Then you could try compiling your program with the switch
-Fl /usr/lib/arm-linux-gnueabihf

{Note its a lower case l not an upper case I (as per your grep!) after
the -F}

You MIGHT get a bit farther. However, the real problem though, as Jonas
explained, is you have an ARMEL compiler but an ARMHF system.

You need to download, or build yourself, an ARMHF compiler.
Please follow the links in Jonas's first post here.

Jonas pointed out to me when I went through this a couple of weeks ago 
that fpc.cfg isn't used while FPC is being built.

Another problem is, as I downloaded the wrong version and ran its
install.sh (as root), how can I uninstall it?

Thanks!

Hi Peter,

xrfang@pi ~ $ grep FI /etc/fpc.cfg
# nested #IFNDEF, #IFDEF, #ENDIF, #ELSE, #DEFINE, #UNDEF are allowed
# -d is the same as #DEFINE
#DEFINE NEEDCROSSBINUTILS

Thanks!

I asked on the list before.  The version shipped with Pi is 2.6.0, and is
said to be very buggy, I need version 2.6.4, so I downloaded from official
site.

The symbols the OP is missing are defined in crti.o
Without further information from him, its impossible to know whether the
problem is that
1) crti.o is not installed (its libc..dev not FPC)
2) The -Fl option does not use the right path for the system in use.

I would suggest the following;
try the command
ls /usr/lib/**/crti.o

If it works, use the given path for -Fl (as per the links already given
in this thread.
If it does not work, install the libc package that contains crti.o, and
repeat the test.

The version on the FPC website is an ARMEL version, so it will look for 
the ARMEL version of crti.o (in /usr/lib/arm-linux-gnueabi).

You don't get it from the Pi website, but by using the package manager 
of your linux distribution (apt).


The version from the FPC website is not appropriate for your Linux 
distribution, as it is for ARMEL and you have ARMHF.

Official from where: from your Raspberry Pi repository, or downloaded 
from our website? In the latter case: there are approximately a thousand 
different variants of ARM Linux (*), and your Raspberry Pi is using a 
different one than the one for which our FPC 2.6.4 was compiled. If you 
are using the one from your Raspberry Pi repository, it should work.


If you want more information, everything you may ever want to know about 
what could go wrong with compiling for Raspberry Pi has been discussed 
in http://lists.freepascal.org/fpc-pascal/2015-August/thread.html#44987


You can also try FPC 3.0 rc1 for Raspberry Pi, as mentioned in

To build FPC programs on linux one generally needs a variant of
libc-dev, which is not part of FPC itself.
The package you need might be libc6-dev, or some other combination of
'libc' and 'dev'.

Please post the solution if/when you find it for the benefit of others.
This same question seems to keep poping up on this list.
