This message contains a progress report, and some more questions:
Progress
======
Thanks to Vincent, using fpc as the compiler, and using this spell in
/etc/fpc.cfg (which will be added to the default fpc package)
echo '#include /usr/lib/fpc/2.3.1/fpc-cross.cfg' >> /etc/fpc.cfg
and then the file /usr/lib/fpc/2.3.1/fpc-cross.cfg can have 1 #include
per cross compiler e.g.
#include /usr/lib/fpc/2.3.1/fpc.powerpc-linux.cfg
these will be easy to add and remove with postinst and postrm for
package managers.
A typical file might be:
$ cat /usr/lib/fpc/2.3.1/fpc.powerpc-linux.cfg
# Detect powerpc-linux compiles
#IF $fpc-target = powerpc-linux
-XPpowerpc-linux-gnu-
#WRITE binutils prefix powerpc-linux-gnu-
#END
The actual -XP entry will depend on what the binutils prefix was when
the cross compile package was actually built.
THAT much works; so merely installing a cross-compiler deb will let
lazarus just pick it up and run....
Problems
======
However the next problems: rebuilding lazarus (lcl etc) is done by a
makefile, e.g.:
/usr/share/lazarus/lcl/ && /usr/bin/make clean all -w CPU_TARGET=powerpc
fpc is not called by the makefle, so /etc/fpc.cfg is not read, and of
course this needs adding:
BINUTILSPREFIX=powerpc-linux-gnu-
or whatever the prefix actually needs to be; but thats too long winded;
we already solved this problem by using fpc.
So... I guess I need to find out why /usr/bin/ppcrossppc is being used
directly and not fpc...
And why lazarus insists on making clean and making in /usr/share/lazarus
even though I'm not root and don't have write access, but that can come
later...
And then (finally, please let it be finally) where cprt21.o is or comes
from for powerpc. Maybe I missed it in the cross-deb?
