What is the proper way to build and call a specific version of solidity?

Question

I am getting the following error from solc:

Error: Source file requires different compiler version (current compiler is 0.4.11-develop.2017.6.22+commit.68ef5810.Darwin.appleclang - note that nightly builds are considered to be strictly less than the released version
pragma solidity 0.4.11;
^---------------------^

In order to build solc, I:

1. cloned the solidity repository,
2. ran git checkout v0.4.11 which successfully got the tag/v0.4.11. 3. completed the build process

3. made sure solc was in my path

   solc --version
   solc, the solidity compiler commandline interface
   Version: 0.4.11-develop.2017.6.22+commit.68ef5810.Darwin.appleclang
   

So, that is the v0.4.11 release, but the version number has today's date in it. Is that the source of the error?

System is macOS Sierra 10.12.5.

Answer 1

I solved my problem by RTFM. Mac users should install using Homebrew.

From Installing Solidity

brew update 
brew upgrade
brew tap ethereum/ethereum
brew install solidity
brew linkapps solidity

If you need a specific version of Solidity you can install a Homebrew formula directly from Github.

To Install specific version of solidity, use :

npm install -g solc@0.4

This will install solidity compiler 0.4.26 (latest on that version), globally.

or

npm install -g solc@0.5

Then

$ solcjs --version
> 0.4.26+commit.4563c3fc.Emscripten.clang
