[SOLVED] Can't override libpng15 with newer install

Issue

I've downloaded and installed libpng from http://www.libpng.org/pub/png/libpng.html, which is version 1.6.16, following their simple instructions:

• ./configure
• ./make check
• sudo ./make install

It runs with everything successful, and says it's been installed. However, after doing this I still read:

$ libpng-config --cflags --ldflags
-I~/anaconda/include/libpng15
-L~/anaconda/lib -lpng15

This is breaking other builds and installs, which sometimes detect 15 while requiring 16. How can I fix this?

Solution

If you want libpng16 to go in your $HOME/ then, in your libpng directory, run

./configure --prefix=$HOME
./make
./make install

This will install png*.h in $HOME/include/, libpng-config in $HOME/bin/, and the library itself in $HOME/lib/.

If you want to put it in some other directory where you don't have write permission, the final command is

sudo ./make install
