1) Download and install a source distribution.

2) Download and install NASM (http://www.web-sites.co.uk/nasm/).

3) Download and install the Win32 port of the SGI stl from:
   http://www.sirius.com/~ouchida/

4) Run Developer Studio and open the FreeAmp workspace located at:
   freeamp\base\win32\prj\freeamp.dsw

5) Put NASM in your path. Choose "Tools | Options" in DevStudio and
   go to the "Directories" tab.  Choose "Show Directories For" and
   select "Executable Files". Then add the directory where you have
   NASM.

6) The workspace is set up so that DevStudio automatically calculates
   dependencies between projects. This means that building the top
   level project (called simply "freeamp") will automatically build
   all the other projects you need to run the product. Set freeamp
   as your active project.

7) Build the freeamp project, and then run freeamp.exe. If you
   installed a shipping version of FreeAmp somewhere else, the first
   time you run the development version of FreeAmp, it will ask
   you whether you want to associate .MP3 files with the development
   version. It's up to you, I find it's nice to associate them with
   the development version.

8) If you get some errors compiling the dsoundcardpmo.cpp file, you likely
   have an old version (or rather, the stock DirectX headers that ship
   with MSVC 5.0) of DirectX installed. You can either update the DirectX
   SDK (which is a *very* large download) or you can grab the needed 
   dsound.h file from here: http://www.freeamp.org/misc/dsound.h


OTHER NOTES

Setting Breakpoints
-------------------

You may have trouble setting breakpoints when freeamp is not
currently being debugged. This is because you cannot set breakpoints
in DLLs for which DevStudio hasn't loaded the debug symbols. This is
common when you want to debug something that happens early in FreeAmp's
startup.

Once FreeAmp is completely up and running, all of the DLLs and debug
symbols are loaded and you can set breakpoints anywhere, but before that
time, not all the DLLs have loaded and you can't set breakpoints in some
files. You can fix this situation by telling DevStudio about the
DLLs you want to debug. Go to the "Project | Settings"
dialog for the "freeamp" project and choose the "Debug" tab.
Select "Additional DLLs" in the "Category" list and then enter
each DLL that you want to debug. Note that FreeAmp DLL files
do not end in .DLL -- they have funky names like something.ppp
and something.ppo. Most of them live in the freeamp\plugins
directory, and it wouldn't hurt to add them ALL to the "Additional
DLLs" category -- this will cause DevStudio to load the debug
symbols ahead of time, and you can set breakpoints before you
start debugging.


Building From the Command Line
------------------------------

You can automate the build (for those of you who don't like using
the DevStudio GUI) by exporting all the makefiles (select
"Project | Export Makefile" and then running Microsoft's NMAKE.EXE
on the freeamp makefile. You may need to twiddle a little bit
to get it to work, but it's not difficult.

If you are using DevStudio 6, or greater, you can also build from
the command line by using a command line similar to this one:

  MSDEV  drive:path\freeamp\base\win32\proj\freeamp.dsw /make all /out:Build-Log.txt
