I am attempting to configure Free Pascal 3.0 and Lazarus packages for

Here are the steps leading to the failure:
I am starting with a working copy of fpc 2.6.4 linux arm on my Raspberry Pi.
There are
a) the official FPC 2.6.4 for Linux ARM, which is for the ARMEL EABI
while the Raspberry Pi uses ARMHF EABI (it can run ARMEL EABI binaries
too, but you quickly get into trouble when you have to link against
libraries, unless you install ARMEL EABI versions of all libraries too)
b) the FPC 2.6.4 + Debian patches for the ARMHF EABI, which is broken
and which cannot be used to compile FPC 3.0.0 without disabling the
optimiser (otherwise you get a crash while compiling the system unit
with ppc1)
Which version of FPC 2.6.4 are you using?
I check out fpc branch fixes_3_0 from the free pascal subversion server
on my Raspberry Pi.
I change to the fpc folder (containing branch fixes_3_0)and type "make
all" on my Raspberry Pi.
I guess this means you are using the official FPC 2.6.4, otherwise you
wouldn't get as far as the errors below. In that case, you must add
OPT=-dFPC_ARMHF to your make invocation to compile FPC for the ARMHF EABI.
After about five minutes of build time, the make process stops with the
following output:
fpmake.pp(49) Warning: "crtend.o" not found, this will probably cause a
linking failure
fpmake.pp(49) Warning: "crtn.o" not found, this will probably cause a
linking failure
That's probably because the compiler is looking for the ARMEL EABI
versions of these files, which are most likely not installed on your
system. Make sure to install the "libc-dev" package to get the ARMHF
versions of these object files.
/usr/bin/ld: warning: link.res contains output sections; did you forget -T?
/home/pi/Development/Base/fpc/rtl/units/arm-linux/cprt0.o: In function
`_haltproc_eabi':
(.text+0x88): undefined reference to `_fini'
/home/pi/Development/Base/fpc/rtl/units/arm-linux/cprt0.o: In function
`_haltproc_eabi':
(.text+0x90): undefined reference to `_init'
That's as predicted by the warnings above.
