Trouble making extensions on windows

Hi, I’m using ruby192 and had a hard time trying to build my own c++ rb
I installed the DevKit and my extconf.rb generated makefile seems to
have no problem, but I got some ‘undefined reference’ build error that
cannot find ‘_Unwind_Resume’ and ‘__gxx_personality_v0’.
I don’t know what is that about, yet I can successfully build a static
library with same cpp files and same libraries in code blocks with the
same compiler, so… what exactly should I do now to make my extension

best regards

I solved the problem myself by rebuilding all *.a files and passed

perhaps you were using different compilers for the various builds?
