If you wish to build the object files and executables in a directory
other than the one containing the source files, here is what you must
do differently:
Make sure you have a version of Make that supports the VPATH
feature. (GNU Make supports it, as do Make versions on most BSD
systems.)
If you have ever run `configure' in the source directory, you must undo
the configuration. Do this by running:
make distclean
Go to the directory in which you want to build the compiler before
running `configure':
mkdir gcc-sun3
cd gcc-sun3
On systems that do not support symbolic links, this directory must be
on the same file system as the source code directory.
Specify where to find `configure' when you run it:
../gcc/configure ...
This also tells configure where to find the compiler sources;
configure takes the directory from the file name that was used to
invoke it. But if you want to be sure, you can specify the source
directory with the `--srcdir' option, like this:
../gcc/configure --srcdir=../gcc other options
The directory you specify with `--srcdir' need not be the same
as the one that configure is found in.
Now, you can run make in that directory. You need not repeat the
configuration steps shown above, when ordinary source files change. You
must, however, run configure again when the configuration files
change, if your system does not support symbolic links.
