Hi,
I am currently thinking about switching development from PIC-based
microcontrollers (based on mikroe compilers) to ARM Cortex-M3/4
controllers because they seem to be supported by fpc.
I have compiled latest binutils for arm based on instructions from the
wiki ( ./configure --target=arm-linux --prefix=/opt/embarm/
--program-prefix=arm-embedded- --disable-werror)
on my mac and then have checked out fpc-trunk ( svn co
http://svn.freepascal.org/svn/fpc/trunk fpc)
After starting up the compile (based on installed fpc-2.6.0) I end up
with those error messages:
make clean buildbase installbase CROSSINSTALL=1 OS_TARGET=embedded
CPU_TARGET=arm SUBARCH=armv7m

UniqueString seems to be an Ansistring function and on fpc-pacal I found
a post about a similar problem (Thread name is 'fpc 2.7.1 for
arm-embedded'), the solution there was to add:
{$ifdef FPC_HAS_FEATURE_ANSISTRINGS}
arround the code that breaks the build. I did this and now the cross
compiler compiles just fine
My question now is did I fix the problem correctly and if yes, could
someone please apply the patch to trunk?
Thank you,
Michael
