Issue
I've compile the android source source ./build/envsetup.sh lunch aosp_x86_64-eng
when I run emulator64-x86 in terminal, error occur:
emulator64-x86: /usr/lib/x86_64-linux-gnu/libQt5Core.so.5: version `Qt_5.7' not found (required by emulator64-x86)
emulator64-x86: /usr/lib/x86_64-linux-gnu/libQt5Core.so.5: version `Qt_5' not found (required by emulator64-x86)
emulator64-x86: /usr/lib/x86_64-linux-gnu/libQt5Widgets.so.5: version `Qt_5' not found (required by emulator64-x86)
emulator64-x86: /usr/lib/x86_64-linux-gnu/libQt5Gui.so.5: version `Qt_5' not found (required by emulator64-x86)
I've found qt in
/home/wanyu/work/aosp/prebuilts/android-emulator/linux-x86_64/lib64/qt/
this directory include libQt5Core.so.5.7, libQt5Widgets.so.5.7 etc.
but libQt5Core.so in
/usr/lib/x86_64-linux-gnu/
version is 5.5
I've tried to set LD_LIBRARY_PATH to:
/home/wanyu/work/aosp/prebuilts/android-emulator/linux-x86_64/lib64/
but the error still occur.
Copying the libQt5Core.so.5 to
/usr/lib/x86_64-linux-gnu/
will solve this error, but qt platform plugin libqxcb won't work.
How I can change the lib path to the
/home/wanyu/work/aosp/prebuilts/android-emulator/linux-x86_64/lib64
when I run emulator64-x86?
Solution
Leave libQt5Core.so.5 in /home/wanyu/work/aosp/prebuilts/android-emulator/linux-x86_64/lib64/qt/. Qt does not like to be moved around, it makes it lose where the plugins are stored. In your case it might end up trying to load Qt 5.5 plugins.
Set LD_LIBRARY_PATH to /home/wanyu/work/aosp/prebuilts/android-emulator/linux-x86_64/lib64/qt/.
Use ldd to check which library will be used when running.
Also note that qxcb requires X11 to run.
