PCH for rAthena - Compilation sucks

[MathReaper]

Have you realized how long the rAthena needs to be compiled? 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.

First compilation takes around 20 seconds only. after that it depends. mine compile around 2-5 seconds with few src edits. but yes, PCH have a very good impact.

Really? Interesting.

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

Yeah. well, just using MSbuild on bat file helps a lot. mine is 7th gen i7 only though..

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).

[Haruka Mayumi]

Yea, it's really a problem when compiling on low budget VM's.. somehow it takes time for me too to compile there. more than 30 seconds or 1 minute?. 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.

On m dedicated server: compile time 10s, using clean previous compilation.

Dedicated are really expensive, isn't it? I think this will improve compile time for low budget servers.

How are you see a precompiled static headers in a dynamically developed project with around ~200k source code lines, which every single day changed several times per day?
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.
