RTS header files can't be used with a C++ compiler
If you compile m1.cpp:
#include "Rts.h"
int main(int argc, char** argv) {
}with:
g++ -g m1.cpp -std=c++11 -I includes/ -cyou get:
In file included from includes/Rts.h:29:0,
from m1.cpp:1:
includes/Stg.h:29:3: error: #error __STDC_VERSION__ does not advertise C99 or later
# error __STDC_VERSION__ does not advertise C99 or later
^It's not advertised anywhere that it should work, but it used to work. https://phabricator.haskell.org/D2045 is what introduced this check.
Judging by https://stackoverflow.com/questions/48045243/ghc-gcc-compiler-issue-stdc-version-w-c99-from-stg-h-fails-for-every-packa, it affects GHC 8.2 and later.
