Description
I use QtCore as like the C++ standard library. But it seems that using QtCore only is not very well on Android platform. When I was instantiating the `QCoreApplication`, the program just crahsed.
The steps to produce the bug:
1. build static Qt for Android using this command line:
./configure --prefix="/usr/local/Qt5.11.1-android-static-x86" -release -opensource -static -no-gui -no-icu -xplatform android-clang -disable-rpath -nomake tests -nomake examples -android-ndk /home/goldfish/bin/android-sdk-linux/ndk-bundle -android-sdk /home/goldfish/bin/android-sdk-linux -android-ndk-platform android-14 -android-arch x86
make -j4 && sudo make install
2. The simplest code to reproduce bug.::
// main.cpp #include <QtCore/qcoreapplication.h> int main(int argc, char **argv) { QCoreApplication app(argc, argv); qDebug("ok!"); return 0; }
3. Build the code using cmake with Android toolchain
#CMakeLists.txt
CMAKE_MINIMUM_REQUIRED(VERSION 3.1.0 FATAL_ERROR)
PROJECT(test002)
SET(CMAKE_AUTOMOC ON)
SET(CMAKE_INCLUDE_CURRENT_DIR ON)
FIND_PACKAGE(Qt5Core CONFIG REQUIRED CMAKE_FIND_ROOT_PATH_BOTH)
IF(ANDROID)
LINK_DIRECTORIES(${_qt5Core_install_prefix}/lib/)
SET(OS_EXTRA_LINK qtpcre2 z log)
ENDIF()
ADD_EXECUTABLE(test002 main.cpp)
TARGET_LINK_LIBRARIES(test002 Qt5::Core ${OS_EXTRA_LINK})
The command line to build:
mkdir build cd build cmake -DANDROID_ABI=x86 -DANDROID_NDK=/home/goldfish/bin/android-sdk-linux/ndk-bundle -DCMAKE_TOOLCHAIN_FILE=/home/goldfish/bin/android-sdk-linux/ndk-bundle/build/cmake/android.toolchain.cmake -DANDROID_PLATFORM=android-14 -DCMAKE_PREFIX_PATH=/usr/local/Qt5.11.1-android-static-x86/lib/cmake .. make -j4
4. Upload the executable to the storage of Android phone.
adb push test002 /data/local/tmp
5. Run executable from Android ADB shell.
adb shell cd /data/local/tmp ./test002
6. It crashes. And print:
Segmentation fault
