Hello Richard, C/Invoke is another library whose name i forget.
Thanks a lot. Though the haskell wiki [0] claims that libffi works on x64.
i don't know, just read yesterday on Lua list:
A question for Fabio: what are the issues with Alien for 64-bit Windows?
I can answer part of that. Libffi [1] (the C library on top of which Alien is built) has no support for 64-bit windows. More specifically there is a need for some runtime generated glue code (mainly for callbacks), and assembler support for x64 is very poor so far (many Visual C++ compilers come without assembler and/or lack support for inline asm). Python and Java (in the JNA package) have their own port of libffi specifically for x64. However I never managed to compile any of these two for Alien (usually because of the lack of assembler). I tried all this about a year ago, so things may have changed since then. [1] http://sourceware.org/libffi/ -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
