Requirements

On Windows, you will need the following to build SPASM-ng:

  • Visual Studio with C++ support

    Visual Studio 2010 or newer is recommended, but it may be possible to downgrade. See http://stackoverflow.com/a/16196505 for more info.

    Note that if you're using Visual Studio 2010, SP1 or newer is required. Without the service pack, the build will fail.

    Visual Studio Express editions can be used for building. This include Express for Desktop, Visual C++ Express, etc.

    If you want to build with COM support, however, you will need the ATL include files. You can get these by either:

    • using Visual Studio Community (2015+, free w/restrictions);
    • using Visual Studio Professional;
    • installing Windows SDKs that contain the ATL include files, and reconfiguring the project accordingly.

On Linux, Mac OS X, and other *nix, you will need the following to build SPASM-ng:

Note that if you are using Linux, your distribution will likely have pre-built packages (and development packages) available to install. You should use these first before attempting to install the above libraries yourself.

Suggested packages for Ubuntu/Debian:

  • build-essential
  • libssl-dev
  • zlib1g-dev
  • libgmp-dev
  • checkinstall (optional, only if you want to build Debian packages - .deb files)

If building without app signing support (see Building in this document), GMP and OpenSSL are not required.

To run the tests, you will also need Python 3.1+. Versions below Python 3.1 will not work!

Building

On Windows, simply build with the included Visual Studio project file.

If you wish to build with COM support, you must:

  • define SPASM_NG_ENABLE_COM globally within the Visual Studio project;
  • ensure that ATL include files are accessible.

On Linux, Mac OS X, and other *nix, simply build by running:

# Git users: run this to update the version
# ONLY RUN THIS IF YOU ARE USING GIT
make version

# Now build!
make

# Optional: install SPASM-ng (you may need sudo/su/root):
make install

To disable app signing support in your binary (thus eliminating the dependencies on OpenSSL and GMP), define NO_APPSIGN when invoking make:

make NO_APPSIGN=1

For Debian systems, you can run the following to create a Debian package:

# You should "make clean" before running this!
make clean

# Create a Debian package (builds opt target):
make debian

Other Makefile commands:

# You should "make clean" before running any of this!
make clean

# Build with -static (static linking, bigger binary due to
# including libraries):
make static

# Build with -O3 optimization:
make opt

# Build with both -static and -O3 optimization:
make opt-static

# Create tarball of spasm-ng binary (builds opt-static target):
make tar

Cross-compiling can be enabled by simply setting the cross-compiling prefix, e.g.

make CROSS_COMPILE=i686-w64-mingw32-

Documentation

The program accepts standard Z80 assembly and eZ80 assembly.

SPASM command line help shown below:

SPASM-ng Z80 Assembler by Spencer Putt and Don Straney


spasm [options] <input file> <output file>

Options:
-E = Assemble eZ80 code
-T = Generate code listing
-C = Code counter mode
-L = Symbol table mode
-S = Stats mode
-O = Don't write to output file
-I [directory] = Add include directory
-A = Labels are cAse-sensitive
-D<name>[=value] = Create a define 'name' [with 'value']
-N = Don't use colors for messages
-V <Expression> = Pipe expression directly into assembly

Added features for eZ80 code include:

  • The .ASSUME ADL={0 or 1} directive for specifying 16-bit or 24-bit code (24-bit is the default).
  • The .DL and .LONG directives for including 24-bit data.
  • Mode-change suffixes available for all instructions, as seen in the eZ80 manual.
