Unable to configure Android on Windows 7 x64 using GCC 4.9



  • Hey,

    I currently have the following setup:

    Windows 7 x64
    JDK 1.7.0_79
    Android SDK r24.1.2
    Android NDK r10c
    Qt 5.4.1 and Qt Creator 3.4

    But am unable to get the proper GDB path for python support. Qt Creator complains that "The GDB in the NDK appears to have broken python support." So I click the link and download the "patched" GDB for Windows x86_64. Then I merge the "build", "prebuilt", and "toolchains" folders into my ndk-r10c installation directory replacing any existing files.

    After all this, Qt Creator still complains that the GDB in the NDK path has broken python support. REstarting Qt Creator and going back to the Android settings page immediately throws the error: "The program can't start because libpython2.7.dll is missing..." for "aarch64-linux-android-gdb-orig". I tried simply copying the dll into the directory with that executable only to get a generic crash after that.

    I believe the problem is that there are no patched toolchains for "arm-linux-androideabi-4.9". Is Qt for Android using GCC 4.9 entirely broken, or are there prebuilt binaries I should be downloading for 4.9? Note that the rest of my setup is fine because I can successfully deploy and debug a plain-old Java app in Android Studio to a real device.



  • Note that I am able to configure and deploy using ndk-r9d with GCC 4.8, but debugging does not work at all on a Galaxy S6. Setting a breakpoint in main(), nothing is hit. Note that I am able to debug using Android Studio for a regular Java app on the device. This is the application output:
