mingw 构建 mysql-connector-c-6.1.9记录
1、准备工作
首先需要下载mysql-connector-c-6.1.9的源码，然后解压。
然后需要准备编译环境，这里我使用的是msys2(下载地址http://repo.msys2.org/distrib/x86_64/msys2-x86_64-20161025.exe)。
下载安装后执行下面命令：
# 先更新一下（这一步后面可能会报错，只需要关闭终端，再打开重新更新一下即可）
pacman -Syu
# 安装编译需要工具
pacman -S gcc make cmake
# 下面这句也可以不要
# pacman -S mingw-w64-x86_64-extra-cmake-modules
# 再安装一个vim，这个不是必须的
pacman -S vim
全部安装完成之后，即可进入下一步
2、生成makefile
进入解压后的源码目录
执行下面的命令生成`Makefile文件
# 先创建并进入一个构建目录
mkdir build && cd build
# 生成makefile
cmake -G"Unix Makefiles" ..
执行过程中报下面的错误
$ cmake -G"Unix Makefiles" ..
-- Running cmake version 3.6.2
System is unknown to cmake, create:
Platform/MINGW64_NT-6.2 to use this system, please send your config file to cmake@www.cmake.org so it can be added to cmake

CMake Error at configure.cmake:573 (MESSAGE):

这里提示是Platform/MINGW64_NT-6.2这个系统环境，cmake不知道怎么去创建构建脚本。这里提示让你把生成的CopyOfCmakeCache.txt文件发送到cmake@www.cmake.org，这里就不发了。
根据提示，打开configure.cmake文件，定位到573行，内容如下
IF(NOT HAVE_POSIX_TIMERS AND NOT HAVE_KQUEUE_TIMERS AND NOT WIN32)
MESSAGE(FATAL_ERROR "No mysys timer support detected!")
ENDIF()
既然这里判断出错，那就直接修改这里好了，在文件最前面前面加上下面语句
SET(WIN32 1)
# 后面不是必须的
SET(WIN64 1)
SET(WINDOWS 1)
重新运行cmake -G"Unix Makefiles" ..即可生成Makefile文件。
这样还不够，还需添加下面一句。具体的请看后面编译时候出现的问题描述
add_definitions(-DWIN32=1 -D_WIN32=1 -DWIN64=1 -DWINDOWS=1 -D__USE_W32_SOCKETS=1)
3、编译
编译过程并不是很顺利，中间遇到很多问题需要解决，这里简单的记录一下
问题1
直接执行make命令来生成，结果报如下错误：

解决办法：
直接打开my_winerr.c这个文件，可以看到这里是定义了windows系统返回错误码与System V错误码的一个对照表。
struct errentry
{
unsigned long oscode; /* OS return value */
int sysv_errno; /* System V error code */
};
static struct errentry errtable[]= {
{ ERROR_INVALID_FUNCTION, EINVAL }, /* 1 */
{ ERROR_FILE_NOT_FOUND, ENOENT }, /* 2 */
{ ERROR_PATH_NOT_FOUND, ENOENT }, /* 3 */
{ ERROR_TOO_MANY_OPEN_FILES, EMFILE }, /* 4 */
.... 后面省略 ...
**Windows的错误码定义都在WinError.h文件中，所以只需要修改my_winerr.c文件，在前面添加
#include <WinError.h>
即可。
问题2
继续make编译，报如下错误

这个错误的原因是因为c编译器不支持函数外动态声明变量和分配空间，但是这里都是宏，应该替换成了字面常量才对。
通过gcc -E预处理以下(预处理需要指定包含路径，这个可以去libmysql/CMakeFiles目录下找flags.cmake文件查看)，可以得到下面代码（为了方便，我把行数输出了）
7309 struct errentry
7310 {
7311 unsigned long oscode;

