Re: [cmake-developers] CMake identifies MacOSX10.7-Xcode43-ub as GNU, but it runs clang.

I've reverted my change to the machine-specific dashboard script. Since Tests/CMakeLists.txt is still processed by the older CMake used to run the dashboard it still detects GNU as the compiler id and activates this test. Then the test fails because it is hard-coded to support only GNU and not Clang or AppleClang. -Brad -- 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.

At least that is what is used for the identification step, which is why it identifies as GNU. Ugh. That Xcode selects a different compiler when the project file sets SDKROOT than when it does not. The compiler id step runs very early so Darwin.cmake has not been loaded to set CMAKE_OSX_SYSROOT. When that is later used then the actual generated project files get SDKROOT and Xcode changes the compiler. For the compiler id step Xcode chooses com.apple.compilers.llvmgcc42 but the build uses com.apple.compilers.llvm.clang.1_0.compiler. It looks like in this case users will have to tell Xcode what tool to use up front using the CMake generator toolset feature (cmake -T). I think this is acceptable because it only affects old Xcode versions. Otherwise we will need a much more complicated compiler id bootstrap process :( I've updated the dashboard script on the build in question to specify the clang compiler explicitly. Please drop the non-APPLE condition for the test to see if it works now. -Brad -- 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.

[cmake-developers] CMake identifies MacOSX10.7-Xcode43-ub as GNU, but it runs clang.
Hi, This causes the failure of the WriteCompilerDetectionHeader test: http://open.cdash.org/testDetails.php?test=250378767build=3306874 Though the misidentification has been the case since before that refactoring: http://open.cdash.org/testDetails.php?test=247853583build=3293163 Could this be because it is old clang which did not define __clang__? Apart from the misidentification, I don't understand how the WriteCompilerDetectionHeader test could have a different result than the compiler identification code. It should be checking the same defines in the same order, and it should arrive at the same incorrect conclusion that the compiler is GNU. And ideas?

At least that is what is used for the identification step, which is why it identifies as GNU. After the identification step (when building), clang is used, which is why my test fails. I conditionalized the test execution to exclude APPLE, which is fine for now. It's the same condition in GNU-CXX.cmake, and I introduced it exactly for this reason of excluding platforms from these features from platforms that cause problems until the features themselves are in.
