Compiling MegaZeux

Compiling any MegaZeux 2.80 or later source requires a POSIX compatible shell (bash, dash) to be installed. Download the source .tar.bz2 or .tar.xz and extract it to a new folder.

General Commands

./config.sh

This will give you help about how to configure MegaZeux.

./config.sh --platform unix

To configure the sources. On OS X, the platform is "darwin", and on Windows the platform is either "win64" or "win32".

make

This will build MegaZeux from sources. If it fails, you probably don't have one of SDL, libvorbis, libogg, libpng, zlib or the corresponding dev packages installed.

make install

This will install MegaZeux to the system. This should not be used with the "unix-devel" platform or any other option intended to run straight out of the source directory.

Please see debian/README for more information.

Windows

For developing and testing MegaZeux with Windows, the generally supported POSIX platform is MSYS2. Other available options include MINGW32/msys, Cygwin, etc., but are typically more complicated than MSYS2. Download and install MSYS2 before continuing. MSYS2 no longer works on 32-bit Windows and recommends the UCRT64 environment, so that will be used here.

It is no longer recommended to produce release builds with MSYS2, as they have increased the default architecture of MINGW32 to pentium4 and the default architecture of MINGW64 to nocona. MegaZeux still targets i686 and x86-64 respectively. While most dependencies can be rebuilt, MSYS2 may or may not embed system library stubs that require the newer architectures into the binary (untested). Linux Mingw-w64 cross compilers are now recommended for release builds instead.

Windows with MSYS2

Run ucrt64.exe in the msys2 directory. You will be in the "{MSYS DIRECTORY}\home\{your username}\" directory. (This will display in the mingw64 shell as either "~" or "/home/{your username}")

First, run this command. MSYS2 will need to restart when it is finished.

yes Y | pacman -Syu

After restarting MSYS2, run the following commands.

yes Y | pacman -Su
yes Y | pacman -S git
yes Y | pacman -S make
yes Y | pacman -S mingw-w64-ucrt-x86_64-gcc
yes Y | pacman -S mingw-w64-ucrt-x86_64-gdb
yes Y | pacman -S mingw-w64-ucrt-x86_64-pkgconf
yes Y | pacman -S mingw-w64-ucrt-x86_64-zlib
yes Y | pacman -S mingw-w64-ucrt-x86_64-libpng
yes Y | pacman -S mingw-w64-ucrt-x86_64-libogg
yes Y | pacman -S mingw-w64-ucrt-x86_64-libvorbis
yes Y | pacman -S mingw-w64-ucrt-x86_64-SDL2
git clone https://github.com/AliceLR/megazeux.git
cd megazeux
./config.sh --platform win64
make

MegaZeux should be built and ready to run! If you are not running MegaZeux from ucrt64.exe, add the folder containing your dependencies (generally C:\msys64\ucrt64\bin) to your Windows PATH variable. Otherwise, MegaZeux will not be able to start from Explorer.

The following optional packages may be of use. They are not required or are part of the packaging process for some architectures.

yes Y | pacman -S autoconf
yes Y | pacman -S automake
yes Y | pacman -S libtool
yes Y | pacman -S nano
yes Y | pacman -S p7zip
yes Y | pacman -S mingw-w64-ucrt-x86_64-clang
yes Y | pacman -S mingw-w64-ucrt-x86_64-cmake
yes Y | pacman -S mingw-w64-ucrt-x86_64-diffutils
yes Y | pacman -S mingw-w64-ucrt-x86_64-imagemagick
yes Y | pacman -S mingw-w64-ucrt-x86_64-ntldd

Troubleshooting

- "The program can't start because ___.dll is missing."

If you are running MegaZeux from Explorer, add the folder containing your dependencies (generally C:\msys64\ucrt64\bin) to your Windows PATH variable.

- "The procedure entry point inflateReset2 could not be located in the dynamic link library zlib1.dll." (and similar errors)

This can happen because the Windows PATH variable contains a directory older copy of zlib1.dll (or the DLL in question). You can use where zlib1.dll in Command Prompt to view the different PATH locations that contain the DLL, as well as the order in which Windows will try to load it.

Ubuntu/Debian

sudo apt install build-essential

Download compilers to build MegaZeux. MegaZeux will also build with clang.

supo apt install libpng-dev libogg-dev libvorbis-dev libsdl2-dev

Download the dependencies required to build MegaZeux. To build with SDL 1.2, install the package libsdl1.2-dev.

To install the latest master, use:

sudo apt install git
git clone https://github.com/AliceLR/megazeux.git [dest dir]

Alternatively, download and extract the latest .tar.xz or .tar.bz2 source archive to the desired location.

See the "general commands" section above for more information.

Packaging

sudo apt install devscripts debhelper

Download the packaging tools.

From the MegaZeux source directory:

debuild -us -uc

Fedora

sudo dnf install gcc gcc-c++ make binutils

Download compilers to build MegaZeux. MegaZeux will also build with clang/clang++.

supo dnf install zlib-devel libpng-devel libogg-devel libvorbis-devel SDL2-devel

Download the dependencies required to build MegaZeux. To build with SDL 1.2, install the package sdl12-compat-devel (SDL-devel for older Fedora releases).

To install the latest master, use:

sudo dnf install git
git clone https://github.com/AliceLR/megazeux.git [dest dir]

Alternatively, download and extract the latest .tar.xz or .tar.bz2 source archive to the desired location.

