Bug ID: 69772
Summary: enum class bool comparison error
Product: gcc
Version: 5.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: claytrychta at gmail dot com
Target Milestone: ---
The below code comparing a type of enum class bool fails to compile with this
error:
main.cpp: In function 'int main()':
main.cpp:10:47: error: could not convert 'test' from 'Test' to 'bool'
const char *p = Test::Foo == test ? "a" : "b";
enum class Test : bool
{
Foo,
Bar
};
int main()
{
Test test = Test::Foo;
const char *p = Test::Foo == test ? "a" : "b";
(void)p;
}
Changing the underlying type of the enum to other types (short, int, or long)
works. Also, returning other types in the ternary (such as int) works.
