If you want to take advantage of the new x86 assembly optimizations you need to make sure you have a current copy of NASM. Notes regarding specific platform issues are below.

Linux

You'll need perl and NASM in order to compile the latest MP3 decoder assembly optimizations. If you don't have NASM, you can still compile successfully, but you'll only be able to use some of the older optimizations written in gas. Under Linux you must first build the binary: ./configure make then install it (by default, /usr/local/bin which can be changed by providing the --bindir switch on the configure command line. do a ./configure --help for more info) : make install (zinf is installed to $(bindir), as set above) (plugins are installed to $(libdir)/zinf/plugins, as set above)

Build:

The main project file is located in the base\win32\prj directory. The file zinf.dsw organizes all the sub-projects and builds all the modules. As of the first release only MS Visual C++ 5.0 project files and nmake makefiles are provided. Feel free to add other development environments such as Borland and Metrowerks.

NOTE: In order for the build to succeed you will need to install the SGI STL, which you can download from here. The SGI STL is much more stable than the M$ STL.

Under MS VC++ you should open the file base\win32\prj\zinf.dsw and determine which build you want to do. If you want to take advantage of the assembly optimizations you need to have NASM installed and correctly configure DevStudio to use it. Select the "Tools/Options..." Menu and then choose the "Directories" tab. Select "Executables" in the "Show directories for..." ComboBox and enter the path where NASM lives on your computer (i.e. c:\temp). Once this is done select either NASM Release or Debug as the active configuration. Output will go to base\win32\prj. You can run Zinf from here or move it to another directory. Just make sure the plugins directory is in the same location.
