[fpc-devel] Arm Thumb2 - Stellaris status

[David Welch]

Ahhhh! that makes sense.  I assume that is either leftover from a prior 
build?  And how do I get a new/fresh build to look in the right place?

If I remove the offending fpc/2.7.1 directory and rebuild. (without 
trying to change the prefix)  it puts the same stuff back in that directory:

/opt/embarm/arm-embedded-ld: warning: library search path 
"/usr/local/lib/fpc/2.7.1/units/arm-embedded/rtl/" is unsafe for 
cross-compilation

Am I doing this wrong?

make clean buildbase installbase CROSSINSTALL=1 OS_TARGET=embedded 
CPU_TARGET=arm

If I change it to this?

make clean buildbase installbase CROSSINSTALL=1 OS_TARGET=embedded 
CPU_TARGET=cortexm3

and provide the necessary cortexm3-embedded-* tools.

make: -iVSPTPSOTO: Command not found
make: -iSP: Command not found
make: -iTP: Command not found
make: -iSO: Command not found
make: -iTO: Command not found
Makefile:203: *** The Makefile doesn't support target cortexm3-embedded, 
please run fpcmake first.  Stop.

Thanks,
David
