After several (now solved) problems, I still have one last issue to fix to finally get wxWdgets and code::blocks work together.
When I try to build a wxWidget project, I get this error message :
"The procedure entry point__gxx_personality_v0 could not be located in the dynamic link library libstdc++-6.dll. "
I tried to reinstall minGW. I also tried to build, compile and run other types of c++ projects to see if the problem was still there and it wasn't. It really seems to be affecting only wxWidget projects.
Thank you for your help
----EDIT----
It seems that it comes from a previous Qt installation. I removed Qt from the path and renamed the old libstdc++-6.dll in the qt's directory. It still doesn't work.....
