Configure wants -android-ndk-host, even when I already provided it

[RudolfVonKrugstein]

Hey,

I am trying to build Qt for android following the instructions here: http://qt-project.org/wiki/Qt5ForAndroidBuilding

This is what I do for configure:

@
./configure -developer-build -platform linux-g++-64 -xplatform android-g++ -nomake tests -nomake examples -android-ndk /home/ls/src/android-ndk -android-sdk /home/ls/src/android-sdk -skip qttools -skip qttranslations -skip qtwebkit -skip qtserialport -android-ndk-host linux-x86_64
@

The error I get is:

@
Can not detect the android host. Please use -android-ndk-host option to specify one
@

I am confused, I povided that option. Why is it ignoring it?

Thanks!

You have a typo there. Its -android-ndk-host, not android-ndk

[RudolfVonKrugstein]

No, the last option is
@-android-ndk-host linux-x86_64@

[Moster]

Oh yeah sry, my bad. Can I know what system you are on?
Also, make sure you really use the correct ndk. There is a x86 and x64 variant.

[RudolfVonKrugstein]

Well, that was the problem. I had the x86 version installed, but I am on a 64bit system. So i downloaded the newest x86_64 version, and it worked.

I hade to add the option: @-android-toolchain-version 4.8@ becuase version 4.7 is not present anymore.

[Moster]

You can still use 4.7, but you need to download the ndk legacy zip.

Mmh, ok. Is there any reason why I should?

Thanks by the way!

Actually no. Since google seems to trust it, you can do that, too.
I only disliked the warnings that it gave me due to the new c++11 standard :D
