[mapserver-users] Is Mapserver known to play nice with Proj 6.3 ?

[Herzmann, Daryl E [AGRON]]

Greetings,

I'm attempting to use Mapserver with Proj 6.3 and am wondering if this combination is known to work?  I've been experiencing some issues.

1) For my deployment of FastCGI mapserver (master or 7.4.x build) and based on my monitoring, CPU usage is about double vs my previous setup of mapserver 7.3.x and Proj 5.2.0.  My comment here is lame I know as I have yet to produce a test case showing that actual difference.  All the other support libraries that went into the new build are updated too, so it is unfair to perhaps blame proj here :)  I had lots of previous fun[1] with a newer proj and postgis when an old sqlite3 library is at play, but I'm using the most recent version of that here.

2) I could not get master branch to build with proj 6.3, I get the error:

[  0%] Building C object CMakeFiles/mapserver.dir/fontcache.c.o
In file included from /home/akrherz/projects/mapserver/mapproject.h:46,
                 from /home/akrherz/projects/mapserver/mapshape.h:35,

 #error 'To use the proj_api.h you must define the macro ACCEPT_USE_OF_DEPRECATED_PROJ_API_H'

Which is described in this closed issue: https://github.com/mapserver/mapserver/issues/5766

Strangely, this builds just fine on the branch-7-4 branch without any code workarounds.

3) I've been seeing lots of segfaulting and coredumps

4) It appears like Travis CI testing is all against proj 6.1.1, maybe I should revert to that? :)

thanks
