Hello! I have created configure.in that tests if libary libz.so exists with AC_CHECK_FILE (i don't want to search with funcion in AC_CHECK_LIB), then if it is found it also tests libz.so.1.2.3. Now I want to know if libary libz.so actualy points at libz.so.1.2.3 since there can be more version in the same dir. I tried with "test file1 - ef file2"; but i can't make it work or I don't know to write the correct syntax (I am new user of gnu autoconf). I would also like to know if there is any predefined macro or any exemple on the net of how to get or test libary version. thank you for any helpful reply! -- View this message in context: http://www.nabble.com/how-to-check-linked-libarys--tf2232993.html#a6189774 Sent from the Gnu - Autoconf - General forum at Nabble.com. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
