1. Installing NASM from source (Unix, MacOS X; Windows - Cygwin; Windows - MinGW; DOS - DJGPP) 2. Installing NASM from source (Windows - MS Visual C++) 3. Installing NASM from source (DOS, Windows, OS/2 - OpenWatcom) 1. Installing NASM from source (Unix, MacOS X; Windows - Cygwin; Windows - MinGW; DOS - DJGPP) ================================================================ Installing NASM is pretty straightforward on Unix or Unix-like systems with a C compiler, Make, and standard shell tools installed, including MinGW for Windows (with MSYS installed) and DJGPP for DOS with the appropriate tools. Perl is not required for compiling unmodified sources from a tarball, but is required to build from git or for most source modifications. If you checked out source from git you will need to run autoconf to generate configure, otherwise you don't have to. $ sh autogen.sh Then run configure to detect your platform settings and generate makefiles. $ sh configure You can get information about available configuration options by running `sh configure --help`. If configure fails, please file a bug report with detailed platform information at: http://www.sf.net/projects/nasm/ If everything went okay, type $ make to build NASM, ndisasm and rdoff tools, or $ make everything to build the former plus the docs. You can decrease the size of produces executables by stripping off unnecessary information, to achieve this run $ make strip If you install to a system-wide location you might need to become root: $ su then $ make install optionally followed by $ make install_rdf Or you can $ make install_everything to install everything =) That's it, enjoy! 2. Installing NASM from source (Windows - MS Visual C++) ======================================================== The recommended compiler for NASM on Windows is MinGW (http://www.mingw.org/), but it is also possible to compile with Microsoft Visual C++ (tested with Visual C++ 2005 Express Edition.) To do so, start the "Visual C++ Command Shell", go to the directory where the NASM source code was extracted, and run: > nmake /f Mkfiles/msvc.mak We recommend MinGW over Visual C++ 2005 as we have found it to be more up to date with regards to C99 compliance, and we are increasingly using C99 features in NASM. 3. Installing NASM from source (DOS, Windows, OS/2 - OpenWatcom) ================================================================ NASM has been reported to build correctly with OpenWatcom 1.7 on the Windows and OS/2 platforms. In addition, it *should* work under DOS with the DOS4GW DOS extender, although the NASM developers recommend using DJGPP with the CWSDPMI DOS extender instead. A WMAKE make file is provided: > wmake -f Mkfiles\openwcom.mak ... where is "dos", "win32" or "os2".
