本文提供了DJGPP编译器的基本安装步骤及所需文件列表，适用于DOS及Windows 95到XP的1x86平台。介绍了如何下载安装包、设置环境变量，并验证安装是否成功。

The DJGPP compiler is a DOS port of the unix GCC compiler for DOS (or windows 95->XP) 1x86 platforms.

The minimum set of files you need to build my jukebox projects are:

Path	Description	Bytes	Download
v2/readme.1st	Installation instructions	22,141	USA UK
v2/copying.dj	DJGPP Copyright info	2,084	USA UK
unzip32.exe	Unzip tool (if you need one)	96,644	USA UK
v2/djdev203.zip	DJGPP Basic Development Kit	1,530,778	USA UK
v2gnu/bnu215b.zip	Basic assembler & linker	3,508,408	USA UK
v2gnu/gcc343b.zip	Basic GCC compiler	3,781,700	USA UK
v2gnu/mak3791b.zip	Make (to processes makefiles)	272,798	USA UK
v2misc/csdpmi5b.zip	CWSDPMI - DPMI server (to run under "real" DOS)	54,550	USA UK

To install these files:

Download these files (just click on the links)
Create a new directory to install them into (eg c:/djgpp, avoid spaces, and stick to 8.3 names)
```
mkdir c:/djgpp
```

Unzip the files to this directory (creating the tree)

unzip32.exe bnu215b.zip -d c:/djgpp
unzip32.exe csdpmi5b.zip -d c:/djgpp
unzip32.exe djdev203.zip -d c:/djgpp
unzip32.exe gcc343b.zip -d c:/djgpp
unzip32.exe mak3791b.zip -d c:/djgpp

Let the tools know where the djgpp.env file is:
```
set DJDIR=c:/djgpp
```
Add the bin directory to your path,
```
PATH=%DJDIR%/bin;%PATH%
```

Just to check

gcc -v

Should return a few lines, ending with

gcc version 3.4.3

Of course you don't have to install the tools into c:/djgpp, but you should avoid spaces in the path name, and keep each level below 8 characters (because the tools run with 8.3 filenames, and you can get aliasing otherwise).
