Well, the subject says it all. The following example exposes the bug:
$ cat > configure.ac <<'END'
AC_INIT([x], [0])
AM_INIT_AUTOMAKE([foreign])
AC_CONFIG_FILES([Makefile])
END
$ cat > Makefile.am <<'END'
java_JAVA = foo.java
END
$ aclocal
$ automake -a
configure.ac:2: installing `./install-sh'
configure.ac:2: installing `./missing'
$ grep '^ *javadir' Makefile.in || echo 'javadir undefined!'
javadir undefined!
I can suggest three possibilities to fix this issue:
1. Define `javadir' to `$(pkgdatadir)/java' in lib/am/java.am.
2. Define `javadir' and `pkgjavadir' to respectively to `$(datadir)/java'
and `$(pkgdatadir)/java' in `lib/am/java.am', and add "pkgjava" to the
@prefixes passed to am_primary_prefixes() and am_install_var() calls
in handle_java() in automake.in.
3. Remove "java" from the @prefixes passed to the am_primary_prefixes()
and am_install_var() calls in handle_java() in automake.in.
In the first two cases, the Automake manual should be adjusted accordingly.
My preference lies with option 3. Opinions?
