Re: [ggt-devel] Continue about the pygmtl problem.

[Patrick H. <pa...@13...>]

I think that the problem is that the DLL manifest for gmtl.pyd is not being
found by the runtime loader. The PyGMTL build does not embed the manifest in
the DLL when using Visual C++ 8.0. This can be corrected. Build PyGMTL again
using the attached SConstruct file as a replacement for the one in your GMTL
source tree. (I assume that you are using GMTL 0.5.4.) You do not need to
clean your build tree if you still have it. The change I made only modifies
how gmtl.pyd is linked, so only the last step of the build needs to be
performed.

I don't know what the Unicode warning is about, but it seems like a Boost
problem. I don't see any non-ANSI characters in boost/utility/enable_if.hpp
after skimming it. It's too bad that the compiler does not say what line
contains the problematic character(s).
