# To use this script you need
|
||
|
|
# - a Linux system >=2.4 with libc >=2.2.*
|
||
|
|
# - the valgrind debugger (http://www.valgrind.org/)
|
||
|
|
# - lots of memory (RAM + swap space > 600MB!) and
|
||
|
|
# - a fast computer =or= a lot of patience.
|
||
|
|
#
|
||
|
|
# It is useful (but not required) to compile FlightGear without
|
||
|
|
# any optimizations (-O0 without -funroll-loops etc.). Otherwise
|
||
|
|
# the debug messages might not seem to make sense in some cases.
|
||
|
|
#
|
||
|
|
# The sample suppression file is designed for a SuSE 7.1 system
|
||
|
|
# with Linux 2.4.18, XFree86 4.2.0 and a 3dfx card. Don't use it
|
||
|
|
# as it is, but create your own! You will likely have different
|
||
|
|
# libraries with different bugs.
|
||
|
|
#
|
||
|
|
# If you have problems with valgrind and FlightGear, don't bother
|
||
|
|
# the valgrind author -- ask on the flightgear-devel list first!
