You may find it convenient to create links whose destinations depend upon
results of tests. One can use
AC_CONFIG_COMMANDS but the
creation of relative symbolic links can be delicate when the package is
built in another directory than its sources.
AC_OUTPUTlink each of the existing files source to the corresponding link name dest. Makes a symbolic link if possible, otherwise a hard link. The dest and source names should be relative to the top level source or build directory. This macro is one of the instantiating macros, see 4.5 Taking Configuration Actions.
For example, this call:
creates in the current directory `host.h' as a link to `srcdir/config/$machine.h', and `object.h' as a link to `srcdir/config/$obj_format.h'.
The tempting value `.' for dest is invalid: it makes it impossible for `config.status' to guess the links to establish.
One can then run:
./config.status host.h object.h
