I saw a lot of similar questions, but I don't think I saw quite the same one. It's pretty basic. Some code from my lecturer is failing to compile, and I distilled the problem to this test case:
void foo(vector<int> v) {
}
void fooUsage() {
foo({0, 1, 2});
}
This fails with:
could not convert '{0, 1, 2}' from '<brace-enclosed initializer list>' to 'std::vector<int>
Note: It works on GCC 5.0.0 20141228 but fails on my GCC 4.7.1 (tdm-1).
Sorry if this is too basic but I don't know C++11 very well.
This is a known bug that was fixed in gcc 4.8.
It turns out I only needed to add -std=c++11
to the gcc command line.
Note: I was mistakenly thinking that this is on by default, since I was also getting some warnings like this:
extended initializer lists only available with -std=c++11 or -std=gnu++11 [enabled by default]
See how it says "enabled by default"? That's what was misleading me.
