iOS Build Error 'sys/random.h' file not found

[Nailik]

When building on Mac OS for an iOS device there is an error in sqlite3.c (amalgamation file).

sqlite3.c fatal error: 'sys/random.h' file not found
#include <sys/random.h>

After removing the line, it builds and works.

The inclusion of the header file is guarded by the following preprocessor instruction:

#if defined(__APPLE__) && defined(__MAC_10_12)
#include <sys/random.h>
#endif

So, even though you are compiling for iOS both symbols seem to be defined, and the compiler therefore tries to include the header file sys/random.h.

You could try to modify the check as follows:

#if defined(__APPLE__) && defined(__MAC_10_12) && !defined(__IPHONE_OS_VERSION_MIN_REQUIRED)
#include <sys/random.h>
#endif

Most likely this will prevent the inclusion of the header file for the iOS build. Please let me know whether this works for you.

This fixed the issue!

Thanks for confirming. Commit a8c9e93 applies the fix.
