How do I check for the presence of Berkeley DB 4.x libraries within a configure.in (autoconf) file? I found the following m4 macro file: http://ac-archive.sourceforge.net/Installed_Packages/ax_path_bdb.html So I add it to a file called 'acinclude.m4' in the root dir of my source tree, and add the following lines to configure.in: # check for Berkeley DB >= 4 AX_PATH_BDB([4], [LIBS="$BDB_LIBS $LIBS" LDFLAGS="$BDB_LDFLAGS $LDFLAGS" CPPFLAGS="$CPPFLAGS $BDB_CPPFLAGS" ]) When I do this, it's as if autoconf starts failing in seemingly unrelated ways, possibly forgetting it's "core" macros: ... Running autoconf ... configure.in:13: error: possibly undefined macro: dnl If this token and others are legitimate, please use m4_pattern_allow. See the Autoconf documentation. configure:5421: error: possibly undefined macro: AS_VAR_PUSHDEF configure:5430: error: possibly undefined macro: AC_SEARCH_LIBS configure:5447: error: possibly undefined macro: AS_VAR_POPDEF ... wtf? I also see, ... ./configure: line 5416: syntax error near unexpected token `$HEADER_VERSION,ge,4,' ./configure: line 5416: ` AX_COMPARE_VERSION($HEADER_VERSION,ge,4,' ... PS- I'm doing this for http://gnewsuck.sf.net/, so if anyone does have time to help me out with this autoconf stuff (and wants to try it out themselves), all the source code is very freely available under the GPL. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
