--- Comment #2 from Keith Marshall <keith.marshall at mailinator dot com> --- (In reply to Eric Botcazou from comment #1) > Look into the compilation log, there must be an error reported in this case. There is not. I see records of (successful) ar commands to build the static libraries, but no evidence at all of even any attempt to build shared; the build was configured with --enable-shared, and even explicit --enable-shared=libada makes no difference ... no shared Ada libraries are built, while shared libraries for C, C++, Fortran, ObjC, and other supporting components are.
