bug#19831: 25.0.50; Can't build emacs 25.0.5 with libpng16 support (only libpng15) |
Date: |
Tue, 10 Feb 2015 17:40:37 -0500 |
User-agent: |
Gnus/5.13 (Gnus v5.13) Emacs/25.0.50 (gnu/linux) |
I see:
$ libpng-config --cflags
-I/home/torys/anaconda/include/libpng15
So, I uninstalled libpng and reinstalled it, carefully using the package and
following the directions from http://www.libpng.org/pub/png/libpng.html
And yet, to my frustration, afterwards I STILL received:
$ libpng-config --cflags
-I/home/torys/anaconda/include/libpng15
I can't seem to get around this. Any suggestions would be appreciated.
