我想配置 Eclipse(或 Codeblocks)，以便在编写通行证时至少可以利用 Intellisense(即使无法直接从 Eclipse 中构建通行证)。 更新:在 Eclipse 中启用基于解析的提案后，我至少获得了一些智能感知(详情如下)
到目前为止，我已经将 Eclipse 配置为使用 clang 来编译简单的 C++ 程序。
为了获得 LLVM pass 的智能感知，我添加了 /usr/local/include到 Includes 目录和尝试过的代码:
#include <iostream>
#include <llvm/IR/Function.h>
using namespace std:
int main() {
cout << "Hello World" << endl;
return 0;
}
它不会在 #include <llvm/IR/Function.h> 上失败本身(即它可以找到这个头文件)，但是在包含后续文件后，给我
/usr/local/include/llvm/Support/DataTypes.h:58:3: error: "Must #define __STDC_LIMIT_MACROS before #including Support/DataTypes.h"
关于如何让它至少给我智能感知的任何指示？

更新: Eclipse 确实给了我智能感知(至少是其中的一部分)，我不得不在 Window -> Preferences -> 中检查 Parsing-based Proposals C/C++ -> Editor -> Content Assist -> Advanced(默认未勾选)。
最佳答案
这不是直接回答问题，但可以确保您拥有一个正常工作的构建环境。它特定于代码块。
首先查看llvm的源码树(直接取自入门guide):
git clone http://llvm.org/git/llvm.git
cd llvm/tools
git clone http://llvm.org/git/clang.git
cd ..
cd projects
git clone http://llvm.org/git/compiler-rt.git
git clone http://llvm.org/git/libcxx.git
git clone http://llvm.org/git/libcxxabi.git
git clone http://llvm.org/git/test-suite.git
git clone http://llvm.org/git/openmp.git
删除任何你不喜欢的东西。
然后在llvm目录外创建一个目录:
cd ..
mkdir build
将目录 (cd) 更改到那里并运行:
cd build
cmake -g "CodeBlocks - Unix Makefiles" <your configure options> ../llvm
假设 llvm 共享根路径，否则将 ../llvm 行更改为正确的路径。然后在 code::blocks 中将其作为现有项目打开。
如果一切顺利，您的构建环境设置正确并且代码完成应该可以工作。

我的瘦服务器配置了nginx，我的ROR应用程序正在它们上运行。在我发布代码更新时运行thinrestart会给我的应用程序带来一些停机时间。我试图弄清楚如何优雅地重启正在运行的Thin实例，但找不到好的解决方案。有没有人能做到这一点？ 最佳答案 #Restartjustthethinserverdescribedbythatconfigsudothin-C/etc/thin/mysite.ymlrestartNginx将继续运行并代理请求。如果您将Nginx设置为使用多个上游服务器，例如server{listen80;server
我有一个在Linux服务器上运行的ruby脚本。它不使用rails或任何东西。它基本上是一个命令行ruby脚本，可以像这样传递参数:./ruby_script.rbarg1arg2如何将参数抽象到配置文件(例如yaml文件或其他文件)中？您能否举例说明如何做到这一点？提前谢谢你。 最佳答案 首先，您可以运行一个写入YAML配置文件的独立脚本:require"yaml"File.write("path_to_yaml_file",[arg1,arg2].to_yaml)然后，在您的应用中阅读它:require"yaml"arg
我已经在Sinatra上创建了应用程序，它代表了一个简单的API。我想在生产和开发上进行部署。我想在部署时选择，是开发还是生产，一些方法的逻辑应该改变，这取决于部署类型。是否有任何想法，如何完成以及解决此问题的一些示例。例子:我有代码get'/api/test'doreturn"Itisdev"end但是在部署到生产环境之后我想在运行/api/test之后看到ItisPROD如何实现？ 最佳答案 根据SinatraDocumentation:EnvironmentscanbesetthroughtheRACK_ENVenvironm
有没有办法在这个简单的get方法中添加超时选项？我正在使用法拉第3.3。Faraday.get(url)四处寻找，我只能先发起连接后应用超时选项，然后应用超时选项。或者有什么简单的方法？这就是我现在正在做的:conn=Faraday.newresponse=conn.getdo|req|req.urlurlreq.options.timeout=2#2secondsend 最佳答案 试试这个:conn=Faraday.newdo|conn|conn.options.timeout=20endresponse=conn.get(url
我有一个存储主机名的Ruby数组server_names。如果我打印出来，它看起来像这样:["hostname.abc.com","hostname2.abc.com","hostname3.abc.com"]相当标准。我想要做的是获取这些服务器的IP(可能将它们存储在另一个变量中)。看起来IPSocket类可以做到这一点，但我不确定如何使用IPSocket类遍历它。如果它只是尝试像这样打印出IP:server_names.eachdo|name|IPSocket::getaddress(name)pnameend它提示我没有提供服务器名称。这是语法问题还是我没有正确使用类？输出:ge
我想获取模块中定义的所有常量的值:moduleLettersA='apple'.freezeB='boy'.freezeendconstants给了我常量的名字:Letters.constants(false)#=>[:A,:B]如何获取它们的值的数组，即["apple","boy"]？ 最佳答案 为了做到这一点，请使用mapLetters.constants(false).map&Letters.method(:const_get)这将返回["a","b"]第二种方式:Letters.constants(false).map{|c
我安装了ruby版本管理器，并将RVM安装的ruby实现设置为默认值，这样'哪个ruby'显示'~/.rvm/ruby-1.8.6-p383/bin/ruby'但是当我在emacs中打开inf-ruby缓冲区时，它使用安装在/usr/bin中的ruby。有没有办法让emacs像shell一样尊重ruby的路径？谢谢! 最佳答案 我创建了一个emacs扩展来将rvm集成到emacs中。如果您有兴趣，可以在这里获取:http://github.com/senny/rvm.el
假设我有这个范围:("aaaaa".."zzzzz")如何在不事先/每次生成整个项目的情况下从范围中获取第N个项目？ 最佳答案 一种快速简便的方法:("aaaaa".."zzzzz").first(42).last#==>"aaabp"如果出于某种原因你不得不一遍又一遍地这样做，或者如果你需要避免为前N个元素构建中间数组，你可以这样写:moduleEnumerabledefskip(n)returnto_enum:skip,nunlessblock_given?each_with_indexdo|item,index|yieldit
我目前正在使用以下方法获取页面的源代码:Net::HTTP.get(URI.parse(page.url))我还想获取HTTP状态，而无需发出第二个请求。有没有办法用另一种方法做到这一点？我一直在查看文档，但似乎找不到我要找的东西。 最佳答案 在我看来，除非您需要一些真正的低级访问或控制，否则最好使用Ruby的内置Open::URI模块:require'open-uri'io=open('http://www.example.org/')#=>#body=io.read[0,50]#=>"["200","OK"]io.base_ur
如何在Ruby中获取BasicObject实例的类名？例如，假设我有这个:classMyObjectSystem我怎样才能使这段代码成功？编辑:我发现Object的实例方法class被定义为returnrb_class_real(CLASS_OF(obj));。有什么方法可以从Ruby中使用它？ 最佳答案 我花了一些时间研究irb并想出了这个:classBasicObjectdefclassklass=class这将为任何从BasicObject继承的对象提供一个#class您可以调用的方法。编辑评论中要求的进一步解释:假设你有对象
