Bananas compile time with termux

[0dminnimda]

Describe the bug

I've cloned the repo and ran make. After that followd the tutorial. The compile times were quite disappointingly long.

module main

import vweb
import time

struct App {
	vweb.Context
}

fn main() {
	app := App{}
	vweb.run(app, 8081)
}

fn (mut app App) time() vweb.Result {
	return app.text(time.now().format())
}

@['/index']
pub fn (mut app App) index() vweb.Result {
    message := 'Hello, world from Vweb!'
	return $vweb.html()
}

->

$ time v src/main.v

real    0m5.025s
user    0m4.244s
sys     0m0.834s

After that I investigated. And even the hello world takes some time to compile.

fn main() {
    println('hello world')
}

->

$ time v src/hello.v

real    0m1.608s
user    0m1.271s
sys     0m0.336s

And cold cache is not the problem, those are the following compilations

$ time v src/hello.v

real    0m1.574s
user    0m1.257s
sys     0m0.336s
$ time v src/hello.v -stats
        V  source  code size:      16937 lines,     449893 bytes,   145 types,     5 modules,    62 files
generated  target  code size:      13470 lines,     445970 bytes
compilation took: 1532.703 ms, compilation speed: 11050 vlines/s

real    0m1.569s
user    0m1.237s
sys     0m0.353s

Using tcc from pkg install tcc does not seem to help much:

$ time v src/hello.v -cc tcc

real    0m1.569s
user    0m1.244s
sys     0m0.358s

Though when I symlink tcc executable into v/thirdparty/tcc/tcc.exe compile times are much better

time v src/hello.v

real    0m0.215s
user    0m0.197s
sys     0m0.054s

But unfortunaly it seems to break when gc is needed:

$ time v src/main.v

real    0m0.861s
user    0m0.558s
sys     0m0.352s
$ ./src/main
CANNOT LINK EXECUTABLE "/data/data/com.termux/files/home/.../src/main": library "libgc.so" not found: needed by main executable

After I export LD_LIBRARY_PATH=/data/data/com.termux/files/usr/lib:$LD_LIBRARY_PATH another error shows up:

$ ./src/main
CANNOT LINK EXECUTABLE "./src/main": cannot locate symbol "__builtin_nanf" referenced by "/data/data/com.termux/files/home/.../src/main"...

Now I don't think I can do much here.

Reproduction Steps

shown above

Expected Behavior
