I have the following typedef for uint32:
typedef unsigned long long uint32;
Also I have the generic templated class for Hashmap with the following declaration:
template<typename K, typename V>
class Hashmap {
...
public:
explicit Hashmap(uint32 size, float loadFactor = 0.75f) {}
...
}
I use the Hashmap class in another class with actual template parameters uint32 and uint32.
class Interpreter {
private:
uint8 memory[MEMORY_SIZE] = {0};
uint32 pointer = 0;
uint32 programCounter = 0;
std::string program;
std::string outputBuffer;
Hashmap<uint32, uint32>* jumpTable = new Hashmap<uint32, uint32>(256);
...
This however for some reason does not compile and gives a lot of unrelated (in my opinion) and different errors across all the files. (The complete list of them is at the end of the question)
But if I replace the uint32 in the Hashmap constructor invocation with unsigned long long the code magically compiles and all the errors disappear. What is even more strange is that the same code compiles on some compilers but not on this one.
Hashmap<uint32, uint32>* jumpTable = new Hashmap<unsigned long long, unsigned long long>(256);
What is the reason for this behaviour? Why is this happening? And how can I write the class to be compilable on different compilers?
I am using CMake which is using c++:
$ c++ -v
Using built-in specs.
