Hello All,
I am having a terrible time during the link step. Here is my scenario:
[ul]
[li]I have written a program that only uses classes from the standard C++ library. It is a console based app.[/li]
[li]Now I want to bolt on a GUI front end to this thing, so I used VS 7.0 to build a simple GUI. [/li]
[li]Both programs compile, link, and execute just fine. [/li]
[li]Now I bring in my classes from the console app into the VS project[/li]
[li]I created a makefile to build everything, but I get tons of linker errors. I have the output below[/li]
[li]Microsoft seems to be a little smarter in building this thing because it can build it just fine. However, when I run it, it kicks off the command window and crashes immediately due to a failed ASSERT. The ASSERT comes from appcore.cpp.[/li]
[/ul]
Code: 
CWinApp::CWinApp(LPCTSTR lpszAppName)
{
if (lpszAppName != NULL)
		m_pszAppName = _tcsdup(lpszAppName);
	else
		m_pszAppName = NULL;

	// initialize CWinThread state
	AFX_MODULE_STATE* pModuleState = _AFX_CMDTARGET_GETSTATE();
	AFX_MODULE_THREAD_STATE* pThreadState = pModuleState->m_thread;
	ASSERT(AfxGetThread() == NULL);       //***** Fails here ***** AfxGetThread() is NOT NULL!!!!!!

... Continued


Here is the link errors I get when I use my makefile

Stop.

If I remove the 3 .objs (the console part) from the link step, then of course it's okay. But even if I ad just one back to the list of objs to link, it fails with this same error.

I know that the linker is giving me some clues about why the problem is happening &quot;defaultlib 'msvcrt.lib' conflicts with use of other libs; use /NODEFAULTLIB:library&quot;, but I just can't quite piece it all together to make sense. Can someone please help me out?



many many thanks,

Why are you using a make file? Why not just add your classes to the project and build it from the IDE?

Pete,
Yes I did that too. VS knows how to build it, but apparently not correctly because like I said when I run it, it kicks off a command window then crashes. The 2 programs run fine when built and run separately. It's when I try to build them all together into 1 exe that I get problems. I know it's something I'm doing wrong, but what?

The makefile is just an educational experience.

There is way to much code to post here, but maybe I can conjure up a test case to post. Actually trying to figure out a test case may help me solve the problem. :)

If you have any ideas, please let me know...


regards,


Barry

Barry, obviously you need to find out exactly what is causing the crash. Assuming that the build configuration is incorrect and therefore the cause of the crash is just not a good problem solving approach.

Are you executing it in debug mode? If so that should help you pinpoint the problem in seconds. If not you should be.

Yes, I am running in Debug mode and I do see where it crashes. As I stated above it happens on an ASSERT statement in appcore.cpp which is not my code. &quot;ASSERT(AfxGetThread() == NULL);&quot; The answer is not obvious (to me anyway) which is why I posted this message. I find it bizarre that it starts this command window. It is supposed to be a GUI application.

When that ASSERT stops the debugger, use the stack window to find the entry point from your code into that call. When you double click on the line in the stack window open the file and position the cursor on that line of code.

HEY!!! I finally figured it out! For some strange reason when I added my source files to the already existing project I lost the link option /SUBSYSTEM:WINDOWS So that explains why it was kicking off the command window, and then it would crash when my constructor called CWinApp. Makes sense now![smarty] Thanks for your help Pete!
