crypto/x509: macOS -framework Security produces link warning

[rsc]

See https://forums.developer.apple.com/thread/97850 for a bunch of people hitting a new link error in Xcode due to crypto/x509's use of the (apparently now deprecated?) -framework linker flag.

We could just take Merchant.Of.Satire's word for it, but it would be nice to have confirmation that we're not supposed to use -framework anymore, as opposed to some Xcode just being buggy/misconfigured/something else.

/cc @robpike who just hit this too.

This is what the full build looks like:

FYI: I get this also with Go 1.10.3 and the macOS 10.13.6 (17G65).

The -framework linker flag isn’t deprecated from what I can tell.

This is due to an out-of-sync Xcode/command line tools installation. You can try updating Xcode (if you’re running an outdated version) and then launch it to install the latest command-line tools.

If you already have the latest Xcode (or the above doesn’t solve your issue), you can re-install the command-line tools forcibly per http://sd.jtimothyking.com/2018/07/26/stub-file-and-library-file-out-of-sync/:

$ sudo mv /Library/Developer/CommandLineTools /Library/Developer/CommandLineTools.old
$ xcode-select --install
$ sudo rm -rf /Library/Developer/CommandLineTools.old

If this doesn’t work please re-open this bug and I’ll do more investigating.

Verified that those instructions resolved it for me.

This morning, I just upgraded the XCode and Command Line Tools (see the attached screen shot: sorry for Japanese), and then this problem appears again when I run all.bash for the tip version to rebuild everything.

While attempting to build my project (which relies on sqlite3) from macOS High Sierra (10.13.6), for use in a Linux Docker container, I set the environment variable CGO_ENABLED=0 and built the project. It turns out that this was not what I needed to do. Now (even after updating XCode & reinstalling XCode Command Line Tools) I get the warnings mentioned above.

Output from go build -v:
