c++ - opencv_perf_stitching_Release.gch not generated by cmakefiles -

i trying configure opencv codeblocks got stuck during mingw32-make step, giving me error:

i unable resolve it!

i using windows 7 32bit

i met similar problem may caused cmd input limitation. cmd input limitation in win7 8000 characters , in case enough.

however in opencv build,one built component (opencv_perf_stitching_release) might break limition due long executed command.because of different folder length different users,the cutting point in executed command located @ unfixed position.their error messages totally distinctive.in example,i got message unrecognized command line option '-sse' doubt met same problem.

the simplest solutiuon reduce building folder level.in case,you can change install path c:/opecv/opencv/ c:/opencv/ , try again.
