14.7.2 Transformation Examples

These transformations are useful with programs that can be part of a
cross-compilation development environment.  For example, a
cross-assembler running on a Sun 4 configured with
`--target=i960-vxworks' is normally installed as `i960-vxworks-as',
rather than `as', which could be confused with a native Sun 4 assembler.

   You can force a program name to begin with `g', if you don't want
GNU programs installed on your system to shadow other programs with the
same name.  For example, if you configure GNU `diff' with
`--program-prefix=g', then when you run `make install' it is installed
as `/usr/local/bin/gdiff'.

   As a more sophisticated example, you could use

     --program-transform-name='s/^/g/; s/^gg/g/; s/^gless/less/'
   to prepend `g' to most of the program names in a source tree,
excepting those like `gdb' that already have one and those like `less'
and `lesskey' that aren't GNU programs.  (That is assuming that you
have a source tree containing those programs that is set up to use this

   One way to install multiple versions of some programs simultaneously
is to append a version number to the name of one or both.  For example,
if you want to keep Autoconf version 1 around for awhile, you can
configure Autoconf version 2 using `--program-suffix=2' to install the
programs as `/usr/local/bin/autoconf2', `/usr/local/bin/autoheader2',
etc.  Nevertheless, pay attention that only the binaries are renamed,
therefore you'd have problems with the library files which might
