Is there a way I can read files at compile time? AFAIK it's not possible to do using stl, but maybe there is a slightly esoteric way of doing this? Thanks

You cannot read a file at compile time

#

C23 got #embed, C++26 will probably get it

#

You can hack your own #embed with python in many cases

If you make the file you want to read into parseable cpp code (ie a const global array or something) you can #include it 😉

theres also INCBIN, to include binary files.

That's cool, it'll get the binary data in at link time. Unfortunately won't get the binary data in at compile time if that's a strict requirement.

Good to know, thanks! I'll leave this question opened for a bit longer in case something pops up
