Hey @komalklr, thanks for the feedback. This is a legacy version of the Truebit Toolchain which in not currently maintained. What sort of task are you trying to build?

ok..I am trying to integrate bulletproofs(Rust) with Truebit.Can I get the current version.I tried building emscripten-module-wrapper and ocaml-offchain from source but that is also giving some dependency error.
Thanks
