Problem compiling project

[Joerg-SH]

Hello,
I use the last Chibistudio, works great!

I found this http://www.wheeze.plus.com/RPi_and_STM32F4DISCOVERY/

I think is based on a older Version of chibios.

Compiling stops with

Description Resource Path Location Type
fatal error: usb_cdc.h: No such file or directory usbcfg.c /ARMCM4-STM32F407-DISCOVERY-PI line 23 C/C++ Problem

I can´t find usb_cdc.h in the directories. So I think something changes???

Regards

Joerg

The USB stuff has been changed with version 2.6. It's correct that there's no usb_cdc.h file anymore. Take a look at the demos to see how it's done now (The code itself changed too [slightly]).

Ok I try to add code to a actual sample.

In code chrtclib.c is needed so I add "#include "chrtclib.h"" to main.c

I get compile error (see picture)

You need to enable the RTC driver in halconf.h.

I think I did?

/**
* @brief Enables the RTC subsystem.
*/
#if !defined(HAL_USE_RTC) || defined(__DOXYGEN__)
#define HAL_USE_RTC TRUE
#endif

What ChibiOS version are you using?

The one downloaded with Chibistudio (latest)

Have you included chrtclib.c in your Makefile?

Code: Select all

CSRC += $(CHIBIOS)/os/various/chrtclib.c

[Joerg-SH]

Thats was it, thanks a lot.

There is still a warning

main.c: In function 'Thread1':
main.c:276:1: warning: no return statement in function returning non-void [-Wreturn-type]

was before my changes to.


Is it possible to say eclipse to save all changed files before compile?

Hi,

That warning is known ad accepted, you can suppress that by putting a "return 0" at the end but doing so the Keil and IAR compiler would start complaining about unreachable code.

Being 2 compilers vs 1 compiler Keil and IAR win and the warning using GCC has to stay.
