This looks to be the error:

That was the error I saw on the ci system with clang 703.0.31 as well. When I blacklisted clang 703.0.31 all the ci systems built it <​https://travis-ci.org/macports/macports-ports/builds/476691407>, and it built for me with clang-5.0 as well.

But some version of Xcode that you have is failing. You can probably force it for right now with

sudo port clean gdb
sudo port -v install gdb configure.compiler=macports-clang-5.0

But to fix it for everyone, what version of Xcode clang do you have on that failing system?

$ clang --version
clang version 7.0.1 (tags/RELEASE_701/final)
Target: x86_64-apple-darwin10.8.0
Thread model: posix
InstalledDir: /opt/local/libexec/llvm-7.0/bin

I can't seem to find it in the log. Perhaps we need to be more blanket with our blacklisting.

It failed on 10.10 and 10.11:

• ​https://build.macports.org/builders/ports-10.10_x86_64-builder/builds/77193
• ​https://build.macports.org/builders/ports-10.11_x86_64-builder/builds/76672

[kencu (Ken)]

OK. We'll blacklist clangs less than 800.0.42.1 then. That should force them all up to clang-5.0, which works.

Thanks.

[jmroot (Joshua Root)]

It worked fine on 10.9, so that's not necessary. XcodeVersionInfo lists clang versions.

[kencu (Ken)]

10.9 built it with clang-5.0 as well, I note <​https://build.macports.org/builders/ports-10.9_x86_64-builder/builds/79025/steps/install-port/logs/stdio>.

In 612f1a8d5be2d52c98f42dfa7ec8f63f4d63bc7c/macports-ports (master):

gdb: blacklist clang < 801
