Hi,felix!Thank's for your help.I have downloaded and installed a standard gcc compiler which fits for my OSX(mountain lion 10.8.5).Then I set gcc as the default complier for my OSX.And now when my paparazzi firmware is building,What it shows at the beginning is:Using CC = /opt/local/bin/arm-none-eabi-gccUsing LD = /opt/local/bin/arm-none-eabi-gccUsing CP = /opt/local/bin/arm-none-eabi-objcopyUsing DMP = /opt/local/bin/arm-none-eabi-objdumpUsing NM = /opt/local/bin/arm-none-eabi-nmUsing SIZE = /opt/local/bin/arm-none-eabi-sizeGCC version:arm-none-eabi-gcc (GNU Tools for ARM Embedded Processors) 4.7.3 20121207 (release) [ARM/embedded-4_7-branch revision 194305]Is this OK for my paparazzi building?Another question,I want to know that the direction of the plane what is show on the screen of the GCS is determined by the magnetic compass.Or it is determined by the GPS?Since I fly lisa/m2 with float_dcm,which should not need the magnetic compass data to calculate the direction of the plane.I don't calibrate the magnetic compass.But I found that the direction of the plane doesn't point to the moving direction.Sometimes it even against the moving direction!Dose it relate to my plane crashing?And how could I fix it?Thanks a lot!!!
