Error under Windows/JRuby #2

Open arvicco opened 13 years ago

arvicco commented 13 years ago

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 13 years ago

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

arvicco commented 13 years ago

Reported this upstream: https://github.com/msgpack/msgpack/issues/53

postmodern commented 13 years ago

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