Subject: [PATCH] configure.ac: fixup $CC --print-multiarch output for
|
|
musl/uclibc GCC 8+ toolchains
|
|
|
|
GCC commit 6834b83784dcf0364eb820e8 (multiarch support for non-glibc linux
|
|
systems), which is part of GCC 8+, changed the multiarch logic to use
|
|
$arch-linux-musl / $arch-linux-uclibc rather than $arch-linux-gnu.
|
|
|
|
This then causes the python3 configure script to error out:
|
|
|
|
checking for the platform triplet based on compiler characteristics... powerpc-linux-gnu
|
|
configure: error: internal configure error for the platform triplet, please file a bug report
|
|
|
|
http://autobuild.buildroot.net/results/cb4/cb49c539501342e45cbe5ade82e588fcdf51f05b
|
|
|
|
As it requires that the --print-multiarch output (if not empty) matches the
|
|
deduced triplet (which always uses -linux-gnu).
|
|
|
|
It isn't quite clear why --print-multiarch returns something for a
|
|
non-multiarch toolchain on some architectures (E.G. PowerPC), but as a
|
|
workaround, rewrite the --print-multiarch output to match older GCC versions
|
|
to keep the configure script happy.
