Hello, i am new in Nim.
I am testing this example and want compile with useNimRtl for use dynlib in the future.
The example code is
import asyncnet, asyncdispatch, net, osproc, os
var server: AsyncSocket
let port = 9090
let publicKey = "publicKey.pem"
let secretKey = "secretKey.pem"
proc handle(client: AsyncSocket) {.async.} =
while true:
var line: string = ""
try:
line = await client.recvLine()
except:
echo "socket breaks in read:", getCurrentExceptionMsg()
break
if line == "":
echo "client disconnected"
if not client.isClosed:
client.close()
break
try:
await client.send("GOT: " & line & "\n")
except:
echo "socket breaks in send:", getCurrentExceptionMsg()
break
proc createKeyFiles() =
## creates neccessary certificates for ssl socket.
echo "[+] going to create ssl certificates"
let res = execCmd "openssl req -x509 -nodes -days 365 -newkey rsa:1024 -keyout " & secretKey & " -out " & publicKey
if res != 0:
echo "[-] could not create keyfiles"
quit()
echo "[+] keys created"
proc main() {.async.} =
if not (fileExists(publicKey) or fileExists(secretKey)): createKeyFiles()
server = newAsyncSocket()
server.setSockOpt(OptReuseAddr, true)
server.setSockOpt(OptReusePort, true)
server.bindAddr(Port port)
server.listen()
var ctx = newContext(certFile = publicKey, keyFile = secretKey)
wrapSocket(ctx, server)
echo "listening on port ", port
while true:
var (address, client) = await server.acceptAddr()
echo "connection from: ", address
wrapConnectedSocket(ctx, client, handshakeAsServer)
asyncCheck client.handle
waitFor main()

My dev environment is linux mint 19.1 amd64. I test compile with stable Nim 0.20.0 and devel.

When execute the application get:

If compile without -d:useNimRtl work well.
