problems compiling catch.cpp with GCC compiler

[tdjastrzebski]

An error was thrown compiling catch.hpp with GCC compiler (GNU Arm Embedded Toolchain 10.3-2021.07)

NMEA2000/third-party/catch/catch.hpp:6516:27: error: 'SA_ONSTACK' was not declared in this scope; did you mean 'SS_ONSTACK'?
 6516 |             sa.sa_flags = SA_ONSTACK;
      |                           ^~~~~~~~~~
      |                           SS_ONSTACK

SA_ONSTACK is not found anywhere. Is there any external module/library required?

catch.cpp also causes a bunch of warnings which may indicate catch.hpp content is not compatible with latest GCC compiler. E.g.
parameter passing for argument of type '__gnu_cxx::__normal_iterator<Catch::SectionEndInfo*, std::vectorCatch::SectionEndInfo >' changed in GCC 7.1

Am I correct that catch.cpp may be excluded from a build for STM32?

[denravonska]

Catch is for running unit tests so I'd say yes, you're correct.
