Eclipse CDT error: Unable to compile

问题:

I tried to run a simple Hello world program. I am getting this error when I try to build it. What does it mean and how do I resolve it? I am using Windows 7 and I have MinGW and MSys in the %PATH%.

**** Build of configuration Debug for project learn ****

**** Internal Builder is used for build               ****

Code:

    std::cout << "Hello, world!" << std::endl;
    return 0;
}

My %PATH% is:

I am able to run g++ from cmd:

C:\Users\Hari>g++ --version

I found the same problem with a C HelloWorld invoking the MinGW gcc compiler. After quite a bit of experimentation, I have found that the MinGW binutils package is to blame! The latest one doesn't play nice with CDT for some reason. Use this one instead and it will work :)

binutils-2.21-2-mingw32-bin.tar.lzma

NOTE: versions 2.21-3 and later seem to have the problem.

Additionally, the latest GDB 7.3 seems to hang too. Use this one:

gdb-7.2-1-mingw32-bin.tar.lzma

Happy coding :)

PS: I don't even have MinGW or MSYS in the path. As long as MinGW is in C:\MinGW things seem to magically work.

Try rebooting your system after setting your environment. Please refer to here:

CreateProcess: No such file or directory

How did you create the project? Start with the New->C++ Project. Then under Executable pick the "Hello World C++ Project". On the Toolchains I pick the MinGW GCC toolchain but it's possible you don't have that installed. At any rate this creats a fully compilable executable that makes a good starting point for learning. It puts all the include directories, library paths etc in the project settings.

I had similiar problem. Just deleted "C:\MinGW\bin" from the PATH, reinstalled MinGW and it worked. Ecllipse or CLion don't need PATH to be set. CLion even warns that "C:\MinGW\bin" should not be in the PATH.

I used an artifice. I have installed the Dev-Cpp and within it comes installed Mingw32. I copied the Mingw32 to directory c: and rename the mingw32 to c:\MinGW and include to %PATH%. It worked very well.
