Michael,
So build-jsc without the —jsc-only works:
lrowe at Laurences-MacBook-Air WebKit %
./WebKitBuild/Release/JavaScriptCore.framework/Helpers/jsc
>>> print(1+1)
2
I was hoping to try and wrap the jsc-only build into a rust crate since the
existing rust wrappers either include gtk dependencies or only wrap the
lower level api and link against the system libraries. Though it is looking
like I lack the C++ build experience to pull that off!
Thanks for you help debugging this. Is it worth turning this into a bug
report for fixing the jsc-only build on Mac?
