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

Kris Revi

@SGaist yupp! deleted it and the rebuild it

Kris Revi

im still at a loss here :/ any help would be awsome!

SGaist

Put back the tests.

TEMPLATE = subdirs

SUBDIRS += \
    src \
    tests

tests.depends = src

And select a test as build target.

Kris Revi

@SGaist "And select a test as build target." ? :S how do i do that?

SGaist

On the left of Qt Creator, the target selection part.

Kris Revi

@SGaist aaah i found it :)

Kris Revi

@SGaist

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.
