Link error L1822 + uCOS-II

[nicolas]

Hello,

I use codewarrior with a card with HC12 (mc9s12dt256).
I try to use uCOS-II on this card. For the moment, I try to compile the test file of uCOS for HC12. I try to compile it in codewarrior and view the results in the simulator of codewarrior.

My problem is the next :
- I have add the .h and the .c of uCOS in the lib folder of codewarrior
- I have not modify the test file
- When I compile the file, I have a lot of link errors L1822.
The errors are :
Link error : L1822 : Symbol OSInit in file C:\prj\test.c.o is undefined.

Someone can help me, because I search since 5 days and I don't progress.
Thanks for your help.

Salut Nico,

Here are my two pence worth.

Your LINKER error means that you have included the new C-file properly in your test.c.

However, a symbol (= variable, array, constant... whatever) from uCOS is declared in its files but is not declared in test.c.

From the name of the symbol, I guess the function "OSInit" prototype need to be added as an extern in test.c for the LINKER to see the reference between the two files...

May be...

Bonne Chance,

Alban.
