1. Get the lastest binutils sources, and build these with:
   
   
   • ./configure --target=arm-linux --disable-werror
   • make
   • sudo make install
   • sudo mkdir /opt/armbinutils
   • sudo ln -s /usr/local/bin/arm-linux-as /opt/armbinutils/as
   • sudo ln -s /usr/local/bin/arm-linux-ld /opt/armbinutils/ld
   • sudo mv /usr/local/bin/arm-linux-as /usr/local/bin/arm-linux-as_org
   • sudo nano /usr/local/bin/arm-linux-as
   • Put

     #!/bin/sh
     /usr/local/bin/arm-linux-as_org -meabi=5 -mcpu=cortex-a8 -mfpu=vfp3 -mfloat-abi=softfp $@          
                  

     in the editor and press CTRL+O for save, and CTRL+X for exit
   • sudo chmod 0755 /usr/local/bin/arm-linux-as
   
   
2. Put a repository, which contains a current FreePascal build, for your Debian-based Distribution in your /etc/apt/sources.list
   
   
3. Run: "apt-get install fpc subversion" (Subversion to checkout the FPC svn)
   
   
4. Go in the directory, where you want to checkout the FPC sources from the FPC svn
   
   
5. Run: "svn co http://svn.freepascal.org/svn/fpc/trunk fpc"
   
   
6. Create a directory for the .so Libs from your N900 device, and copy these from your N900 into this directory incl. symlinks as full "non-symlink!!!" copies
   
   
7. Create script "doit" in the from N900 "copied" lib directory with follow content:

   #!/bin/bash
   for FILE in *.so* ; do
     if [ -L "$FILE" ] ; then
       rm -f $FILE
     fi
   done
   for FILE in *.so* ; do
     G=`echo "${FILE}" | grep ".so."`
     if [ -n "${G}" ] ; then  
       A="${FILE%.so*}.so"
       if [ "${A}" != "{$FILE}" ] ; then
         if [ "${A}" != "{$FILE}.so" ] ; then
           ln -s $FILE $A
         fi
       fi
     fi
     G=`echo "${FILE}" | grep "-"`
     if [ -n "${G}" ] ; then  
       A="${FILE%-*}.so"
       if [ "${A}" != "{$FILE}" ] ; then
         if [ "${A}" != "{$FILE}.so" ] ; then
           ln -s $FILE $A
         fi
       fi
     fi
   done
   ln -s ld.so ld-linux.so.2 >/dev/null
           

8. Chmod 0755 the script and execute it in a terminal
9. Add follow text to /etc/fpc.cfg:

   #IFDEF CPUARM
   -Fu/usr/lib/fpc/2.5.1/units/$fpctarget/*
   -Fl/usr/lib/fpc/2.5.1/units/$fpctarget/rtl/
   
   -a
   -Sd
   -Xd
   -Xs
   
   -O-
   
   -CpARMV6
   -CfVFPV3
   
   -XP/opt/armbinutils/
   -Xr/usr/lib/fpc/2.5.1/units/arm-linux/rtl/
   -Xr/YOURDIRECTORYWITHTHEN900LIBS
   -XR/YOURDIRECTORYWITHTHEN900LIBS
   -darm
   -Tlinux
   #ENDIF       
           

10. Create a bash script file "doit" with follow context in the FPC trunk directory:

    #!/bin/sh
    sudo make clean
    sudo make crossinstall CPU_TARGET=arm OS_TARGET=linux CROSSBINDIR=/opt/armbinutils OPT=-dFPC_ARMEL INSTALL_PREFIX=/usr CROSSOPT="-CpARMV6 -CfVFPV3"
            

11. Set chmod 0755 for this script file and execute it in a terminal and wait :-)
    
    

Now use per project follow make script code:

#!/bin/sh
cp -s /YOURDIRECTORYWITHTHEN900LIBS/*.so* .
ppcarm -s -a -CpARMV6 -CfVFPV3 -Sd -B -dSDL -Xd -Xs -darm -Tlinux -TParm -O3 \
       -XP/opt/armbinutils/ -Xr/usr/lib/fpc/2.5.1/units/arm-linux/rtl/ -Xr/YOURDIRECTORYWITHTHEN900LIBS \
       -XR/YOURDIRECTORYWITHTHEN900LIBS -Fl/YOURDIRECTORYWITHTHEN900LIBS yourmainsourcefile.pas
./ppas.sh
rm -f ppas.sh
rm -f *.so*
    

Have fun with it! :-)
