Hi Jan,
I had to change
- oe_runmake
+ oe_runmake CC="$CC"
for recent yocto versions. What was your fix?
My fix was more complicated, by exporting ${TOOLCHAIN_OPTIONS} and
${HOST_CC_ARCH}. Thanks for this simpler solution.
The option "-mfloat-abi=soft" is used in barebox compilation, which
seems not supported by gcc. Adding "-mfloat-abi=hard" is not enough, the
original "-mfloat-abi=soft" should be removed. Unfortunately, i could
not find where this option is added and how to remove it.
Can anybody help me to fix it?
Which yocto and gcc version are you using? Could you show us the actual
error messages and yocto recipe?
The current fido and master branches use gcc 4.9.2 and the problem is
that soft float abi support seems missing and the option
-mfloat-abi=soft is always added by the make rules of barebox.
If i use the above mentioned fix, the result is:
arm-poky-linux-gnueabi-gcc: error: -mfloat-abi=soft and -mfloat-abi=hard
may not be used together
because -mfloat-abi=hard is passed in ${CC} variable.
If i remove the option -mfloat-abi=hard, then got this error:
... stubs.h:7:29: fatal error: gnu/stubs-soft.h: No such file or directory
that's why i think the soft abi support is missing.
IMHO the float abi should not be set by the make rules because it is
hardware specific, and therefore should be set by the build system.
