Hello,

Yes, I've followed this wiki page to download binutils, build it and 
cross compilled fpc to get a ppcrossarm

http://wiki.lazarus.freepascal.org/Setup_Cross_Compile_For_ARM

I'm compiling the project with

/usr/bin/fpc  -MObjFPC -Scghi -CX -CirotR -O1 -TLinux -Parm -g -gl -XX 
-va -l -Filib/arm-linux/ 
-Fu/home/anton/development/lazarus/lcl/units/arm-linux/ 
-Fu/home/anton/development/lazarus/lcl/units/arm-linux/qt/ 
-Fu/home/anton/development/lazarus/packager/units/arm-linux/ -Fu. 
-FUlib/arm-linux/ -Xd -Fl/home/anton/new_lib -dLCL -dLCLqt 
/tmp/testcompileroptions.pas

Kind Regards
Anton
