Bootstrapping FPC for a new architecture
Without pre-compiled binaries
On the bootstrapping machine
1. Check out FPC from Git:
$ git https://gitlab.com/freepascal.org/fpc/source.git fpc-src
2. Install fpc and the gcc cross toolchain for the target architecture:
$ apt install fpc gcc-m68k-linux-gnu g++-m68k-linux-gnu cpp-m68k-linux-gnu
4. Enter FPC source directory and build a cross-compiler:
$ cd fpc-src ~/fpc-src $ BINUTILSPREFIX=m68k-linux-gnu- make crossall crossinstall CPU_TARGET=m68k CROSSOPT="-Cp68020 -Cf68881 -CaDEFAULT" OS_TARGET=linux FPC=/usr/lib/x86_64-linux-gnu/fpc/3.2.2/ppcx64 INSTALL_PREFIX=/home/glaubitz/fpc-m68k/
5. Build the native compiler:
~/fpc-src $ BINUTILSPREFIX=m68k-linux-gnu- make compiler CPU_TARGET=m68k OS_TARGET=linux FPC=/home/glaubitz/fpc-m68k/lib/fpc/3.3.1/ppcross68k CROSSOPT="-Cp68020 -Cf68881 -CaDEFAULT -Fu/home/fpc-m68k/lib/fpc/3.3.1//units/*"
Note: The options for CROSSOPT can be obtained by running "ppcross$CPU" after the initial build without parameters:
~/fpc-src $ ./compiler/ppcross68k -ic 68000 68020 68040 68060 ISAA ISAA+ ISAB ISAC CFV4E ~/fpc-src $ ./compiler/ppcross68k -if SOFT LIBGCC 68881 COLDFIRE ~/fpc-src $ ./compiler/ppcross68k -ia DEFAULT ~/fpc-src $
6. Copy target compiler into directory of cross-compiler:
~/fpc-src $ cp -av compiler/ppc68k /home/glaubitz/fpc-m68k/lib/fpc/3.3.1/
7. Tar the target compiler up to transport it to the target machine:
~/fpc-src $ cd $ tar czf fpc-m68k.tgz /home/glaubitz/fpc-m68k
On the target machine
1. Check out FPC from Git:
$ git https://gitlab.com/freepascal.org/fpc/source.git fpc-src
2. Untar cross-compiled target compiler:
$ tar xf fpc-m68k.tgz
3. Build FPC with the bootstrapped FPC:
$ make FPC=/home/glaubitz/fpc-m68k/lib/fpc/3.3.1/ppcm68k FPCDIR=/home/glaubitz/fpc-m68k/lib/fpc/3.3.1/ OVERRIDEVERSIONCHECK=1 all
4. Install the newly built FPC:
$ make FPC=/home/glaubitz/fpc-m68k/lib/fpc/3.3.1/ppcm68k FPCDIR=/home/glaubitz/fpc-m68k/lib/fpc/3.3.1/ OVERRIDEVERSIONCHECK=1 install INSTALL_PREFIX=/home/glaubitz/fpc CPU_TARGET=m68k
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

+.TH ppcmipsel 1 "30 may 1999" "Free Pascal" "Free Pascal Compiler"
+.SH NAME
+ppcmipsel \- Free Pascal Compiler (FPC) binary, name derived
+from Portable Pascal Compiler
+
+.SH SYNOPSIS
+
+.B "ppcmipsel [options] [sourcefile]"

+
+.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.
