Yes, this is the right place to report it, especially since this is
recent development. For reference, support for this toolset was added
in a topic merged here:
Merge topic 'vs-clang-cl'
https://cmake.org/gitweb?p=cmake.git;a=commit;h=612a8b3b
based on discussion in this thread:
[PATCH SET] Support of Clang/C2 compiler.
http://thread.gmane.org/gmane.comp.programming.tools.cmake.devel/15902
I have found some changes that seems to be necessary to be able to
debug, here are the changes I have found:
1) DebugInformationFormat should be set FullDebug, AdditionalOptions
MUST BE removed and optimizations must be disabled
<ClCompile>
... REMOVE AdditionalOptions ...
<DebugInformationFormat>FullDebug</DebugInformationFormat>
...
<Optimization>Disabled</Optimization>
<OmitFramePointers>false</OmitFramePointers>
</ClCompile>
2)GenerateDebugInformation must be set to true and ProgramDataBaseFile
must be empty because clang doesn't use pdb for now
<Link>
...
<GenerateDebugInformation>true</GenerateDebugInformation>
...
<ProgramDataBaseFile>
</ProgramDataBaseFile>
</Link>
Mariusz, please take a look at this.
See also this hack:
VS: Fix VS 2015 .vcxproj debug setting for older toolsets
https://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=dc422d27
Basically we need to have a different flag table for each possible
toolset. Also it looks like additional special handling may be
needed for PDBs and perhaps other limitations of the Clang/C2
toolchain.
Thanks,
-Brad
Just a small update about what I wrote regarding AdditionalOptions, I
found that it's not necessary to remove the whole line but only the
-gline-tables-only parameter.
