cmake 交叉编译 boost link 错误
cmake cross compile boost link error
对于我的程序，我想使用一些增强库，但是当我制作程序时出现错误：
/home/ubunturik/rpinew/rootfs/usr/lib/arm-linux-gnueabihf/libboost_regex.so: undefined reference to `std::__throw_out_of_range_fmt(char const*, ...)@GLIBCXX_3.4.20'
/home/ubunturik/rpinew/rootfs/usr/lib/arm-linux-gnueabihf/libicuuc.so.52: undefined reference to `__cxa_throw_bad_array_new_length@CXXABI_1.3.8'
collect2: error: ld returned 1 exit st
我遵循了本教程 http://amgaera.github.io/blog/2014/04/10/cross-compiling-for-raspberry-pi-on-64-bit-linux/。为了获得提升，我在 raspberry pi 上使用了 apt install libboost-all-dev 并使用了这些文件。

#However, the file(GLOB...) allows for wildcard additions:

add_executable(MonitorApp ${SOURCES})

我该如何解决这个问题？
您正准备进行交叉编译，因此您安装了特定的工具链（编译器、库等）。然后您尝试使用普通的 boost 库，这些库是使用普通编译器构建的并且依赖于普通库。失败并不奇怪，是吗？
我不知道是否有简单的方法，但是使用您的编译器和用于 Raspberry Pi 的库从源代码编译 boost 应该可以解决问题。
