  • 1.  Trace of XL C Preprocessor input

    Posted 06/26/23 10:57 AM 
    Using XL C on z/OS V2R5. I've got a set of #ifdefs in a header file that are not giving me the results I expect. I know on other compilers I've used in the past that there were options to output all input statements showing the #ifdefs and how the logic was processed. I need the same thing for the XL C compiler, but can not seem to find the proper options. I tried PPONLY, but it only showed the output after preprocessing it does not show the #ifdefs, which I need to see how the logic is getting executed.

    hi Si Yuan, 

    We have posted a response to the OP in the IBM-MAIN listserv, and here's what we wrote:

    You can use the SKIPSRC(SHOW) option along with any listing option (Ex. SOURCE) 
    to show the portions of the files. The EXPMAC option is also helpful to see 
    macro expansions.

    @Eric Erickson , there's a community space for the XL C/C++ on z/OS here:  LINK

    Feel free to browse and post any questions you may have about the compiler.  Thanks.

    Linda, 

    Is that a better place to discuss XL c related problems (like the one I just posted).

    hi Eric,

    Do you mean, compared to this forum (hosted under IBM Power Community)?    If you are developing software for zOS then yes, it is better to post XL C related questions in that community  (which is hosted on IBM Z and LinuxOne Community).

    thanks

    Linda, 

    Yes and thanks. This was the first forum I found on the community that seemed to deal with XL C. So I'll move stuff over there. 

    Thanks
