mtxclient: error: no member named 'cerr' in namespace 'std'

[BobbyJackT]

I am installing Nheko with Mac Ports and when I get to the part when it is installing mtxclient it fails. I have included the log in the attachments.

In the future, please fill in the Port field with the port that actually fails to build and add the port maintainer(s) to Cc (port info --maintainers mtxclient), if any.

Your log file is garbled for some reason. The error appears to be:

Maintainer here. The thing about Nheko is that the origninal dev abandoned the project. Some others tried to revive it with "Nheko reborn", so this port will point to Nehko reborn. I'm just waiting to see how Nheko reborn shapes up. Worst case, I'll have this port switched to Nheko-reborn by the end November

Replying to mf2k:

Your log file is garbled for some reason.

Not garbled, the build system just inadvisedly decided to output ANSI color codes. Stripping those out, the error is:

Unless this port is finally getting updated in the near future…

In 230f24954c636a0fd2e8217657a69b45547d74c6/macports-ports (master):

mtxclient: update to version 0.3.1

• update mtxclient to version 0.3.1
• track nheko-reborn fork, as the original is no longer maintained
• set epoch to adjust for new versioning scheme
• add compiler blacklist for variant header

Closes: #59517
