Re: trying to build a DLL on Windows 7 gcc using 3rd party libraries

for the record - with the 32 bit libraries and "__cdec" defined for al functions, all works fine.

Got it and thanks. Downloading the 32 bit version when the server comes back up. Will notify all of the results. Hoping for sucess.

If the "firebird" means the following :

http://www.firebirdsql.org/en/firebird-2-5-1/

then there shouldn't be any mistake about what one has
downloaded and what not...

I downloaded both the 32-bit and 64-bit ZIP-packages and
looked if my 'i586-mingw32' target binutils could handle
these files. The result was :

- the 32-bit 'fbclient_ms.lib' could be viewed nicely with
  'nm', 'objdump' etc.

- the 64-bit 'fbclient_ms.lib' could not be viewed with
  'nm', 'objdump' etc.

Seemingly my GNU binutils for MinGW host/target were too old :

C:\opt\firebird64\lib>\opt\cross\i586-mingw32\bin\objdump --version
GNU objdump (Linux/GNU Binutils) 2.17.50.0.16.20070511

Generally I'm not aware of the 64-bit MinGW situation,
using the 32-bit 'Firebird-2.5.1.26351-0_Win32.zip' or
some earlier version could work with the 32-bit MinGW
tools, I think...
