[Chicken-users] swig and c++ and stuff

[Tony Sidaway]

I tried a big SWIG wrap on part of a C++ library.  This generated a
.cxx wrap file and a .scm file.

The build sequence I'm using is this:

      $(CHICKEN) tvision.scm -output-file otvision.c
       $(CXX) --shared otvision.c tvision_wrap.cxx -o tvision.so
`rhtv-config --include` `rhtv-config --cppflags` `rhtv-config
--dir-libs` `rhtv-config --dlibs` -lchicken

This seems to build to a tvision.so file, but when I install that and
(use tvision), I get this:


ersion 2.524 - linux-unix-gnu-x86 - [ libffi dload ptables applyhook cmake ]

Error: (load) unable to load compiled module

       Call history:

       <syntax>                (use tvision)
       <syntax>                (##core#require-extension (quote tvision))
       <syntax>                (begin (begin (##sys#require (quote
tvision))) (##core#undefined))
       <syntax>                (begin (##sys#require (quote tvision)))
       <syntax>                (##sys#require (quote tvision))
       <syntax>                (quote tvision)
       <syntax>                (##core#undefined)
       <eval>          (##sys#require (quote tvision)) <--

I'm a bit new to Swig wraps. Is this a common problem? If so, what
have I done wrong?
