I may have found the problem here, but I am in Microsoft land and am not sure of myself.
It would appear that the version of gcc that I installed is 32 bit - the name is MINGW32.
It would appear that the version of the firebird software is 64 bit so the libraries are 64 bit.
This is probably why the link does not deal well with the libraries.
In Unix I could be sure as I could say "file gcc.exe" ....
I will make sure that the two are compabible and try again.
Very confused - if anyone can tell me the MS equivalent of Unix/Linux "file", that would help a lot.
Using 'objdump' with different options could be what you want.
For instance :
C:\opt\cross\i586-mingw32\wbin>dir
