openjpeg port erroneously tries to link against absent libpng15

[trg818 (Thomas Ruedas)]

In the course of a more comprehensive upgrade involving ffmpeg and gtk2, I have to rebuild openjpeg, on which ffmpeg depends. This build fails, because it tries to link against libpng15, which is absent from my system, instead of linking against libpng14, which is installed and active. The screen output is:

config.log for openjpeg build

[neverpanic (Clemens Lang)]

From the looks of your config.log, pkg-config --exists --print-errors "libpng15 zlib" doesn't signal any problems, so the configure script assumes you have libpng15 installed.

Please provide the output of pkg-config --cflags --libs --print-errors libpng15, please search your system for any installed files named libpng15.pc and attach them.

[neverpanic (Clemens Lang)]

Actually, further down in your config.log the result of pkg-config --cflags libpng15 and pkg-config --libs libpng15 is already present:

820	PNG_CFLAGS='-I/opt/local/include/libpng15 -I/opt/local/include  '
821	PNG_LIBS='-L/opt/local/lib -lpng15 -lz  '

It seems your previous installation of libpng15 has not been correctly and completely removed.

[trg818 (Thomas Ruedas)]

Yes, it turns out that the include files of an old libpng15 installation were still there. I removed them, and openjpeg and ffmpeg now build correctly. Sorry for bothering.

~> pkg-config --cflags --libs --print-errors libpng15
Package libpng15 was not found in the pkg-config search path.
Perhaps you should add the directory containing `libpng15.pc'
to the PKG_CONFIG_PATH environment variable
