Helping compiling Gens (Sega Emulator)

[sirdeets]

Hello all, I'm trying to build Gens from source, using the instructions from another thread here: http://ubuntuforums.org/archive/index.php/t-28695.html

Specifically, I grabbed the src from CVS using the instructions given in that thread, by typing the following:
cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/gens login
cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/gens co -P GensForLinux

I ran the configure script just fine... however, when I type "make", I eventually get the following:

gcc -DHAVE_CONFIG_H -I. -I. -I../.. -I./gens_core/cpu/68k -I./gens_core/cpu/sh2 -I./gens_core/cpu/z80 -I./gens_core/sound -I./gens_core/mem -I./gens_core/misc -I./gens_core/gfx -I./gens_core/io -I./gens_core/vdp -I./segacd -I./mp3_dec -I./sdllayer -I./util -I./port -I./emulator -I./debug -I./netplay -I./gtkui -I./gtkui/anjuta_widget -I./gtkui/glade -I. -DDATADIR=\"/usr/local/share/gens\" -I/usr/include/SDL -D_REENTRANT -I/usr/include/gtk-2.0 -I/usr/lib/gtk-2.0/include -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/pango-1.0 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -g -O2 -g -O2 -c -o emulator/gens-g_main.o `test -f emulator/g_main.c || echo './'`emulator/g_main.c

Can anyone help me track down what's going wrong? I'd appreciate any help. Thanks!

[sirdeets]

bump... any help would be really appreciated :-\

[chronusdark]

same error perhaps its a bug?

[chronusdark]

got it

you have to do

export CC=/usr/bin/gcc-3.4
./configure
make
make install

got it

you have to do

export CC=/usr/bin/gcc-3.4
./configure
make
make install

Thanks, that seems to work now (though it seems to lack gamepad support).

[sirdeets]

Wow, that was huge. Thanks a lot :smile:

Out of curiosity, how did you know that this was the fix?

As an aside, I can get the emulator to run fine, and can load games to boot. However, the games have no sound. Console output shows:
SDL: Audio timeout - buggy audio driver? (disabled)
audio: Bad file descriptor

Any ideas? Thanks again for the help!

Thanks... I wrote some directions in the linked thread, but they stopped working after I upgraded to Breezy. I guess GCC 4.0 has problems with some software... Thanks for the tip on how to select a GCC version. I never really knew how to do that.
