[mapserver-users] PHP_Mapscript swig issue on macOS.

[Paul Moen]

I am running into an error after trying Mapserver 7.4.1 on macOS 10.14 mojave with the php swig version of mapscript.

Here is the output from php -i when I am using php_mapscriptng.so

PHP Version => 7.3.8

mapscript

MapServer Version => MapServer version 7.4.1 OUTPUT=PNG OUTPUT=JPEG OUTPUT=KML SUPPORTS=PROJ SUPPORTS=AGG SUPPORTS=FREETYPE SUPPORTS=CAIRO SUPPORTS=ICONV SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER SUPPORTS=SOS_SERVER SUPPORTS=FASTCGI SUPPORTS=GEOS SUPPORTS=PBF INPUT=JPEG INPUT=POSTGIS INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE

I have a simple mapfile called test.map as follows.

		END
	END
END 

I create 3 pngs using 3 methods.

1. shp2img -m test.map > shp.png

For the next 2 I have enable_dl = On in my php.ini file so I can dynamically load the 
php_mapscript of my choice in the scripts.

2. To test php_mapscript, no swig, I use the following in a script called testOrig.php.
<?php
	dl('php_mapscript.so');
	$map= new mapObj('test.map');
	$name = "orig.png";
	$img = $map->draw();
	$img->saveImage($name);
?>
I call with the following,
php -f testOrig.php
It outputs the png file named orig.png

Both methods 1 and 2 output png files that are exactly the same.

3. To test php_mapscript via swig, I use the following in a script called testSwig.php.

<?php
	dl('php_mapscriptng.so');
	require('mapscript.php');
	$map= new mapObj('test.map');
	$name = "swig.png";
	$img = $map->draw();
	$img->save($name);	
?>
I call with the following,
php -f testSwig.php
It should output swig.png, but gives the following error.

msGetFontFace(): General error message. Freetype was unable to load font file "/Volumes/Data/WebServer/newswc/mapfiles/././Montserrat-Regular.ttf" for key "mon"
PHP Fatal error:  Uncaught Error: Call to a member function save() on null in /Volumes/Data/WebServer/newswc/mapfiles/testSwig.php:7

My fonts.list is a one liner, shown below with the font in the same directory as the mapfile.

mon	Montserrat-Regular.ttf

The map draws fine and the png is created if I take out the label.  The map will not work with any truetype font I have tried.  
How can I get more information regards to the freetype error that only happens with the swig version of mapscript?  

Thanks,
