我无法为Android编译C++(Qt)项目。这个项目是在Linux下编译的,但是当我在arm 64-v8 a下编译我的库,然后编译这个项目时,qt给出了一个错误:
error: undefined symbol: __sendto_chk
referenced by socket.h:72 (/home/misha/Android/Sdk/ndk/25.1.8937393/toolchains/llvm/prebuilt/linux-x86_64/sysroot/usr/include/bits/fortify/socket.h:72)
connect.cpp.o:(OBD::OBDConnectNetwork::sendAllData()) in archive /usr/local/lib/libobd_scanner.a
clang++: error: linker command failed with exit code 1 (use -v to see invocation)
ninja: build stopped: subcommand failed.
我在库中使用系统调用。
当我包含库头时,项目将正确构建,但当我创建对象时,项目将无法构建
以下是CMakeLists:

endif()
当我调用find_package()时,它说没有找到库,但是在Linux程序集下没有这样的问题
我创建了一个没有系统调用的测试库,然后一切正常
如有任何答复,我将不胜感激

我终于解决了我的问题。问题是我在NDK版本25.1.8937393上编译我的库。当我在NDK版本23.1.7779620上编译库时,一切正常
