Symbol collision with openssl #21

Closed paulhauner closed 4 years ago

paulhauner commented 4 years ago

I've been working to create portable versions of Lighthouse, which has meant vendoring openssl as a static library.

error: linking with `cc` failed: exit code: 1

I can resolve this issue and produce a binary if I use the following commit of blst: https://github.com/sigp/blst/commit/284f7059642851c760a09fb1708bcb59c7ca323c. This is basically s/sha256_block_data_order/blst_sha256_block_data_order across this project.

Linking is not my domain, so I open to more elegant solutions that my previous commit. Thank you :)

Resolved. Thanks for report!
