That's great news - though we should all be frustrated, and curious, when things 'start' to work without our knowing why. We generally need to know 'why', so that we can re-apply the knowledge the next time we have a similar problem. But, of well. G...

Thanks for the reply Chris. I managed to get it working by doing a clean reinstall of Ubuntu WSL following https gist.github.com 4wk- 889b26043f519259ab60386ca13ba91b. Not quite sure what caused the issue but happy its working now.

I'm surprised that you're still seeing this problem. Have you downloaded and run the new installation script (from 16th March)? Does your system have newly installed usr local lib libc .1.0.dylib and usr local lib libunwind.1.dylib ?

Hello, after making my cnet install script executable, I was unable to run it. At first it said I did not have permission, but I followed the steps of the other help forum and solved it. Now it says curl not found. Please see attached

Wondering if anyone has experienced any problems installing or running cnet on Intel-based macOS? "No problems at all" is a valid response -) If you encountered a problem, and fixed it, what was the problem and its solution? Thank you,

ANONYMOUS wrote I'm try to understand and fix this problem; I'm confused why a (non-existent) library that my code is not dependent upon, is a show-stopper. Really hope to have a solution today.

How did you manage to solve this? Having the same issue on my M2 mac. libc .1.dylib doesn't exist on my machine.

Thanks Chris, that was the only other library needed. Cnet up and running

Hopefully this doesn't send you down a rabbit-hole, but try this https teaching.csse.uwa.edu.au units CITS3002 cnet downloads libunwind.1.dylib (I wish I knew why these libraries claim to be required - my code makes no reference to this (that's OK)...

ANONYMOUS wrote As we try to sort this out, please don't mix up topics - your comment, above, doesn't match this thread's Subject line. Not sure what you mean by 'compile-time issue'. Do you mean on my end, when building the pre-built binaries?


SVG not supported 4:47pm Sun 10th Mar, Christopher M.

I think that your macOS systems have Xcode installed (as required), but not the Command Line Tools. You can install them with xcode-select --install and then xcode-select -p should report their location.
