array.h headers 错误

Question

我使用 CLion，我有这个简单的代码：

#include <array>

int main() {

    std::array<std::uint64_t, 3> arr;
    return 0;
}

在我的 CMakeLists.txt 中，我尝试了从 c++11/gnu++11 到 c++17/gnu++17 的所有编译器标志，但是在尝试构建以上代码

这是我的 g++ 版本：gcc 版本 8.1.1 20180502 (Red Hat 8.1.1-1) (GCC)。什么会导致此错误？

Answer 1

如果包含路径（/pathToCLionProject/my_project、/pathToCLionProject/my_project/dev/hmmenc_client、/usr/local/include/pqxx、/usr/pgsql-10/include).
