Re: [PATCH] Configure outside of source tree

Hi Kyle,

What is your expected usage scenario?

$ mkdir -p $HOME/devel/ct-ng/code
$ cd $HOME/devel/ct-ng/code
$ hg clone http://ymorin.is-a-geek.org/hg/crosstool-ng
$ cd crosstool-ng
$ patch -p1 < ~/crosstool-ng_configure_outside_tree.patch

$ mkdir $HOME/devel/ct-ng/build
$ cd $home/devel/ct-ng/build
$ $HOME/devel/ct-ng/code/crosstool-ng/configure --prefix=$HOME/tmp

Now run:
  make
  make install
$ make
make: *** No targets specified and no makefile found.  Stop.
$ ls


That's not what I was expecting :-)

I'm guessing this is a matter of doing things differently, but I'm not
sure what's gained by being able to configure outside the source tree
if I then have to move back to the source tree to build (or use a -C
cmdline option to 'make').
