make install to another dir?

I'm building a linux system within a running one.  The work in progress is mounted on /mnt/cf, and I just compiled bash and I want to install it to /mnt/cf instead of / with a make install.  What flags would I use to do this?

./configure --prefix=/mnt/cf/usr
make
make install

Re: make install to another dir?

it's probably a a better idea to change the make prefix ,, the configure is usually there to sort out where the programs looks for stuff
so
make DESTDIR=/mnt/cf install
or
make [prefix|PREFIX]=/mnt/cf install
the first is used in most apps ive come accross but are few are stubborn and doesn't follow the convention as i see it

No, the --prefix option to configure sets the installation target path, and is the Right Way (tm) to mess with said path.  Among other circumstances, the "make DESTDIR=/mnt/cf install" solution fails when the compilation itself uses the install path as a parameter (such as the case where shared files are expected in $PREFIX/share or configuration is expected in $PREFIX/etc).

But the program run on the new system will not have a /mnt/cf prefix.
When you compile it like that, it will only work if it doesn't need any external resources, afaik.

So ./configure --prefix=/usr
make
make DESTDIR=/mnt/cd/usr install

Like the PKGBUILDs do it, right?

Duh, good point.  I had forgotten that he was installing to an alternate root as opposed to just an alternate path.

Use the Linux From Scratch book for all the hints you need to do this...

Nice, LFS is a great book.  I remember it being overly complicated years ago, now I skip through chapters ... funny how that happens!
