matrix2png installation in MAC OSX and libpng-1.6.17

Question

I'm trying to install matrix2png.

So, I have installed libpng using Homebrew.

But, when I type ./configure to install matrix2png, the following error message comes up:

You need to have libpng installed and findable by the configure script

Please help me solve this problem.

Answer 1

Try running:

brew info libpng

to see where libpng is installed.

Sample Output

libpng: stable 1.6.17 (bottled)
Library for manipulating PNG images
http://www.libpng.org/pub/png/libpng.html
/usr/local/Cellar/libpng/1.6.16 (17 files, 1.3M)
  Poured from bottle
/usr/local/Cellar/libpng/1.6.17 (17 files, 1.2M) *

Then try running

./configure --help

to see how to add a parameter to ./configure to tell it where to find libpng now that you know that from the first step. As a pure guess, you'll probably need something along the lines of

./configure --libdir=/usr/local/Cellar/libpng/1.6.16/lib
