Cygwin List -

I am resending this message as I have not yet had a response from the 
orignal post. I'm hoping that someone can get me started either with a HOWTO 
or some simple instructions.

Thanks!

Chris

Subject: New User: including a third party DLL and using -mno-cygwin

Gang -

I'm trying to compile a program which is dependent on a vendor supplied dll.
I have a vendor supplied .H file which is #included in my program. After
trying various command line options, I got the following to work:

---------cut here------------cut here-----------cut here-----------

gcc -I. m:/fs75/bin/client/winx86/psmsg.dll hello_psft.c

---------cut here------------cut here-----------cut here-----------

The program runs, except that it never exits. (I'm not too worried about
this, I suppose I'll figure out why later. I have to use <ctrl>-<c> in the
CYGWIN bash window.)

So then I want to run this outside of the CYGWIN bash window. I realize that
I need to use the option -mno-cygwin. So I tried various iterations of the
following:

---------cut here------------cut here-----------cut here-----------

gcc -I. -mno-cygwin m:/fs75/bin/client/winx86/psmsg.dll hello_psft.c

---------cut here------------cut here-----------cut here-----------

And I usually end up with something like:

---------cut here------------cut here-----------cut here-----------

/cygdrive/c/DOCUME~1/JHEFFE~1/LOCALS~1/Temp/ccQOStJ5.o.text+0xd7):hello_psft.c:
undefined reference to `PSMsgConnect AT 16'

collect2: ld returned 1 exit status

---------cut here------------cut here-----------cut here-----------

I've also tried to get GCC to recognize the DLL by using the -L or the -l
options without success. I've tried moving the -mno-cygwin option around the
command line, without success.

Can someone illuminate what I am doing wrong? Basically, I'm trying to get
this to run on a Win32 program without any need for the end user to have
CYGWIN installed on their machine. I don't have access to the source code
inside "psmsg.dll". How do I link my program to this DLL successfully? (And
if anyone knows why the program doesn't exit inside the CYGWIN bash shell,
that would be a bonus answer that would be appreciated.)

Also, if anyone knows of any tutorials or HOW-TOs for cygwin and programming
on Win32, that would be greatly appreciated.

Thanks!

Chris

Here is a copy of the source code:

---------cut here------------cut here-----------cut here-----------

#include <string.h>
#include <stdio.h>
#include <psmsgapi.h>

void PrintError(char *);

PSMSGHANDLE     hCtx;

main()
{

PSOPERATOR      Opr;
int             Result;
int		nReplyOption;

!/* Setup the Operator ID and Password */
strcpy(Opr.szOprId, "JHEFFERM");
strcpy(Opr.szOprPswd, "JHEFFERM");

!/* Connect to the application server for the database we're going against
*/
PSMsgConnect(PSMSG_APIVERSION, "10.102.88.159:8003", &Opr, &hCtx);

!/* Setup the activity and message definition */
PSMsgStartMessage(hCtx, "Message Agent Example", "CRM_COUNTRY_ADD", 0);

!/* Populate each of the fields in the message */
PSMsgSetField(hCtx, "COUNTRY", "CRM");

!/* Attempt to process the message */
PSMsgProcessMessage(hCtx, &nReplyOption);

!/* Disconnect from the database */
PSMsgDisconnect(hCtx);
printf("Success\n");

return(0);

}

/* Print an error and die */
void            PrintError(char *pStr)
{

printf("%s\n", pStr);
PSMsgDisconnect(hCtx);

//exit(1);

}
