Thanks Sven, that worked a treat. Now I need
to try to reproduce these crashes that are
plaguing Arm.

As a result I only have the AArch64
implementation of FPC installed. Is
there a way to cross-

install an
Arm version of FPC alongside my AArch64
version? I gather it's not quite
as simple as running i386 on x86_64.

You need to install arm-linux binutils
(don't know what the package is
called) and then you need to invoke make
like this:
make all CPU_TARGET=arm
BINUTILSPREFIX=arm-linux- FPMAKEOPT="-T
4" -j 4
Note 1: don't use "clean" and "all"
together with

parallel compilation
(the "-j 4")
Note 2: your prefix might be different,
e.g. arm-linux-gnueabi- or
something like that. Best try to execute
as/ld using tab completion in

the shell.
In theory it should also be possible to
run 32-bit ARM applications on

AArch64 though I have not tested that yet.
