Aquileo | #1015 cast info imported incorrectly in SWIG_InitializeModule

Wed, 27 Aug 2025 20:27:45 -0000

c840bb728a886fd8b9a9f241c2d2b603f0e7a91b changed this code to make type casting threadsafe.

It's hard to be sure without having a reproducer, but it looks like the problem may still exist as cast->type is still only updated here if (type == swig_module.type_initial[i]).

Aquileo | #1166 [ruby] mixed case module names not handled correctly

Tue, 17 Jun 2025 04:36:12 -0000

We're still generating the same code AFAICS.

Retesting though I found it does actually work provided you use consistent naming:

$ RUBY=ruby3.2
$ echo '%module OpenBabel' > test.i
$ swig -ruby test.i
$ g++ -shared -fPIC \
  -I"`$RUBY -r rbconfig -e 'puts(RbConfig::CONFIG["rubyhdrdir"] || "")'`" \
  -I"`$RUBY -r rbconfig -e 'puts(RbConfig::CONFIG["rubyarchhdrdir"] || "")'`" \
  -o OpenBabel.so test_wrap.c
$ $RUBY -I. -e 'require "OpenBabel"'
$

So if you use %module OpenBabel then you need to name the shared object OpenBabel.so and load it with require "OpenBabel". That naming doesn't match Ruby conventions, but it is what was requested and does seem to work if applied consistently.

Still really needs input (and ideally a patch) from a Ruby person.
