macOS Catalina compatibility issues

[mparksUCO]

Hello,
I am having problems installing smc++ on my mac laptop and desktop, and it seems like there may be compatibility issues caused by the Catalina OS - particularly between gcc and Xcode. For example, here is an error message I get during the installation process:

---

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/execinfo.h:42:49: error: expected initializer before '__OSX_AVAILABLE_STARTING'

Are other users having similar issues, if so is there a simple way to get around this? Apologies if I am missing something obvious, but I have been following the installation instructions both for Anaconda and a local build/installation and am not having any luck getting things up and running.

Thanks in advance for any help you can offer, I am happy to provide any more information that might be helpful.

Thanks for reporting. I don't know anything about this error other than what I found on Google. It seems possibly related to Homebrew/homebrew-core#44579. From that, my best guess is that it's a compiler configuration issue. The software builds on my MacBook using gcc-8, so one recommendation might be to upgrade your compiler. In general, I have found that building software using the GCC toolchain has gotten progressively harder with each new OS X release.

Hi Jonathan,
thanks for the insight, that is helpful to know. I was actually able to get things running using a Docker container, which could be helpful for other folks with installation difficulties.

Thanks again!

Glad to hear that you got it working. When I created this program Docker was not such a thing, but releasing a Docker image might be the best option now. I will go ahead and close this issue.
