The following issue has been SUBMITTED. ====================================================================== http://www.cmake.org/Bug/view.php?id=15596 ====================================================================== Reported By: Reid Kleckner Assigned To: ====================================================================== Project: CMake Issue ID: 15596 Category: (No Category) Reproducibility: have not tried Severity: minor Priority: normal Status: new ====================================================================== Date Submitted: 2015-05-29 13:47 EDT Last Modified: 2015-05-29 13:47 EDT ====================================================================== Summary: CMakeClDeps.cmake doesn't work if CC contains arguments Description: I am attempting to do a 32-bit self-host of clang on Windows with a 64-bit clang-cl binary. By default, the 64-bit binary generates 64-bit code, so I need to pass the -m32 flag to override that. I figured the most robust way to do this is something like setting CC="clang-cl -m32" and running cmake.
This *almost* worked, but CMakeCLDeps.cmake runs CMAKE_C_COMPILER without the flags present in CC, and the link failed. It's regex then matched the error message from LINK, and I got this in rules.ninja: msvc_deps_prefix = LINK : error LNK2001: CMakeClDeps.cmake doesn't actually need to do a link, so one easy workaround would be to add /c to command line there. That's probably a good tweak in general, since it saves an invocation of link.exe, and cuts down on moving parts. :) Aside from the workaround, is there a more canonical way that CMakeClDeps should be invoking the compiler that includes flags from the CC env var? ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2015-05-29 13:47 Reid Kleckner New Issue ====================================================================== -- 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.
