 Dear all,

 I am trying to move away from the VC++ and over to DMC++. I am having some
 trouble getting a clean build using the mySQL headers and library.  Has


 used these in this environment?  It may be something simple.  I am not


 This is new to me.  Thank you for your time.

Use coff2omf (see http://www.digitalmars.com/ctg/implib.html#coff2omf) to
convert the lib-file.

I have never used the mySQL library, but is the mySQLclient.lib an import
library and not a static library?  If it is an import library, then it is a
VC++ compatible library, and import libraries are usually not compatible
betweeen compilers.

Is there a mySQLclient.dll file included in the mySQL installation?  If so,
maybe it's possible to create a DMC compatible import library from the DLL
without involving the mySqlclient.lib.

Borland (now Inprise) has a program called IMPLIB.EXE that takes a DLL (not
an existing import library) and creates a Borland C++ compatible import
library file.   I hardly use Borland any more, but  IMPLIB was a godsend if
I was given VC++ lib files (which were unusable) and the DLL file.  Maybe
DMC++ has such an app to create import library files that are compatible for
DMC++ (if not, maybe Walter will consider making one :)).

Yes, the binary formats are incompatible. Those of DMC and Borland are 
left-overs of the DOS days...

Anyway, if your library is available as DLL, you should use the import 
librarian, which you get in an utility package here:

http://www.digitalmars.com/download/dmcpp.html

Agree to the agreement, then scroll to "Basic Utilities"... How could 
you live without them?

Documentation is here:

http://www.digitalmars.com/ctg/implib.html

However, if it isn't a DLL, and you don't have or can't fix the source 
to compile on DMC, the last thing you can try is to use the binary 
conversion routine, coff2omf. I have an old one from dm812util.zip, but 
using it gives very whacky results. It's not what you should generally 
do. It seems that Walter doesn't offer it for free download anymore, but 
tries to sell it for a fair amount of green pieces of paper (which are 
not unhappy even without being moved back and forth :> ). Here:

http://www.digitalmars.com/eup.html

So first, try recompiling the library itself with DMC, and post the 
specific problems you can't handle here again. I guess original authors 
would also appreciate a fixed version. See these for more information:

http://www.digitalmars.com/ctg/switchtodigitalmars.html
http://www.digitalmars.com/ctg/ctgPorting.html

I've also got some trouble porting MiniFMOD, and the problem is with 
inline assembly, but i forgot to post it. :(
