Description Christopher Byrne 2010-01-19 04:50:50 UTC

mjpegtools (bug 293919) and transcode (bug 294488) require they be compiled against jpeg-6.2 . Unfortunately, the new slotted jpeg ebuilds don't provide enough to be compiled against without media-libs/jpeg-8 . 

configure:23391: i686-pc-linux-gnu-gcc -o conftest -march=pentium4 -O2 -pipe -g -fno-strict-aliasing -pthread  -Wl,--as-needed conftest.c -ljpeg  -lm  >&5
/usr/lib/gcc/i686-pc-linux-gnu/4.3.4/../../../../i686-pc-linux-gnu/bin/ld: cannot find -ljpeg
collect2: ld returned 1 exit status
configure:23397: $? = 1
[test program omitted]
configure:23415: result: no
configure:23425: error: JPEG 6b library missing - Go to http://www.ijg.org/

Note that the compiling problem is not limited to mjpegtools, NOTHING compiles against the new slotted ebuild without media-libs/jpeg-8 .

So as things stand now in Portage, there's NO way to compile a working mjpegtools / trasncode without the old ebuild.

The slotted versions are only for binary-only applications where recompiling isn't an option. Locally masking everything from SLOT="0" will surely break the building...

OK, I see. Well could media-libs/jpeg-6b-r8 be put back into portage? Working copies of mjegtools and transcode can't be compiled without it.
