C bindings examples

This folder holds tests (prefixed with t_) and examples for the C bindings.

Headers are located in include/ and the static and dynamic libraries in lib/.

To compile and run the example / test case, for example:

clang ethereum_bls_signatures.c -o ethereum_bls_signatures -I../include -L../lib -lconstantine

For the test case, you also need to link in -lgmp.

And depending on your setup you might need to specify where libconstantine.so can be found:

LD_LIBRARY_PATH=../lib ./ethereum_bls_signatures

(in case you compile and run from this directory).

The above of course assumes you have already compiled libconstantine.so (using nimble make_lib from the root directory of the repository).
