Hello! It seems that the AC_LIB_FROMPACKAGE macro from the havelib module can be used at most twice for a given package name. The following works:
AC_INIT([foobar], [0.1], [t...@example.com]) AC_CONFIG_MACRO_DIR([.]) AC_LIB_FROMPACKAGE([a], [libfoo]) AC_LIB_FROMPACKAGE([b], [libfoo]) But when I add the line AC_LIB_FROMPACKAGE([c], [libfoo]) I get the following error: $ autoreconf /usr/bin/m4:configure.ac:6: Warning: excess arguments to builtin `define' ignored autom4te: /usr/bin/m4 failed with exit status: 1 /usr/bin/m4:configure.ac:6: Warning: excess arguments to builtin `define' ignored autom4te: /usr/bin/m4 failed with exit status: 1 autoreconf: /usr/bin/autoconf failed with exit status: 1 Martin
