I'm mainly using the codesourcery ones nowadays (4.4). Nevertheless, does it help if you remove the abi=apcs-gnu line in src/Makeconf.arm?
That causes it to fail just as early with a different message. I'll try with 4.4 and get back to the list on results, thanks.
Ok, thanks.
- Failure to build L4Re due to linker error
The symbol "__stack_chk_fail_local" is missing when building "libl4util.so" (see below). A quick objdump/grep doesn't show this symbol in any object file in the build directory - is the build system slightly broken? I see the source definition but don't really want to hack around in the build system.

Could you do a 'make clean' and 'make V=1' and check whether a '-fno-stack-protector' is there somewhere on the gcc command line?
Yes, I see -fno-stack-protector on the gcc calls, for example:

Ok, guessed so. There's another one: -fno-stack-protector-all, could you add this one to GCCNOSTACKPROTOPT_f in l4/mk/Makeconf and do make oldconfig and redo? Does it make a difference? Could be this is a F13 specific thing, we'll see.
