[MapServer-users] Swig Mapscript Still Fails to Build with PHP 8

[Jeff McKenna]

Hi BG,

Thanks for starting this discussion here, as many other readers will 
help & learn from your situation; I first want to wish you a warm 
welcome from the MapServer community :)

As Seth mentioned, I spent a lot of effort setting up the automated PHP 
8 + MapServer 8 builds "on the cloud", and some of those steps can be 
used by you directly.

But to step back a bit, first thing to mention is that PHP 8 with 
MapServer 8 is best handled through the SWIG library "master" branch, 
and this is likely one of your issues (the Homebrew formula you are 
using for SWIG is probably SWIG 4.0.x, and you need the upcoming 4.1.0 
release, or build its master branch from source).

Regarding the SWIG 4.1.0 upcoming release (and its heavy demand), see my 
call for help at 
https://lists.osgeo.org/pipermail/mapserver-dev/2022-September/016881.html

Regarding you possibly compiling SWIG 'master' branch, you can follow my 
exact steps to do this on these lines: 
https://github.com/MapServer/MapServer/blob/main/ci/travis/before_install.sh#L38-L47 
(maybe other Mac devs can update those steps here in this discussion 
thread for you)

I personally think all this will take some time before all packagers 
catch up to these changes, to make it smooth for their users.  In this 
case some time is required before the next SWIG can be released, and 
then propagated to all those FOSS4G packages that we love.

Its for this exact reason that I have put almost my entire career into 
MS4W, to prevent users from facing these same build challenges (and 
there are many challenges, ha).

I'm not sure that I've helped with this response, other than giving you 
some background info.

Don't be discouraged, you will indeed fall in love with MapServer :)

Thanks,

-jeff
