Compiler problem unresolved

"..\USB/usb_serial_structs.h", line 65: error #20: identifier "tUSBDCDCDevice" is undefined
1 error detected in the compilation of "../EPGPackets.c".

tUSBDCDCDevice is defined in the TivaWare usblib/device/usbdcdc.h include file.

I.e. try adding the following to EPGPackets.c before the include of usb_serial_structs.h:

#include "usblib/device/usbdcdc.h"

Thank You for your help.

Inserting that line

#include "usblib/device/usbdcdc.h"  in EPGPackets.c caused a new error message to appear along with the original error message.

----------------------------------------------------------

Another file EPGMain.c has that same original error message.  I also tried inserting you suggested include line in EPGMain.c with the same results

That line might be necessary but not sufficient.  Id does not remove the original error message.

tLineCoding is defined in usblib/usbcdc.h

The #includes need to be arranged in the correct order so that tLineCoding and tUSBDCDCDevice are defined before they are used.

This is an example of the includes from a usb_serial_structs.c file which compiles:

#include <stdint.h>
#include <stdbool.h>
#include <usblib/usblib.h>
#include <usblib/usbcdc.h>
#include <usblib/usb-ids.h>
#include <usblib/device/usbdevice.h>
#include <usblib/device/usbdcdc.h>

#include "usb_serial_structs.h"

Progress...........................!!

Ordering the includes resolved the problem in EPGPackets.c

It did not however resolve that same error in EPGMain.c

Here is the include file ordering in EPGMain.c

---------------------------------------------------------------

#include <stdint.h>
#include <stdbool.h>
#include <usblib/usblib.h>
#include <usblib/usbcdc.h>
#include <usblib/usb-ids.h>
#include <usblib/device/usbdevice.h>
#include <usblib/device/usbdcdc.h>

#include "USB/usb_serial_structs.h"


//#include <stdint.h>
//#include <stdbool.h>

#include "inc/hw_nvic.h"
#include "inc/hw_types.h"

//#include "USB/usb_serial_structs.h"

//#include "driverlib/debug.h"
//#include "usblib/usblib.h"
//#include "usblib/usblibpriv.h"

//#include "usblib/device/usbdcdc.h"

#include "EPGConsts.h"
#include "EPGPackets.h"

#include "ICS/ICSLIO.H"

-------------------------------------

All the EPGxxxx and ICS/xxxxxx and USB/xxxxx reference files in my project.

When I configured this code I copy 3 files from the USB library into my project so can make changes to them (altering BUFFER_SIZE only) and keep them safe from USB library updates.  Because of this issue these files are not touched.

That is, almost certainly, a bad idea. It has every possibility of turning into a nightmare.

It would be far better would be to create a project specific version of the library.  Probably in a sub-directory with notes on the configuration changes made.

You should also ask why, if buffer size commonly varies, there is no mechanism to vary it w/o modifying the library. Is it an oversight on the part of the library builders (it is vendor supplied so that would not be unbelievable) or is the problem you are addressing better solved in a different fashion.

The compiler error I get it s the following:

That's where the nightmare starts.

Any suggestions as to where to look?

I'm going to be a little blunt here.  Have you tried searching? You should be able to find all the references (including the definition) with a grep search or your editor.  And if your current tools don't support this kind of search you are in need of ones that do. 

It's possible the identifier is built up using concatenation operators but that's a little obscure and not often justifiable.

Pure blasphemy here - have you considered - and/or tried - using Rev 9453 StellarisWare? That & earlier versions escaped much of the change & difficulty arising under the "rebrand."

Our small tech firm continues to use 9453 - with past LX4F (which vendor assures is TM4C equiv.) - and has escaped (thus far) any/all issues brought about by the, "rebrand."
