compile file on OSX platform

Hello!
While compile file on OSX platform, like this

[ 10%] Building CXX object CMakeFiles/blend.dir/src/poisson_solver.cpp.o

make[1]: *** [CMakeFiles/tests.dir/all] Error 2

Would you please tell me which step is wrong?

Hi,

will have a look at it, but this line

ld: can't open output file for writing: tests, errno=21 for architecture x86_64

rings a bell. Are you sure that the tests executable file is writable? It seems like the other examples compile fine.

Thanks for your reply, I am a new comer to opencv. Maybe the step to install opencv is wrong, i will uninstall opencv and try again.
