When running make bin/ivars-count, I get ... Error: execution of command failed with code: 1 ...

I tried running $ make bin/ivars-count and got the below error. What am I missing?

@drhuffman12 have you ever been able to build the compiler from source in that environment?

From the error seems more related to building the compiler directly rather than an issue in the repo.

[drhuffman12]

@bcardiff , I don't think I've tried building Crystal from source on this system. I'll try the link you sent. Thanks. 😄

[drhuffman12]

@bcardiff , I am using LLVM 10. I tried the steps in https://crystal-lang.org/install/from_sources/. Maybe I missed a step along the way? Do I need to revert to LLVM 8 noted in the doc's?

(a) Does the CRYSTAL_PATH env variable need to be set? I wasn't sure if CRYSTAL_PATH env variable does not contains ... was supposed to be warning or an error.

(b) So, I continued w/out setting it; and got the errors noted below. I then tried setting it to the path that it said it didn't contain (but should contain?); and I got the same error. (It kinda sounds like It passed std_spec but not compiler_spec as #9957. as noted in crystal-lang/crystal#6957 (comment), but I'm not sure the error is the same or not. Also, I think that issue is about Windows but I'm running on Linux Mint.)

(c) Also, I think there is a typo in CRYSTAL_PATH env variable does not contains .... I think the singular/plural forms of variable and contains should be in sync; or, change variable to variable(s) and contains to contain(s) and call it done. Is there an issue for this; I'm not finding one?

See below...

Working my way thru the steps noted in https://crystal-lang.org/install/from_sources/, when I got to the step make std_spec compiler_spec, it looks like std_spec finished successfully (trimmed for shortness):
