Failed installation on MacOS due to missing CBC

[igoreulaers]

I have the same issue as has been described before in what seems to be a closed (ad perhaps solved?) issue: https://bit.ly/3BXa9Wj

When I try to install the package the link to CBC fails, although this has been installed successfully installed using Homebrew.

The specific console output of the failure is exactly the same as in the earlier closed issue: https://bit.ly/3BXa9Wj

Was there a solution to this issue?

Many thanks !

Hi @igoreulaers,

I've been playing around with installing rcbc on macOS using GitHub Actions, and the following instructions seem to work (see below). When you get a chance, could you please see if they work for you too?

Run these commands in the terminal to install CBC and dependencies:

brew tap coin-or-tools/coinor
brew install coin-or-tools/coinor/cbc
brew link cbc --force
brew link coinutils --force
brew link osi --force
brew link clp --force
brew link cgl --force

Run this command in R to install rcbc R package:

remotes::install_github("dirkschumacher/rcbc")

Hi @jeffreyhanson. It's still not working for me. I get the following error:

>  * brew: coin-or-tools/coinor/cbc (Mac OSX)

I'm on a macOS Ventura 13.3.1 Apple M2 Chip Pro R version 4.3.0 (2023-04-21).

I have successfully installed cbc in my machine using Homebrew.

I solved it by installing pkg-config separately using homebrew on my terminal

brew install pkg-config

And then running

remotes::install_github("dirkschumacher/rcbc")
