Description
Hello, when trying to install the gst-ffmpeg package on Snow Leopard 64 bits, but using i386 as the build architecture and 10.5 as the deployment target, the build stage fails with this error:
:info:build CC libavcodec/h264_cabac.o :info:build libavcodec/cabac.h: In function 'get_cabac_noinline': :info:build libavcodec/cabac.h:527: error: PIC register '%ebx' clobbered in 'asm' ...
(full error log is attached)
I should also note that in order to generate valid 32 bits binaries for 10.5 when compiling from OSX 10.6 64 bits, I changed the default LD flags in <prefix>/share/macports/Tcl/port1.0/portconfigure.tcl as:
default configure.ldflags {"-L${prefix}/lib -Xlinker -headerpad_max_install_names -mmacosx-version-min=10.5 -no_compact_linkedit"}
I don't know if this influencing the occurrence of the error. Anyways, a solution I found to this problem was to add the the following post-configure step in the portfile of gst-ffmpeg:
post-configure {
if { $build_arch == "i386" } {
reinplace "s|HAVE_EBX_AVAILABLE 1|HAVE_EBX_AVAILABLE 0|g" \
${worksrcpath}/gst-libs/ext/ffmpeg/config.h
}
}