Packaging

The rpm-build package is required:

sudo dnf install rpm-build

If you're building from a cloned Git repository, checkout the appropriate MegaZeux version tag. For example:

git checkout v2.93

To build the rpm:

make distclean
rpm-build -bb --build-in-place megazeux.spec

Mac OS X

With MacPorts (testing only)

You will need to install XCode and MacPorts before continuing. This method is suitable only for testing builds, and should not be used to produce releases.

Compile/install dependencies.

sudo port install zlib libpng libogg libvorbis libsdl

Navigate to the extracted source directory. If you're building MZX 2.90 and under, please download this updated Makefile.in and put it in arch/darwin/, otherwise MegaZeux will fail to compile.

Run ./config.sh with some or all of the following flags:

--platform darwin-devel   ---------- Mandatory.
--prefix /opt/local       ---------- Mandatory.
--disable-libsdl2         ---------- Use this if building against SDL 1.2 (optional).
--disable-utils           ---------- This disables compilation of utilities such as downver and checkres (optional).
--enable-release          ---------- Enables optimizations, resulting in a faster executable.

Build MegaZeux as usual:

make -j8

Multiarchitecture .app

THIS SECTION IS A WORK IN PROGRESS. Please refer to the documentation in arch/darwin/ and docs/platform_matrix.html for more details.

Environment Setup

This is heavily dependent on the architectures being targeted. For compilation on a Mac, typically select the highest Xcode being targeted as a base and install the lower versions using XcodeLegacy. Linux cross compilation isn't tested currently.

Architecture	MegaZeux PREFIX	SDK version	OS minimum version	Xcode toolchain	Cross toolchain	Notes
arm64	PREFIX_ARM64	11.0	11.0	Xcode 12.2 or higher	osxcross	Untested.
arm64e	PREFIX_ARM64E	FIXME	FIXME	FIXME	osxcross	Untested.
i686	PREFIX_I686	10.13	10.6	Xcode 9.4.1	osxcross	Mac OS X Snow Leopard is targeted to support Core Duo Macs.
x86_64	PREFIX_AMD64	10.13	10.6	Xcode 9.4.1	osxcross
x86_64h	PREFIX_AMD64H	10.13	10.9	Xcode 9.4.1	osxcross	OS X Mavericks is the minimum version for this architecture.
ppc	PREFIX_PPC	10.4	10.4	Xcode 3.2.6	osxcross (ppc-test)	Mac OS X Tiger is targeted to support G3 Macs.
ppc64	PREFIX_PPC64	10.5	10.5	Xcode 3.2.6	osxcross (ppc-test)	Mac OS X Leopard is targeted as Objective-C is broken for PowerPC64 in the Tiger SDK.

WARNING: if targeting PowerPC64 via XcodeLegacy, you need to revert a fix that XcodeLegacy applies to libgcc_s.10.5.dylib.

cp /Developer/SDKs/MacOSX10.5.sdk/usr/lib/libgcc_s.10.5.dylib /Developer/SDKs/MacOSX10.5.sdk/usr/lib/libgcc_s.10.5.dylib.vectorfix
cp /Developer/SDKs/MacOSX10.5.sdk/usr/lib/libgcc_s.10.5.dylib.bak /Developer/SDKs/MacOSX10.5.sdk/usr/lib/libgcc_s.10.5.dylib

Other required tools

dylibbundler, which can be installed using MacPorts:

sudo port install dylibbundler

WARNING: dylibbundler relies on otool and therefore llvm-objdump. LLVM currently lacks support for reading the LC_UNIXTHREAD load commands of PowerPC64 Mach-O executables, so bundling will fail. You may need to have a pre-LLVM Xcode selected to complete a PowerPC64 build.

Dependencies

FIXME!

Compilation

Unlike most other architectures, the prefix is provided PER ARCHITECTURE to a Makefile meta target.

./config.sh --platform darwin-dist --enable-release --enable-lto

To compile for a given architecture, provide to Make one or more of the PREFIX variables defined in the table above:

make PREFIX_I686=~/megazeux-dependencies/macos/i686 PREFIX_AMD64=~/megazeux-dependencies/macos/x86_64

For each architecture, Make will invoke:

make ARCH=[arch] PREFIX=[prefix] package
make ARCH=[arch] PREFIX=[prefix] clean

The "package" target is similar to "all", except afterward, dylibbundler is used to generate a dependency bundle in "bundles/", and then all binaries are moved to [binary].[arch].

Finally, Make will perform

make lipo

to merge all of the currently existing [binary].[arch] files into a new multiarchitecture file [binary].

Packaging

Make sure there is not a "MegaZeux" volume mounted before continuing.

rm -r build/
make archive

You can test the .app files generated in build/darwin-dist/ to make sure they run. A .dmg will appear in build/dist/darwin-dist/ containing the generated .app files, documentation, and multiarchitecture utilities.

HTML5 (Emscripten)

NOTE: emsdk may not function properly in MSYS2. Using Linux or similar is strongly recommended.

Download and install emsdk.

git clone https://github.com/emscripten-core/emsdk /opt/emsdk
cd /opt/emsdk
./emsdk install latest
./emsdk activate latest
. ./emsdk_env.sh

Configure and build MZX:

./config.sh --platform emscripten --enable-release
make -j8
make archive

Note that compiling MZX will make emsdk automatically install all required dependencies.

devkitARM, devkitA64, and devkitPPC

Follow the instructions here to install the devkitPro toolchains.

Note that if you're using MSYS2 (or a Linux distribution with pacman already installed), you can simply add the devkitPro repository to your pacman.conf and install devkitpro-keyring:

[dkp-libs]
Server = http://downloads.devkitpro.org/packages

[dkp-windows]
Server = http://downloads.devkitpro.org/packages/windows
