Re: [Qemu-devel] compiling on Mac OS X

[David E . Still]

Here's the solution I posted on Tuesday regarding this and a couple of 
other OS X build issues:
---
I'm still having build issues with the latest cvs builds.  I've been 
able to resolve them all, but they should probably be fixed at the 
source:

1. In OS X, <sys/mman.h> does not include <sys/types.h>.  I was able to 
get it to compile by adding #include <sys/types.h> in front of #include 
<sys/mann.h> in exec.c, but it should probably be added to each file 
where sys/mman.h is called.  Perhaps with the following (sorry, I'm 
feeling too lazy to create a patch file :) ):

#ifdef __APPLE__
#include <sys/types.h>
#endif
#include <sys/mman.h>

2. A minor problem with the sparc guest build.  In Mac OS X, the _sqrtf 
function is in lmx, not lm.  So a minor change to the Makefile.target 
file:

--- qemu/Makefile.target        Mon Oct  4 14:23:09 2004
+++ qemu-cvs-20041011/Makefile.target   Mon Oct 11 12:05:10 2004

+ifeq ($(CONFIG_DARWIN),yes)
+LIBS+=-lmx
+endif

 # profiling code
 ifdef TARGET_GPROF

and sparc target will build.  I presume that it works; I haven't tested 
it.

3. This isn't really a build issue, but I thought I'd include it.  
Since OS X doesn't use OSS for audio, why not have SDL built by default 
on OS X?  Try this patch:

--- qemu/oss.c  Sat Oct  9 10:20:54 2004
+++ qemu-cvs-20041011/oss.c     Mon Oct 11 11:37:51 2004
@@ -30,7 +30,7 @@

 /* TODO: Graceful error handling */

-#if defined(_WIN32)
+#if defined(_WIN32) || defined(__APPLE__)
 #define USE_SDL_AUDIO
 #endif

That's all I have for now, other than latest cvs appears to be broken. 
:(  Everything builds the same between yesterday (which I created the 
patches) and today, but today's qemu just pulls up a blank screen, or 
occaissionally some garbage.  Not sure how to test that further.  And I 
may be making some incorrect assumptions, such as the __APPLE__ flag 
indicating an OS X environment. [Ed: Tested, this flag does work.]  
Also, I have yet to get Win98 guest to produce any sound, even with the 
above patch.  Still haven't tried Malc's patch, though.  Perhaps later.
