Can someone help me out, i am trying to cross-compile to
rpi4 alpine-musl ( 5.4.43-0-rpi4 #1-Alpine SMP PREEMPT Thu May 28 10:01:20 UTC 2020 aarch64 Linux )
form normal pc ( 5.8.8_1 #1 SMP Wed Sep 9 19:53:06 UTC 2020 x86_64 GNU/Linux - voidlinux :) )
So simple code i am using just for testing:
import ws, asyncdispatch, asynchttpserver
var server = newAsyncHttpServer()
proc cb(req: Request) {.async.} =
try:
if req.url.path == "/ws":
var ws = await newWebSocket(req)
await ws.send("Welcome to simple echo server")
while ws.readyState == Open:
let packet = await ws.receiveStrPacket()
await ws.send(packet)
elif req.url.path == "/":
await req.respond(Http200, "Heloo")
else:
await req.respond(Http404, "5min ban for bots!")
except:
return
waitFor server.serve(Port(9010), cb)
What i think(duno for sure anymore) i tryed but did not work:
nim c --cpu:arm64 --passL:"-static -no-pie" src/server.nim

./serv was just that build of /src/server.nim , atm dumped that am just building file.nim that hase just 1 line echo "HelloW"
From what i get i get those errors ")" cuz wrong arch or wrong libc ?
those errors are because the os can't recognize the binary and is trying to execute it as a shell script. I think it's likely because you compiled for 64bit and the default os(raspbian) for rpi4 is 32bits
But why is the OS trying to run the binary at all? The nim commands shown didn't include -r. And the output of server.nim wouldn't be named serv.
Also, why would the OS try to run a binary as a shellscript? It shouldn't do that unless it starts with something like #! /bin/bash...
he's compiled on his laptop, then i'm assuming scp'd them across to the rpi to ~/.serv then run that file over ssh. ...lots of assumptions on my part i admit
the error messages certainly look like something is parsing ./serv and the fact it sometimes finds "ELF" on line 1 indicates it's probably a binary. i googled it and it's not unheard of
@kodkuce If you're running Raspberry Pi OS, it's still a 32 bit OS, even if the raspberry pi itself is 64 bit. You need to compile your code in 32-bit mode.
"if the executable runs on your local machine, if so it hasn't cross compiled properly."
ye i just runed nim --cpu:arm64 --gcc.exe:musl-gcc --gcc.linkerexe:musl-gcc c echotest.nim file echotest.nim has just echo "Test1" and it runned on my x86_64amdPC like it ignored this --cpu:arm64, duno why ?
im --cpu:arm64 --gcc.exe:musl-gcc --gcc.linkerexe:musl-gcc c echotest.nim

Yes, Nim can't find your cross-gcc. Have you got the right``arm.linux.gcc.path`` and the rest in your nim.cfg?
After that, I had to passL the path to the libc as well
From what i see default one hes no defintion for arm64 only for arm i just added myself some new lines just am now trying to figure out what linker name in void-linux packages
>does not work on both rpi and desktop Progress!
ye i put -ld but now i get new errors nim.cfg

SOLVED( thanks to shashlick ): in nim.cfg both exe and linkerexe should point to to same arm64.linux.gcc.exe = "aarch64-linux-musl-gcc" arm64.linux.gcc.linkerexe = "aarch64-linux-musl-gcc"
Sweet! Now you can change the emoticon on your post title ;)
This thread safed my life (meaning, I will be able to use Nim for a client project, instead of Python :) Thanks!
Nice!!!
I'm doing it a little differently because I think using the musl C library means you need to compile statically, but I needed to depend on a dynamic library. So I installed a fairly old GCC (via the arch linux aur repository, other linux distros have other options). This means I have a binary that I can compile dynamically but will be compatible with most boxes.
arm64.linux.gcc.exe = "aarch64-none-linux-gnu-gcc-9.2.1" arm64.linux.gcc.linkerexe = "aarch64-none-linux-gnu-gcc-9.2.1"
