After many wrong turns, I have managed to locate, download, and install the latest available (as far as I know) beta version of DJ Delorie's DJGPP development environment. This is the 30 November 2003 build of the DJGPP 2.04 beta, installed with the DJGPP ports of GCC 4.12 (GNU release 13 February 2007, port release 31 March 2007) and GMP 4.12 (ports posted 3 January 2003).

The base directory is http://www.delorie.com/pub/djgpp/ . I chose to download the following files, locations shown relative to the base directory:

unzip32.exe    /current
djdev204.zip   /beta/v2
bnu217b.zip    /beta/v2gnu
gcc412b.zip    /beta/v2gnu
gpp412b.zip    /beta/v2gnu
gmp412b.zip    /current/v2gnu
gmp412d.zip    /current/v2gnu
gdb64b.zip     /beta/v2gnu
txi48b.zip     /beta/v2gnu
man13b.zip     /beta/v2apps
faq230b.zip    /current/v2

Create a directory c:\djgpp (if you already have one for DJGPP 2.03, rename it DJGPP203 or delete it; the files should not be mixed). Unzip the zipfiles (using unzip32.exe) into c:\djgpp, preserving the directory structures and long file names (with exceptions as explained in the DJGPP documentation). The unzip32.exe utility can be placed in the c:\djgpp\bin directory, or in another utility directory in your path (e.g., c:\windows). These instructions are only rough guides; see the file README.1ST in the DJGPP root directory for detailed instructions and additional information.

The above does not include sources, the utilities for emulating UNIX shells and utilities (needed for building packages such as GCC or GMP from source), or cross-compilers; these are available elsewhere under http://www.delorie.com/pub/djgpp/ . You will have to decide, based on the needs for your own development environment, exactly which archives to download and install.

ADDITIONAL NOTES

---

• The DJGPP 2.04 beta files are probably available on a number of mirrors as well, but I have not yet determined which ones.
• I have been unable to locate pre-built DJGPP binaries for the latest version (4.21) of GMP. You would need to download the sources and carry out the complex task of configuring, making, compiling, checking, and installing the libraries. This could be done within the DJGPP 2.04 environment, which would necessitate the downloading and installation of many additional utilities which emulate in DOS some of the functionality of a UNIX shell. Alternatively, the sources could be cross-compiled in Linux for the DJGPP environment, another complicated procedure outlined at the DJGPP site; see, for example, http://www.delorie.com/pub/djgpp/current/v2gnu/gcc412.README and http://www.delorie.com/pub/djgpp/rpms/*.* for some idea of what is involved. I have not yet attempted any such builds or cross-compiles with DJGPP.
• If you need the djp.exe executable file compression utility, it is part of http://www.delorie.com/pub/djgpp/deleted/v2misc/mlp107b.zip .
• The DPMI servers and stub utilities (CWSDPMI and PMODE/DJ) remain available in http://www.delorie.com/pub/djgpp/current/v2misc/csdpmi5b.zip and http://www.delorie.com/pub/djgpp/current/v2misc/pmode13b.zip . However, all recent versions of DOS and Windows have their own DPMI servers (HIMEM.SYS and EMM386.EXE, for example), so these utilities should be unnecessary.
