Switching to C6000 Code Generation Tools v7.0.4

Hello,

because I need packed structs (__attribute__((packed)) ), I tried to switch to the cg tools version 7.x. Installing them from the ccs4 update function worked fine, selecting the compiler in the project properties, too. But when I try to link my code (imported spiSample to CCS4), I get this error:

'Building target: spiSample.out'
'Invoking: Linker'

 rtdx64xplus.lib is available in C:/Programme/Texas Instruments/bios_5_41_02_14/packages/ti/rtdx/lib/c6000, so I don't understand the error... Do I need a new DSPBIOS that works with cgtools v7.x? Another way of helping me would be: Can I create a packed struct with the cgtools v6.x? Many thanks, Markus

    Hi Markus,

    You can try explicitly adding it to your project (-l option) and see if that helps.

    Not sure why it is not finding the file however since your search path is correct. I take it that the library is referenced in your command file?

    Hello,

     

    after a long break, I can go on here at last....

    I tried what you said but it didn't help. So I started sysinternals filemonitor and saw this:

    As you see in the first line, the linker immediately finds rtdx64xplus.lib. Strange that it complains... And it keeps searching in various directories. Line 43 lead me to the idea to copy/drag the lib into my project tree - that worked! Now the program compiles.

    So this is some kind of solution - but I don't like it. I shouldn't have to copy libs to my sources. In fact, I consider it a bug - do you agree?
