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 a directory different from the source directory.
AC_OUTPUTlink each of the existing files source to the corresponding link name dest. Makes a symbolic link if possible, otherwise a hard link if possible, otherwise a copy. 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 Configuration Actions.
For example, this call:AC_CONFIG_LINKS([host.h:config/$machine.h object.h:config/$obj_format.h])
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
to create the links.
