Build Latest release License: APL 1.1 Issues Last commit

A maintained continuation of Directory Opus 5 Magellan II for AmigaOS 3, AmigaOS 4, MorphOS, and AROS, building on the 2012 APL source release with GCC / cross-toolchain support, modern platform fixes, and ongoing module work.

Looking for the original 2012 APL release notes? See README.legacy. The project was historically known as dopus5allamigas; the repository and project name are now just dopus5.

The 68000 OS3 variant ships in its own archive (DOpus5_<rev>_os3-68000.lha) so users on stock 68000-based hardware (A500, A600, A1000, A2000, CDTV) can run DOpus5 without needing the 020+ build. A1200 / A3000 / A4000 owners should use the regular os3 archive, which targets -m68020-60 -mtune=68030.

Pre-built binaries for every supported platform are published under Releases. Each tagged release ships one DOpus5_<rev>_<platform>.lha per target.

The project builds with GCC-based cross-compilation toolchains. The recommended way is via the prebuilt Docker images used by CI:

Native builds on Amiga / MorphOS / AROS are also possible if you have a working GCC + libc + AmigaOS SDK installed.

From inside the toolchain environment:

cd source
make os3 # AmigaOS 3 (default: -m68020-60 -mtune=68030)
make os3-68000 # AmigaOS 3, plain 68000 (-m68000)
make os4 # AmigaOS 4 (PPC)
make mos # MorphOS (PPC)
make i386-aros # AROS i386 (ABIv0)
make x86_64-aros # AROS x86_64 (ABIv11)

By default the build is a debug build. Add debug=no for the optimised release build:

make os3 debug=no

Building the .lha archive uses the same makefile:

cd source
make os3 release debug=no

The release archive ends up under releases/ as DOpus5_<rev>_<platform>.lha (or ..._dev_<platform>.lha for the debug variant).

The FTP module supports SFTP via libssh2.

• On AmigaOS 3 / AmigaOS 4 / MorphOS SFTP is always built in: the cross-build helper at source/Modules/ftp/third_party/libssh2/ fetches and statically links libssh2 1.11.1 by default.

• On AROS SFTP is opt-in (the AROS toolchain image already provides a shared libssh2):

  cd source
  make i386-aros sftp=yes
  make x86_64-aros sftp=yes

xadopus.module (archive-as-folder support via xadmaster.library) is built by default for every target. The CI Docker images ship the required proto/xadmaster.h headers.

If the headers aren't installed in a local/native build, it fails with fatal error: proto/xadmaster.h: No such file or directory, which is the expected outcome; install xadmaster's developer headers.

Consult source/makefile, source/makefile.common and the per-platform / per-module makefiles for the full list of targets and options.

The FTP parser / protocol / TLS tests run on a normal Unix-like host:

make -C source/Modules/ftp -f makefile.tests test

If libssh2 development headers are installed, the SFTP backend tests can also be run:

make -C source/Modules/ftp -f makefile.tests test-libssh2

CI runs both of these before kicking off the platform release builds.

Directory Opus 5 is released under the AROS Public License (APL) version 1.1 — see COPYING.

Optional builds may include or link third-party components. In particular, the FTP module's SFTP support uses libssh2 and zlib; see THIRD_PARTY_NOTICES.md for the relevant license texts.
