note syphilis Are you using the "MSI Installer" version of that distro ? According to [http://strawberryperl.com/releases.html|this page], it's SHA1 digest should be: <c> e67728ddd89777815271ac7416cff32653d387bf </c> Is that what you have ? (I get that SHA1 digest for the distro that I just downloaded - so that part looks fine to me.)<br>If you get a different SHA1 digest for the distro you downloaded then, either you've grabbed a different distro, or you've got a corrupted distro.<br><br>When I install that distro and run: <c> objdump -t C:/strawberry/perl/lib/CORE/libperl516.a >dump.txt </c> I get no errors ... so I'm thinking that you must be running a different objdump. Where is it coming from ? You need to run the objdump that's in C:/strawberry/c/bin ... so try: <c> C:/strawberry/c/bin/objdump -t C:/strawberry/perl/lib/CORE/libperl516.a >dump.txt </c> Does that make any difference for you ?<br>Finally, the various digests I get for libperl516.a are: <c> Enter the filename (full path): C:/strawberry/perl/lib/CORE/libperl516.a MD5: e53826b93afd80de2e44038da93e63ba SHA1: 68737f9536907c5a37833b94e26685a10d9c5ce0 SHA256: c66d4ad43a583304b800e22966de0ab5baa6000ccb956643559b8e76f62e84dc </c> Does that match what you get ? (No need to check all 3 - any one will do.) <br><br>Cheers,<br>Rob 1001132 1001148
