典型錯誤：

execution of 'mingw32-g++.exe ……faile！

codeblocks cannot exec `cc1plus': No such file or directory

出現這樣的錯誤，都是因為編譯器沒安裝成功，或者沒有設置好！

從設置過程就可以知道有沒有安裝g++編譯器。

設置方法：Settings——Compiler…

一般默認compiler是GNU GCC Compiler

點進Toolchain executables，下面三項中，最好點進去重新選擇一遍！?

如果沒有安裝mingw（gcc、g++）編譯器，選進去的時候就找不到mingw32-g++.exe。

如此就說明沒有安裝mingw，可以單獨下載mingw（http://download.csdn.net/detail/jingmiaa/9588535），安裝，然后重新設置，在mingw安裝目錄下可以找到mingw32-g++.exe。

（c++代碼，編譯器就是以下默認的三個，有些用的gcc而不是g++，編譯純C++就不通過。）

（純c代碼，以下三項全部選：mingw32-gcc.exe。）

可以參考以下網友的問題與答案：

問題：

C Hello world: Code Blocks IDE, MinGW C compiler on windows

I can't get Code Blocks IDE to compile the hello world C program it creates when you create a new C project. I've installed MinGW and it was recognised by the IDE. But when I try to build I get the following output:

-------------- Build: Debug in TestC3 (compiler: GNU GCC Compiler)---------------mingw32-gcc.exe -Wall -g -c C:\Users\jody\codeblocks\testc3\TestC3\main.c -o obj\Debug\main.o mingw32-g++.exe -o bin\Debug\TestC3.exe obj\Debug\main.o Execution of 'mingw32-g++.exe -o bin\Debug\TestC3.exe obj\Debug\main.o' in 'C:\Users\jody\codeblocks\testc3\TestC3' failed.

Why is it trying to run?mingw32-g++.exe?as well as?mingw32-gcc.exe? (And if it shouldn't be doing this, how can I configure it not to?)

答案：

The?mingw32-gcc.exe?step is the compile step. The?mingw32-g++.exe?is the link step. This is the correct sequence and will work if your?mingw32?installation is "normal" and correct - where "normal" means you have installed the C++ as well as the C tools.

The link step is failing for you because?mingw32-g++.exe?cannot be executed, most likely because it does not exist on your?PATH. Try running?mingw32-g++.exe?at the command prompt to check. Look in the directory where?mingw32-gcc.exe?resides to see if?mingw32-g++.exe?is also there.

If your mingw32 installation has got broken somehow I suggest you uninstall and reinstall.

If you have?intentionally?installed only the C tools then that will explain what you are seeing, and it is easily fixed:

Both?mingw32-gcc.exe?and?mingw32-g++.exe?are just tool driver programs. When invoked with compilation options for?.c?files,?mingw32-gcc.exe?invokes the C compiler. When invoked with compilation options for?.cpp|cxx|...?files,?mingw32-g++.exe?invokes the C++ compiler. If either of them is invoked with linkage options then it invokes the linker.

Codeblocks by default configures?mingw32-g++.exe?to invoke the linker because it will do equally well for C projects, C++ projects and C/C++ projects, and it assumes you have the full C/C++ toolchain.

If you have not installed C++ tools and only want to build C, then you can use?mingw32-gcc.exe?to invoke both the C compiler and the linker. To configure this in the CodeBlocks IDE:

• Navigate?Settings?->?Compiler
• Ensure that the?Selected Compiler?is?GNU GCC
• Tab to?Toolchain executables
• Change?Linker for dynamic libs?from?mingw32-g++.exe?to?mingw32-gcc.exe
• OK out of?Settings?and rebuild your project.
