Linking error with MinGW and imgcodecs_300

edit

Hi, I am trying to install OpenCV on Windows 7 using MinGW. However, when I run

mingw32-make

I get the following error:

[ 36%] Linking CXX shared library ..\..\bin\libopencv_imgcodecs300.dll
Error running link command: The system cannot find the file specified
modules\imgcodecs\CMakeFiles\opencv_imgcodecs.dir\build.make:513: recipe for tar

or 2

mingw32-make: *** [all] Error 2

I don't know what the problem might be. I have followed all the steps for the installation. Thank you very much for your help.
