Hi,
I have been trying to build Mesa-7.1 with mingw. Probably should have
tried with a RC, sorry.
Just two little things that I find.
1. Mesa-7.1/src/mesa/Makefile.mgw
This file references the CORE_SOURCES variable which no longer exists.
I used MESA_SOURCES and GLAPI_SOURCES to get it to work.
Patch Makefile.mgw.7.1.patch attached.
2. Mesa-7.1/src/mesa/main/imports.c
The _mesa_ffs function specifically tries to use the glibc inbuilt
function rather than the code written here. Unfortunately this no
longer compiles on my up to date cygwin-mingw system because the symbol
_ffs is not found at link. I went back and tried to rebuild a
previously successful build of 7.0.1 and that fails at linking too. I
went looking to see if I could find record of a change in mingw but
haven't found it yet. Even so I removed the specific use of this
function for MINGW to get it working (I notice that the compilation step
also warns that the function is not declared.)
Patch mesa-main-imports-7.1.patch attached.
With these two little patches mesa builds fine (although not GLU, but I
didn't investigate).
Shane.
