Comiler errors after upgrade in VS Code/PlatformIO

[chessweb01]

After updating PlatformIO in Visual Studio Code 1.17.2 I get the following errors when compiling my project:

[chessweb01]

This seems to be related to issues #56, #57, #58. The problem are the following function calls in ESPAsyncTCP.cpp:

tcp_recv(_pcb, &_s_recv);
tcp_sent(_pcb, &_s_sent);
tcp_err(_pcb, &_s_error);
tcp_poll(_pcb, &_s_poll, 1);
tcp_accept(_pcb, &_s_accept);

Adding explicit type conversions

tcp_recv(_pcb, (tcp_recv_fn)&_s_recv);
tcp_sent(_pcb, (tcp_sent_fn)&_s_sent);
tcp_err(_pcb, (tcp_err_fn)&_s_error);
tcp_poll(_pcb, (tcp_poll_fn)&_s_poll, 1);
tcp_accept(_pcb, (tcp_accept_fn)&_s_accept);

fixes my issue.

This has been fixed in master and can be closed?

[chessweb01]

No, as far as I can see it is not fixed in master as the type conversions are not implemented. The only other way to fix the problem is to change the function prototypes in lwip/tcp.h which is a file belonging to the arduinoespressif8266 framework.

[atanisoft]

this is due to the platformio espressif8266 version still being 1.4.0 and not the 2.4.0 that has the new prototypes. You can fix this by specifying this in your platformio.ini:

[env:esp8266]
platform=https://github.com/platformio/platform-espressif8266.git#feature/stage
[email protected]

at least this is what worked for me.

[chessweb01]

You are right, works for me, too.

[andig]

Sorry, forgot to say that I‘m using feature/stage.

[watershade]

I have meet the same problem. And thank for all yours'work.

[me-no-dev]

closing :)
