Lots of warnings when running shen-ecl in OSX

[tizoc]

It seems to work fine in that it compiles and executes the code, but it keeps printing warnings constantly:

/private/var/folders/sy/4w247kq176z5n2k37nn3lblw0000gn/T/ecl062dRXZ8B.eclh:25:108: warning: shifting a negative signed value is undefined [-Wshift-negative-value]

It is always the same warning (because of ecl_make_fixnum), which seems to be coming from Clang. I'm not familiar with ECL, is it normal that it is generating and compiling C code while evaluating Shen code?

I am not able to reproduce with with ECL 16.1.3 built from source on Ubuntu 16.10. And I don't remember this happening on Windows.

I also didn't think bin/ecl/shen would generate C code on the fly while running.

On Ubuntu it does still show ;;; Loading #P"/usr/local/lib/ecl-16.1.3/cmp.fas" for 30 seconds when you start up bin/ecl/shen. I'm still trying to figure out how to fix that in another pull request: #6.

What version of Clang do you have? Is it bundled with ECL?

[tizoc]

ECL:

> ecl --version
ECL 16.1.3

Clang:

> clang --version
Apple LLVM version 8.0.0 (clang-800.0.42.1)
Target: x86_64-apple-darwin15.6.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

It is not bundled with ECL, it comes from Apple.

I'm trying to find if there is any way to specify the flags being passed to the C compiler, but I haven't found anything yet.
