makefile - Can I define an install rule / install hook in configure.ac -


say there bunch of (e.g. 200) modules depend on core module. using autotools.

the core module installs core.m4 file dependents use various things.

all dependents have lines in install-data-local rule generate scripts , install them, e.g. 

core_stuffdir=$(prefix)/share/core/stuff/  install-data-local:         generate-stuff stuff.xml         test -d $(destdir)$(core_stuffdir) || mkdir $(destdir)$(core_stuffdir)         stuff=`xmllint --xpath '//stuff[@install="yes"]/@name' stuff.xml`; \             $(install_data) $$stuff $(destdir)$(core_stuffdir); \             rm $$stuff         …         $(install_data) other-module-specific-stuff …         …

i remove 5 lines redundantly duplicated on ~200 files, , instead define lines in core.m4. dependents should able somevar: somevalue (or short, @ worst one-line thing in install-data-local) , have lines executed during make install.

is there nice way define these lines in core.m4 , make them available makefile.am? can't find similar examples on net.

the solution can think of m4 spits out shell script can call install-data-local, i'm not sure that's best (or autotoolish) way.

alternatively, there simple way distribute automake fragment.am file core module? (this seems way e.g. python compilation rules defined.)

after digging, found http://thread.gmane.org/gmane.comp.sysutils.automake.general/5704/focus=5708 has solution similar problem (i couldn't ac_config_files solution mentioned there work).

so core.m4 defines core_mkinclude:

ac_defun([core_mkinclude], [   ac_subst_file(core_include)   core_include=$srcdir/core_include.am    cat >$srcdir/core_include.am <<eof  core_stuffdir=\$(prefix)/share/core/stuff/ install-stuff:         generate-stuff stuff.xml         test -d \$(destdir)\$(core_stuffdir) || mkdir \$(destdir)\$(core_stuffdir)         stuff=\`xmllint --xpath '//stuff@<:@@install="yes"@:>@/@name' stuff.xml`; \\                 \$(install_data) \$\$stuff \$(destdir)\$(core_stuffdir); \\                 rm \$\$stuff  eof  ])

ie. goal printed file core_include.am, , has own name. each module's configure.ac calls core_mkinclude, , each makefile.am has

@core_include@ install-data-local: install-stuff

an improvement @ least.
