Hi,

Any reason to not merge asynchttpserver diff into Nim stdlib, and have cosmopolitan support from compiler, like have for musl?

Here's the error that I'm getting:

/usr/bin/ld.bfd: errno: TLS reference in /usr/lib64/libm-2.34.a(w_pow.o) mismatches non-TLS reference in /home/ajusa/.cache/nim/main_d/stdlib_io.nim.c.o
/usr/bin/ld.bfd: /usr/lib64/libm-2.34.a: error adding symbols: bad value
collect2: error: ld returned 1 exit status

Looks like something to do with libm. Is it trying to link against my libm rather than the cosmopolitan version maybe?

Hello, I wrote a little code to hexdump files in colors, but the produced executable seems not to be valid:

OSError: [Errno 8] Exec format error: './chex.com'

import terminal
import os
import strutils

proc reset() {.noconv.} =
  stdout.write("\u001b[0m\n")
  quit()

setControlCHook(reset)

let cols = terminalWidth()

var
  f: File
  i:int = 0
  l: array[1024, uint8]
  mono = false
  r: int

if isatty(stdin):
  case paramCount():
  of 0:
    echo "filename expected"
    quit()
  of 1:
    f = open(paramStr(1), fmRead)
  else:
    mono = true
    f = open(paramStr(2), fmRead)
else:
  f = stdin

r = f.readBytes(l,0,cols*2)
while r>0:
  if mono:
    for j in 0..cols*2-1:
      if j >= r: break
      stdout.write("\u001b[38;5;" & $l[j] & "m█")
      i += 1
      if (i mod cols) == 0:
        stdout.write("\n")
  else:
    for j in 0..cols-1:
      if j >= r:
        stdout.write("\u001b[0m" & " ".repeat(cols-j)) # for urxvt bug
        break
      var bg = "\u001b[48;5;" & $l[cols+j] & "m"
      if r <= cols:
        bg = "\u001b[49m"
      stdout.write( bg & "\u001b[38;5;" & $l[j] & "m▀")
      i += 1
      if (i mod cols) == 0:
        stdout.write("\n")

  r = f.readBytes(l,0,cols*2)

reset()

Hello,
I tried using cosmonim to compile a command line project, but I got this error:

/home/ajusa/.cache/nim/main_r/stdlib_terminal.nim.c: In function ‘terminalWidth__s9bdJLFVciGfQ0i2sQaMF1g’:
/home/ajusa/.cache/nim/main_r/stdlib_terminal.nim.c:204:28: error: ‘L_ctermid’ undeclared (first use in this function)
  204 |  cterm = mnewString(((NI) (L_ctermid)));

My guess this is related to an OS level binding for which terminal this code is being compiled for.

https://github.com/nim-lang/Nim/blob/9819fb21d8db818c0b3027d4e6ba58dc550b77c0/lib/pure/terminal.nim#L241 appears to be the terminal code.

My nim version is

Nim Compiler Version 1.4.4 [Linux: amd64]

Let me know if you need any more information!

Looks like as of Cosmopolitan 3.1 (and maybe 3?) https://github.com/jart/cosmopolitan/releases/tag/3.1 cosmocc is included as a C compiler that uses Cosmopolitan for building binaries.

That might be an easier way to build cross platform Nim binaries, similar to the way folks have been using zig cc and tcc - it is easier to swap out the C compiler in Nim.

I think it is as simple as adding the following to a config.nims, but I haven't tried:

  switch("cc", "cosmocc")
  switch("clang.exe", "cosmocc")
  switch("clang.linkerexe", "cosmocc")
