[Mesa3d-dev] mesa 3.2/win32+3dfx with optimizations link-error (?!?)

[Alessandro P. <al...@ti...>]

Hi all.
I'm having some problems with 3dnow and MMX optimized code compiling the 
Mesa3.2 for Win32 using 3dfx-Glide driver.
I use MS-VC 6.0, NASM 0.98 and Glide SDK 2.x.
The problem is: the code is compiled and linked successfully in 
opengl32.dll *only if* i do not set USE_X86_ASM nor USE_3DNOW_ASM nor 
USE_MMX_ASM, which i do adding /DUSE_xxx_ASM swtiches in the $(CPPOPTS) 
field of (mesadir)\WIN32\RULES\LIB.FXMESA and 
(mesadir)\WIN32\RULES\LIB.FXMESA32 .

Enabling these switches (which make optimized routines becoming operative) 
cause code to be compiled successfully but resulting in a linked error from 
NASM during opengl32.dll creation. Also, as far as i see in makefile.fx 
file in (mesadir)\src, the file src\fx\x86\fx_3dnow_fastpath.S is NOT 
compiled 'cos it is missing in both lib.fxmesa and lib.fxmesa32.

The error i obtain is specifically this:

.\Release\fxmesa32\OpenGL32.dll ...
NMAKE : fatal error U1077: 'E:\PROGRA~1\MICROS~2\VC98\BIN\link.exe' : 
return code '0x460'
Stop.
NMAKE : fatal error U1077: '"E:\PROGRAMMI\MICROSOFT VISUAL 
STUDIO\VC98\BIN\NMAKE.exe"' : return code '0x2'
Stop.
NMAKE : fatal error U1077: '"E:\PROGRAMMI\MICROSOFT VISUAL 
STUDIO\VC98\BIN\NMAKE.exe"' : return code '0x2'
Stop.

I found it happens IF AND ONLY IF the gl_init_xxx_asm_transforms() (where 
xxx can assume values of x86, 3dnow, mmx) function is compiled.

Is this a known problem ? What can I do ?
Thank you in advance,
TXM
