qgis3 @3.14.0_1: No rule to make target `.../resources/function_help/json/$$area'

[gwright83]

The most recent version of qgis3, qgis3@3.14.0_1 fails to build on macOS 10.14.6. The problem persists even if the previous version is uninstalled. I built the port with

sudo port install qgis3 build.jobs=1

to avoid previously noted parallel build problems.

The error at the end of the log:

The proximate error seems to be the lack of a rule to build src/src/core/qgsexpression_texts.cpp.

It may be relevant that I had done a port reclaim before trying to upgrade from qgis@3.14.0_0 to qgis@3.14.0_1. The upgrade failed. I uninstalled the old version of the port and tried to reinstall the new version. This also failed. Running port clean and then trying to install failed consistently three times with the same error message.

A complete log is attached.

Yeah, I differed because I hoped the new 3.14.1 version would solve that issue, but alas, no. I’m going to forward that error upstream and see if we can come with a quick fix (if that fix isn't already published)

More information:

I misread the original error message. The error is

:info:build make[2]: *** No rule to make target `/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_gis_qgis3/qgis3/work/QGIS-3_14_0/resources/function_help/json/$$area', needed by `src/core/qgsexpression_texts.cpp'.  Stop.

The problem is not that there is no rule to make src/core/qgsexpression_texts.cpp (as I originally said) but that there is no rule to make qgis3/QGIS-3_14_0/resources/function_help/json/$$area.

The file qgis3/QGIS-3_14_0/resources/function_help/json/area exists and seems to have reasonable content. It look like there are spurious dollar signs (perhaps from cmake?) that are confusing make.

[Veence (Vincent)]

A further problem is that the file src/core/qgsexpression_texts.cpp does not exist. I suppose generating this .cpp file entails building the $$area file somehow. The expression parser seems to rely heavily on flex.

[Veence (Vincent)]

Ok, I have a build:

Air > port installed | grep qgis3
  qgis3 @3.14.1_0+grass+postgresql12+python38 (active)

The fix is very simple. I will commit a patch tomorrow, and simultaneously report the issue upstream. Stay tuned.
