Build error on macos x

[bentxt]

Hi
The following error after running jpm build

git clone https://github.com/janet-lang/jaylib
cd jaylib/
git submodule update --init --recursive
jpm build
compiling build/src___main.o...
cc1: error: argument to '-O' should be a non-negative integer, 'g', 's' or 'fast'
error: command exited with status 1
  in shell [/Users/ben/builds/bin/jpm] (tailcall) on line 264, column 5
  in do-rule [/Users/ben/builds/bin/jpm] on line 100, column 24
  in do-rule [/Users/ben/builds/bin/jpm] on line 98, column 44
  in do-rule [/Users/ben/builds/bin/jpm] (tailcall) on line 98, column 44

My system:

ProductName: Mac OS X
ProductVersion: 10.15.4
BuildVersion: 19E287

cc --version
cc (Homebrew GCC 9.3.0_1) 9.3.0

Can you please provide version of Janet? And I assume you are using homebrew to install it?

[bentxt]

No I used my self-built janet
janet -v
1.9.0-dev-dd458c8

but I unlink it and I'm switching to brew now

brew install janet
janet -v
1.9.1-meson

And again the latest from jaylib
git clone https://github.com/janet-lang/jaylib
git submodule update --init --recursive

Still the same

jpm build

compiling build/src___main.o...
cc1: error: argument to '-O' should be a non-negative integer, 'g', 's' or 'fast'
error: command exited with status 1
  in shell [/usr/local/bin/jpm] (tailcall) on line 128, column 5

Thank you. It seems like macos related thing.
