kdelibs4 @ 4.14.3_15: build failure on Catalina

[DaveStrickland (Dave Strickland)]

Upgrading kdelibs4 failed on MacOS 10.15, including after cleaning the port and re-attempting. The normal build log is hard to interpret given the multiple things occurring in parallel, so I also tried with build.jobs=1 (which also failed) and have attached that log as well.

The single threaded log shows the error occurs when generating the tmo.h, tmo.cpp files associated with nepomuk, cannot find parser plugin for encoding trig:

same for me.

This also failed on the 10.15 buildbot, with the same issue. However, I just tried installing on a 10.15 VM, and it built successfully.

I checked the port for Soprano, which I believe (?) provides the parser plugin. But Soprano's portfile hasn't changed since 8/2020.

Nicolas, any ideas...?

For me the error is:

I think this error is not related and should be easy to fix, as it is because of the compiler not allowing comparison between integers and pointers. The attached patch should fix it, but do you get other errors after that? I did not experience that error, so I am wondering if you will encounter others. Also, if you do, please post the whole log (to try to see why you get these while I don't) and file a new ticket as the issue seems not related.

Patch for the pointer error

[kencu (Ken)]

I was going to take a look at this, but I can't get libiodbc to build at present ticket:62571

It'd be great if kdelibs4 could be configured to use a path-style dependency for libiodbc instead so it could use unixODBC as an alternative; there are other ports that depend strictly upon unixODBC, and since libiodbc and unixODBC conflict, it means one has to choose between KDE ports and those other ports...

[DaveStrickland (Dave Strickland)]

Thanks for mentioning libiodbc, that seems to be the key. I got soprano and kdelibs4 to compile successfully after getting libiodbc to compile successfully using the workaround in #51921.

Basically I did the following, although there might be a neater way of doing it.

sudo port uninstall libiodbc soprano
# Accepted when it warns that ports will break
sudo port clean libiodbc soprano
sudo port install -t libiodbc
# This command successfully builds and installs libiodbc, then recompiles kdelibs4 and various other kde applications

I'd be interested in hearing why this problem appeared in the first place, and what the trace mode does differently that gets around it, just for future reference.
