Need to compile program linked to earlier version of a lib

sadrok

I wish to compile a program used for CGI
Currently it links to libpng-1.2.5-r4 (/usr/lib/libpng.so.3)
But I want it to run on a webhost that only has (/usr/lib/libpng.so.2)
How can this be done?

I'm assuming you don't have root access on that system, so you can't upgrade?

You could compile the new libpng you need and keep it in your home directory and point to that version (libpng-1.2.5-r4) in the CGI program's Makefile.

Compile libpng.so.3 but don't do 'make install', unless you've already configured your Makefile to install it in your home directory somewhere.

Go to your CGI program's Makefile and look for a line that has something like:

LIBS = -L/usr/lib -llibpng etc.

You'll want to add the directory where your new copy of libpng.so.3 is then compile it.
