Hi, i want compile opencv for QT. i use this tutorial
@
http://www.laganiere.name/opencvCookbook/chap1s1_2.shtml
@
in step 8 i have this error:
@
C:\opencv_bin1>mingw32-make [ 0%] Building C object 3rdparty/zlib/CMakeFiles/zlib.dir/adler32.c.obj 'C:\Users' is not recognized as an internal or external command, operable program or batch file. 3rdparty\zlib\CMakeFiles\zlib.dir\build.make:53: recipe for target '3rdparty/zlib/CMakeFiles/zlib.dir/adler32.c.obj' failed mingw32-make[2]: *** [3rdparty/zlib/CMakeFiles/zlib.dir/adler32.c.obj] Error 1 CMakeFiles\Makefile2:269: recipe for target '3rdparty/zlib/CMakeFiles/zlib.dir/all' failed mingw32-make[1]: *** [3rdparty/zlib/CMakeFiles/zlib.dir/all] Error 2 makefile:112: recipe for target 'all' failed mingw32-make: *** [all] Error 2

i think it is from path variable but i don't see mistake in it.
any idea?

This has nothing to do with Qt. Qt is a library not a compiler.

OpenCV's CMake build script is trying to execute the command "C:\Users", which the command shell is correctly identifying is not an executable (it's a directory). Often these things are the result of spaces in paths and scripting that is not expecting that.

my address is
@C:\opencv_Bin@
so no space in path .

This has nothing to do with Qt. Qt is a library not a compiler.

Run "mingw32-make VERBOSE=1" and capture the output. Look for the actual command that is failing, and I expect it will become obvious.

i did that. this is output:

my opencv version is 2.44 and cmake is 2.6(because cmake 2.8.11 have error when i work with that).
i check that file adler32.c.obj doesn't exist. but this files is generated with Cmake and it must generate adler32.c.obj.
