error: thread-local storage is unsupported for the current target

[kencu (Ken)]

only newer versions of clang support thread_local (800 or newer I think), but macports-clang-X should support it from about 3.5 onwards (not 100% certain of the floor) - certainly macports-clang-5.0+ supports it on macOS 10.7+ .

I'll check on that. I have it building now.

[kencu (Ken)]

blacklisting clang < 800 with compiler_blacklist_versions appears to do it. That forces mavericks to call in clang-4.0, which supports thread_local.

$ port -v installed uhd
The following ports are currently installed:
  uhd @3.11.0.0_0+docs+examples+gpsd+libusb+manpages+manual+python27+test (active) platform='darwin 13' archs='x86_64' date='2018-03-06T17:51:31-0800'

portconfigure.tcl should be updated at some point soon to fall back to clang-5.0 instead though, I think -- that's what the cxx11 1.1 portgroup calls in, so might as well be consistent.

[kencu (Ken)]

to the original poster: To get this to build right now, you could do this:

sudo port -v -N install clang-5.0

then

sudo port -v -N install uhd configure.compiler=macports-clang-5.0

and that should do it for you, until the Portfile is updated.

@kencu: Can you provide a patch (or do a PR)? Why recreate the wheel ;)

[kencu (Ken)]

This should do it -- works here, and looks clean to me...

[michaelld (Michael Dickens)]

In b10804aa96aac81373977be1b6d44fd5e879f0b2/macports-ports:

uhd*: require a compiler that supports thread_local storage

This requirement was introduced in 3.11.0.0.

Closes #55980

[michaelld (Michael Dickens)]

Thanks, @kencu,. I tweaked it a little for formatting and the comment. I went ahead and closed this ticket, but if this fix doesn't work for folks please reopen and explain what's going on. Please remember that you need to "sync" or "selfupdate" to get the changes, then it would be wisest to "clean" this port before trying again.,

Thanks! Seems to work.
