake_add_custom_command-target/build/config > [ 37%] Generate /home/kaa/cmake_add_custom_command-target/build/config > [ 50%] Generate /home/kaa/cmake_add_custom_command-target/build/config > [ 62%] Generate /home/kaa/cmake_add_custom_command-target/build/config > [ 75%] Generate /home/kaa/cmake_add_custom_command-target/build/config > [ 87%] Generate /home/kaa/cmake_add_custom_command-target/build/config > [100%] Generate /home/kaa/cmake_add_custom_command-target/build/config > CMake Error at /home/kaa/cmake_add_custom_command-target/cmake/config.cmake:3 (CONFIGURE_FILE): > CONFIGURE_FILE Problem configuring file > > make[2]: *** [CMakeFiles/config2.dir/build.make:61: config] Error 1 > make[2]: *** Deleting file 'config' > CMake Error at /home/kaa/cmake_add_custom_command-target/cmake/config.cmake:3 (CONFIGURE_FILE): > CONFIGURE_FILE Problem configuring file > > make[2]: *** [CMakeFiles/config5.dir/build.make:61: config] Error 1 > make[2]: *** Deleting file 'config' > make[1]: *** [CMakeFiles/Makefile2:216: CMakeFiles/config5.dir/all] Error 2 > make[1]: *** Waiting for unfinished jobs.... > make[1]: *** [CMakeFiles/Makefile2:253: CMakeFiles/config2.dir/all] Error 2 > [100%] Built target config1 > [100%] Built target config4 > [100%] Built target config7 > [100%] Built target config6 > CMake Error at /home/kaa/cmake_add_custom_command-target/cmake/config.cmake:3 (CONFIGURE_FILE): > CONFIGURE_FILE Problem configuring file > > CMake Error at /home/kaa/cmake_add_custom_command-target/cmake/config.cmake:3 (CONFIGURE_FILE): > CONFIGURE_FILE Problem configuring file > > make[2]: *** [CMakeFiles/config0.dir/build.make:61: config] Error 1 > make[2]: *** Deleting file 'config' > make[1]: *** [CMakeFiles/Makefile2:142: CMakeFiles/config0.dir/all] Error 2 > make[2]: *** [CMakeFiles/config3.dir/build.make:61: config] Error 1 > make[1]: *** [CMakeFiles/Makefile2:327: CMakeFiles/config3.dir/all] Error 2 > make: *** [Makefile:84: all] Error 2 -- Best regards, Oleh Kravchenko
