t_local_cache_threading.c:85:12: error: incompatible pointer to integer conversion

[dawesc]

Problem:

On MacOS using Homebrew I'm unable to compile with the following error:

[ 80%] Building C object tests/CMakeFiles/test_local_cache_threading.dir/integration/t_local_cache_threading.c.o
aws-encryption-sdk-c/tests/integration/t_local_cache_threading.c:85:12: error: incompatible pointer to integer conversion returning 'aws_thread_id_t' (aka 'struct _opaque_pthread_t *') from a function with result type 'unsigned long' [-Wint-conversion]
    return aws_thread_current_thread_id();
           ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1 error generated.

Solution:

I propose to forcibly cast to the return type to unsigned long.

Out of scope:

Nothing
