Description

In the original case, toolchain wrappers were missing for the 32-bit toolchain when creating an SDK in a multilib project. The wrappers are now available but parts of the 32-bit sysroot seem to be missing so it is still not possible to compile a 32-bit application.

Workaround

The attatched patch to wr-tcwrappers layer should address the problem.

Steps to Reproduce

$ configure --enable-board=intel-x86-64 \
        --enable-rootfs=glibc_std --enable-kernel=preempt_rt \
        --with-template=feature/toolchain-wrappers

Edit local.conf to add:
MULTILIBS = "multilib:lib32"
DEFAULTTUNE_virtclass-multilib-lib32 = "x86"

$ make export-sdk

Install the SDK. Attempt to build a simple hello world application.

$ /opt/windriver/intel-x86-64-glibc_std-preempt_rt-60p16-tcw/sysroots/x86_64-wrlinuxsdk-linux/usr/bin/x86_64-wrs-linux/x86_64-wrswrap-linux-gnu-gcc hello.c

$ file a.out
a.out: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.34, not stripped

$ rm a.out

$ /opt/windriver/intel-x86-64-glibc_std-preempt_rt-60p16-tcw/sysroots/x86_64-wrlinuxsdk-linux/usr/bin/i586-wrsmllib32-linux/x86-wrsmllib32wrap-linux-gnu-gcc hello.c
hello.c:1:19: fatal error: stdio.h: No such file or directory
 #include <stdio.h>
                   ^
compilation terminated.

The 64-bit wrapper works but not the 32-bit.
