Testing the clang-cl integratio with VS2010

Clang Frontend
#1

HI, I'm trying to do some tests with the clang-cl build found at http://llvm.org/builds/ with the VisualStudio 2010 compiler, and I get this error for any project or single file I tested.

1>C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\Platforms\Win32\Microsoft.Cpp.Win32.Targets(153,5): error MSB6006: "CL.exe" exited with code -1073741515.

Any clue on whats going on? I tried looking on the Bugzilla or google but found nothing.

This is 0xc0000135, aka STATUS_DLL_NOT_FOUND.
http://msdn.microsoft.com/en-us/library/cc704588.aspx

clang-cl as distributed appears to have a few dll deps:

$ dumpbin /dependents C:/Program\ Files\ (x86)/LLVM\ 3.4.svn/msbuild-bin/cl.exe

KERNEL32.dll
SHELL32.dll
ADVAPI32.dll
MSVCP110.dll
MSVCR110.dll
dbghelp.dll

Looks like we have a dependence on the 2012 C and C++ runtimes. You can probably work around this by installing the VC++ 2012 redistributable bits from http://www.microsoft.com/en-us/download/details.aspx?id=30679 I think our users so far have had VS2012 installed, so nobody has noticed this.

We should eliminate that dependence with static linking or dll redistribution.

Hello,

Could you try this (unofficial) build and let me know if it works?

  http://clang.org/builds/clang-3.4a-win32.exe

I think the /MT change is good to upstream if so.

Alp.

Thanks Reid, that worked fine, but sadly clang-cl is not working for my code base, I get this errors even if I don’t use RTTI.

CL : error : cannot mangle RTTI descriptors for type ‘CPropTypeDirect’ yet
CL : error : cannot mangle the name of type ‘CPropTypeDirect’ into RTTI descriptors yet.

Try "-GR-" to disable it.
Indeed, RTTI is not yet supported.

I tested and works fine, but I already installed the "recommended" run-times, so I can confirm if this would work without them.

About the RTTI problem I allready disabled RRTI, in fact this "command line options" work;

/I"../../../../dist/krm/inc/" /I"../../../../dist/3rdParty/" /I"../../../../dist/3rdParty/Glew/Include/" /I"../../../../krm/inc/" /I"../../../../krm/src/" /Zi /nologo /W0 /WX- /Od /Ob0 /Oy- /D "KRMCFG_GPU_OPENGL" /D "KRMCFG_MODE_DEBUG" /D "KRMCFG_CPU_X86" /D "KRMCFG_CPU_FLOAT" /D "KRMCFG_PLATFORM_WIN" /D "KRMCFG_PLATFORM_VERSION_WIN_32" /D "_UNICODE" /D "UNICODE" /GF /Gm /EHa /RTC1 /MDd /GS /arch:SSE2 /fp:fast /Zc:wchar_t /Zc:forScope /GR- /Fp"..\..\..\..\tmp\krm\code\sal\Win32_OGL_Debug\sal.pch" /Fa"..\..\..\..\tmp\krm\code\sal\Win32_OGL_Debug\" /Fo"..\..\..\..\tmp\krm\code\sal\Win32_OGL_Debug\\" /Fd"..\..\..\..\dist\krm\lib\sal\Win32_OGL_Debug\/sal.pdb" /Gd /wd"4996" /wd"4345" /analyze- /errorReport:queue

But if I switch to "final" configuration with this settings it fails:

/I"../../../../dist/krm/inc/" /I"../../../../dist/3rdParty/" /I"../../../../dist/3rdParty/Glew/Include/" /I"../../../../krm/inc/" /I"../../../../krm/src/" /Zi /nologo /W4 /WX- /Ox /Ob2 /Ot /Oy- /D "KRMCFG_GPU_OPENGL" /D "KRMCFG_MODE_FINAL" /D "KRMCFG_CPU_X86" /D "KRMCFG_CPU_FLOAT" /D "KRMCFG_PLATFORM_WIN" /D "KRMCFG_PLATFORM_VERSION_WIN_32" /D "_UNICODE" /D "UNICODE" /GF /Gm- /EHa /MD /GS /arch:SSE2 /fp:fast /Zc:wchar_t /Zc:forScope /GR- /Fp"..\..\..\..\tmp\krm\code\sal\Win32_OGL_Final\sal.pch" /Fa"..\..\..\..\tmp\krm\code\sal\Win32_OGL_Final\" /Fo"..\..\..\..\tmp\krm\code\sal\Win32_OGL_Final\\" /Fd"..\..\..\..\dist\krm\lib\sal\Win32_OGL_Final\/sal.pdb" /Gd /wd"4996" /wd"4345" /analyze- /errorReport:queue

SO I think there is some interactio with the optimization settings I enabled....

Also as a side note the /GT parameter (Enable fiber safe optimizations) fails.

See 17403 – VS wrapper: "cannot mangle RTTI descriptors for type 'error_category'"
