Linker Problem

Dr. Yehuda Singer
Expert 1240 points


Dear sir/Mrs.

We are workin on a project with the following configuration: 

1. Target machine: 6678.

2. Software tools 7.3.5.

3. C++ with exceptions.

4. BIOS6. 

The files are compiled successfully. THe linker gives error messages which are not comprehensive. for example: suppose we use a constant  X which is referenced by many modules. The error message saya that we have a redefinition problem.

On the other sie, if we refer to a variable using its namespace, the compiler finds that variable. The linker says that the variable is undefined.

Best regards,

Yehuda

    Please see if your diagnostics have an explanation at http://processors.wiki.ti.com/index.php/Category:Compiler_diagnostic_messages .  If not, then we need to see the exact text of the diagnostic.  

    Thanks and regards,

    -George

    As you see, it is not clear what is redefined etc. In addition, the map file include some undeffined symbols which are well define. We can see it in the editor when we put the mouse on.

    Best ergards,

    This is some kind of capture of the Problems window.  And, unfortunately, not a very useful one.  It seems that all the important parts got cut off.

    Instead, post the contents of the Console window.  The usual copy-n-paste operations should work.  That will show the linker diagnostics in full.

    Thanks and regards,

    DEar george, 

     The console message may revealthe project which is confidential. We have an NDA with TI. I would like to pass it via a conversation.

    Best regards,

    Yehuda
