Hello I've got a quick question about the AC_CHECK_LIB macro: What directories does this macro search in?? is it just standard ones (like /usr/lib) or will it also search directories specifed by certain environment variables and/or script variables (such as LIBS) It seems to me that it only searches standard libraries, but Im not entierly sure, and the documentation isnt clear. Ive tried passing $LIBS to AC_CHECK_LIB as part of the 'other libraries' variable, but that didnt seem to work either can you pass -L flags to AC_CHECK_LIBS?? I know you can pass -l flags so I would assume so. I was also wondering where this macro is defined. Doing a quick `grep 'AC_CHECK_LIB' *` didnt turn up its definition Any ideas? Thanks a bunch -Paul Wighton
