#28182: gst-ffmpeg fails to build when using i386 arch and 10.5 target -------------------------------------------------+-------------------------- Reporter: andres.colubri@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 1.9.2 Keywords: gstreamer, ffmpeg, build error, asm | Port: gst-ffmpeg -------------------------------------------------+-------------------------- Changes (by ryandesign@…): * cc: andres.colubri@… (removed) * port: => gst-ffmpeg Old 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 } }

Your change is unnecessary in this case anyway; you should just set "macosx_deployment_target 10.5" in macports.conf. -- Ticket URL: <https://trac.macports.org/ticket/28182#comment:5> MacPorts <http://www.macports.org/> Ports system for Mac OS
