postgis2 fails to compile on Mojave with Xcode 11.1

[EJFielding (Eric Fielding)]

I ran a port selfupdate and port upgrade outdated today, and the postgis2 2.5.3 version failed in the configure step.

The config.log file is long, so I will attach it.

It seems that it can't find usable GDAL headers. From the main.log:

XCode 11.1 only includes the MacOSX10.15.sdk, but port still wants to use 10.14. I worked around this by making a soft link so that configure scripts would work correctly. The other option is to revert to XCode 10.

$ cd /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs
$ sudo ln -s MacOSX.sdk MacOSX10.14.sdk

On a clean install of MacPorts-2.6.4_1-11-BigSur on macOS Big Sur 11.2.3, trying to install "postgis2" fails. XCode version is 12.4.

The "softlink" workaround suggested above by Wyllys Ingersoll doesn't work for me. Seeing exactly the same error as indicated by Eric Fielding.

Is there any reason why you'd prefer postgis2 to postgis3?

[EJFielding (Eric Fielding)]

I forget now why I had postgis2 installed more than a year ago when I reported it, but I uninstalled it and did not need it again.

[Veence (Vincent)]

I think the best way to address this ticket is by having postgis2 removed. Anyone would object to this?

[cbrown06 (Christopher Brown)]

@Veence - to answer your question, yes there is a reason, it's to align my development environment on macOS with the target Ubuntu 18.04 LTS server configuration, which (according to my sysadmin, who prefers to avoid installing external APT repositories), "postgis2" is available but not "postgis3".

Even if that would be ideal, I'm open-minded and have considered "postgis3"... except that failed for me in the same way: ​https://trac.macports.org/ticket/62114#comment:4

Seems like the "postgis3" port has exactly the same problem (I tried and can confirm this). I suppose that a fix for "postgis3" would be back-portable to "postgis2", but that's just a guess on my part. Even if the issue is resolved only for the "postgis3" port, that's OK for me (and thanks in advance, it's much appreciated if it can be done).
