Trouble making on Linux PowerPC

[ppcluddite]

I'm having trouble getting Sheepshaver working on Debian Wheezy PowerPC. I installed the dependencies libx11-dev, libgtk2.0-dev, libesd0-dev, and libsdl1.2-dev, then did:

cd macemu/SheepShaver
make links
cd src/Unix
NO_CONFIGURE=1 ./autogen.sh
./configure --enable-sdl-video --enable-sdl-audio --disable-vosf
make

but it failed with Error 1:

https://gist.github.com/ppcluddite/7308026

I then succeeded in getting it to build with an altered sheepthreads.c file found in this post:

http://www.emaculation.com/forum/viewtopic.php?f=20&t=6553&start=25#p43895

However, when I start up SheepShaver, the terminal only outputs this:

dan@powerbook:~/Development/macemu/SheepShaver/src/Unix$ ./SheepShaver
SheepShaver V2.4 by Christian Bauer and Mar"c" Hellwig

No preference window comes up or anything. I also added vm.mmap_min_addr = 0 to /etc/sysctl.conf. Here are the configure and make outputs to the second build:

There are warnings in it about prefs_editor_gtk, but I don't know exactly what they mean. This is where I'm stuck.

I tried to debug a SheepShaver built with the updated sheepthreads.c Quitting SheepShaver and stepping into it results in:

Single stepping until exit from function usleep,
which has no line number information.
fastlock_acquire (lock=0x1011e330) at Linux/sheepthreads.c:211
211 while (test_and_set(&lock->spinlock, 1))
(gdb) step
212 usleep(0);

It seems to be stuck in this loop.

Commenting out this in sheepthreads.c:
static void fastlock_acquire(struct fastlock *lock)
{
MEMORY_BARRIER();
//while (test_and_set(&lock->spinlock, 1))
// usleep(0);
}

makes the GUI appear.

Next error is: Cannot map usable RAM area. Try to decrease the MacOS RAM size.

Hi,

I commented out those two lines like you said and got the GUI to appear, too. When I clicked Browse to navigate to the rom file, though, it quit. The error message was this:

**
GLib-GIO:ERROR:/build/glib2.0-OdhN7C/glib2.0-2.36.4/./gio/gdbusconnection.c:1627:g_dbus_connection_send_message_unlocked: CONNECTION_ENSURE_LOCK: GDBusConnection object lock is not locked
Aborted

So then I went back and hand-typed in the path to the rom and clicked Start, and I got the disk with the question mark window. I believe here is where a .sheepshaver_prefs file is created. Anyway, I killed the process and restarted, and since I got the above crash when trying to create a disk image, I copied one created in SheepShaver on OS X and added its path manually to .sheepshaver_prefs (disk /home/dan/MyDisk.dsk). Started SheepShaver again. Now I get to the welcome screen, but it freezes most of the time when the extensions are loading. A couple of times I disabled extensions and got to a desktop, but it froze whenever I clicked on a menu.

Here are some error messages I got when it froze during extensions loading:

So close yet so far. I never did see your error, "Cannot map usable RAM area. Try to decrease the MacOS RAM size."

Hi Christian wonderful is use your program because make me remember the wonderful Amiga time Shapeshifter rulez.
So: On PowerPc 5020 im facing issue with Shapeshever
Cannot map usable RAM area. Try to decrease the MacOS RAM size.
i been try many configure and nothing change.
I think this issue is becasue the ram mapping, i can test with direct but i dont find any info how to configure it.

Thanks!
