As discussed in #gentoo-embedded I'm compiling for a new platform. Uclibc has some problems: clibc/4.3.1/include -DNDEBUG -fpic -c lckpwdf.c -o lckpwdf.o In file included from ../../include/asm/sigcontext.h:6, from ../../include/bits/sigcontext.h:28, from ../../include/signal.h:309, from lckpwdf.c:24: ../../include/asm/ptrace.h:4:29: error: asm/arch/ptrace.h: No such file or directory In file included from ../../include/bits/sigcontext.h:28, from ../../include/signal.h:309, from lckpwdf.c:24: ../../include/asm/sigcontext.h:18: error: field 'regs' has incomplete type make[2]: *** [lckpwdf.o] Error 1 make[2]: *** Waiting for unfinished jobs.... crisv32-axis-linux-uclibc-strip -x -R .note -R .comment __parsespent.o make[2]: Leaving directory `/var/tmp/portage/cross-crisv32-axis-linux-uclibc/uclibc-0.9.28.3-r7/work/uClibc-0.9.28.3/libc/pwd_grp' make[1]: *** [_dir_pwd_grp] Error 2 make[1]: Leaving directory `/var/tmp/portage/cross-crisv32-axis-linux-uclibc/uclibc-0.9.28.3-r7/work/uClibc-0.9.28.3/libc' With respect to limit.h there are some other include errors, I wonder what the actual problem is in this case. If it is the ptrace.h that is not found or the regs having an incomplete type. Reproducible: Always
The incomplete type for "regs" is a result of the missing ptrace.h, because ptrace.h defines struct pt_regs. Looks like your cris kernel headers have problems, they don't seem quite right in mainline kernels right now http://article.gmane.org/gmane.linux.kernel/721394/match=cris+header+brokenness I think in your case either asm/arch-v10 or asm/arch-v32 should be linked as /usr/include/asm/arch, so that the proper version of ptrace.h will be found.
That patch mentioned there is available in a different form in the current 2.6.26. Now I presume the problem is in tc-arch-kernel (Linux headers). Since cris is not defined it will go inho the eclass kernel-2 and end up in: *) dodir ${ddir}/asm cp -pPR "${S}"/include/asm/* ${D}/${ddir}/asm ;; Shouldn't that copy everything? The second thing is ofcourse the symlink to 'arch'.

Created attachment 164763 [details, diff] Get cris and old pthreads working... We need to work on the headers that are included, but this patch is probably fixing the compilation issue.
please submit cris patches upstream. we'll review+merge them there.
