cat $HOME/.bin/zxx

Expected Behavior

compile successfully

Actual Behavior

error

    echo 'ZIG_LOCAL_CACHE_DIR="$HOME/tmp" zig cc -target '${libc}' $@' >> "$HOME/.bin/zcc"
    echo 'ZIG_LOCAL_CACHE_DIR="$HOME/tmp" zig c++ '${libc}' $@' >> "$HOME/.bin/zxx"

the single quotes are likely destroying the variable text replacement

These should be hard errors instead of warnings:

warning(link): framework not found for '-framework CoreFoundation'
warning(link): framework not found for '-framework Security'

In master branch, they are.

Looks like a duplicate of #1349.

@kubkon do we have a FAQ link or documentation page to link people to when they run into this particular issue?

Correct, I've fixed it for the next release from warnings into hard errors, but you know this already.

Looks like a duplicate of #1349.

Excellent question, and I don't think we have, no. Where would you think we should add info like this? Main docs? Or perhaps we should have a separate page for the toolchain (compiler+linker)?

[andrewrk]

I'd start with making sure #1349 has up-to-date info. Maybe an entry in https://github.com/ziglang/zig/wiki/FAQ that we can link to. And that's enough for now.
