Bug 246234 – media-plugins/vdr-graphtft-0.1.21_alpha: does not link as libswscale is missing

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Petric Frank 2008-11-10 00:05:20 UTC]

Durung link of the vdr module it fails because it does not find swscale library.



Reproducible: Always

Steps to Reproduce:
1. unmask vdr-graphtft-0.1.21_alpha
2. emerge vdr-graphtft
3.

Actual Results:

[Comment 2 Wormo (RETIRED) 2008-11-10 07:39:09 UTC]

Apparently this needs an ffmpeg version that has swscale enabled. Try upgrading to a testing version of ffmpeg, and the maintainers might want to make the ffmpeg dependency more specific.

[Comment 3 Petric Frank 2008-11-11 05:35:58 UTC]

I've umasked ffmpeg-0.4.9_p20070616-r20 which should have (according to ChangeLog) swscale support enabled.

Now i get another error:

Current stable ffmpeg on my system is ffmpeg-0.4.9_p20070616-r3

Any other hints ?

[Comment 4 Petric Frank 2008-11-11 05:39:57 UTC]

Oh i forgot - imagemagick (media-gfx/imagemagick-6.4.0.6) is installed. The missing file exists and can be located at /usr/include/ImageMagick/Magick++.h

Coding probem ?

[Comment 5 Matthias Schwarzott 2009-01-10 15:41:13 UTC]

Maybe Magick++.h was installed in /usr/include in the past and now moved to /usr/include/ImageMagick.

If so, we could either patch the #include lines, or add -I/usr/include/ImageMagick to compiler params. (CPPFLAGS)

How I fixed it for my. 

change scr_compile() to

src_compile() {
        vdr-plugin_src_compile

        if use graphtft-fe; then
                cd "${S}"/graphtft-fe
                cp "${FILESDIR}/build.sh.mod" build.sh
                ./clean.sh
                ./build.sh || die "build.sh failed"
        fi
}

edit /usr/portage/media-plugins/vdr-graphtft/files/build.sh.mod like this. 

#/usr/bin/qmake -project
#/usr/bin/qmake

qmake -project
qmake

# patch the makefile

mv Makefile Makefile.bak
cat Makefile.bak | sed -e '/LIBS.* =/a\LIBS += `imlib2-config --libs` `/usr/bin/Magick++-config --libs`' > Makefile
mv Makefile Makefile.bak
cat Makefile.bak | sed -e '/INCPATH.* =/a\INCPATH += -I/usr/include/ImageMagick' > Makefile
make -s
