swftools: Undefined symbols _PrintGifError

[simon.groenewolt@…]

My port install swftools fails:

(probably) relevant part of the log:

:info:build /usr/bin/clang -DHAVE_CONFIG_H swfrender.o -o swfrender ../lib/libgfxswf.a ../lib/librfxswf.a ../lib/libgfx.a ../lib/libbase.a -L/opt/local/lib -arch x86_64 -L/usr/local/lib -L/opt/local/lib -lmp3lame -lgif -ljpeg -lpdf -lz -lm  -L/opt/local/lib -lfreetype -lz -lbz2 
:info:build Undefined symbols for architecture x86_64:

:info:build clang: error: linker command failed with exit code 1 (use -v to see invocation)
:info:build make[1]: *** [gif2swf] Error 1

I've done a port selfupdate, a clean and a fresh install of swftools.

Full install log attached

Oops - this might be related to an Xcode upgrade. I will reinstall all ports en see if problem persists.

No, this is related to giflib having been updated to 4.2.0 and the PrintGifError symbol having been removed from giflib in that version. See #34541 for the same problem with gdal. I'm looking to see if updating swftools to 0.9.2 would help.

It does not, so please report the problem to the developers of swftools so they can resolve it.

Workaround: Just commenting or removing the two lines that reference PrintGifError in gif2swf.c in the downloaded source and running port install swftools again makes it work -- I guess you'll miss out on errors reported about gifs :-)

[robsonpeixoto@…]

With this patch it will compile. Based on; ​http://fossies.org/dox/giflib-4.2.0/qprintf_8c_source.html#l00041

To compile the swftools, is needed an downgrade to giflib 4.1.6 like this:

$ svn co http://svn.macports.org/repository/macports/trunk/dports/graphics/giflib -r80038
$ cd giflib

change the master_sites to : 'master_sites sourceforge:project/${name}/${name}-${major}.x/${name}-${version}'

$ sudo port install
