Why is this needing a specific version while 0.5.x doesn't?

This gets a little beyond my C++ knowledge, but iirc, something changed with the boost versions used recently, and if you build this version of Solidity with the latest version of boost, you get errors. When I researched those errors, it seemed that the change happened in recent boost versions, this is the closest Homebrew version of boost available that works with compiling this version of Solidity. You can try it if you like and see what I mean, but this fixed those build errors.

I don't know - 1.60 sounds a little old, too...

Well the Solidity cmake does check for the minimum supported version so this should be safe.

Keep in mind this is compiling 0.4.x which assumed 1.54 as a minimum.

@chriseth and @axic These are sadly the version available - https://formulae.brew.sh/formula/boost
I couldn't get a build to work with the 1.69 version, but I am not sure why, I can share logs if need be. Or we know of a specific boost version that is newer, and does work, i can make a PR to their formula?

@axic Answered, and I'll update docs and issues accordingly when this is merged. |

I'm merging this to have some progress. Created an issue to track: ethereum/solidity#6349 |

Thank you @ChrisChinchilla for this PR! I wrote a guide here to share my steps how the downgrade process from 0.5.x to 0.4.x looks like. |
