问题 I am unable to find clear instructions to install Google Protocol Buffers (including compiler) on Windows x64 platform. I went through the instructions README file for compiler and source: For Compiler: To install, simply place this binary somewhere in your PATH I added system variable to Path: PROTOC 'C:\dev_tools\protoc-2.4.1-win32' I am stuck on installing Protocol Buffers source using Cygwin. I tried following Unix instructions provided in the readme file: To build and install the C++

Is there a default return value of C++ functions? [duplicate]

问题 This question already has answers here : Why does flowing off the end of a non-void function without returning a value not produce a compiler error? (9 answers) Closed 6 years ago . I am surprised that a file containing the following lines of code is successfully compiled and linker produces an executable. I thought that all functions, except main , must have a valid return statement unless the return type is void . int foo(){} double bar(){} int main(){} What am I missing? 回答1: I thought

在win10环境下安装Cygwin，可以GCC编译

参考博客： http://www.cnblogs.com/hchacha/p/7147603.html 1. 上述网址提供了setup-x86_64.exe，用于安装 Cygwin 2. 我在安装时，选择了如下网址去下载mirros： 3. 现在的cywin默认是最小化安装，但并不包括Gcc，如果要使用gcc,g++,make,gdb工具，是需要选择这些包的 gcc-core、gcc-g++、make、gdb、binutils，五个包都在Category下的Devel下 。 4. 后来，我又安装了 git vim openssh 3个组件，安装流程如下： 点开setup-x86.exe，一路Next：选择在线安装 -> 填写根路径cygwin -> 填写下载的临时安装文件保存路径cygwinsetup -> 选择镜像站点(选国内163或阿里云) ->点击列表ALL 然后通过search查找，将旁边的Default将其切换到Install状态 ->继续一路Next完成安装 来源： oschina 链接： https://my.oschina.net/u/4311561/blog/3552417

win10下安装Cygwin配置gcc编译环境

由 China☆狼群 提交于 2021-02-02 12:20:43
首先要说明的是，我个人安装cygwin的用途是为了使用kenlm工具训练通及语言模型。 注： 统计语言模型工具有比较多的选择，目前比较好的有srilm以及kenlm，其中kenlm比srilm晚出来，训练速度也更快，而且支持单机大数据的训练。 因为使用该工具在Linux环境下比较方便，我是win10系统，所以需要使用cywin 64模拟linux环境 （先确保linux环境已经按照1.36.0的Boost和zlib。） 然后gcc版本需要是4.8.2及以上。 之后出现的界面，默认为第一个选项，意思是从网络下载并安装（从官网下载的不是完整安装包，只是安装引导程序） 之后都没什么问题，就默认下一步就ok了 然后会出现一个界面，ustc是中科大的镜像，neusoft是东软的镜像下载速度较快，当然也可也选香港的（一个hk的什么网站，很好找）。 在搜索框出处分别搜索 gcc-core、gcc-g++、make、gdb、binutils，以上所有项目都在 devel 文件夹下。点击想要下载的包后面的skip即可。 然后点击下一步。 将安装目录下的 bin目录 添加到 Path 环境变量。我用的是 windows 10，添加环境变量的具体方法自行百度。 最后在terminal中 输入gcc -v + enter，出现如下界面即为安装成功。 来源： oschina 链接： https://my

Windows下Cygwin 的安装

由 早过忘川 提交于 2021-02-02 02:54:51
在安装时， 单击加号 (+) 展开对应的类别；单击 “循环” 标志在 Skip（忽略此包）和包的所有可用版本之间循环。如果 Cygwin 提供一个实用程序的多个版本，应该选择满足您的需求的实例。顺便说一下，如果选择 B 列，就会下载二进制包；选择 S，也会下载源代码。 我用的windows xp系统，安装完Cygwin之后，点击图标，出现cygiconv-2.dll找不到的错误。 在网上下载一个 cygiconv-2.dll组件之后，并把它放入C:\WINDOWS\system32目录下。然后就OK了。 在安装完Cygwin 之后，点击Cygwin，输入基本命令ls等，出现Command not found。 原因是没有设置环境变量。 只需将Cygwin.bat文件修改为： @echo off set CYGWIN=tty notitle glob set PATH=%PATH%;d:/cygwin/bin;d:/cygwin/sbin;d:/cygwin/usr/bin;d:/cygwin/usr/sbin;d:/cygwin/usr/local/bin set LD_LIBRARY_PATH=d:/cygwin/lib;d:/cygwin/usr/lib;d:/cygwin/usr/local/lib d: chdir d:\cygwin\bin bash --login -i
