Compile the lib for Android with Qt support end with error

Open fro0m opened this issue 2 years ago • 5 comments

How to reproduce;

cmake     -B build     -DCMAKE_TOOLCHAIN_FILE=$NDK/build/cmake/android.toolchain.cmake     -DANDROID_ABI=armeabi-v7a     -DANDROID_PLATFORM=android-27     -D SENTRY_BACKEND=none     -D CMAKE_PREFIX_PATH=/home/kotr/dev/tools/Qt/5.15.2/android/lib/cmake/Qt5/     -D SENTRY_INTEGRATION_QT=YES     --config RelWithDebInfo     -S .

it is fine

go for build: cmake --build build --config RelWithDebInfo --parallel

It unds up with error: image

p.s. specifying diffenrent -DANDROID_ABI=armeabi-v7a parameter does not make any effect

Environment; lib version 0.4.15 OS Kubuntu linux 21.10 x64 cmake 18 Qt 5.15.2

Can you try disabling integration tests when building?

As the linker is complaining about libQt5Core not having the right format; which format does it have? Is it a valid elf file? If so, does it have the same elf architecture, etc?

As you are trying to link to a pre-built qt library, it would be good to double-check that it is indeed matching up.

I tried to find out what is wrong with elf with read elf: readelf -h /home/kotr/dev/tools/Qt/5.15.2/android/lib/libQt5Core_armeabi-v7a.so ELF Header: Magic: 7f 45 4c 46 01 01 01 00 00 00 00 00 00 00 00 00 Class: ELF32 Data: 2's complement, little endian Version: 1 (current) OS/ABI: UNIX - System V ABI Version: 0 Type: DYN (Shared object file) Machine: ARM Version: 0x1 Entry point address: 0x0 Start of program headers: 52 (bytes into file) Start of section headers: 5856160 (bytes into file) Flags: 0x5000200, Version5 EABI, soft-float ABI Size of this header: 52 (bytes) Size of program headers: 32 (bytes) Number of program headers: 8 Size of section headers: 40 (bytes) Number of section headers: 41 Section header string table index: 40

I do not know if it is correct or not, but this Qt prebuilt lib was delivered with official installer in the Qt installation. How should I check ?

That looks good so far. How about the build artifacts in the sentry build directory?

C is known to be a pain to cross-compile (on top of CMake itself being a huge pain), and we have limited resources to support the infinite amount of build configurations and setups that people want to use :-(