解决办法：
这里看到常数被__MSABI_LONG这个宏处理了一次，所以这里把这个宏给去掉即可。
在结构体数组初始化前后分别加上下面语句即可：
// 初始化前加上下面语句
#pragma push_macro("__MSABI_LONG")
#define __MSABI_LONG(x) x
// 初始化赋值
static struct errentry errtable[]= {
{ ERROR_INVALID_FUNCTION, EINVAL }, /* 1 */
{ ERROR_FILE_NOT_FOUND, ENOENT }, /* 2 */
.... 省略 ...
{ ERROR_NESTING_NOT_ALLOWED, EAGAIN }, /* 215 */
{ ERROR_NOT_ENOUGH_QUOTA, ENOMEM } /* 1816 */
};
// 初始化后加上下面语句
#undef __MSABI_LONG
#pragma pop_macro("__MSABI_LONG")
再次执行make即可。

两个警告就先不管了（找具体头文件）。这里后面的报错，应该是Vio这个结构体中的定义问题，需要找到其定义的位置。
可以找到相关的定义在mysql-connector-c-6.1.9-src/include/violite.h文件中的267到337之间（就是最后一部分）。
可以看到overlapped成员是否被定义，与_WIN32宏是否被定义有关。
看来是之前生成Makefile的时候没有把widnows下相关的宏定义给加上。
再次修改configure.cmake文件，添加下面语句
add_definitions(-DWIN32=1 -D_WIN32=1 -DWIN64=1 -DWINDOWS=1)
再次运行cmake -G"Unix Makefiles" ..生成编译脚本，然后运行make进行编译
以下的大部分错误，都是由于_WIN32这个宏导致的！！！

这次的问题提示很明确，就是fd_set和select函数多处声明冲突的问题。
这个是由于在mingw下有相关的socket定义的问题，这个可以看/usr/include/w32api/psdk_inc/_fd_types.h文件得知。
#ifndef ___WSA_FD_TYPES_H
#define ___WSA_FD_TYPES_H
#include <psdk_inc/_socket_types.h>

#define FD_SETSIZE 64
#endif

/* fd_set may have been defined by the newlib <sys/types.h>
* if __USE_W32_SOCKETS not defined.
*/
typedef struct fd_set
{
u_int fd_count;
SOCKET fd_array[FD_SETSIZE];
} fd_set;
可以看到注释中有if __USE_W32_SOCKETS not defined.一句，这里只需要将其加入Makefile中即可。
我直接修改的configure.cmake文件中之前添加的语句，如下：
add_definitions(-DWIN32=1 -D_WIN32=1 -DWIN64=1 -DWINDOWS=1 -D__USE_W32_SOCKETS=1)
再次生成编译脚本并执行make即可。
问题6
继续编译，又遇到如下问题
[ 9%] Building CXX object extra/yassl/CMakeFiles/yassl.dir/src/socket_wrapper.cpp.obj

这里是因为函数ioctlsocket的第三个参数&ready类型为long unsigned int*而不是需要的__ms_u_long* {aka unsigned int*}，直接强转即可。
这个很好解决，直接修改mysql-connector-c-6.1.9-src/extra/yassl/src/socket_wrapper.cpp文件中的118行 为如下:
// unsigned long ready = 0;
__ms_u_long ready = 0;

问题8
继续编译，将遇到一大堆重定义的问题，基本都来自于my_global.h文件中。
这是由于mingw的自带的头文件中与Widnows sSDK中的头文件中的一些定义有冲突（mingw把一些linux上的系统函数进行了实现），这里只需要判断后进行注释掉即可。
下面把有冲突的地方列出来。

Z:/mysql-connector-c-6.1.9-src/mysys_ssl/my_default.cc: 在函数‘size_t my_get_system_windows_directory(char*, size_t)’中:
Z:/mysql-connector-c-6.1.9-src/mysys_ssl/my_default.cc:1344:58: 错误：‘stricmp’在此作用域中尚未声明
if (count > 8 && stricmp(buffer+(count-8), "\\System32") == 0)
^
make[2]: *** [mysys_ssl/CMakeFiles/mysys_ssl.dir/build.make:114：mysys_ssl/CMakeFiles/mysys_ssl.dir/my_default.cc.obj] 错误 1
这里将stricmp改为strcasecmp即可。
