Looks like the relocation scripts fails for environments: ~/tests/poky [master] $ cat /opt/oel/2014-01-01/environment-setup-ppce500v2-oel-linux | grep "#" export SDKTARGETSYSROOT=##SDKTARGETSYSROOT## ~/tests/poky [master] $ cat /opt/oel/2014-01-01/environment-setup-ppce500v2-oel-linux-gnuspe | grep "#" 2. SDK gnuspe compiler does not allow -mabi=spe ABIEXTENSION is zeroed both for linux-gnuspe and linux 3. Compiler can't create executables. I think this is due to libgcc_s.so from the SDK target sysroot is in mabi=spe. 4. -mspe is included in CC var for both linux and gnuspe. cat /opt/oel/2014-01-01/environment-setup-ppce500v2-oel-linux | grep mabi export CC="powerpc-oel-linux-gcc -m32 -mcpu=8548 -mabi=spe -mspe -mfloat-gprs=double --sysroot=$SDKTARGETSYSROOT" export CXX="powerpc-oel-linux-g++ -m32 -mcpu=8548 -mabi=spe -mspe -mfloat-gprs=double --sysroot=$SDKTARGETSYSROOT" export CPP="powerpc-oel-linux-gcc -E -m32 -mcpu=8548 -mabi=spe -mspe -mfloat-gprs=double --sysroot=$SDKTARGETSYSROOT" Seems to work in dora though, Any thoughts on this ?
