Hi, The included documentation (INSTALL/) does not mention what version of gnat is required to build gnat for 3.0. I found an RPM on an auxiliary RedHat 7.1 disk (gnat-devel-3.13p-4.i386.rpm). It contained a gnatgcc that says: gnatgcc -dumpversion 2.8.1 Anyone know if this will do for a 3.0 to 3.0.4 build? Thanks! kevin
