Trying to build QMsgPack lib for Android 6.2.0 Clang arm64-v8a

@SGaist hmm so my app just keeps crashing with

You need to deploy it as well. See here for more information about that matter.

@SGaist my .pro has

win32:CONFIG(release, debug|release): LIBS += -LC:/build-qmsgpack-Android_Qt_6_2_0_Clang_arm64_v8a-Release/android-build/libs/arm64-v8a/release/ -lqmsgpack_arm64-v8a
else:win32:CONFIG(debug, debug|release): LIBS += -LC:/build-qmsgpack-Android_Qt_6_2_0_Clang_arm64_v8a-Release/android-build/libs/arm64-v8a/debug/ -lqmsgpack_arm64-v8a
else:unix: LIBS += -LC:/build-qmsgpack-Android_Qt_6_2_0_Clang_arm64_v8a-Release/android-build/libs/arm64-v8a/ -lqmsgpack_arm64-v8a

INCLUDEPATH += C:/build-qmsgpack-Android_Qt_6_2_0_Clang_arm64_v8a-Release/android-build/libs/arm64-v8a
DEPENDPATH += C:/build-qmsgpack-Android_Qt_6_2_0_Clang_arm64_v8a-Release/android-build/libs/arm64-v8a

that should be enough? :S

SGaist

Did you read the documentation I linked to ?

There's a difference between building and deploying.

Kris Revi

@SGaist so im not deploying when i press "Run" i Qt Creator? :S

SGaist

In certain way, yes. But you are using an external library, so you have to tell the system that you want to deploy it as well. That is what is explained in the documentation I linked above.

@SGaist ok i got it working! i guess? i mean the app is running on my tablet fine but how do i enable debugging? :S

Kris Revi

all i get is this

W ActivityThread: Application org.qtproject.example is waiting for the debugger on port 8100...
I System.out: Sending WAIT chunk

SGaist

Did you enable debugging on your device ?

Kris Revi

@SGaist yea i have! it was just SUPER slow :S it is working now :) thank you a million for this!!! i have taken notes of this! so that i know this in the future :)
