Hi,

I didn't get FXRuby (Ruby interface for FOX GUI Toolkit) available from
fxruby.sourceforge.net working on NetBSD 1.5.

At first I get a memory exhausted error, but when disabling optimations this do
not occures any longer.
But then I get a '/usr/lib/libstdc++.so.2: Undefined symbol "__vt_9exception"...' 
error when trying to load the shared library.

Perhaps a too old version of the stdc++ library?

Has anybody some hints?


Thanks in advance.

Stop.



Then if I remove the -O2 option from CFLAGS in Makefile it successfully compiles.

But when I try to require the fox library:

$ ruby -r fox -e "p 'test'"

the following exception is raised:

0: /usr/lib/libstdc++.so.2: Undefined symbol "__vt_9exception" (reloc type = 6, symnum = 934) - /usr/pkg/lib/ruby/1.6/i386-netbsd/fox.so (LoadError)

After changing some settings in the Makefile I got:

0: /usr/pkg/lib/ruby/1.6/i386-netbsd/fox.so: Undefined symbol "__sjthrow" (reloc type = 2, symnum = 39) - /usr/pkg/lib/ruby/1.6/i386-netbsd/fox.so (LoadError)
