Hello evrybody, We use autotools for our build factory wich build programs under a lot of computers/OS, including mainframe. We succeeded compiling and linking executable (PGM) and static lib (BNDDIR) under OS400 / Pase witjout needing to dig down libtool, but the need to make shared lib (SRVPGM) forced me to make some modification in libtool.m4 to add support for os400 OS to get shaed lib possible and to get the right archive_cmds value Maybe there is an other way to add this kinf of support, by only modifying configure.ac but I didn't find out the trick. Are you interested by the stuff we made on OS400 ?
