>Description:
Given the following source:
using namespace std;
struct Foo {
static const int BAR = 1;
static const int BAZ = 2;
};
int main(int argc, char *argv[])
{
int c = argc ? Foo::BAR : Foo::BAZ;
return 0;
}
and invoked like:
/usr/local/gcc322/bin/gcc test.cpp -o test -lstdc++
I obtain:
/var/tmp//ccu6NK1Z.o: In function `main':
/var/tmp//ccu6NK1Z.o(.text+0x17): undefined reference to `Foo::BAR'
/var/tmp//ccu6NK1Z.o(.text+0x21): undefined reference to `Foo::BAZ'
Since BAR and BAZ are static integer constants, they should not be generating linker references. This happens only with the ternary operator; the equivalent if/else code does not produce the problem.
