   Ok, thanks. I now see that you need the hosts fpc to create the embedded version. I assumed only gcc was needed.

The given make-command only works as root, so i use a INSTALL_PREFIX:
    make clean buildbase installbase INSTALL_PREFIX=/home/sietse CROSSINSTALL=1 OS_TARGET=embedded CPU_TARGET=arm SUBARCH=armv7m
This works ok.

But the command
    fpc -Parm -Tembedded -Wplpc1768 -Cparmv7m tled1.pp
gives:
    Error: ppcarm can't be executed, error message: Failed to execute "ppcarm", error code: 127

I notice that "make installbase" did not install a program fpc in /home/sietse/bin, but I find
    /home/sietse/lib/fpc/2.7.1/ppcrossarm
If I try
    /home/sietse/lib/fpc/2.7.1/ppcrossarm -Parm -Tembedded -Wplpc1768 -Cparmv7m tled1.pp

So the ppcrosarm probably is the correct main program, but it seems that the fpc for the embedded port isn't installed.
Where is the fpc that will call ppcrosarm?

   Hopefully this make sense.
