You do not understand the basic thing. The PROBLEM is to make all ports
install into one dir, but be runnable from another. As simple as that.
Imagine a software like that:
--- foo.c
#include <stdlib.h>
int main() {
return system("cat "DATAFILE);
}
--- datafile.dat
Hello, world!
--- Makefile
PREFIX?=3D /usr/local
DATADIR?=3D ${PREFIX}/share/foo
all: foo
foo: foo.c
cc -DDATAFILE=3D\"${DATADIR}/datafile.dat\" foo.c -o foo
install: foo datafile.dat
install -s foo ${PREFIX}/bin
install -d ${DATADIR}
install datafile.dat ${DATADIR}
---
As you can see, if this is installed with PREFIX=3D/var/tmp/foobar,
then moved to /usr and ran, it won't work, as it has DATAFILE
compiled in as "/var/tmp/foobar/share/foo/datafile.dat" instead of
"/usr/local/share/foo/datafile.dat".
To make it behave as we indend, you'll have to either hack Makefile
to distinguish DESTDIR and PREFIX, or do all installation in port's
Makefile by yourself.
We have around 20k ports, and it will be extremely hard task to
convert them all to such scheme (though afaik configure-based ones
should support this without modifications). The example above is
quite simple, the real life can be much more ugly, I assure. The
worst thing is that we won't be able to test ports automatically,
as the fact the port builds and installs successfully won't mean
that it will run without problems.
I wonder how debian and gentoo get around this problem...
