@xiedapao Presumably there are a zillion other errors of that same form when you built?

@xiedapao Would you mind pasting the output of the following command as run from the root of go-filecoin?

cat proofs/rust-fil-proofs/filecoin-proofs/build.rs | grep framework

Yeah, that's a bug that was fixed upstream (in rust-fil-proofs) but hasn't yet been deployed to go-filecoin. I will fix that right now.

@xiedapao [filecoin mining]
The libfilecoin_proofs.a file has a few dynamic dependencies - things we can't link in statically, like glibc - and the linker flags have to been updated manually. Unfortunately, rust-fil-proofs CircleCI build doesn't try to link the libfilecoin_proofs.a file, so we don't know when we get the linker flags wrong until we've already updated the go-filecoin submodule SHA.

@xiedapao [filecoin mining]
I believe that a solution to this problem is that the rust-fil-proofs CircleCI build needs to be modified to link the libfilecoin_proofs.a archive file to a dummy C program using the same pkg-config file which go-filecoin uses.
