I was trying to compile this amazing work, but on Unix there is slight difference in sleep function.
Sleep is a Windows function
For Unix, nanosleep or usleep
https://stackoverflow.com/questions/10976176/c-error-sleep-was-not-declared-in-this-scope
This is the line, where I ran into problem with compiling on Mint and g++ 9.3.0.
Line 207 in b6a9dbd
So, I replaced Sleep with usleep and uncomment #include <unistd.h> line and it solved my problem.
I'm not a cpp guy, but I think this issue is on point. What do you think?
I tried running the code but the compiler logged errors showing that a lot was not defined. I noticed you didn't call "functions.cpp" in main... I tried but it still didn't work. please fix, I wanna see ray tracing on my potato pc
Hi,
I wanted to check out the demo video, but youtube says it is private. That's probably not intended because the link is in the readme. Could you make it public, please?
If I try to run this program, I always get collect2.exe: error: ld returned 1 exit status error. Here is my terminal output -
g++ .\main.cpp -o ray.exe

What could be the problem? I've tried compiling in ubuntu too and got the same error.
Hi there!
It's looks so nice <3
Just add <unistd.h> to if else statement, and maybe some readme's for linux too ?
#ifdef _WIN32
#include <windows.h>
#else
#include <unistd.h>
#endif 
Also, here's how the project -in case I've done something wrong- looks like:
I've added 3d movements but it's using ncurses
Your "function.h" is impossible to include more than in one place, it will cause "multiple definition" error (I know you include it once, but what if someone else wants to reuse it). This happens because it contains declaration and implementation of functions. If you move implementations to pair functions.cpp file, you would solve this problem.
