It's really a long time. I'm surprised that a big project like rAthena doesn't have pre-compiled header (PCH) for speed up the compilation time. My question is: Why? Why rAthena don't have PCH yet? Actually, it's needed at least 3 minutes to compile on my PC with MSVS2017 compiler and an avarage of 5 minutes to be compiled in a single core VM with G++ compiler. So, I think we can include PCH to rAthena based on how much includes from STL we have (without counting those that will be included when the project start really looking like C++) and based that rAthena have a core shared for all the servers. Well, that's just my opinion, comment your too. Edited December 5, 2018 by MathReaper Quote Link to comment Share on other sites More sharing options...

Really? Interesting. I have an Intel i7 8700k and it's quite expensive the compilation time here. I took 3 seconds to rebuild however.

True, but I have alot of mods on the src because I'm working on a C++ refactor, so, is more easy to me to just press F7. :v But the point is, the more important are the GCC compilers that takes too much time to compile or clean-compile in low budget VM (at least in all my VM and Clouds take a really long time to complete). 1 Quote Link to comment Share on other sites More sharing options...

So having PCH is really nice. But my opinion somehow is if they made one then that's good. but if not, we just compile on VM every once in a while since we test them on our pc anyway. 1 Quote Link to comment Share on other sites More sharing options...

Dedicated are really expensive, isn't it? I think this will improve compile time for low budget servers. Quote Link to comment Share on other sites More sharing options...

Also, compilation never was an issue on VPS/Dedi servers. Never ever. It takes up to a few minutes maximum (first compilation), and few seconds or less if done just small source edit. If it took a longer time for you - try to change your VPS/Dedi server provider because they for sure oversell their CPU. Quote Link to comment Share on other sites More sharing options...
