\A{source} Building NASM from Source
|
|
|
|
The source code for NASM is available from our website,
|
|
\w{https://www.nasm.us/}, see \k{website}.
|
|
|
|
\H{tarball} Building from a Source Archive
|
|
|
|
The source archives available on the web site should be capable of
|
|
building on a number of platforms. This is the recommended method for
|
|
building NASM to support platforms for which executables are not
|
|
available, if you do not require changing the source code.
|
|
|
|
The preferred build platforms are development environments which
|
|
support POSIX (Unix)-style tools (a "POSIX environment"). For Windows,
|
|
MSYS2 (\w{https://www.msys2.org/}) is such a development
|
|
environment. Normally either \c{gcc} or \c{clang} is used as the
|
|
compiler, but it is also possible to use MSVC with a POSIX wrapper
|
|
like \W{https://github.com/swig/cccl}\c{cccl} from the SWIG project.
|
|
|
|
In a POSIX environment, run:
|
|
|
|
\c sh configure
|
|
\c make
|
|
|
|
A number of options can be passed to \c{configure}; see
|
|
\c{sh configure --help}. In particular, the \c{--host} option can be
|
|
used to cross-compile NASM to run on another host system.
|
|
|
|
For non-POSIX environments, a set of makefiles for a handful of other
|
|
environments are also available; please see the file
|
|
\c{Mkfiles/README}. These makefiles are generally considered
|
|
unreliable, as we have very little ability to test them.
|
|
|
|
The \c{.zip} version of the source archive has DOS/Windows line
|
|
endings (\c{CR LF}), which many Unix/POSIX systems will not
|
|
recognize. To extract the \c{.zip} version on such a system, use
|
|
\c{unzip -a}. The \c{.tar} versions of the source archive has POSIX
|
|
line endings (\c{LF}).
|
|
|
|
|
|
\H{buildtools} Optional Build Tools
|
|
|
|
The following additional tools are required to build specific
|
|
subsystems, to build from the \c{git} repository, or if the sources
|
|
are modified.
|
|
|
|
Note that some of these tools will have their own dependencies.
|
|
|
|
Make sure all tools are available in your \c{PATH} (or equivalent.)
|
|
|
|
To build the installer for the Windows platform:
|
|
|
|
\b The \i{Nullsoft Scriptable Installer} (\i{NSIS},
|
|
\w{https://nsis-dev.github.io/}).
|
|
|
|
To modify the sources, \e{or} to build the documentation:
|
|
|
|
\b A Perl interpreter (\w{https://www.perl.org/}).
|
|
|
|
\b Modules from CPAN (\w{https://www.cpan.org/}). The following Perl
|
|
modules are currently required, some of which will be bundled with the
|
|
Perl interpreter or into larger CPAN packages:
|
|
|
|
\& perlbreq.src
|
|
|
|
To build the documentation:
|
|
|
|
\b Either Ghostscript (\w{https://www.ghostscript.com/}) or Adobe
|
|
Acrobat Distiller (untested.)
|
|
|
|
\b The Google \e{Roboto} and \e{Roboto Mono} fonts, which are freely
|
|
available under the SIL Open Font License
|
|
(\w{https://github.com/google/roboto}).
|
|
|
|
To build the Unix man pages:
|
|
|
|
\b AsciiDoc (\w{https://asciidoc.org/}).
|
|
|
|
\b xmlto (\w{https://pagure.io/xmlto/}).
|
|
|
|
To build from the \c{git} repository on a POSIX platform:
|
|
|
|
\b GNU \c{m4}, \c{autoconf} and \c{autoheader}
|
|
(\w{https://www.gnu.org/}).
|
|
|
|
|
|
|
|
\H{buildopt} Building Optional Components
|
|
|
|
Install the required tools for the subsystem in question as described
|
|
in \k{buildtools}.
|
|
|
|
To build the documentation:
|
|
|
|
\c make doc
|
|
|
|
Building the documentation may not work in a non-POSIX environment.
|
|
|
|
To build the Windows installer:
|
|
|
|
\c make nsis
|
|
|
|
To build the Unix man pages:
|
|
|
|
\c make manpages
|
|
|
|
To build everything available on the current platform:
|
|
|
|
\c make everything
|
|
|
|
|
|
\H{git} Building from the \i\c{git} Repository
|
|
|
|
The NASM development tree is kept in a source code repository using
|
|
the \c{git} distributed source control system. The link is available
|
|
on the website. This is recommended only to participate in the
|
|
development of NASM or to assist with testing the development code.
|
|
|
|
Install the required tools as described in section \k{buildtools}.
|
|
|
|
In a POSIX environment:
|
|
|
|
Run:
|
|
|
|
\c sh autogen.sh
|
|
|
|
to create the \c{configure} script and then build as described in
|
|
\k{tarball}.
|
|
|
|
In a non-POSIX environment, use the tool-specific Makefiles
|
|
as described in \k{tarball}.
|
|
|
|
|
|
\H{modifysrc} Modifying the Sources
|
|
|
|
To build modified sources, you will need the tools described in
|
|
\k{buildtools}.
|
|
|
|
Some build system changes might not be possible without a POSIX
|
|
environment.
|
|
|
|
If you have modified the sources to change the embedded declarations
|
|
of warning classes, you may have to manually re-build the warning
|
|
catalog:
|
|
|
|
\c make warnings
|
|
|
|
This is not done automatically, as the tools do not have the ability
|
|
to automatically detect when it is necessary to do so.
