codeblocks编译出错问题的解答！（编译c++或者c程序）典型错误：
execution of 'mingw32-g++.exe ……faile！
codeblocks cannot exec `cc1plus': No such file or directory
出现这样的错误，都是因为编译器没安装成功，或者没有设置好！
从设置过程就可以知道有没有安装g++编译器。
设置⽅法：Settings——Compiler…
⼀般默认compiler是GNU GCC Compiler
点进Toolchain executables，下⾯三项中，最好点进去重新选择⼀遍！
如果没有安装mingw（gcc、g++）编译器，选进去的时候就不到mingw32-g++.exe。
如此就说明没有安装mingw，可以单独下载mingw（download.csdn/detail/jingmiaa/9588535）
，安装，然后重新设置，在mingw安装⽬录下可以到mingw32-g++.exe。
（c++代码，编译器就是以下默认的三个，有些⽤的gcc⽽不是g++，编译纯C++就不通过。）
（纯c代码，以下三项全部选：。）
可以参考以下⽹友的问题与答案：
问题：
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)---------------
< -Wall -g  -c
C:\Users\jody\codeblocks\testc3\TestC3\main.c -o obj\Debug\main.o
mingw32-g++.exe  -o bin\ obj\Debug\main.o    Execution
of 'mingw32-g++.exe  -o bin\ obj\Debug\main.o' in
'C:\Users\jody\codeblocks\testc3\TestC3' failed.
Why is it trying to run mingw32-g++.exe as well ? (And if it shouldn't be doing this, how can I configure it not to?)
答案：
gnu编译器 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 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:
and mingw32-g++.exe are just tool driver programs. When invoked with compilation options for .c files, 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 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
OK out of Settings and rebuild your project.
