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

Kris Revi

@SGaist aaah i found it :)

SGaist

Did you check the content of the build folder ?

Kris Revi

@SGaist

Build Folder

src folder

release folder

SGaist

There are several folders, what's in them ?
Do you have any library ?
If memory serves well, there should be a bin folder somewhere.

Kris Revi

@SGaist i posted 2 more pictures above btw!

this is the bin folder

no libs :/

SGaist

On the contrary, you have two libraries !

They have their architecture as part of their name, hence the linker does not find them to link to the test.

If your rename them both without the arm64_v8a part, it should work.

Kris Revi

@SGaist now i got a diff error

SGaist

In the absolute, you can ignore that as the libraries were built so you can use them in your main application.

Otherwise, you can add a dummy application in a separate subdirs project to "finalize" things.

Kris Revi

@SGaist

what do i pick when adding a lib to my main project? :S

SGaist

You do the same as in the tests.

So you should get automatic selection of the debug or release build of the library.

Kris Revi

@SGaist hmm so my app just keeps crashing with

SGaist

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

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.

Kris Revi

@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 ?
