Custom prefixes for GNU automake configure scripts using config.site
Recently, I had to compile a bunch of stuff on a system where I don’t have root access. Since I want to be able to “install” it in a tree that mirrors the system root
/ (e.g. put stuff in
/usr/, etc.), that required using a custom
--prefix for the output:
./configure --prefix=$HOME/prefix make install
Now everything’s under
$HOME/prefix, e.g. something which would otherwise be installed in
/bin/bla will now be at
$HOME/prefix/bin/bla. Just need to set
$PATH and everything’s good!
So far so good, but having dependencies between installed packages is problematic.
./configure won’t “see” pre-existing headers or libraries in the prefix without setting
LDFLAGS explicitly every time.
There is a solution, though - the
config.site file. Had to put the following in
configure scripts are always being able to “see” the installed stuff inside the custom prefix.
