bash: Compiling For Multiple Architectures
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 'make'. 'cd' to the directory where
you want the object files and executables to go and run the '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 '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 '/usr/gnu/src/bash-2.0':
bash /usr/gnu/src/bash-2.0/support/mkclone -s /usr/gnu/src/bash-2.0 .
The '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.
