Hi

Some of you may remember me from old times. Recently I got some work to do related with OpenEmbedded but I need working toolchain on target device.

I use openembedded-core and got few problems with "core-image-lsb-sdk" on qemux86 target (final image will be armv7 or even armv8 later).

First thing: binutils - "ld: this linker was not configured to use sysroots" even with simple hello.c source. Fix attached.

Second thing: gcc (or rather g++) which is unable to find STL headers (after installing libstdc++-dev package):

ignoring nonexistent directory "usr/include/c++/" ignoring nonexistent directory "usr/include/c++//i586-oe-linux" ignoring nonexistent directory "usr/include/c++//backward" ignoring nonexistent directory "/usr/local/include" ignoring nonexistent directory "/usr/lib/gcc/i586-oe-linux/4.7.1/../../../../i586-oe-linux/include" #include "..." search starts here:
.
#include <...> search starts here:
..
../lib
/usr/lib/gcc/i586-oe-linux/4.7.1/include /usr/lib/gcc/i586-oe-linux/4.7.1/include-fixed /usr/include
../lib/compat
End of search list.

So far I did not looked at fixing this part but will do as I want to be able to build anything on target.

So what status is of C/C++ toolchain in OE-Core?

"ld: this linker was not configured to use sysroots" was what I got on device instead of compiled binary.

includedir already has leading slash so I wonder if you changed includedir in your setup somehow ?

bitbake gcc -e|grep ^includedir shown "/usr/include" value. G++ started on target as "g++ -v" shown "--with-c++-includes=/usr/include/c++" so I was surprised when it was not working.

Added extra slash and it works. But please check in your configuration.

can you try the fixes from my branch

this should fix both gcc and binutils on target

I am still building one image from scratch but my build with gcc-linaro and your fix-g++-sysroot.patch applied works perfectly:
