Extra Hard Mid Boss
Can you successfully build a simple "hello world" application? If that works, go over your linker invocation in your makefile. In particular, the library and object file order matters. GNU ld will only keep symbols from static libraries it thinks are needed, so if the object a.o depends on the library b.a, a.o must appear before b.a on the linker command line.

The missing refs sounds like you're missing the libraries. Maybe they changed the path in the latest arc. Double check the paths for libc, libgcc, and libgcc-Os-4-200.

I did, I don't see any difference, i never used -lgcc-Os-4-200 to compile.

collect2: ld returned 1 exit status
make: *** [Wolfenstein3D.elf] Error 1So it's just as I learned before - if you compile for SH2 (-m2), you NEED to link against that lib. If you compile to SH1, you don't, but you also can't take advantage of the extra SH2 instructions. I used to compile my 32X stuff as SH1 until I learned to link against gcc-Os-4-200.

I wasn't, but adding it makes no difference - still get those errors. I think it's more from using the gcc libc and libgcc than any flags - you use the libc and libgcc, you HAVE to use libgcc-Os-4-200 for SH2.
I use libc and libm from newlib, and libgcc from gcc. On something like the SH2, I don't see using custom libc/libm as necessary. Even on the 68000, using newlib isn't a big deal.

My C++ example, as simple as it is, requires it too.
Code:
-lstdc++ -lc -lgcc -lgcc-Os-4-200 -lnosysThe SH2 build of libgcc simply REQUIRES libgcc-Os-4-200.

I tried -nodefaultlibs and it doesn't change the behavior. The only flag I know of that does is the machine flag... -m1 doesn't require it, and -m2 does. Like I said above, if you use libgcc for the SH2, you have to use the other or you get the link errors I posted previously.

Extra Hard Mid Boss
There is definitely something weird about your setup. GCC automatically links against libgcc, libgcc-Os-4-200 and libc unless you use -nodefaultlibs or -nostdlib. G++ will also automatically link against libstdc++ unless explicitely prevented. Do you have a small example project I could try?

You'll find the archive of examples towards the bottom. You'll want the 32X examples... there is both a C and a C++ example, both of which show the same behavior, with or without -nodefaultlibs. They use -nostdlib to prevent gcc from automatically linking in the "standard" crt0.o, and then the makefile links in libc libgcc libgc-Os-4-200.

Ah - okay. So if you don't need those other libs (or are using minimal replacements), use -nostartfiles. Thanks for pointing that out. It's hard to keep track of all those crazy options, ESPECIALLY the ones for optimization.
