* doc: crypto/secp256k1 GMP dependency package name.Noel Maersk2015-04-231-1/+4
| | | | | | | | | | | | | | Linux build documentation is mostly geared towards Ubuntu 14.04 (LTS). Appropriate package is called `libgmp-dev` there. Note that on pristine installations building `geth` with godep will fail because this header is missing. This is not documented in the top-level README, but is on the wiki: https://github.com/ethereum/go-ethereum/wiki/Installation-Instructions-for-Ubuntu#building-geth-command-line-client That page recommends `libgmp3-dev`, which ATM provides same version as `libgmp-dev`.
