[Qemu-devel] build problems on SuSE 9.1 w/CVS from 2004/05/31

[Kyle Hayes <kyle@silverbeach.net>]

I'm building with CVS from today.  My system is a P4 w/SuSE 9.1 installed, 
2.6.4 kernel.

I see two problems:

1) when I run configure, I apparently cannot build anything that needs 
static SDL:

linux:~/qemu/qemu # ./configure --prefix=/usr/local --enable-slirp

BIOS directory    /usr/local/share/qemu

static build      no
SDL support       yes
SDL static link   no
mingw32 support   no
WARNING: cannot compile statically with SDL - qemu-fast won't have a 
graphical output

I've installed all the SDL packages that SuSE 9.1 has.  Both sdl-config and 
aalib-config report that there are static libs:

linux:~/qemu/qemu # aalib-config --static-libs
-L/usr/lib -Wl,-rpath,/usr/lib -laa -lm -L/usr/X11R6/lib -lX11 -lgpm 
-lslang

linux:~/qemu/qemu # sdl-config --static-libs
-L/usr/lib -Wl,-rpath,/usr/lib -lSDL -lpthread -lm -ldl -lasound 
-L/usr/X11R6/lib -lX11 -lXext -laa

Under Gentoo, I had a problem with libasound.a missing.  However, under 
SuSE 9.1, it is there:

linux:~/qemu/qemu # locate libasound
/usr/lib/libasound.a
/usr/lib/libasound.la
/usr/lib/libasound.so
/usr/lib/libasound.so.2
/usr/lib/libasound.so.2.0.0

I thought I would try to build anyway.  I don't usually use qemu-fast, so 
this wasn't really a problem.  However, I find this:

linux:~/qemu/qemu # make

I've done a grep -r in /usr/include and nothing in there has "SO_BSDCOMPAT" 
set.  I've searched the mailing list archive for this and do not see 
anything about it.  

If I comment that one line (line 579 in syscall.c) out, then the build 
succeeds.  I have not had a chance to use it yet.  I rather suspect that 
this will break something somewhere.  I don't use the user-mode of QEMU 
either, but still....

Best,
Kyle
