如何处理Eclipse CDT + Cygwin？ [英] How to deal with Eclipse CDT+Cygwin?

问题描述

最近我安装了Eclipse Indigo Service Release 2（针对JAVA EE）并安装了CDT 8。然后我用最新版本的gcc，g ++，gdb，make，binutils，automake等安装Cygwin。环境变量PATH正确。

Recently I installed Eclipse Indigo Service Release 2(for JAVA EE) and installed CDT 8 online.Then I installed Cygwin with gcc,g++,gdb,make,binutils,automake,etc at the latest version.I had also made the environment variable PATH correct.

创建一个新的C ++项目（使用Cygwin GCC工具链）是很好的，但是在输入HelloWorld程序后，它会显示许多错误和警告。

Making a new C++ project(using Cygwin GCC toolchain) is just fine,but after typing a HelloWorld program,it shows lots of errors and warings.

使用外部构建器时，错误显示

When using external builder,in error it shows

无法运行程序make：？。

"Cannot run program "make": ?????????¨?".

当使用内部构建器时， / p>

When using internal builder,in conclose it shows

g ++ -IC：\cygwin\lib\gcc\i686-pc-cygwin\4.5.3\include \c ++ -O0 -g3 -Wall -c -fmessage-length = 0 -o src\test_cpp.o ..\src\test_cpp.cpp

"g++ -IC:\cygwin\lib\gcc\i686-pc-cygwin\4.5.3\include\c++ -O0 -g3 -Wall -c -fmessage-length=0 -o src\test_cpp.o ..\src\test_cpp.cpp

错误：无法运行程序g ++：¨？

Error: Cannot run program "g++": ?????????¨?

生成错误，构建已停止

在Windows CMD和Cygwin Terminal，g ++和make都很好。

In both Windows CMD and Cygwin Terminal,g++ and make both work well.

找不到包含库，所以我必须添加路径C：\cygwin\lib\gcc\i686-pc-cygwin\4.5.3\include\c ++到项目属性 - > C / c ++ Building-> Settings.But之后，错误地，它仍然显示，

What's more,Eclipse can't find the including libraries,so I have to add the path C:\cygwin\lib\gcc\i686-pc-cygwin\4.5.3\include\c++ to the project properties->C/C++ Building->Settings.But after that, in error,it still shows,

'std'是不明确的

'std' is ambiguous '

'endl'无效的重载

Invalid overload of 'endl'

无法解析符号'cout'

Symbol 'cout' could not be resolved

在项目属性 - > C / C ++ Building->发现选项中，我将Discovery Profile范围设置为每个文件扫描器信息概要文件中的Configeration-wide和Discovery概要文件。 p>

In project properties->C/C++ Building->Discovery Options,I set the Discovery Profile scope as Configeration-wide and Discovery profile as GCC per file scanner info profile.

推荐答案

您必须设置Cygwin工具链，首先使用以下软件包安装Cygwin：

You have to setup a Cygwin toolchain, first of all install Cygwin with the following packages :

binutils
gcc
gcc-core
gcc-g++
gcc-mingw-core
gcc-mingw-g++
make

添加％cygwin％\bin 到您的PATH环境变量，然后打开Eclipse和Cygwin工具链将在您打开一个新的c / cpp项目向导时显示。

Add %cygwin%\bin to your PATH environment variable, then open Eclipse and Cygwin toolchain will be shown when you open a new c/cpp project wizard.
