--- Comment #11 from commit-h...@freebsd.org --- A commit references this bug: Author: jhale Date: Mon Jul 31 12:16:28 UTC 2017 New revision: 446956 URL: https://svnweb.freebsd.org/changeset/ports/446956 Log: MFH: r446955 Fix build on armv6. The -funsafe-math-optimizations flag in Clang (pulled in by -ffast-math) is emitting references to the sincos() function which is not implemented on versions of FreeBSD < 1200032. Workaround by adding -fno-unsafe-math-optimizations to armv6 CFLAGS. /bin/sh ../libtool --tag=CC --mode=link /nxb-bin/usr/bin/cc -D_THREAD_SAFE -pthread -O2 -pipe -O3 -ffast-math -fstrict-aliasing -fomit-frame-pointer -o bench bench-bench.o bench-hook.o bench-fftw-bench.o ../threads/libfftw3_threads.la ../libfftw3.la ../libbench2/libbench2.a -lm libtool: link: /nxb-bin/usr/bin/cc -D_THREAD_SAFE -pthread -O2 -pipe -O3 -ffast-math -fstrict-aliasing -fomit-frame-pointer -o .libs/bench bench-bench.o bench-hook.o bench-fftw-bench.o ../threads/.libs/libfftw3_threads.so ../.libs/libfftw3.so ../libbench2/libbench2.a -lm -pthread -Wl,-rpath -Wl,/usr/local/lib ./libbench2/libbench2.a(verify-lib.o): In function `aphase_shift': verify-lib.c:(.text+0x578): undefined reference to `sincos' ./libbench2/libbench2.a(verify-lib.o): In function `tf_shift': verify-lib.c:(.text+0x13a0): undefined reference to `sincos' verify-lib.c:(.text+0x16e4): undefined reference to `sincos' cc: error: linker command failed with exit code 1 (use -v to see invocation) gmake[3]: *** [Makefile:400: bench] Error 1 gmake[3]: Leaving directory '/wrkdirs/usr/ports/math/fftw3/work/fftw-3.3.6-pl2/tests' gmake[2]: *** [Makefile:684: all-recursive] Error 1 gmake[2]: Leaving directory '/wrkdirs/usr/ports/math/fftw3/work/fftw-3.3.6-pl2' gmake[1]: *** [Makefile:549: all] Error 2 gmake[1]: Leaving directory '/wrkdirs/usr/ports/math/fftw3/work/fftw-3.3.6-pl2' *** Error code 1 PR: 220590 Submitted by: jbeich Approved by: ports-secteam (blanket) Changes: _U branches/2017Q3/ branches/2017Q3/math/fftw3/Makefile -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ freebsd-toolchain@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-toolchain To unsubscribe, send any mail to "freebsd-toolchain-unsubscr...@freebsd.org"
