Error running on MacOS

[ankeshanand]

Hi,

I get this issue when trying to run on MacOS (High Sierra). Here's the stacktrace:

Traceback (most recent call last):

I am guessing the issue is with C++ libraries on MacOS, but I have been unable to debug.

What compiler is being used to build this and what version of the compiler? Also could you create a fresh checkout of the repo and re-run the build, then paste the entire log here, along with the traceback when you run pytest coinrun from the repo directory?

[christopherhesse]

Going to assume this is a one-time issue and close it until the original poster responds.

[ankeshanand]

Yeah, sorry you can close this for now. I haven't had a chance to build it on MacOS again.

[ankeshanand]

I tried this again and unfortunately the issue remains. Env details: Conda distributed Python 3.6.8, Mac OSX Mojave. I am pasting the relevant logs here:

A bunch of complier warnings follow and the error is:

And looks like the compiler is: GCC 4.2.1 Compatible Clang 4.0.1 (tags/RELEASE_401/final)] on darwin

[christopherhesse]

What's the output of gcc --version?

[ankeshanand]

gcc (GCC) 4.8.5

[christopherhesse]

What happens if you compile with clang instead of gcc?

[ankeshanand]

Compiling with clang made it work, thanks! :)
