Install FPC and Lazarus

Reference: http://wiki.lazarus.freepascal.org/Setup_Cross_Compile_For_ARM

But the binutils part should be omitted and instead use the binutils built by OE.

Use OE built binutils

Bake the binutils-cross-sdk:

 bitbake binutils-cross-sdk


Install the baked ipk, eg. binutils-cross-sdk_2.18-r13.1.6_i686-armv6-sdk.ipk, on the host:

 sudo dpkg --install --force-architecture binutils-cross-sdk_2.18-r13.1.6_i686-armv6-sdk.ipk


Create links to the binutils programs:

 cd ~/lazarus/fpc/binutils
 ln -s /usr/local/angstrom/arm/bin/arm-angstrom-linux-gnueabi-ld ld
 ln -s /usr/local/angstrom/arm/bin/arm-angstrom-linux-gnueabi-ar ar
 cat <<EOT > as
 #!/bin/sh
 /usr/local/angstrom/arm/bin/arm-angstrom-linux-gnueabi-as -meabi=5 \$@
 EOT
 chmod 755 as


Config fpc to use the binutils, edit ~/.fpc.cfg to include:

 #IFDEF CPUARM
 -XP/home/mike/lazarus/fpc/binutils/


Get target library files

Copy the target library files from OE to the host:

 cd /usr/local/angstrom/arm/arm-angstrom-linux-gnueabi
 sudo mkdir -p {lib/gcc,usr/lib}
 sudo rsync -av 192.168.0.24::oe/build/ok6410-tmp/sysroots/armv6-angstrom-linux-gnueabi/lib/* lib/
 sudo rsync -av 192.168.0.24::oe/build/ok6410-tmp/sysroots/armv6-angstrom-linux-gnueabi/usr/lib/* usr/lib/
 sudo rsync -av 192.168.0.24::oe/build/ok6410-tmp/sysroots/i686-linux/usr/armv6/lib/gcc/arm-angstrom-linux-gnueabi/4.3.3/* lib/gcc/


Config fpc to use the libraries, edit ~/.fpc.cfg to include:

 #IFDEF CPUARM
 -Fl/usr/local/angstrom/arm/arm-angstrom-linux-gnueabi/lib
 -Fl/usr/local/angstrom/arm/arm-angstrom-linux-gnueabi/usr/lib
 -Fl/usr/local/angstrom/arm/arm-angstrom-linux-gnueabi/lib/gcc
