Steps to reproduce: - Get any recent version of MingMW (2003 or later) - Download & extract GNU GMP 4.1.4 tarball - ./configure --disable-static --enable-shared - make The resulting libgmp-3.dll seems to be an invalid WIN32 PE file. Attempts to link an app with this DLL cause the process to fail to load. Attempting LoadLibrary() causes an access violation (possibly in the MinGW crt startup code - unsure). A workaround is to use ld.exe from an old MinGW. The ld.exe from binutils-2.13.90-20021006-2.tar.gz works great & produces a usable DLL. The ld.exe from binutils- 2.13.90-20030111-1.tar.gz does NOT work nor do any later versions. Juro Bystricky discovered that the issue is something to do with relocating the DLL to something other than its preferred base address.

It's libtool with default options as far as I know.... ---------------------------------------------------------------------- Comment By: Danny Smith (dannysmith) Date: 2005-04-06 16:53 Message: Logged In: YES user_id=11494 What is the command line to build the dll?
