GRND_NONBLOCK is an undeclared identifier...?

[JunChung11]

Hello, I am trying to get through the first step of compiling on a macbook and I am getting the error stating that GRND_NONBLOCK from secp256k1/Random.cpp:130:56 is an undeclared identifier.
Am I doing something wrong? I am fairly new to running something as complicated as this so please bear with me :)

Here is the full output I received:

Hi sadly I don't have a Mac to check it.

Please follow one of those open issues to see if you can fix your problem:

For Mac

#244
#268
#137

[JunChung11]

Okay, so I looked through all three and they don't specifically mention how to solve the GRND_NONBLOCK error so I resorted to using the legacy. I've encountered the same errors mentioned in #268 so I updated as shown and was able to successfully compile.

The GRND_NONBLOCK error I ran into may be an issue on my side as the macbook I'm using is like 7 years old... idk, I'll have to continue to try and find out a way around that error.
