# This script was tested on Linux and MacOS hosts, where it can be used
# to build native libsecp256k1 binaries.

# It can also be used to cross-compile to Windows:
# $ sudo apt-get install mingw-w64
# For a Windows x86 (32-bit) target, run:
# $ GCC_TRIPLET_HOST="i686-w64-mingw32" ./contrib/make_libsecp256k1.sh
# Or for a Windows x86_64 (64-bit) target, run:
