Re: mkoctfile and linking newbie question

[roumbaba]

Ok I have found a way around:

The same command with the -v option display the gcc commands issued.
It turns out that my -l option gets called at compile (-c) time and not a
link time for some reason.
So now instead of using mkoctfile use system( ) with the correct gcc
arguments order.
