[M3devel] new problem linking on NT386

Tue May 6 04:08:29 CEST 2008

Jay:

No, I am using the -gui option in the m3makefile.  It is a windows gui application.

Here is the output of the command you suggested:

As you can see, I have an
   _main  and a
   _Main_M3

Not sure what you mean by saying I am missing hand.obj.  I have rebuilt everything using latest CVS update.  Please elaborate.

Randy

Sounds like you missed the "gui" switch on the cm3 command line
or in the m3makefile -- in the m3makefile really.
Putting it on the command line imho is only reasonable for those
simple cases that don't have an m3makefile

 link -dump -symbols NT386\_m3main.obj | findstr /i main 

?
I expect you will have main or wmain, but not WinMain or wWinMain.

Is this meant to be a gui app or a command line app?
If it is meant to be a command line, then the problem is something else.
  And I don't even want to explain..
Can you send me the source?

Also you are missing hand.obj here, so you don't have the potential pixmap fix.

I've rebuild my cm3 system using the latest sources.

I am now having a failure linking certain programs that used to build without problems.

I've listed the linker output from one of the programs below.  The issue seems to be an unresolved external symbol _WinMain at 16 .

Any ideas on what has changed and how to get this working again?
