Compile fails with SSL enabled

[AcuarioCat]

Hi,
when I compile with ASYNC_TCP_SSL_ENABLED defined I'm getting a load of errors (without it is fine):
SyncClient.cpp.o*: In function SyncClient::attachCallbacks_Disconnect()
SyncClient.cpp:209: undefined reference to AsyncClient AsyncClient(tcp_pcb*, SSL_CTX*)
SyncClient.cpp:209: undefined reference to AsyncClient connect(IPAddress, unsigned short, bool)

Error linking for board NodeMCU 1.0 (ESP-12E Module)

SyncClient.cpp.o*: In function SyncClient::connect(IPAddress, unsigned short, bool)
Build failed for project 'TestSSL'
SyncClient.cpp:71: undefined reference to AsyncClient AsyncClient(tcp_pcb*, SSL_CTX_*)
SyncClient.cpp:64: undefined reference to AsyncClient connect(IPAddress, unsigned short, bool)

SyncClient.cpp.o*: In function SyncClient::connect(IPAddress, unsigned short)
SyncClient.cpp:76: undefined reference to AsyncClient connect(char const*, unsigned short, bool)

SyncClient.cpp.o*: In function SyncClient::connect(char const*, unsigned short, bool)
SyncClient.cpp:94: undefined reference to AsyncClient AsyncClient(tcp_pcb*, SSL_CTX_*)

SyncClient.cpp.o*: In function _M_init_functor
functional:1987: undefined reference to AsyncClient connect(char const*, unsigned short, bool)

collect2.exe*: error: ld returned 1 exit status

Any ideas? I'm using the latest Arduino build.

Did you ever get this working?

I'm having a similar same issue, both with the SyncClient.h and the ESPAsyncClient.h lib files. I'm on ESP8266 2.4.1 updated from Github. I've modified the SyncClient Example to test SSL connection:

#define ASYNC_TCP_SSL_ENABLED true

#include <SyncClient.h>
#include <ESP8266WiFi.h>

const char* ssid = "***************";
const char password = "*****************";

void setup(){
Serial.begin(115200);
WiFi.begin(ssid, password);
if (WiFi.waitForConnectResult() != WL_CONNECTED) {
Serial.printf("WiFi Failed!\n");
return;
}
Serial.printf("WiFi Connected!\n");
Serial.println(WiFi.localIP());

SyncClient client;
if(!client.connect("www.google.com", 443, true)){
Serial.println("Connect Failed");
return;
}
client.setTimeout(2);
if(client.printf("GET / HTTP/1.1\r\nHost: www.google.com\r\nConnection: close\r\n\r\n") > 0){
while(client.connected() && client.available() == 0){
delay(1);
}
while(client.available()){
Serial.write(client.read());
}
if(client.connected()){
client.stop();
}
} else {
client.stop();
Serial.println("Send Failed");
while(client.connected()) delay(0);
}
}

void loop(){
delay(0);
}

The compiler returns the following errors:

C:\Users\BRENDA~1\AppData\Local\Temp\arduino_build_514642\sketch\sketch_jun13a.ino.cpp.o:(.text.setup+0x2c): undefined reference to `SyncClient::connect(char const*, unsigned short, bool)'

C:\Users\BRENDA~1\AppData\Local\Temp\arduino_build_514642\sketch\sketch_jun13a.ino.cpp.o: In function `setup':

C:\Users\BrendanRoss\Documents\Arduino\sketch_jun13a/sketch_jun13a.ino:9: undefined reference to `SyncClient::connect(char const*, unsigned short, bool)'

I modified the SyncClient example with some ASyncClient code and I get the same undefined reference error for the same connection definition.

Any clues as to why?

Hello this issue is still open ? I get the same issue after defining MACRO ASYNC_TCP_SSL_ENABLED

[minkosimon]

How I could fix this issue ?
