ncurses @6.1 failing to build with non-default C++ stdlib

[letaage]

Trying to do a routine upgrade of ncurses,and it fails to build with error message "command execution failed"

Cleaned port and tried again, and still failed:

slim:~ tom$ sudo port clean --all ncurses

This error is preventing lots of other ports from being upgraded.

Your gawk is crashing. Pretty much the same issue as ProblemHotlist#ncurses6 (though I'm not quite sure how you got into this state since the ABI didn't change from 6.0 to 6.1). Workaround is to deactivate gawk while building ncurses.

Thanks for that suggestion, I am still having problems:

I searched for the gawk/dyld error you referenced in your reply and couldn't find it in the log file:

slim:webdl tom$ grep -in "dyld" /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_devel_ncurses/ncurses/main.log
slim:webdl tom$

Log file of ncurses build error, gawk deactivated

So you're using libc++ on 10.8. Seems to be missing a -stdlib argument when linking.

In cae5b7b72a400248b786f5d6288f7006f951f37d/macports-ports:

ncurses: restore explicit setting of CXXLIBS

See: #55801

[jmroot (Joshua Root)]

Has that change helped?

[letaage]

Yes, ncurses builds now. I still had gawk deactivated at the time, but it built.

Many thanks!
