solc-builds

The main purpose of the repo is to provide MacOS aarch64 binaries for roynalnaruto/svm-rs and eventually for gakonst/foundry.

Pre-requisite

Z3 is required to build solc with SMT solver support.

• Download Z3 (version 4.8.17 should be compatible with solidity >= 0.8.21, while 4.12.1 is required for solidity >= 0.8.22) and unzip

$ wget https://github.com/Z3Prover/z3/releases/download/z3-4.12.1/z3-4.12.1-arm64-osx-11.0.zip
$ unzip z3-4.12.1-arm64-osx-11.0.zip && cd z3-4.12.1-arm64-osx-11.0

• Copy to /usr/local

$ cp bin/libz3.a /usr/local/lib
$ cp bin/z3 /usr/local/bin
$ cp include/* /usr/local/include

Build Instructions

The following steps are meant to be run on a MacOS machine with the M1 chip:

• Clone the solidity repository
• Checkout to the release tag of interest:

$ git checkout tags/v0.8.15

• Build the solc binary for the above release tag

$ ./scripts/build.sh

• The binary solc is then found under the ./build/solc/ directory
• Get the SHA-256 checksum for the binary

$ shasum -a 256 ./build/solc/solc
