Compiling For Multiple Architectures (Bash Reference Manual)
10.3 Compiling For Multiple Architectures
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
make that supports the
VPATH variable, such as GNU
cd to the directory where you want the object files and executables to go and run the
configure script from the source directory (see Basic Installation). 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
VPATH 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
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.
