Hi,
I'm trying to compile the PC demo program that comes with FreeRTOS.org. When I make, the linker has errors, the build log is as follows:
cd D:\FreeRTOS\Demo\PC
wmake -f D:\FreeRTOS\Demo\PC\rtosdemo.mk -h -e D:\FreeRTOS\Demo\PC\rtosdemo.exe
wcc ..\..\SOURCE\croutine.c -i=D:\WATCOM\h;..\common\include;..\..\source\include;..\..\source\portable\owatcom\16bitdos\common;. -w4 -e25 -za -dOPEN_WATCOM_INDUSTRIAL_PC_PORT -dUSE_STDIO -j -zq -otexan -s -fpc -zu -1 -bt=dos -ml
Error(E14): Cannot execute (wcc): No such file or directory
Error(E42): Last command making (D:\FreeRTOS\Demo\PC\croutine.obj) returned a bad status
Error(E02): Make execution terminated
Execution complete


It can't find WCC even though my environment variable 'path' include (amongst others):
D:\WATCOM\BINNT;D:\WATCOM\BINW

I'm using XP, OpenWatcom 1.6, FreeRTOS 4.2.0
Help?
Sam

I have only compiled the project using the Open Watcom IDE, never the command line. However, I do have wcc in in my \WATCOM\binnt directory.

I am using OW V1.4 - could it be that V1.6 has changed the name of the executable?

Regards.

Hi,
thanks for the reply.
I am compiling with the IDE btw, the error is from the build log.
I only have a file names wcc386.exe in my binnt directory and this seems to be the problem.
I have renamed wcc386.exe to wcc.exe in the same directory. I don't think this is the correct solution, I think possibly the compiler must have a setting to make it look for wcc386 although I haven't found it yet. I also had to rename wcc386.dll to wccd.dll.
I also changed my Memory model switches to Pentium (Options->Linker switches->C compiler switches->memory model switches)
Unfortunately it still will not compile as it is looking for libraries in locations that don't exist. I have a feeling the settings are all incorrect.

I should try reinstalling OW. It sounds to me that you have installed the wrong components. Maybe just the 32bit components. You need to the 16bit components.

Works!! Now it compiles with no problems, thanks.
When I run the .exe under a DOS window in XP however, I get the following errors:

Is there a simple 'hello world' program written out there to start with?

Thanks again,
Sam

Success!!
I used wmake from the DOS prompt. Seems to work fine now. This is good as I will be developing under DOS anyway.
Thanks,

Cool. Don't forget the SET NO87=1 environment variable.
