[Lazarus] Need suggestion about crosscompile on osx

You have to make all cross compile targets using fpc 2.6.4 as your working
compiler, and fpc 3.x as your source code compiler.

First you build a fpc 3.x compiler. Assuming you want to install off your
home folder somewhere, build fpc.3.x and cross compilers on osx like so:

# wherever you put the fpc.x source code
# i recommend somewhere under your home folder

# make and install the default fpc.3.x compiler
make all
# make the cross compilers
make crossinstall OS_TARGET=osx CPU_TARGET=x86_64 INSTALL_PREFIX=$BASE
make crossinstall OS_TARGET=linux CPU_TARGET=x86_64 INSTALL_PREFIX=$BASE
make crossinstall OS_TARGET=linux CPU_TARGET=i386 INSTALL_PREFIX=$BASE
make crossinstall OS_TARGET=win32 CPU_TARGET=i386 INSTALL_PREFIX=$BASE
make crossinstall OS_TARGET=win64 CPU_TARGET=x86_64 INSTALL_PREFIX=$BASE

# copy the compilers to the bin folder
cp $BASE/lib/fpc/$FPC_BUILD/* $BASE/bin

# make changes to your path
export PPC_CONFIG_PATH=$BASE/fpc/bin

# create a new fpc.cfg in the compiler folder
$PPC_CONFIG_PATH/fpcmkcfg -d basepath=$BASE/lib/fpc/\$FPCVERSION -o

# test the compiler path and configuration
cd $HOME
fpc -iv

You should see 3.0.1 if using svn fixes_3_0 branch.

Next you need to find the cross compiler tools and place them in the fpc
bin folder which is:


They are named like fpc.3.x/bin/i386-linux-as or
fpc.3.x/bin/x86_64-linux-ld. You need about 30 of these tools for all
platforms in total.

After that then you need to find the cross compiler libs, and place them in:

These are files like fpc.3.x/lib/x86_64-linux/libcairo.so or
fpc.3.x/lib/i386-win32/user32.dll. There's probably 200 or so of these
files you'll need.

I can't tell you where to get these files, but if you're desperate you can
pull them out of my bundle.
