| If you: |
| |
| TCLIBC=musl bitbake unwind |
| TCLIBC=musl bitbake gcc-runtime -c cleansstate |
| TCLIBC=musl bitbake gcc-runtime |
| |
| you will see libstdc++ fail to build due to finding libunwind's header file. |
| |
| Khem: "When we build any of gcc components they expect to use internal version |
| and that works with glibc based gcc since the search headers first look into gcc |
| headers, however with musl the gcc headers are searched after the standard |
| headers ( which is by design the right thing )." |
| |
| This patch hacks around the issue by looking for a define used during gcc-runtime's |
| build and skipping to the internal header in that case. |
