Unfortunately, this patch is not enough. I can reproduce
http://autobuild.buildroot.net/results/f28/f28980613173fd3fdd216218ab3ced92e01adb2b/build-end.log:
/home/buildroot/build/instance-0/output/host/opt/ext-toolchain/bin/../lib/gcc/bfin-buildroot-linux-uclibc/6.3.0/../../../../bfin-buildroot-linux-uclibc/bin/ld: LINKER BUG: .rofixup section size mismatch
/home/buildroot/build/instance-0/output/host/opt/ext-toolchain/bin/../lib/gcc/bfin-buildroot-linux-uclibc/6.3.0/../../../../bfin-buildroot-linux-uclibc/bin/ld: final link failed: Nonrepresentable section on output
with the following defconfig:
BR2_bfin=y
BR2_ENABLE_DEBUG=y
BR2_TOOLCHAIN_BUILDROOT_CXX=y
BR2_PACKAGE_IBRDTND=y
Note that BR2_ENABLE_DEBUG=y is important for the issue to happen.
Without it, it doesn't happen.
We have the same problem on the stella package:
http://autobuild.buildroot.net/results/748/7483123d5cdc4637f298d7edc5910751b27791ec/build-end.log
(with BR2_ENABLE_DEBUG=y as well)
On the icu package:
http://autobuild.buildroot.net/results/4e8/4e87cb455df98a9a5dcc55f39df881c63bd00158/build-end.log
(this one without BR2_ENABLE_DEBUG)
Do you have an idea on how to solve this ? The upstream bug report has
been made 6 years ago, with no reaction, so I doubt we can hope to get
any sort of help from upstream :-/
Thanks!
Thomas
