I'm trying to test the hello world example included in femtoOS 9.22
I'm using AVR studio and winAVR
i've read the readme text file and followed the part entitled "WINDOWS WITH WINAVR AND AVR STUDIO"
installed the script, opened a new project in AVRstudio and added femtoOS_headers folder ,femtoOS_source folder and from femtoOS_devices,added ATmega8.asm
then added the 2 files (hellow world.c and config_application.h) generated in the IDE folder after running the script
when I build the project, the following error is generated:
Error 1 #elif with no expression E:\CBBS\GccApplication1\GccApplication1\femtoos_check.h 104 6 GccApplication1
by replacing line 104 in check.h to "#elif (1==1)"
but after that the following errors are generated:
Error 3 variable 'pxTCBlist' must be const in order to be put into read-only section by means of '__attribute__((progmem))' E:\CBBS\GccApplication1\GccApplication1\femtoos_shared.c 495 16 GccApplication1
Error 4 variable 'pxTDBlist' must be const in order to be put into read-only section by means of '__attribute__((progmem))' E:\CBBS\GccApplication1\GccApplication1\femtoos_shared.c 531 32 GccApplication1
how can I solve it?
thanks
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I assume there was a problem with installing winavr with avrstudio as after re-installing them and adding the proper files to the project it compiles successfully (when excluding femtoos_app.c)
thank you for your quick response

Sorry i noticed this so late, better start a new thread next time. From the errors it seems that the compiler cannot find the sources. Is the question still valid or did you already solve it?

Please tell me the version you are using. I assume you are on avrStudio under windows?
This is unneeded in version 9.22 for it has been corrected. The 'patch' was for version 9.20.
It's Atmel studio 6, I think it's version 4.6.1
yes i use it under windows
anyway, It's solved

hi myself bharath just know started to work on femto os and i'm getting an error in the example program shown iin the start page the program i have written is
include "femtoos_code.h"
static Tuint08 speed=0;
const Tchar HelloWorldStr[]="hello World";
if (preTaskDefined(Display))
void appLoop_Display(void)
{ speed = 64;
while (true)
{ Tuint08 uiCharCount;
Tchar cChar;
for (uiCharCount = 0; uiCharCount<12; uiCharCount++)
{ cChar = portFlashReadByte(Tchar, HelloWorldStr[uiCharCount]);
devLedPORT = ~cChar;
taskDelayFromNow( ((Tuint16)speed)*4 + 64 );
devLedPORT = 0xFF;
taskDelayFromNow(64); }
taskDelayFromNow(2000); } }
endif
and the error i'm getting

anyone will please help on this
sorry if anything wrong
Sorry i noticed this so late, better start a new thread next time. From the errors it seems that the compiler cannot find the sources. Is the question still valid or did you already solve it?
