Running in OSX giving `Illegal instruction: 4` #8

Closed thesteeltoenail closed 7 years ago

thesteeltoenail commented 7 years ago

Here's my code:

#include <iostream>
#include <cmath>
#include "FastNoiseSIMD.h"
FastNoiseSIMD* noise = FastNoiseSIMD::NewFastNoiseSIMD();

int main() {
}

And my compile script

rm noise
g++ cpp/main.cpp cpp/FastNoiseSIMD.cpp -msse2 cpp/FastNoiseSIMD_sse2.cpp -msse4.1 cpp/FastNoiseSIMD_sse41.cpp -march=core-avx2 cpp/FastNoiseSIMD_avx2.cpp -std=c++11 -o noise
chmod +x noise

I compile with no errors. When I run './noise' it says: Illegal instruction: 4

Auburn commented 7 years ago

You have to compile each instruction set file separately making sure to only set the correct -flag for its matching file. Currently everything it being compiled with avx2 and causing illegal instruction error.

Then do I link them to the main file? Or do I create different files for different processors?

I compiled it with

and I get

It looks like you are compiling FastNoiseSIMD.cpp multiple times and it's causing duplicate symbols.

I'm sorry I bothered you!

You also need to compile FastNoiseSIMD_internal.cpp

That's weird. It works just fine.

thesteeltoenail commented 7 years ago

Also, how is the preview able to render so fast? My code takes about 100ms to render exactly the same thing. (10x slower)

Auburn commented 7 years ago

FastNoiseSIMD Preview only measures the time it takes to generate the noise, not the time taken to turn it into an image.

Can you show me your noise generating code

Are you comparing it to running FastNoiseSIMD preview on the same PC, and are you compiling with high optimisation?

I'm not comparing it to the same pc or compiling with high optimisation. What's the flag for that? Thanks so much!

Auburn commented 7 years ago

It depends on your compiler
