`./wolfssl-arduino.sh`
Step 2: Copy the directory wolfSSL that was just created to:
`~/Documents/Arduino/libraries/` directory so the Arduino IDE can find it.
Step 2: Edit `<wolfssl-root>/IDE/ARDUINO/wolfSSL/wolfssl/wolfcrypt/settings.h` uncomment the define for `WOLFSSL_ARDUINO`
If building for Intel Galileo platform also uncomment the define for `INTEL_GALILEO`.
Step 3: Edit `<arduino-libraries>/wolfSSL/user_settings.h`
If building for Intel Galileo platform add: `#define INTEL_GALILEO`.
Add any other custom settings, for a good start see the below in wolfssl root.
(See wolfssl/IDE/ROWLEY-CROSSWORKS-ARM/user_settings.h)
Step 4: If you experience any issues with custom user_settings.h see the wolfssl
porting guide here for more assistance: https://www.wolfssl.com/docs/porting-guide/
Step 5: If you still have any issues contact support@wolfssl.com for more help.
