CreateProcess: No such file or directory

According to Code::Blocks wiki, you need to add C:\MinGW\libexec\gcc\mingw32\MinGW-Version to your PATH. There is no need to restart, but you need to open another terminal in order to get the newest PATH settings.

For MinGW-w64, that's <mingw install directory>\libexec\gcc\x86_64-w64-mingw32\4.7.0\

So this is a stupid error message because it doesn't tell you what file it can't find.

Run the command again with the verbose flag gcc -v to see what gcc is up to.

In my case, it happened it was trying to call cc1plus. I checked, I don't have that. Installed mingw's C++ compiler and then I did.

I just had this problem.

In my case, the problem was due to problems when downloading the packages for GCC. The mingw-get program thought it finished the download, but it didn't.

I wanted to upgrade GCC, so I used mingw-get to get the newer version. For some reason, mingw-get thought the download for a particular file was finished, but it wasn't. When it went to extract the file, I guess it issued an error (which I didn't even bother to look -- I just ran "mingw-get update && mingw-get install mingw32-gcc" and left it there).

To solve, I removed gcc by doing "mingw-get remove mingw32-gcc" and also removed the package file (the one mingw-get didn't fully download), which was in the mingw cache folder ("C:\MinGW\var\cache\mingw-get\packages" in my system), then ran the install command again. It download and installed the missing parts of GCC (it had not fully downloaded the package gcc-core).

That solved my problem.

Interestingly enough, mingw-get was smart enough to continue the download of gcc-core even after me having deleted the package file in the cache folder, and also removed the package mingw32-gcc.

I think the more fundamental problem was that since gcc-core files were not installed, cc1 wasn't there. And gcc uses cc1. I guess that, when gcc tried to start cc1, it used CreateProcess somewhere passing the path of cc1, which was not the path of an existing file. Thus the error message.

I had a similar problem, caused by not installing the C++ compiler. In my case I was compiling .cpp files for a Python extension, but the compiler is first invoked as c:\mingw\bin\gcc.exe.

Internally, gcc.exe would notice it was asked to compile a .cpp file. It would try to call g++.exe and fail with the same error message:

gcc.exe: CreateProcess: no such file or directory
