# Itcoin
#
# This script configures the build for itcoin-core. It can be used both on bare
# metal and inside a Docker container.
#
# Normally, the system's default C/C++ compilers are used. If you want to use
# a specific compiler, define the environment variables CC and CCX before
# calling the script.
#
# Please note that this script takes care of a bug in secp256k1's configure
# script (at least as of 2022-07-08), that needs to set both CC and
# CC_FOR_BUILD.
#
# EXAMPLE with custom compilers:
#     $ export CC=/path/to/c-compiler
#     $ export CXX=/path/to/c++-compiler
#     $ ./configure-itcoin-core.sh

# NB: The `--enable-debug` configure option included here adds
#     `-DDEBUG_LOCKORDER` to the compiler flags. Hence, the flag
#     -DDEBUG_LOCKORDER has to be used also in the compilation of itcoin-pbft,
#     in order to prevent an unpredictable behaviour.
#     See developer-notes.md for more information on DEBUG_LOCKORDER.
