Hi, I'm actually trying to compile the old version 0.6.1of Flight Gear on SuSE Linux 8.2. The compiler is gcc version 3.3 20030226."Configure" works fine, but with "make" the comiler produces the following error messages: linux:/usr/local/FlightGear-0.6.1 # makeMaking all in Includemake[1]: Entering directory `/usr/local/FlightGear-0.6.1/Include'make[1]: Nothing to be done for `all'.make[1]: Leaving directory `/usr/local/FlightGear-0.6.1/Include'Making all in Libmake[1]: Entering directory `/usr/local/FlightGear-0.6.1/Lib'Making all in Bucketmake[2]: Entering directory `/usr/local/FlightGear-0.6.1/Lib/Bucket'c++ -DHAVE_CONFIG_H -I. -I. -I../../Include -I../.. -I../../Lib -I/usr/local/include -I/usr/X11R6/include -g -O2 -c newbucket.cxxIn file included from ../../Lib/Misc/fgpath.hxx:34, from newbucket.cxx:33:../../Include/compiler.h:90:6: #error Time to upgrade.

Nevertheless it's important for me to compile exactly this version of FGFS on SuSE 8.2 (or higher). Does anyone have any idea to solve this problem? Many thanks in advance!

>Does anyone have any idea to solve this problem?Try to use an older compiler like gcc-2.7x, maybe that helps.
