Main Differences

• a lot of functions and structures were renamed to avoid namespaces conflicts you can check in patchs dir
• some cast were added to make code valid in C++ and C
• The flag BR_ENABLE_INTRINSICS its set to 1 by default to allow single unit compilation

Micro Client Example

just for testing , you have in micro_client_sample a micro https client example, put the BearSSLSingleUnitOne.c in the same folder and you can compile with:

gcc micro_client_sample/main.c -o client.o

and you can test with

 ./client.o example.com 443

Note that these example was taken from the original BearrSSL samples page and the BearSSLTrustedAnchors.h was taken from the oficial arduino Github Organization

Building From Scratch

if you want to build the hole project from scracth you must have diff,patch and Darwin on version 0.016 clone the repon and type:

 darwin run_blueprint --mode folder build/ update_bear create_patch build generate_release 

the build code its located in build and uses Darwin on blueprint mode to build the project
