Im only trying my tutorial to try catch2 unit testing lib. Im using mac with 10.14. I dont have full XCode, only cmd tools and macports runs perfect in my setup (no brew). Im using the amalgamated single header and source file as suggested.
Yet, a simple tutorial:
#define CATCH_CONFIG_MAIN // This tells Catch to provide a main() - only do this in one cpp file
#include "catch.hpp"
unsigned int Factorial( unsigned int number ) {
return number <= 1 ? number : Factorial(number-1)*number;
}
TEST_CASE( "Factorials are computed", "[factorial]" ) {
REQUIRE( Factorial(1) == 1 );
REQUIRE( Factorial(2) == 2 );
REQUIRE( Factorial(3) == 6 );
REQUIRE( Factorial(10) == 3628800 );
}
gives many compile errors - snip:

;
Please suggest, Thanks.
Edit:
After @Tiib suggested to try with g++ -std=c++17 the code got compiled and build. g++ -std=c++11 also did not work. Not understood why.
