[fpc-devel] fp IDE and gdbint on Debian Wheezy/testing

I believe Tomas is right saying that there are some symbols missing.
These funcions appear to be part of gcc's initialization/finalization
equivalent for shared objects (a quick search told me this). I once had
a similar issue with a symbol called `__dso_handle`, the fix for it was
to declare the symbol (as there was apparantly noone using it, but a
linker expecting it).

If I were you, I would try to declare these to functions; but I can give
you no garanties that it will help you in any way:

    Procedure _init; cdecl; public name '_init';

    Procedure _fini; cdecl; public name '_fini';

Hope it helps.

BTW: Is this behaviour the same with gcc < version 4.6 insalled?

Events don't necessarily happen in chronological order; yet somehow they do persist to happen. Sometime.
