GCC reports an error with 'new types may not be defined', which may not be easily understood by novices, while clang suggests the additional ';' could be better. $ cat s.cpp enum E { e = 3, } //miss a ';' here int main() { bool var1 = e; bool var2 = 3; } $ g++ -c s.cpp s.cpp:1:1: error: new types may not be defined in a return type 1 | enum E { | ^~~~ s.cpp:1:1: note: (perhaps a semicolon is missing after the definition of ‘E’) s.cpp:1:1: error: two or more data types in declaration of ‘main’ $ clang++ -c s.cpp s.cpp:3:2: error: expected ';' after enum } ^ ; 1 error generated. $ g++ -v Using built-in specs.

A fixit that can be used with all the fixit-related machinery would still be more useful though. ^ permalink raw reply [flat|nested] 4+ messages in thread
