Bug ID: 98030
Summary: error message for enum definition without ';' could be
improved
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: tangyixuan at mail dot dlut.edu.cn
Target Milestone: ---
Hi, the following code misses a ';' at the end of the enum definition. 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.
