Trying to use ffi-msgpack on Windows (XP Pro SP3).

Ruby: jruby 1.6.1 (ruby-1.8.7-p330) (2011-04-12 85838f6) (Java HotSpot(TM) Client VM 1.6.0_20) [Windows XP-x86-java]
Gem: ffi-msgpack (0.2.0)
Msgpack lib: 0.5.4, built following instructions here: http://wiki.msgpack.org/display/MSGPACK/QuickStart+for+C+Language

On require 'ffi/msgpack', everything explodes with the following backtrace:

C:\Dev\p2\gate\clients>jruby --1.9 bin/swing_gui
LoadError: Could not open library 'msgpack' : The operation completed successfully.
. Could not open library 'msgpack.dll' : The operation completed successfully.

The thing is (if I get it right), it is looking for .dll, but msgpack project only builds .lib - which is on the path, of course, but it doesn't help :(

Ah yes, ffi gem is: ffi (1.0.7 java)

I would also report this to upstream msgpack. They need to build a proper DLL for Windows.

arvicco commented May 13, 2011

So, that .lib file that is built by msgpack is not usable via ffi?

arvicco commented May 13, 2011

Reported this upstream: msgpack/msgpack#53

It turns out that .lib files on Windows are analogous to .a static libraries on UNIX. So definitely not dynamically loadable by Windows.

Closed

Proper DLL is not built on Windows #53
