Meanwhile, msgsteiner requires OpenMP support. I found the solution to be as follows:\r\n\r\n1. Install the gcc compiler using homebrew: \r\n```brew install gcc```\r\nWhen installed, the compiler can be accessed via the `gcc-6` command.\r\n\r\n2. Building the Boost library using homebrew, specifying `gcc-6` as the compiler:\r\n```brew install boost --cc=gcc-6```\r\nWithout this extra argument, the library will not be visible to gcc when building msgsteiner.\r\n\r\n3. Similarly to the other patches, change the msgsteiner `Makefile` to use `gcc-6` instead of `gcc`.\r\n\r\nI wanted to contribute this piece of information since I spent a fair bit of time making sure msgsteiner could be built using Boost :)"}}
