I disagree strongly. It is irrelevant where the libraries are installed on a specific distribution. If they are INSTALLED, this means that they can be found by the compiler when requesting them (via -lpng). If the operating system does not install libraries where they can be found, this is a bug in the operating system. It can be easily solved by adding the directory to the LIBRARY_PATH environment variable. export LIBRARY_PATH=$LIBRARY_PATH:/usr/lib/x86_64-linux-gnu The makefile is correct as it is, and the custom path should not be added. If we want to solve a particular bug of a particular operating system, we can still do it by putting the line above in a custom script "ubuntu-fix-bug.sh", which is to be called before running the makefile, and it sets the relevant variables, or whatever is needed. -- IPOL - Image Processing On Line - http://ipol.im/ contact e...@ipol.im - http://www.ipol.im/meta/contact/ news+feeds twitter @IPOL_journal - http://www.ipol.im/meta/feeds/ announces annou...@list.ipol.im - http://tools.ipol.im/mm/announce/ discussions discuss@list.ipol.im - http://tools.ipol.im/mm/discuss/
