  • [SOLVED] SES v7.32 analyze fails where v7.30 succeeds

    Using clang-tidy to analyze code is a great feature. Unfortunately, analyze doesn't work on my codebase (a mix of C/C++) when using v7.32. Compared to v7.30, SES v7.32 adds three new switches used to run clang-tidy and modifies one:

    Source Code

    1. // switches added by v7.32
    2. -U__clang__
    3. -U__SEGGER_CC__
    4. -D__GNUC__
    6. // switches modified by v7.32
    7. // v7.30 used -mthread-model single
    8. -Xclang -mthread-model
    9. -Xclang single

    The failure is always in the same header:

    Source Code

    1. // error on line 1723 of header <functional>
    2. template<class _Fp, class _Alloc, class _Rp, class ..._ArgTypes>
    3. const void*
    4. __func<_Fp, _Alloc, _Rp(_ArgTypes...)>::target(const type_info& __ti) const _NOEXCEPT
    5. {
    6. if (__ti == typeid(_Fp)) // <<< error on this line
    7. return &__f_.__target();
    8. return (const void*)0;
    9. }
    11. // console reports the following
    12. '__GNUC__' macro redefined [clang-diagnostic-macro-redefined]
    13. use of typeid requires -frtti [clang-diagnostic-error]
    Display All
    Has anyone else seen this and got ideas for a workaround?

    Thanks,

  • Hello Adam,

    Thank you for your inquiry.
    The GNUC define seems duplicate. We will check if this can be removed again.

    Regarding the error you see. It is possible that an updated clang-tidy reacts differently to the same source.
    As a workaround you can set additional options in project options under Code->Code Analyzer.

    In this case as the error states simply add -frtti.

    Best regards,
    Nino

  • HI Nino,

    Options added under Code > Code Analyzer > Analyze Command Options C++ aren't applied to the Analyze command unless a new command is defined in Code > Code Analyzer > Analyze Command.

    I defined a new command that looks much the same as the built-in, removing the macro -D__GNUC__ and adding two new macros (see example below). Analyze is working for me again.


    Thanks,

    Source Code

    1. analyze_command_c_options="-x;c;-std=c11"
    2. analyze_command_cpp_options="-x;c++;-std=c++17;-D__SES_ARM;-D__GNU__;-frtti"
