Free Pascal 2.6.x + linker options

Hi,

I followed Andru's excellent instructions for setting up the cross
compiler with Free Pascal 2.6.x:

http://zengl.org/wiki/doku.php?id=compilation:android

Now everything seemed to work and I could compile the OpenGL projects
with VFPv2 floating point precision.

However, when I tried to recompile one of the Lazarus packages (e.g.
FCL), I would get this error:
Code: [Select]Target OS: Linux for ARMEL
Compiling fcllaz.pas
PPU Loading /usr/lib/fpc/2.6.1/units/arm-linux/rtl/system.ppu
Trying to use a unit which was compiled with a different FPU mode
Fatal: Can't find unit system used by fcllaz

So I though, maybe "-CfVFPv2" isn't passed to the linker.

After updating fpc.cfg, with the following lines
Code: [Select]#IFDEF CPUARM
  -dANDROID
  -CpARMv6
  -CfVFPv2
  -Xd
#ENDIF
everything works fine.

Is this what you're supposed to do? The linker options of the current
project are not passed to the required packages automatically?

put -CfVFPv2?

What Lazarus version are you using? My Lazarus 0.9.30.4 behaves the
same as yours, but my 1.1 detect compiler options change and attempt
to recompile package dependencies with it. Well if not (sometimes it
happens), just Run->Clean up build files->Clean and build.

Version 0.9.31. Sounds like I need to update it to a more recent
version then.
