| Summary | 0015427: Xcode generation omits CXX flags for linking | ||||||||
| Description | If I set CXXFLAGS (env var) or CMAKE_CXX_FLAGS, the resulting Xcode project does not contain those flags when linking C++ binaries, but a resulting Makefile does. This can result in link errors when building with Xcode which one does not see when building with Makefiles. | ||||||||
| Steps To Reproduce | Using the attached project, build using Makefiles and it works fine. Build with Xcode and one gets link errors about unresolved symbols from the standard c++ library. Notice how the -stdlib=libstdc++ flag is missing from the link command under Xcode. | ||||||||

The inconsistency is bad for sure, but there are complier flags that the linker does not support. If compiler flags always get passed to the linker, that could be a problem... |

Re 0015427:0038136: We're talking about passing CMAKE_<LANG>_FLAGS to the <LANG> compiler front-end when using it to drive the linker. The front-end knows which options affect how it invokes the linker. This is already done for other generators and is simply missing for Xcode, according to this report. |
