Error while trying to build android app. #error Bionic header ctype.h...

So you are including some standard header there in line 8 of main.cpp?

If yes, check if the error also happens in a minimal project without Qt. If so you might want to ask on an Android forum instead,

Cheers,

I've tried that. If I remove any link to C++ or anything outside QML it (the UI) compiles and runs well. Also if I try to run it as a desktop app it works. From digging around the internet I found something suggesting that the compiler is including a header from the system when it should be using one from the android ndk.

Had no luck on finding a solution yet though.

Thanks.

Are you able to build, deploy, and run a simple "Hello world!" program that uses iostream for Android using your build environment?

Your pro file does indeed include a bunch of folders for your native environment: all includes and libraries should be coming from the NDK. It also contains what looks like the wrong name for the freesteam library. Try this cut down version

TEMPLATE = app
QT += qml quick
SOURCES += main.cpp \
    mysteamclass.cpp
RESOURCES += qml.qrc
# Additional import path used to resolve QML modules in Qt Creator's code model
QML_IMPORT_PATH =
# Default rules for deployment.
include(deployment.pri)
HEADERS += \
    mysteamclass.h
#--------------------------------ME= C++11 AND LIBRARIES-----------------#
 
CONFIG+=c++11
LIBS += -lgsl
LIBS += -lfreesteam
LIBS += -lgslcblas

TEMPLATE = app
QT += qml quick
SOURCES += main.cpp \
    mysteamclass.cpp
RESOURCES += qml.qrc
# Additional import path used to resolve QML modules in Qt Creator's code model
QML_IMPORT_PATH =
# Default rules for deployment.
include(deployment.pri)
HEADERS += \
    mysteamclass.h

CONFIG+=c++11
LIBS += -lgsl
LIBS += -lfreesteam
LIBS += -lgslcblas

I am assuming the the three libs have been built with the cross-compiler and installed in the NDK default library path.

Well, I can build and run simple programs but I have to admit that I don't know what exactly an iostream for android is.

I am assuming the the three libs have been built with the cross-compiler and installed in the NDK default library path.

When I installed them I just used the ./run like command from the terminal so I'm assuming the weren't built with a cross compiler! And for sure they're not in the default library path of the NDK.

Going after what you said, it pretty much looks like I'm hopeless huh?

Thank you very much.

If you do not have the freesteam/gsl library built for the Android target you will not get to the finish line. The linker will need these to build a working Android app even if we got past the prsent compilation-stage errors.

It looks like you need quite a few pieces to achieve that.

That's what I figured.

It seems like I heavily underestimated the complexity that hides behind the code once deploy everywhere phrase. I couldn't even manage to deploy and create a (desktop)package for this app, let alone make it work on android.

This may be because I'm fairly new to linux but still. In visual studio it was way easier creating executable files and distributing them. Not cross platform but still very easy to do.

Seems like this has to wait until I find some time to dig deeper in qt and the whole things like writing .pro and make files, cmake, qmake, library cross compilations and all that stuff.

Maybe we'll chat again sometime in the upcoming future, when I get stuck, again.

Thank you for your time.
