mpc-hc 编译

2：一般情况下，checkout完成后，找到mpc_hc工程中的Compilation.txt，然后按照进行配置编译就可以了；
每个版本的具体编译有些许不同，详细参考具体工程下的Compilation.txt；
注意：
1：一般情况下，工程中都会带有 bat文件，如果是xp系统一般没有问题，如果是win7系统一般需在头文件第一行添加cd /d %~dp0，如C:\MSYS\postinstall下的pi.bat文件，添加以
后才可以在win7上正常运行（很多工程或文件都有bat文件），如果有相关的就不用添加了；
2：如果Compilation.txt建议工程放到c盘，就先放到c盘，这样有利于配置，而且有利于bat文件运行（我换了其他路径bat文件就不可以运行了）；
3：一般Compilation.txt中 会有安装directx和MSYS_MinGW_GCC，所以自然需要配置到你的工程中，而Compilation.txt没有讲如果配置，你可以自己上网查如何配置；
现在最新版本中你给的编译文件是：mpc-hc/docs/Compilation.md
//2017.12;
现在MPC-hc 用的是MSYS2进行编译的，具体的区别自行百度；
具体Windows上配置MSYS2的方法同理在Compilation.txt会有；

//安装make
pacman -S make
//安装git
pacman -S git
Preparing the GCC environment
-
Download MSYS2 from http://www.msys2.org/. If you are on a 64-bit Operating System, which you should be, get the 64-bit version.
-
Install it on
C:\MSYS\. You can always install it somewhere else, but these instructions assume the aforementioned place. -
Run
msys2_shell.bat(if you didn't use the installer you must restart MSYS2 after first run). -
Install the needed software by running these commands:
pacman -Syu pacman -Su pacman -S make pkg-configNote that this is the bare minimum, you can install more packages that can be useful to you.
-
Download YASM and save it as yasm.exe in
C:\MSYS\usr\bin:- 32-bit: http://www.tortall.net/projects/yasm/releases/yasm-1.3.0-win32.exe
- 64-bit: http://www.tortall.net/projects/yasm/releases/yasm-1.3.0-win64.exe (Recommended)
- 注意：这里需要修改名字，取消-1.3.0-win64；
-
Download and extract MinGW to
C:\MSYS\mingw\from http://files.1f0.de/mingw/ (you might use the one that ships with MSYS2, but we recommend this one) 说明：其实这里也可手动下载安装GCC：可以忽略这一步，安装上面的下载替换就可以了，下载gcc： 参考这里：
https://blog.csdn.net/qiuzhiqian1990/article/details/56671839，我们先通过命令pacman -Ss gcc查询完整的gcc包名；
pacman -S msys/gccpacman -S gcc -
-
Create a file named build.user.bat in
C:\mpc-hc\containing the following entries, adapted for your system:@ECHO OFF SET "MSYSTEM=MINGW32" SET "MPCHC_MSYS=C:\MSYS" SET "MPCHC_MINGW32=%MPCHC_MSYS%\mingw" SET "MPCHC_MINGW64=%MPCHC_MINGW32%" REM You can set `MSYS2_PATH_TYPE` here or in environment variables so that Git is properly added to your `PATH` REM SET "MSYS2_PATH_TYPE=inherit" REM `MPCHC_GIT` is optional to set if you chose to add it in `PATH` when installing it and have set `MSYS2_PATH_TYPE` SET "MPCHC_GIT=C:\Program Files\Git" REM Optional, if you plan to modify the translations, install Python 2.7 or set the variable to its path SET "MPCHC_PYTHON=C:\Python27" REM Optional, If you want to customize the Windows SDK version used, set the variable SET "MPCHC_WINSDK_VER=8.1"
NOTES
- For Visual Studio 2017, we will try to detect the VS installation path automatically. If that fails you need to specify the installation path yourself. For example:
SET "MPCHC_VS_PATH=%ProgramFiles(x86)%\Microsoft Visual Studio\2017\Community\" - If you installed the MSYS/MinGW package in another directory you will have to use that path in the previous steps.
- If you don't have Git installed then the revision number will be a hard-coded one, like 1.6.3.0.
这里顺便提一下另一个俄国版本的MPC-be；
具体的过程和MPC-hc差不多，但是还是用的MSYS编译，还在维护；

msys2 获取windows环境变量：
之前的msys可以默认启动获取windows环境变量，但是msys2不可以默认获取windows环境变量了；
当然可以启动以后，通过export 设置临时环境变量，和cmd通过set 设置临时环境变量；
访问windows PATH环境变量
from：https://www.cnblogs.com/wswind/p/10650126.html
三种方法选择一个就可以：
- msys2_shell.cmd 中取消一行的注释：set MSYS2_PATH_TYPE=inherit
- 调用msys2_shell.cmd时使用-use-full-path参数
- 在windows系统的环境变量中添加 MSYS2_PATH_TYPE=inherit
