postgis - Building mapnik 3.0 in raspberry pi -

i have latest version of postgis (2.1.8) in raspberry pi. not use default mapnik version (2.0) available in raspberry pi packages because newer postgis not have functions old mapnik looks for.

so, tried compile latest version of mapnik (3.0) . configure successful finding required dependencies. when make, fails insufficient memory. increased swap 2gb. still fails insufficient memory.

i wondering if there way compile mapnik @ smaller steps not require memory @ once.

legacy postgis functions without st_ prefix can loaded on top of postgis database loading legacy.sql enabler script shipped postgis, in contrib share folder. run this:

psql -d [yourdatabase] -f legacy.sql 

find more on legacy.sql in chapter 2 of postgis manual.
