Using pri file

[huseyinkozan]

Hi, I created a console app and tried to include pri file like;

# QMQTT
QT     += websockets
CONFIG += QMQTT_WEBSOCKETS
CONFIG += NO_UNIT_TESTS
DEFINES += QT_WEBSOCKETS_LIB
include($$PWD/../thirdparty/qmqtt-1.0.1/qmqtt.pri)

But I got below errors. How can I use pri file ?

Note; I have added some destructors to suppress warnings/errors

@ejvr any idea? Could it be that moc isn't run on the websocket's code?

[ejvr]

Yep, looks like you're right. It appears that the websocket headers are not passed to qmake.

@huseyinkozan In the file qmqtt.pri in the root of the repo, can you change PRIVATE_HEADERS to HEADERS (line 55). That would force the moc to process the websocker headers.

@ejvr Thanks. It builds now

@ejvr But usually this should be working, so we shall not modify our qmqtt.pri file? I am just asking if we should close the bug or deliver this change.

That's the plan, I hope I can find some time thing week to create a pull request.

Got to recreate my build env first...
