Lately I came across this error while cross-compiling php with opcache enabled. Here is a short log:
checking whether to enable Zend OPcache support... yes
checking for mprotect... yes
checking for sysvipc shared memory support... no
checking for mmap() using MAP_ANON shared memory support... no
checking for mmap() using /dev/zero shared memory support... no
checking for mmap() using shm_open() shared memory support... no
checking for mmap() using regular file shared memory support... no
checking "whether flock struct is linux ordered"... configure: error: in `/opt/php/php-7.0.9':
configure: error: cannot run test program while cross compiling
See `config.log' for more details
How can I do to resolve it? Any piece of information is much appreciated.
