[davorin]

And the error messages you get?


I don't have any codewarrior stuff luckily...happy with gcc tools (o;

Link Error :multiply-defined:'OSMapTbl' in ucos_ii.o
Previously defined in os_core.o


Like this , there are many link error .

 

[davorin]

Like it says..."OSMapTbl" has been defined more than once...

Check for include files containing this definition...or the .c source file...

Maybe you´re including include-files in codewarrior as well?
Never worked with it though, prefer console type development with gcc (o;

 

[Davis]

Two possible reasons:

1. multiple definitions on variable "OSMapTbl"
2. recursively including header file in other header files. You can prevent from such case by using "#ifndef xxxx" to enclose the whole header file. For example:

#ifndef __header_file_name__
#define __header_file_name__

// header file contents

#endif

Ther could probably be 2 reasons - either Ucos or its port has modified or port has the problem .
Jean used one include file for all sources . For referred files memory will be defined in place , for refferring files 'extern' will be added in front memory declaration . This is described in his book . Check whether it is the case in your port .
