Hi,
I'm having a few issues building on Linux.

Missing include <cmath> was added to include/utils.hpp which fixed the sqrt/cos/sin errors. I've also added the missing template<> syntax to include/config.hpp but now I get a linker error:

Any ideas?

Hi,
It is compiling fine with vc15 but I guess there are differences between these compilers.
Can you tell me which compliler you are using ? It will be easier for me to reproduce and fix :)
ncoder-1 commented
Just good old g++ but it does the same thing with clang++ as well.
johnBuffer commented
I will look into this :)
johnBuffer commented
It should be better now, tested on Ubuntu 20. Let me know if you have any issues.
ncoder-1 commented
Yep that worked perfectly, thanks!
