sorry, the command invoked was

 sudo port selfupdate

[kencu (Ken)]

Force clang 5.0 and you should be good. Thought we already did that...

[mrkapqa]

sorry, but i am still not up-to-date with the commands

​https://trac.macports.org/wiki/UsingTheRightCompiler

what should i do then?

sudo port install macports-gcc-5

and then

sudo port upgrade outdated

?

on a fresh installation of macports there appears also a build-error on gnutls

also after activating clang-5.0?

sudo port install clang-5.0 sudo port install mpv

Error: Failed to build gnutls: command execution failed

[kencu (Ken)]

gnutls is using a new symbol, ___get_cpuid_count that exists only in gcc and very new versions of clang. clang-7.0 and newer appear to have it.

On this 10.7.5 machine I have with me, the current portfile forces clang-8.0, and that works.

The defaulting on 10.6.8 might be different. Please make sure your portfiles are up to date, and then clean and try your install again:

sudo port selfupdate
sudo port clean gnutls
sudo port -v install gnutls

if it fails, then the blacklisting and fallbacks are wrong. In that case, force clang-8.0 yourself like this:

sudo port clean gnutls
sudo port -v -N install clang-8.0
sudo port -v install gnutls configure.compiler=macports-clang-8.0

and that should work. Report back success or failure.

Aside:

It might be simpler to just add a replacement for ___get_cpuid_count, I think. See <​https://reviews.llvm.org/D61036> and <​https://github.com/gcc-mirror/gcc/blob/master/gcc/config/i386/cpuid.h>.

Replying to kencu:

try your install again:

sudo port selfupdate
sudo port clean gnutls
sudo port -v install gnutls

if it fails, then the blacklisting and fallbacks are wrong. In that case, force clang-8.0 yourself like this:

sudo port clean gnutls
sudo port -v -N install clang-8.0
sudo port -v install gnutls configure.compiler=macports-clang-8.0

and that should work. Report back success or failure.

That helped very much, Gnutls is now installing thanks to

sudo port -v install gnutls configure.compiler=macports-clang-8.0

Build of mpv still fails, also when used with "configure.compiler=macports-clang-8.0; if i may i can add the log here.

Thank you very much.

[mrkapqa]

the error for mpv is

Command failed: cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_multimedia_mpv/mpv/work/mpv-0.29.1" && /opt/local/bin/python2.7 ./waf build -v Exit code: 1 Error: Failed to build mpv: command execution failed
