I dont know if this is the right place to post this question. I've tried already on the wineasio sourceforge forum, but no response. I think this particular question is something wine experts would know about since it looks to be borrowed code from wine. Most of the wineasio folks seem to be linux focused only.
In any case, I'm trying to compile the latest wineasio 0.90 on OSX 10.6.8. I have already built wine 1.5.4.
I get some errors immediately related to some ELF assembler code injection that I believe has to do with working around COM. Here is the error and below that is the code I think causing the problem to build. Does anyone have any ideas what I would need to tweak to get past this particular problem?
Code:
gcc -c -I. -I/usr/include -I/Users/sjs/wine/wine-1.5.4/include -I/Users/sjs/wine/wine-1.5.4/include/wine -I/Users/sjs/wine/wine-1.5.4/include/wine/windows -m32 -g -O2 -D__WINESRC__ -D_REENTRANT -fPIC -Wall -pipe -fno-strict-aliasing -Wdeclaration-after-statement -Wwrite-strings -Wpointer-arith -o asio.o asio.c
{standard input}:36:Unknown pseudo-op: .type
{standard input}:36:Rest of line ignored. 1st junk character valued 95 (_).

{standard input}:43:Unknown pseudo-op: .cfi_endproc
{standard input}:44:Unknown pseudo-op: .previous
{standard input}:48:Unknown pseudo-op: .type
I'm pretty sure this is the code causing the problem.
Code:
/* ASIO drivers (breaking the COM specification) use the Microsoft variety of
* thiscall calling convention which gcc is unable to produce. These macros
* add an extra layer to fixup the registers. Borrowed from config.h and the
* wine source code.
