I tried (apparently successfully) to install
libpng on mac os x mavericks.
I downloaded the latest 1-6-8 version
.tar.xz and followed the instructions.
./configure runs fine
make check passes everything but png-error that gets skipped
sudo make install apparently works fine since my library libpng. appears.
Now, when i try to compile the C file that i need to compile, using the string
clang -w -lz -lpng16 libpng_test.c
i get the error
fatal error: 'png.h' file not found
and obviously it does not compile.
I tried installing both with homebrew and macports and it always seems to run fine, but i always get the same errorAnswer1:
First you have to find where the png.h file is located
sudo find / -name png.h
Here in my environment it is located at <strong>/usr/local/include</strong>
Then look for libpng.a
sudo find / -name libpng.a
Here in my environment it is located at <strong>/usr/local/lib</strong>
Now add those directories to the clang command line:
clang -I/usr/local/include -L/usr/local/lib -w -lz -lpng16 libpng_test.c
