Hi Waldemar, I discovered an issue with uClibc and binutils 2.32 and gcc 9.1 or 9.2. LD libuClibc-1.0.31.so /opt/openrisc--uclibc--bleeding-edge-1/lib/gcc/or1k-buildroot-linux-uclibc/9.2.0/../../../../or1k-buildroot-linux-uclibc/bin/ld: libc/libc_so.a(or1k_clone.os): pc-relative relocation against dynamic symbol __syscall_error See: https://gitlab.com/kubu93/toolchains-builder/-/jobs/270854456 This error message come from a new check in binutils 2.32.x: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commitdiff;h=f2c… With binutils 2.30.x and 2.31.x, I have another assembler error: Error: junk at end of line `l.movhi r17,gotoffha(.LC0)' ork1 support was added to gcc 9.x and enabled into Buildroot recently. https://git.buildroot.net/buildroot/commit/?id=da70a55a1955ff673e0110bacb3d… I remember doing a test with qemu_or1k_defconfig before gcc 9.1 was released but I don't remember if it was with musl or uClibc-ng... It should be with uClibc-ng but I didn't trigged such error. Thoughts ? Best regards, Romain
