Could it run on iOS or android ?

[NeoChow]

Since both of them support the clang compiler.

Hello @NeoChow ,
Good question. I did not try to build oatpp for android, and/or iOS.

If you have possibility to try it would be perfect. I'll provide an assistance in case of any questions.
If you have no possibility, I'll try to do it some time later

@lganzzzo I'll give you a feedback as soon as I've tested it. : )

@lganzzzo Hello Leonid! I am trying out oatpp and oatpp-websocket on Android (and soon iOS) because I need to use Websockets on mobile devices. I have almost gotten it to compile. I have one compiler error that I have not figured out yet. The following error is on line 47 in Thread::setThreadAffinityToCpuRange:

"use of undeclared identifier 'pthread_setaffinity_np'; did you mean 'sched_setaffinity'"

I am using the commits at tag 0.19.1 for both oatpp and oatpp-websocket.

If I change pthread_setaffinity_np to sched_setaffinity in my local copy of Thread.cpp it compiles (and links) successfully.

Do you know why my compiler cannot find pthread_setaffinity_np? Would it be an acceptable workaround to use sched_setaffinity instead?

@NeoChow were you able to build oatpp for Android or iOS?

Hello @dmcamens-legrand ,
Thank you for your interest!

"use of undeclared identifier 'pthread_setaffinity_np'; did you mean 'sched_setaffinity'"
Do you know why my compiler cannot find pthread_setaffinity_np? Would it be an acceptable workaround to use sched_setaffinity instead?

As I understand from https://stackoverflow.com/questions/30801752/android-ndk-and-pthread
pthread is limited on Android. So I guess pthread_setaffinity_np is not available on Android.

As workaround you may just comment it out. Or try to replace it for Android with #ifdefs

I am using the commits at tag 0.19.1 for both oatpp and oatpp-websocket.

Please use 0.19.4 for both. It is much more stable and has a lot of memory-leaks, and crushes fixed.

P.S. Please let me know in case of any questions.

Best Regards,
Leonid

@dmcamens-legrand
please let me know if you have any problems updating from 0.19.1 to 0.19.4

[dmcamens-legrand]

@lganzzzo Thanks for your fast response and the hints! I wanted to use 0.19.4 but I could not find a 0.19.4 tag in the oatpp-websocket repo which is why I used 0.19.1 for both. Which oatpp-websocket commit ID should I use?

[lganzzzo]

@dmcamens-legrand
Created a tag for you https://github.com/oatpp/oatpp-websocket/releases/tag/0.19.4

[dmcamens-legrand]

@lganzzzo Thank you! I will update to 0.19.4 for both. Do you want me to create a PR with the Android workaround?

[lganzzzo]

@dmcamens-legrand Yes sure, it will be cool!

[dmcamens-legrand]

@lganzzzo Ok I will do that, thanks. One more question. Do you have any example code or documentation that describes how to use the WebSocket classes? I checked on the website and I didn't see any examples for WebSockets.

Update: I found the test directory alongside the source code. I will start there!

[dmcamens-legrand]

Or maybe you just have some quick hints like which class to use?

@lganzzzo I tried to push my branch but it said I don't have permission. Do you need to add me as a contributor?

@dmcamens-legrand

Do you have any example code or documentation that describes how to use the WebSocket classes?

https://github.com/lganzzzo/oatpp-example-websocket - this is a simple echo WebSocket server example. This is a "simple" multithreaded websocket server.

You may try to use http://www.websocket.org/echo.html to test this server.
Put ws://localhost:8000/websocket-connect in location field

I tried to push my branch but it said I don't have permission. Do you need to add me as a contributor?

Please fork repo, and create a PR as for "Github flow".

Please let me know if you have any questions.

Regards,
Leonid

Also,

Please don't hesitate asking whatever question you have. - It will help me improve documentation.

Also any feedbacks are valuable.

Thanks for your interest in the project,
