DJGPP的安装：（是英文，很简单，应该可以看懂。如果看不懂可以再提出来，大家可以帮忙翻译）
Installation Instructions for winXP
Use Explorer to create a folder for DJGPP. My Computer, Drive C, File->New->Folder, "DJGPP".
Use djgpp's unzip32.exe to unzip all the zips you downloaded into the C:\DJGPP folder. Don't unzip them each into separate folders - unzip them all to the same place. The directory structure inside each zip file should be preserved, so you end up with files like c:\djgpp\bin\gcc.exe and c:\djgpp\include\stdio.h
C:\> mkdir djgpp
C:\> cd djgpp
C:\DJGPP> unzip32 d:\tmp\djdev203.zip
C:\DJGPP> unzip32 d:\tmp\faq230b.zip
C:\DJGPP> unzip32 d:\tmp\rhid15ab.zip
C:\DJGPP> unzip32 d:\tmp\bnu2161b.zip
C:\DJGPP> unzip32 d:\tmp\gcc410b.zip
C:\DJGPP> unzip32 d:\tmp\gdb611b.zip
C:\DJGPP> unzip32 d:\tmp\gpp410b.zip
C:\DJGPP> unzip32 d:\tmp\mak3791b.zip
C:\DJGPP> unzip32 d:\tmp\txi48b.zip
When properly installed, you should have a c:\djgpp\bin directory, and in it should be at least gcc.exe, as.exe, and stubify.exe. If all the files are in c:\djgpp with no subdirectories, or you see directories like c:\djgpp\djdev203\, you need to delete everything and try a different unzip program.
Make sure you use the djgpp's unzip32, or some other unzip that doesn't support long file names. If you install with WinNT long file names, C++ programs won't compile. Another option is to use pkunzip instead (see the MS-DOS install instructions) or read the FAQ about the NameNumericTail registry key.
Right-click My Computer, select Properties. Select the Advanced tab, then the Environment Variables button. Edit the Path (or PATH, whichever exists) system variable to include C:\DJGPP\BIN at the front. (If you are not an administrator, add it to the PATH variable in the User Variables section, or add a new PATH user environment variable which contains only C:\DJGPP\BIN) Add a new variable DJGPP set to C:\DJGPP\DJGPP.ENV (system variable if possible, user variable if not an administrator) .
You'll need to close and reopen your MS-DOS windows for these changes to take effect.
Rather than edit your autoexec files and/or global environment, you may wish to create a djgpp shortcut instead. To do this, create a c:\djgpp\djgpp.bat that has lines like this:
@echo off
set PATH=c:\djgpp\bin;%PATH%
set DJGPP=c:\djgpp\djgpp.env
chdir c:\djgpp\mystuff (or any other directory)
command
(you can replace that last line with any other shell you'd like)
