The warnings look legit. I did a quick search and neither of those global variables are being used anywhere in the source (PNGsig is actually defined twice in 7.4, once in mapsymbol.c and again in mapogcsld.c). I assume that means they can be removed and/or the warnings can safely be ignored. Perhaps your compiler is just newer and therefore smarter?
Are you seeing issues beyond the warnings? --Steve -----Original Message----- From: mapserver-users [mailto:mapserver-users-boun...@lists.osgeo.org] On Behalf Of Flavio Hendry Sent: Tuesday, October 22, 2019 3:17 AM To: mapserver-users@lists.osgeo.org Subject: [mapserver-users] PIXMAP Symbols png and jpeg not recongnized Hi all Never had a problem with PIXMAP symbols, this is on a new install (tried to recompile several times and several versions, Ubuntu 18.04.3 LTS).
