That's my environment variables:

Code:

---

SETX QMAKESPEC "win32-g++"
SETX QTDIR "c:\qt"
SETX include "c:\qt\qtbase\include;c:\icu\include"
SETX lib "c:\qt\qtbase\lib;c:\icu\lib"
SETX PATH "c:\perl\perl\bin;c:\perl\perl\site\bin;c:\mingw\bin;c:\qt\qtbase\bin;c:\qt\qtrepotools\bin;c:\qt\gnuwin32\bin;c:\python\installdir;c:\icu\bin"
 
SETX ANDROID_NDK_PLATFORM "android-9"
SETX ANDROID_TARGET_ARCH "armeabi-v7a"
SETX ANDROID_BUILD_TOOLS_REVISION "19.0.2"
SETx ANDROID_NDK_HOST "windows"

---

That's my configure command, beore i start the compiling process:

Code:

---

configure -platform win32-g++ -debug-and-release -opengl desktop -xplatform android-g++ -android-ndk c:\android-ndk -android-sdk c:\android-sdk -android-toolchain-version 4.7 -opensource

---

Thanks in advance

You have to do something like this to configure qt for android:-

Code:

---

./configure -xplatform android-g++ -nomake tests -nomake examples -android-ndk <path/to/ndk> -android-sdk <path/to/sdk> -android-ndk-host <e.g. linux-x86_64> -android-toolchain-version <e.g. 4.8> -skip qttranslations -skip qtwebkit -skip qtserialport -skip qtwebkit-examples -no-warnings-are-errors

---

You need a JDK (version 1.6) and you should have this in your PATH. The $JAVA_HOME environment variable needs to be pointing to its directory (e.g. /usr/lib/jvm/java-6-openjdk-i386). Also you’ll need to have defined $ANDROID_SDK_ROOT pointing to the SDK and $ANDROID_API_VERSION pointing to the used android.jar API version (e.g. android-19)

Hi,

thank you for the answer.

The option "-android-ndk-host" is not available (Qt 5.2.1). So my new configure command is:

Code:

---

c:\android> c:\qt\configure -developer-build -platform win32-g++ -opengl de
sktop -xplatform android-g++ -android-ndk c:\android-ndk -android-sdk c:\android
-sdk -android-toolchain-version 4.7 -opensource -confirm-license -nomake tests -
nomake examples -skip qttranslations -skip qtwebkit -skip qtserialport -skip qtw
ebkit-examples

---

I have add to my environment variables

Code:

---

JAVA_HOME "C:\Program Files\Java\jdk1.7.0_51"

---

Now i get an new error, but im not sure why Qt is missing "moc_qabstractanimation.cpp", can you help me?

Code:
