[yocto] Error in configuring multilib ie libstdc++ for c++

[Rohit2 Jindal]

Hi ,

Actually we had two toolchains one for linux(linux kernel and other userspace component ) components and other elf toolchain for bootloaders (like xloader uboot and sysconfig) compilations. We have tried to compile both the toolchains using yocto  for 4.6.3 version and working fine for language=c only. But we have issue that I am not able to create libstd* libraries by setting extra_oeconf enable-language=c,c++ for elf toolchain and its giving error in compilation steps .

Please suggest me the solution.

Hi,

I am trying to compile both c and c++ multilib for elf toolchain but its giving error in configuring the same for c++. Logs are attached with this mail. And EXTRA_OECONF passed are as below:

EXTRA_OECONF += "--with-sysroot=${TMPDIR}/sysroots/${BUILD_SYS}/usr/lib/mips32-nlm-elf.gcc-cross-initial/gcc/mips64-nlm-elf/4.6.3 \

you are trying to mix bare metal compiler toolchain with hosted toolchain targeting Linux ?
OpenEmbedded has concept of TARGET_OS and now you could unset it but thats a untreated territory. If you explain in essence what you are trying to do. May be there is a solution.


                --enable-threads \

                --with-gxx-include-dir=${TMPDIR}/sysroots/${BUILD_SYS}/usr/${TARGET_SYS}/usr/include/c++ \
                --enable-cxx-flags='-G0 -mno-gpopt' \

Please suggest me the way to resolve this issue.
