Android NDK: Why arm-linux-androideabi-gdb.exe disappeared?

I recently migrated from Android NDK r9b to r11b.

I'm deploying test application using QtCreator, this uses the NDK for compilation.

I'm not able to debug anymore, QtCreator complains that it cannot find arm-linux-androideabi-gdb.exe.

And I confirm:

  • r9b has file toolchains\arm-linux-androideabi-4.8\prebuilt\windows-x86_64\bin\arm-linux-androideabi-gdb.exe
  • r11b does not have it in toolchains\arm-linux-androideabi-4.9\prebuilt\windows-x86_64\bin
  • I downloaded and checked r10e, this one also contains toolchains\arm-linux-androideabi-4.9\prebuilt\windows-x86_64\bin\arm-linux-androideabi-gdb.exe

Why did they remove GDB from release r11b? How are we supposed to debug now?

Edit: Submitted Qt bug: https://bugreports.qt.io/browse/QTCREATORBUG-15933. gdb can be manually picked up somewhere else in NDK folder. However, I was still unable to debug after gdb.exe was found...

Edit2: Problem fixed by Qt. Upgraded to QtCreator 4.0.3. It piskcs up gdb correctly and I could debug my application!

In NDK 11 gdb was moved to $NDK_DIR/prebuilt/$HOST/bin/gdb.

QtCreator was updated for NDK 11. E.g. you can try QtCreator 4.0 beta

Same issue with android-ndk-r10e-windows-x86_64.exe This package has an bug which skips copying arm-linux-androideabi-gdb.exe to the destination folder. Here is my workaround ... Since downloaded android-ndk-r10e-windows-x86_64.exe contains missing arm-linux-androideabi-gdb.exe ...

  • Open 7-zip and extract android-ndk-r10e-windows-x86_64.exe to local folder
  • Open extracted folder and
  • Browse to android-ndk-r10e\toolchains\arm-linux-androideabi-4.9\prebuilt\windows-x86_64\
  • Copy arm-linux-androideabi-gdb.exe to your NDK location

Hope this helps. View listof files in 7-zip
