Bootstrapping FPC for a new architecture
Without pre-compiled binaries
On the bootstrapping machine
1. Check out FPC from SVN:
$ svn co http://svn.freepascal.org/svn/fpc/trunk/
2. Install the gcc cross toolchain for the target architecture:
$ apt install gcc-m68k-linux-gnu g++-m68k-linux-gnu cpp-m68k-linux-gnu
4. Enter FPC source directory and build a cross-compiler:
$ BINUTILSPREFIX=m68k-linux-gnu- make crossall crossinstall CPU_TARGET=m68k CROSSOPT="-Cp68020 -Cf68881 -CaDEFAULT" OS_TARGET=linux FPC=/usr/lib/fpc/3.0.0/ppcx64 INSTALL_PREFIX=/home/glaubitz/fpc-m68k/
5. Build the native compiler:
$ BINUTILSPREFIX=m68k-linux-gnu- make compiler CPU_TARGET=m68k OS_TARGET=linux FPC=/root/fpc-m68k/lib/fpc/3.1.1/ppcross68k CROSSOPT="-Cp68020 -Cf68881 -CaDEFAULT -Fu/root/fpc-m68k/lib/fpc/3.1.1/units/*
Note: The options for CROSSOPT can be obtained by running "ppcross$CPU" after the initial build without parameters:
~/trunk# ./compiler/ppcross68k -ic 68000 68020 68040 68060 ISAA ISAA+ ISAB ISAC CFV4E ~/trunk# ./compiler/ppcross68k -if SOFT LIBGCC 68881 COLDFIRE ~/trunk# ./compiler/ppcross68k -ia DEFAULT ~/trunk#
6. Copy target compiler into directory of cross-compiler:
$ cp -av compiler/ppc68k /home/glaubitz/fpc-m68k/lib/fpc/3.1.1/
7. Tar the target compiler up to transport it to the target machine:
$ tar czf fpc-m68k.tgz /home/glaubitz/fpc-m68k
On the target machine
1. Check out FPC from SVN:
$ svn co http://svn.freepascal.org/svn/fpc/trunk/
2. Untar cross-compiled target compiler:
$ tar xf fpc-m68k.tgz
3. Build FPC with the bootstrapped FPC:
$ make FPC=/path/to/ppcbinary FPCDIR=/path/to/fpc/root OVERRIDEVERSIONCHECK=1 all
FPC usually being /usr/local/lib/fpc/x.y.z/ppc$CPU and FPCDIR /usr/local/lib/fpc/x.y.z/ when the tarball generated on the bootstrapping host was extracted into /usr/local.
Then skip to Creating the Debian package
With pre-compiled binaries
1. Download the binaries for your architecture from ftp://ftp.freepascal.org/pub/fpc/dist/ (chose the latest version, then your target).
$ wget --no-check-certificate https://downloads.sourceforge.net/project/freepascal/Linux/3.0.2/fpc-3.0.2.mipsel-linux.tar
2. Extract the tarball
$ tar xf fpc-3.0.2.mipsel-linux.tar
3. Run install.sh to install fpc into your home directory or /usr/local (the latter requires root privileges)
$ cd fpc-3.0.2.mipsel-linux $ ./install.sh

+.SH NAME
+ppcmipsel \- Free Pascal Compiler (FPC) binary, name derived
+from Portable Pascal Compiler
+
+.SH SYNOPSIS
+
+.B "ppcmipsel [options] [sourcefile]"
+.BR
+
+.SH DESCRIPTION
+This binary is the back-end binary of the
+.I Free Pascal Compiler (FPC)
+which is a
+.I Turbo Pascal
+and
+.I Delphi (7.0)
+compatible standalone (non GCC frontend) multitarget Pascal compiler.
+
+This binary should not be called directly, instead the
+.B fpc
+program should be used instead.
+It will choose the right back-end for compiling units for the requested platforms.
+
+.SH OPTIONS
+
+For a complete list of all supported command-line options, see the
+.BR fpc (1)
+manual page.
