# Common Gotcha's
- If compiling all code togther (ie no sperate wolfssl library) than the -fPIC compiler flag should be used. Without using -fPIC in this build setup there could be unexpected failures.
- If compiling all code together (ie no separate wolfssl library) than the -fPIC compiler flag should be used. Without using -fPIC in this build setup there could be unexpected failures.
- If building with ARMv8 crypto extensions then the compiler flags "-mstrict-align -mcpu=generic+crypto" must be used.
- Check that enough stack and heap memory is set for the operations if a crash or stall happens.
