arm compiler preprocessor problem

Jon Peterson
Expert 1760 points


I am having a preprocessor problem with the ARM compiler. Probably something that I didn't specify right, but cannot find out what.

file A.h has a #define X 1 file B.c has an #if X ... #endif which ccsv5 shows in gray, ie not processed even though X has a non-zero value
B.pp shows A.h included before the #if...#endif sequence.
I am baffled by this behavior and have no idea what to try next.

btw: if i set A.h to #define X then I get a syntax error when the compiler processes the #if X ...#endif sequence in B.c; which is expected!
Any insight would be most appreciated. Thanks, Jon

    I am unable to reproduce this issue.  We need a test case which allows us to reproduce this behavior.  In this case we need to know the version of CCS, the version of compiler, and a project.

    Thanks and regards,

    George,

    If you give me a secure place, I will upload the entire workspace and give you more specifics about the problem. It's about 15MB in size.

    The entire workspace is not needed.  Just the project. Please follow these steps:

    • Right-click the project name and choose: Clean Project.  This removes object files etc.
    • Select File -> Export
    • In the next dialog select: General -> Archive File.  From there I think creating a .zip of your project is straightforward.
    • Back here on the forum, click on my name or Avatar
    • In the upper right click on: Start Conversation.  This brings up an interface for sending a private message to me.  You can attach the .zip file to the message.
    Please include the version number of both CCS and the compiler.
    Thanks and regards,
    -George

    To close this one out ... It turns out the user code has ...

    #if __TMS470__

    in it.  The symbol __TMS470__ is predefined by the compiler.  As already discussed in this thread, CCS does not display code around such preprocessor symbols correctly.

    Thanks and regards,
