[Fink-users] gs and libpng problems

[Martin Costabel]

Testing a newly built scribus, I found that I could no longer import eps graphics. The reason is that ghostscript-8 does not have the png16m device that exists in ghostscript6 (nor the other png devices).

In the ghostscript build log I found the following

checking for deflate in -lz... yes
checking for local png library source... no
checking for png_check_sig in -lpng... no
no
configure: disabling png output devices

In config.log I see the following

configure:5351: checking for png_check_sig in -lpng
configure:5384: gcc -o conftest -g -O2 -I/sw/include -L/sw/lib conftest.c -lpng  -lm  >&5
ld: Undefined symbols:
_crc32
_inflateReset

Indeed, these symbols are undefined in libpng.dylib (both version 2 and 3). They are defined in /usr/lib/libz.dylib, but this library is nowhere included.

Something is not right here, but I don't know who to blame, libpng or the ghostscript configure script.

Does everyone else have the png devices in ghostscript versions 7 or 8 ("gs -h") ?
