Cross canadian gcc configuration

Cross canadian gcc configuration

[Alfonso Tamés]

Hi,

I just bitbaked an arm based (freescale) Yocto Master image and 
populated an sdk with -c populate_sdk.

When I try to compile a hello world program with the 
arm-poky-linux-gnueabi-gcc compiler, first I get an error not finding 
<stdio.h>, and when I pass the directory through the -I flag, I get the 
classic"stubs.h:7:29: fatal error: gnu/stubs-soft.h: No such file or 
directory" error which I supposed is being thrown since gcc cross 
canadian is not being configured by default (as my image) hard float.

I noticed in the gcc-cross-canadian.inc that the --with-gxx-include-dir 
and --with-sysroot in EXTRA_OECONF_PATHS have a "/not/exist" string:

EXTRA_OECONF_PATHS = "\
--with-gxx-include-dir=/not/exist${target_includedir}/c++/${BINV} \
--with-build-time-tools=${STAGING_DIR_NATIVE}${prefix_native}/${TARGET_SYS}/bin 
\
--with-sysroot=/not/exist \
--with-build-sysroot=${STAGING_DIR_TARGET} \
"

Shoudn't it be ${SDKPATH} instead of "/not/exist" ?

I think that would resolve not finding the include dirs. Now, for the 
environment not picking a hard float image and producing a 
gcc-cross-canadian accordingly, where should I be looking?

Thanks,

Alfonso

The sysroot is poisoned by intention. Try sourcing the environment script
from the SDK, and use $CC instead of invoking the compiler binary directly.

See git commit 04b725511a505c582a3abdf63d096967f0320779 in

Thanks Jakob, I am indeed sourcing the environment script. I suppose it is lacking something.

But are you calling the compiler using $CC?

Cheers,
Anders
