Arch Linux User Repository

@VorpalWay - Thanks for that; I installed linux-mainline (kernel version 6.6rc4-1 at time of writing) and SheepShaver is back to working so far.

@Stormrvr With respect to the allocation failure: https://bugs.archlinux.org/task/79656

Running kernel 6.5.4-arch2-1 - with sysctl vm.mmap_min_addr=0 I also get: ERROR: Cannot map Low Memory Globals: Cannot allocate memory.

As of kernel 6.5.2-arch1-1, it seems like sysctl vm.mmap_min_addr=0 is no longer enough to make SheepShaver work, I keep getting: ERROR: Cannot map Low Memory Globals: Cannot allocate memory.

So I figured out the issue:

checking floating point format... configure: error: Unknown floating point format

I needed to add options=(!lto) to the PKGBUILD.

Unfortunately it still fails to build later on, and I needed to also add -Wno-error=format-security to CXXFLAGS. -Werror=format-security is included by default in Arch's standard makepkg.conf.

So those two changes are needed.

Seems if makepkg is configured for parallel compilation then the build can get ahead of itself creating the obj directory. The symptoms are early error output like "Fatal error: can't create obj/main.o: No such file or directory" (as the directory doesn't exist yet), but the build keeps running for some time and later there is more cryptic output of "cc1plus: note: destination object is likely at address zero".

The makefiles were probably never designed with parallel builds in mind, so suggest perhaps changing the build command to make -j1 in the PKGBUILD. Have confirmed this solves the parallel build issue (running makepkg twice also seems to solve it, lol!)

Also, FWIW, it seems like development has moved from the cebix fork to https://github.com/kanjitalk755/macemu (semi-officially, there's a link in the cebix repo's README). That version seems to build fine from this PKGBUILD as well (although it still has the parallel compilation issue.)

Thanks for packaging SheepShaver for Arch users! :)

having the same configure error as @VorpalWay.

• There is a missing makedepends on git
• I'm also getting the following configure error:

checking floating point format... configure: error: Unknown floating point format

Which is quite odd, for a native (non-cross compiling) build on x86-64.

Also: I cannot reproduce this issue when configuring sheepshaver directly (outside of makepkg)

@hazelnot Thanks for the comment. It looks like this is caused by the CFLAGS '-Werror=format-security' As a workaround, if you remove it from your makepkg.conf, it should work again I'll try to patch it to make it work again.

I'm getting a massive error... thing. Not sure what exactly is failing here:
