Description Gerald Pfeifer freebsd_committer freebsd_triage 2014-07-26 10:43:36 UTC 
We are working to change the default version of GCC from 4.7 (which
is end of life) to 4.8.

This port is one of a handfull that blocks this migration since it fails
to build on FreeBSD/amd64 10 as follows:

g++48 -DHAVE_CONFIG_H -I. -I..  -I../src/ -I../src/binreloc/ -I../src/enum/ -I../src/mas/ -I../src/mapgen/ -I../src/model/ -I../src/networking/ -I../src/pngfuncs/ -I../src/simulator/ -I../src/structure/ -I../src/tinyxml/ -I../src/tinyxpath/ -I../src/triangulation/ -DDATADIR=\"/usr/local/share\" -DSYSCONFDIR=\"/usr/local/etc\" -I/usr/X11R6/include  -DNDEBUG -Wall -Wmissing-braces -Wparentheses -pedantic-errors -I/usr/local/include/SDL -I/usr/local/include -D_GNU_SOURCE=1 -D_REENTRANT -D_THREAD_SAFE -I/usr/local/include/libpng15    -std=c++98 -O2 -pipe -Wl,-rpath=/usr/local/lib/gcc48 -fno-strict-aliasing -Wl,-rpath=/usr/local/lib/gcc48 -MT extensionmanager.o -MD -MP -MF .deps/extensionmanager.Tpo -c -o extensionmanager.o extensionmanager.cpp

Author: gerald
Date: Sun Aug 31 00:36:37 UTC 2014
New revision: 366693
URL: http://svnweb.freebsd.org/changeset/ports/366693

Log:
  Support building with modern, more standards-compliant compilers such
  as GCC 4.8.

  (For a project as little maintained upstream as OpenCity building with
  -pedantic-errors is a bad idea anyways.)

Comment 2 Gerald Pfeifer freebsd_committer freebsd_triage 2014-08-31 00:38:04 UTC 
This should be fixed now.
