Hello Angelo,
First, please subscribe to list before posting to it. Otherwise it can
be likely that a message gets unnecessary delayed or even deleted by
accident.
To your issue. Yes indeed the the failure-code seems to be a missing
DLL, or a wrong DLL with missing exports. I assume that not all
gcc-related DLL files are in your search path. You can try to use here
option '-static' to see, if it works without DLL files.
I hope I could help,
Kai
PS: Please subscribe to this list before replying, thanks.
