Call to 'abs' is ambiguous. Hash.h

[Nestor18]

I have downloaded your Glitter program to run openGL on my macOS 10.13.6 using Xcode version 10.1 but I get the above error message in this line of code:

hash ^= abs(data[sizeof(uint16_t)]) << 18;

I would appreciate any suggestions for a fix.

Regards.

Hi! Can you provide a more detailed stack trace or line number in which this code occurs? I’m pretty sure your issue is with one of the dependencies included. I’d suggest following up with the appropriate project on GitHub.

Thank you, I tried to download a stack trace with no success, but the line number is 99 if that is helpful. It belongs in the assimp 1 library with a call to hash.h. I've copied where it lives in a switch structure. /* Handle end cases */ switch (rem) { case 3: hash += get16bits (data); hash ^= hash << 16; hash ^= abs(data[sizeof(uint16_t)]) << 18; hash += hash >> 11; break; case 2: hash += get16bits (data); hash ^= hash << 11; hash += hash >> 17; break; case 1: hash += *data; hash ^= hash << 10; hash += hash >> 1; } I will try to follow the project as suggested. Regards

/* Handle end cases */
switch (rem) {
case 3: hash += get16bits (data);
hash ^= hash << 16;
hash ^= abs(data[sizeof(uint16_t)]) << 18;
hash += hash >> 11;
break;
case 2: hash += get16bits (data);
hash ^= hash << 11;
hash += hash >> 17;
break;
case 1: hash += *data;
hash ^= hash << 10;
hash += hash >> 1;
}

I think you’ll want to take this up with the assimp maintainers then.

Thanks, will do
