--- Comment #6 from Keith Marshall <keith.marshall at mailinator dot com> --- (In reply to Keith Marshall from comment #5) > ... a clean configure and build does now produce: > > gcc/ada/rts/libgnarl-6.dll > gcc/ada/rts/libgnat-6.dll > > but there are no accompanying import libraries, (as there are for other > DLLs, produced for other languages in the GCC suite). Definitely an > improvement, but perhaps not quite the entire solution. Looking in the build log, (i.e. output from 'make 2>&1 | tee build.log'), I now see the commands which create these DLLs; in both cases, they invoke: mingw32-gcc -shared -shared-libgcc ... which is correct, (although -static-libgcc may be safer); however, both commands also include the -Wl,-soname,<dllname> linker option, which is wrong. AIUI, that option is applicable only for building ELF shared objects, but we are creating a PECOFF shared object; in this case, the preferred option would be the PECOFF linker's -Wl,--out-implib,<implibname> option, (and we would typically omit the DLL version suffix), such that we would produce: gcc/ada/rts/libgnarl.dll.a gcc/ada/rts/libgnat.dll.a to accompany: gcc/ada/rts/libgnarl-6.dll gcc/ada/rts/libgnat-6.dll
