Oddly enough it works on a Ubuntu that is upgraded from 10.04 all the way up to 12.04, but not a freshly installed installed 12.04. I get problem with how the path/links are resolved somehow, so there is some compatibility issue in some lib somewhere.. My "fix" for now is to update the spec file to include the correct directories for the compiler *cpp: %{posix: -D_POSIX_SOURCE} -I /opt/eldk-4.2/usr/../ppc_82xx/usr/include %{mads : %(cpp_os_ads) ; myellowknife : %(cpp_os_yellowknife) ; mmvme : %(c$ Without the "fix" it yields this niclas.lindgren@ubuntu:~$ /opt/eldk-4.2/usr/bin/ppc-linux-gcc -v test.c Reading specs from /opt/eldk-4.2/usr/bin/../lib/gcc/powerpc-linux/4.2.2/specs Target: powerpc-linux Configured with: /opt/eldk/build/ppc-2008-04-01/work/usr/src/denx/BUILD/crosstool-0.43/build/ gcc-4.2.2-glibc-20070515T2025-eldk/powerpc-linux/gcc-4.2.2/configure --target=powerpc-linux --host=i686-host_pc-linux-gnu --prefix=/var/tmp/eldk.UZpAG7/usr/crosstool/gcc-4.2.2-glibc-20070515T2025-el dk/powerpc-linux --disable-hosted-libstdcxx --with-headers=/var/tmp/eldk.UZpAG7/usr/crosstool/gcc-4.2.2-glibc-20070515T2 025-eldk/powerpc-linux/powerpc-linux/include --with-local-prefix=/var/tmp/eldk.UZpAG7/usr/crosstool/gcc-4.2.2-glibc-20070 515T2025-eldk/powerpc-linux/powerpc-linux --disable-nls --enable-threads=posix --enable-symvers=gnu --enable-__cxa_atexit --enable-languages=c,c++,java --enable-shared --enable-c99 --enable-long-long --without-x Thread model: posix gcc version 4.2.2 /opt/eldk-4.2/usr/bin/../libexec/gcc/powerpc-linux/4.2.2/cc1 -quiet -v -imultilib m603 -iprefix /opt/eldk-4.2/usr/bin/../lib/gcc/powerpc-linux/4.2.2/ -D__unix__ -D__gnu_linux__ -D__linux__ -Dunix -D__unix -Dlinux -D__linux -Asystem=linux -Asystem=unix -Asystem=posix test.c -quiet -dumpbase test.c -mcpu=603 -auxbase test -version -o /tmp/ccZkOuwj.s ignoring nonexistent directory "/opt/eldk-4.2/usr/bin/../lib/gcc/powerpc-linux/4.2.2/../../../../powerpc-li nux/sys-include" ignoring nonexistent directory "/opt/eldk-4.2/usr/bin/../lib/gcc/powerpc-linux/4.2.2/../../../../powerpc-li nux/include" ignoring nonexistent directory "/var/tmp/eldk.UZpAG7/usr/crosstool/gcc-4.2.2-glibc-20070515T2025-eldk/power pc-linux/lib/gcc/powerpc-linux/4.2.2/include" ignoring nonexistent directory "/var/tmp/eldk.UZpAG7/usr/crosstool/gcc-4.2.2-glibc-20070515T2025-eldk/power pc-linux/powerpc-linux/sys-include" ignoring nonexistent directory "/var/tmp/eldk.UZpAG7/usr/crosstool/gcc-4.2.2-glibc-20070515T2025-eldk/power pc-linux/powerpc-linux/include" ignoring nonexistent directory "/opt/eldk-4.2/lib/gcc/powerpc-linux/4.2.2/include" ignoring nonexistent directory "/opt/eldk-4.2/powerpc-linux/sys-include" ignoring nonexistent directory "/opt/eldk-4.2/powerpc-linux/include" ignoring nonexistent directory "/opt/eldk-4.2/../ppc_82xx/usr/include" #include "..." search starts here: #include <...> search starts here: /opt/eldk-4.2/usr/bin/../lib/gcc/powerpc-linux/4.2.2/include End of search list.

GGC heuristics: --param ggc-min-expand=100 --param ggc-min-heapsize=131072 Compiler executable checksum: 1aec0482efbebeb41ccfcf839ce71331 test.c:1:20: error: assert.h: No such file or directory As you can see, it kind of gets it right ignoring nonexistent directory "/opt/eldk-4.2/../ppc_82xx/usr/include" It is just missing a "/usr" after eldk-4.2/ What is even weirder is that running ppc-82xx-cpp will yield an error, but running it with "-v" will make it work... And now for the real killer, change the root of eldk from /opt/eldk-4.2 to /opt/eldk-4.2.new makes it work (just an mv, I know some files or not correct and it should be installed, it was just for testing). Making it even weired, if I instead just link /opt/eldk-4.2 to /opt/eldk-4.2.new it won't work. But doing the opposite, that is mv /opt/eldk-4.2 to /opt/eldk-4.2.fix and then link /opt/eldk-4.2 to /opt/eldk-4.2.fix makes it work too (all this without the spec patch). Readlink, dirname and basename or my guesses, somewhere in the compiler, and thus in libc. I would guess it wouldn't had been a problem had the compilers been built statically. The difference between my working Ubuntu and 12.04 is that /lib/i386-linux-gnu/libc.so.6 has changed versions from 2.13 to 2.15. I will try to bring 2.13 to my non working Ubuntu instead and see what happens. I understand that this isn't supported and this ELDK 4.2 is old. But our HW/kernel supplier is on ELDK 4.2 and building locally on your dev machine is nice while not having to stay behind the releases and I hope this helps someone. Cheers, Niclas
