Ports revision r345674
>Description:
The multimedia/gstreamer-ffmpeg port fails during configuration if clang 3.4
is the system compiler.
checking for gcc... cc
checking whether the C compiler works... no
configure: error: in `/usr/ports/multimedia/gstreamer-ffmpeg/work/gst-ffmpeg-0.10.13':
configure: error: C compiler cannot create executables
See `config.log' for more details
===> Script "configure" failed unexpectedly.
The config.log file shows the actual reason for the failure:
configure:3939: checking whether the C compiler works
configure:3961: cc -O2 -pipe -march=athlon64 -fno-force-addr -msse -fno-strict-a
liasing -Wl,-Bsymbolic conftest.c >&5
cc: error: unknown argument: '-fno-force-addr'
configure:3965: $? = 1
configure:4003: result: no
configure: failed program was:
| /* confdefs.h */
>How-To-Repeat:
Attempt to build multimedia/gstreamer-ffmpeg on a machine with clang
version 3.4 as the system compiler.
>Fix:
The following patch allows the port build to succeed:
