The help page states this: This package was done with the following versions of GNU tools: * automake 1.9.4 * autoconf 2.59 * libtool 1.5.12 Apparently, Gambas does not compile with libtool >= 2.0. However my libtool is this: libtool 2.2.6a-1 And it compiles fine, so maybe this page needs updating? Regards Richard
