Hey Zeno,
long delay :) Do you still have access to that sysroot, or an equivalent one?
I assume that you are talking about these checks:
check_library_exists(${LIBUNWIND_LIBRARY} unw_getcontext "" LIBUNWIND_HAS_UNW_GETCONTEXT)
check_library_exists(${LIBUNWIND_LIBRARY} unw_init_local "" LIBUNWIND_HAS_UNW_INIT_LOCAL)
check_library_exists(${LIBUNWIND_LIBRARY} unw_backtrace "" LIBUNWIND_HAS_UNW_BACKTRACE)
check_library_exists (${LIBUNWIND_LIBRARY} unw_backtrace_skip "" LIBUNWIND_HAS_UNW_BACKTRACE_SKIP)
What do you get for `nm -a path/to/libunwind.so | grep unw_`? Most notably, only unw_backtrace should be required (and available).
Sorry, don't have it anymore. I just tried cross-compiling it with a buildroot toolchain for basically the same hardware with same settings and it works there.. well minus the ECM thing reported here: https://bugs.kde.org/show_bug.cgi?id=392320 I'll mark this as invalid, it was probably some bug in my old setup. |
Created attachment 104430 [details] CMake cross compile file I have a yocto cross compile setup, when trying to compile heaptrack it apparently doesn't find the symbols in the libunwind.so. Not entirely sure this bug is valid as there might be something unusual with my setup. Anyway, some details: Target hardware: i.MX6 Duo Cmake command: cmake /path/to/heaptrack -G'Unix Makefiles' -DCMAKE_BUILD_TYPE:STRING=Release -DCMAKE_TOOLCHAIN_FILE:STRING=toolchain.cmake -DHEAPTRACK_BUILD_GUI:BOOL=OFF -DQT_QMAKE_EXECUTABLE:STRING=/path/to/hosttools/usr/bin/qt5/qmake toolchain.cmake attached When commenting out the checks it compiles at least (though it seems to crash on the device - need to debug this further, might be unrelated)
