You can compile Bash for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you must use a version of
VPATH variable, such as GNU
cd to the
directory where you want the object files and executables to go and run
configure script from the source directory. You may need to
supply the `--srcdir=PATH' argument to tell
configure where the
source files are.
configure automatically checks for the
source code in the directory that
configure is in and in `..'.
If you have to use a
make that does not supports the
variable, you can compile Bash for one architecture at a
time in the source code directory. After you have installed
Bash for one architecture, use `make distclean' before
reconfiguring for another architecture.
Alternatively, if your system supports symbolic links, you can use the `support/mkclone' script to create a build tree which has symbolic links back to each file in the source directory. Here's an example that creates a build directory in the current directory from a source directory `/usr/gnu/src/bash-2.0':
bash /usr/gnu/src/bash-2.0/support/mkclone -s /usr/gnu/src/bash-2.0 .
mkclone script requires Bash, so you must have already built
Bash for at least one architecture before you can create build
directories for other architectures.
