[Mesa-dev] Problem with LLVM on Windows with MSVC

[Shervin Sharifi]

Thank you.
I have compiled llvm with /MDd options, but Mesa doesn't accept that and
asks for /MTd.
So I compiled llvm with /MTd and it worked.
However, I prefer to change Mesa to dynamic option, but I don't know how to
do that. I tried the following, but got another error:

The only thing I found is this in the scons\gallium.py:
    if env['platform'] == 'windows' and msvc:
        # Choose the appropriate MSVC CRT
        # http://msdn.microsoft.com/en-us/library/2kzt1wy3.aspx
        if env['build'] in ('debug', 'checked'):
            env.Append(CCFLAGS = ['/MTd'])
            env.Append(SHCCFLAGS = ['/LDd'])
        else:
            env.Append(CCFLAGS = ['/MT'])
            env.Append(SHCCFLAGS = ['/LD'])

I changed the /MTd to /MDd and compiled. I got the following error, so I'm
not sure if this is the right way of doing it.

src\glsl\ir_constant_expression.cpp(57) : error C2491: 'copysign' :
definition of dllimport function not allowed

Thanks,
    Shervin

P.S. You're right Marius. It was a typo. I missed the i at the end when
copying the command line ("gd" instead of "gdi").
