gcc7 stdlib.h: No such file or directory #include_next <stdlib.h>
Using debian 10 (unstable) and gcc/g++ 7 I still get the following error compiling OpenCV
/usr/include/c++/7/cstdlib:75:15: fatal error: stdlib.h: No such file or directory #include_next <stdlib.h>
Switching precompiled headers off or patching CMAKE file (opencv/cmake/OpenCVPCHSupport.cmake) by replacing -isystem option with -I did not help. Any one know any work around for this problem. My complete CMAke configuration is as follow:
