在构建MySQL连接器/C++时，缺少Ubuntu /byorder.h& sys/endian.h .h
在构建MySQL连接器/C++时，缺少Ubuntu /byorder.h& sys/endian.h .h
提问于 2019-12-30 18:08:30
请记住，我是一个初学者，当涉及到从源头构建(尝试了几次，几乎总是失败)。
我试图为运行Ubuntu 19的Raspberry 3b构建MySQL连接器/C++8。我遵循官方指示并安装了所有先决条件(不是100%确定codecvt_utf8是否存在)。
我正在构建没有JDBC和BOOST。我已经从源代码构建了OpenSSL 1.1.1。
我正在运行的命令(我直接添加了--target install -不确定这是否是一个问题)：
cmake .
cmake --build . --target install --config Release它失败了AFAIK，因此：
CMakeFiles/CMakeTmp/CheckIncludeFile.c:1:10:致命错误:sys/endian.h.h:没有这样的文件或目录CMakeFiles/CMakeTmp/CheckIncludeFile.c:1:10:致命错误:sys/byorder.h:没有这样的文件或目录
我检查了/usr/include，没有目录sys。endian.h直接位于顶层，而byteorder.h根本不存在.
为什么有些文件不见了？
正如前面提到的这里，sys目录位于Ubuntu上的不同位置。所以我做了这个：
ln -s /usr/include/aarch64-linux-gnu/sys /usr/include/sys但丢失的文件实际上也不在该目录中。
正在运行
find /usr/include -type f -name endian.h
find /usr/include -type f -name byteorder.h显示，这些文件实际上是在/usr/include/aarch64-linux-gnu/bits/endian.h和/usr/include/aarch64-linux-gnu/asm/byteorder.h中，我应该直接链接这些文件吗？似乎是个坏主意。

C++编译器似乎内存不足。使用make构建时，尝试指定1个线程，例如：
$ cd path/to/connector/source
$ mkdir build && cd build
$ cmake .. -DCMAKE_BUILD_TYPE=Release
$ make -j1(这称为“无源”构建)
如果失败了，而且Pi仍然没有足够的内存，请使用raspi-config工具(以根用户身份运行)来调整Pi的内存分割，给GPU提供尽可能少的内存，并禁用图形登录，尝试增加用于编译的空闲内存量。然后，重新启动以使更改生效，然后像从控制台构建一样。如果一切顺利，那么您可以再次使用raspi-config将先前修改的设置调整回原来的值。如果失败，那么您可能需要考虑在另一台具有更多内存的Linux机器上交叉编译。关于如何使用crosstool-ng为Pi构建交叉编译工具链，然后使用它构建CMake项目的指南可以在这里找到：https://blog.kitware.com/cross-compiling-for-raspberry-pi/。
