I read somewhere on this forums that try-catch was supported, but when I try to compile with C++ exceptions enabled, I get the following link errors:
| Code: |

Someone knows the cause of the problem? |

I've gotten exceptions working before, but I can't immediately see anything really wrong with your command lines.
Try adding -lstdc++ to the LIBS variable in the makefile? |

| Thanks, that was the problem, libstdc++ missing in the makefile! (the sample I used as a starting point was originally in C, not C++) |
