• Download and install Python: https://www.python.org/ftp/python/2....thon-2.7.6.msi (On older systems you need Windows Installer 2.0 Redistributable: http://www.microsoft.com/en-us/downl....aspx?id=11176 -> http://www.microsoft.com/en-us/downl...5695C5A2143=1#)
  
• Download and install SCons: http://sourceforge.net/projects/scon...2.exe/download -> http://netcologne.dl.sourceforge.net....2.0.win32.exe
  
• Download and install HTML help workshop: http://download.microsoft.com/downlo...4/htmlhelp.exe (This is optional, it will generate HTML documentation instead of CHM if you don't do this)
  
• Download and install VC 2003 Toolkit: Google:"VCToolkitSetup.exe" (v13.10.3052, 32952488 bytes or v13.10.3077, 32948392 bytes)
  
• Download Platform SDK February 2003 (5.2.3790.0):
  
  PHP Code:

  FOR /L %A IN (1,1,13) DO wget http://download.microsoft.com/download/platformsdk/sdk/update/win98mexp/en-us/3790.0/FULL/PSDK-FULL.%A.cab
wget http://download.microsoft.com/download/platformsdk/sdk/update/win98mexp/en-us/3790.0/FULL/PSDK-FULL.bat
wget http://download.microsoft.com/download/platformsdk/sdk/update/win98mexp/en-us/3790.0/FULL/extract.exe
REM (Download manually if you don't have wget) 

• Run PSDK-FULL.bat and then run the extracted setup and install the Core SDK and Internet Development SDK
  
• Download the Zlib library: http://nsis.sourceforge.net/Zlib (Zlib-1.2.7-win32-x86.zip)
  
• Download the NSIS source code, I used trunk r6644 r6646
  
• We are now ready to build, run "Set Windows 2000 Build Environment (Retail).lnk":
  
  
  PHP Code:

  REM VC2003TK linker sometimes dies with "fatal error LNK1158: cannot run 'cvtres.exe'" because SCons fails to put it in %path% so I'm fixing that with:
copy "%windir%\Microsoft.NET\Framework\v1.1.4322\cvtres*" "%VCToolkitInstallDir%\Bin\"

cd C:\NSIS\trunk
set PATH=%PATH%;C:\Program Files\HTML Help Workshop&REM
set ZLIB_W32=C:\NSIS\dep\zlib&REM

C:\Python27\Scripts\scons.bat MSTOOLKIT=yes VER_MAJOR=3 VER_MINOR=0 SKIPUTILS="NSIS Menu" SKIPPLUGINS=System PREFIX="c:\NSIS\NSIS" install 


If you want to build the system plugin you also need MASM. If you want to build the NSIS menu you need to download wxwidgets. I'm building everything here.
