New subject: Mingw 3.4.2 char_traits.hpp patch fixes shmem-0.93 build for winxp

14 Jun 2006

      to interested parties:

i did some additional searching today and managed to find out that
there is a bug in mingw's c++ include directory.

to get shmem compiled for winxp using mingw,

go into your equivalent to "/C/MinGW/include/c++/3.4.2/bits"

open "char_traits.hpp" and comment out lines 309 and 311.

The area, after commenting, should look like this:

309:   //#if defined (_GLIBCXX_USE_WCHAR_T)
310:   typedef wstreampos 	pos_type;
311:   typedef mbstate_t 	state_type;
312:   //#endif

the define statement conflicts with a similar define statement that
takes places at the begining of this template type's definition.

after completing this simple patch, run the build script for mingw in
the shmem 0.93 and try out the test programs, they should work at this
point.

the semi-notorious, "fixes error: no type named `pos_type' in `struct
std::char_traits<wchar_t>'" error is gone.

thanks to those parties that were looking into this issue and i hope
this proves helpful for someone out there.
