Through this I've found a few common issues, some of which are due to limitations of lld or choices made = by its authors, and some of which are problems in the ports themselves. audio/= oss is affected by one of the latter cases. Normally $LDFLAGS contains flags passed to the compiler driver when invoked= for linking. One issue that affects a small number of ports is passing $LDFLAGS= to direct linker invocation (i.e, $LD $LDFLAGS ...), when $LDFLAGS contains fl= ags that are appropriate only for the compiler driver, not the linker. At one point in the build -fPIC is passed to ld, which is accepted by GNU B= FD ld although it results in a bogus DT_AUXILIARY entry in the output: % readelf -d work/.build/target/lib/libossmix.so Dynamic section at offset 0x5000 contains 15 entries: Tag Type Name/Value 0x000000007ffffffd AUXILIARY Auxiliary library: [PIC] ... while lld produces an error: ld -shared -fPIC -o ../../target/lib/libossmix.so ./libossmix_cache.o ./libossmix_local.o ./libossmix_main.o ./libossmix_tcp.o ld: error: unknown argument: -fPIC Referenced Bugs: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D214864 [Bug 214864] [exp-run] test build with lld as /usr/bin/ld --=20 You are receiving this mail because: You are the assignee for the bug.=
