Qt5Concurrent module missing

NightFury · 10 May 2021, 07:12

I am building an application and I get the below error as "Project ERROR: Unknown module(s) in QT: concurrent". [ have tried adding the QT += concurrent in .pro file and did not change anything]. So I am suspecting if the module is missed during the make module step ??

Which Qt version are you using? Have you compiled it yourself?

Hi Sierdzio,

Thanks for the response.
I am using 5.13 and yes I have compiled it with emscripten. In fact I have built other
required modules and my application is working fine with them.

Ah, so it's for web assembly, I missed that. I'm not sure if QtConcurrent is supported there, especially with such an old Qt version. Consider upgrading to Qt 5.15 or 6.2.

Make sure you read these:

Thanks for the response.
Upgrading will be a task! so I am still with 5.13.
Like other modules built with "make module-qtbase module-qtdeclarative .....etc...." do I need to add some module specific for qt concurrent or that should be built with "make module-qtbase"? or as you suggested this is expected to work with upgrading only ?

I don't know, sorry. I only tried WASM a few times, years ago.
