Ubuntu sys/byteorder.h & sys/endian.h 缺失，同时构建 MySQL 连接器/C++

  • 772

请记住，在从源代码构建方面我是初学者（尝试了几次，几乎总是失败）。

我正在尝试为运行 Ubuntu 19 的 Raspberry Pi 3b 构建 MySQL 连接器/C++ 8。我按照官方说明安装了所有先决条件（不是 100% 确定是否codecvt_utf8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--target install直接添加了 - 不确定这是否是一个问题）：

cmake .
cmake --build . --target install --config Release

由于以下原因，它失败了 AFAIK：

CMakeFiles/CMakeTmp/CheckIncludeFile.c:1:10：致命错误：sys/endian.h：没有这样的文件或目录

CMakeFiles/CMakeTmp/CheckIncludeFile.c:1:10：致命错误：sys/byteorder.h：没有这样的文件或目录

我查过了/usr/include，没有目录sys。endian.h直接在顶层，根本byteorder.h不存在。

为什么有些文件不见了？

如前所述，该sys目录位于 Ubuntu 上的不同位置。所以我运行了这个：

ln -s /usr/include/aarch64-linux-gnu/sys /usr/include/sys

但是丢失的文件实际上也不在该目录中。

跑步

find /usr/include -type f -name endian.h
find /usr/include -type f -name byteorder.h

显示，文件实际上在/usr/include/aarch64-linux-gnu/bits/endian.hand中/usr/include/aarch64-linux-gnu/asm/byteorder.h，我应该链接那些吗？似乎是个坏主意。

    似乎 C++ 编译器内存不足。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

    （这被称为“源外”构建）

    如果失败，并且 Pi 仍然没有足够的内存，请使用该raspi-config工具（以 root 身份运行）调整 Pi 的内存分配，尽可能少地分配给 GPU，并禁用图形登录，以尝试增加用于编译的空闲内存。然后，重新启动以使更改生效，然后像从控制台一样构建。如果一切顺利，您可以再次使用raspi-config将之前修改的设置调整回其原始值。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 机器上进行交叉编译。有关如何使用 为 Pi 构建交叉编译工具链crosstool-ng，然后使用它构建 CMake 项目的指南，可在此处找到：https ://blog.kitware.com/cross-compiling-for-raspberry-pi/ .
