DJGPP

This got me into Linux. First I was installing DJGPP on Windows, then I followed the trail back to GCC, then I found out all about all the great free stuff the GNU toolchain provided, and ended up installing Slackware from a stack of floppies that I had downloaded painstakingly over a 14.4kbps modem.

DJGPP was where as a kid I learned C++, inline assembly with advanced optimizations and produced my first real-time 3D engine (perspective-correct Gouraud shaded textured polygons with Z-buffer and view frustum culling, no HW acceleration). In RHIDE as well. Thanks DJ!

This was the toolchain used to build and ship Quake. Prior to that id, like everyone used Watcom C/C++ with the DOS/4GW extender.

DJ is still very much around. He works at Red Hat on toolchain things, and is also helping out with the RISC-V port of Fedora.

This brings back memories! Back when I wanted to get into programming, I had no idea where to start. I found a book about C++ at the library and it was one of the only programming languages I had heard about before (little did I know!). I believe it was &quot;Teach yourself C++ in 21 days&quot; or something like that. It came with a copy of DJGPP on CD-ROM.<p>Looking back it&#x27;s amazing how much easier it is to learn stuff nowadays. The internet is truly a blessing.

This and the &quot;C Programming Language, 2nd Edition&quot; was how I taught myself C back in the mid 90&#x27;s.

These days there is also a 16-bit GCC port to DOS (<a href="https:&#x2F;&#x2F;github.com&#x2F;tkchia&#x2F;gcc-ia16">https:&#x2F;&#x2F;github.com&#x2F;tkchia&#x2F;gcc-ia16</a>). I never encountered one of those back in the day? I think the compiler itself does not run in 16-bit DOS though.<p>Anyone interested in compiling for DOS (32-bit or 16-bit) should also check out Free Pascal.

I learned C on this compiler. Very fond memories

Many happy memories learning to program C on DOS&#x2F;Windows back in the 90s. This little website (which looks the same as back then) was my go to! :)

Used this for a camera project in 1992-3. We had a 16MB machine and our images were 14MB, so we couldn&#x27;t squeeze in to Windows 3.1. Worked a treat, and was much easier to work in the flat memory space it offered IIRC.

For the longest time I had memorised the weird dpmi commands to enable 13h mode and get the screen buffer address. I don&#x27;t think I can remember anymore.<p>Good times :)<p>Also the one place I learned to use `info`, as it had a very good reference for many of the libc stuff, though for some reason I never really continued to use it even if its available on linux.

Makes me miss old school tools like Dev-C++ and MSVC 6.0<p>Courier was so readable.

I recently ported this to Nix if anyone is itching to try it.<p><a href="https:&#x2F;&#x2F;github.com&#x2F;NixOS&#x2F;nixpkgs&#x2F;pull&#x2F;237151">https:&#x2F;&#x2F;github.com&#x2F;NixOS&#x2F;nixpkgs&#x2F;pull&#x2F;237151</a>

I was using it in the early 90&#x27;s. At that time if you wanted to port your C&#x2F;C++ application to multiple platforms, one option would be: - gcc on linux - djgpp on MSDos - emx+gcc on OS&#x2F;2 [1]<p>[1] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;EMX_(programming_environment)" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;EMX_(programming_environment)</a>

Also remember Rhide IDE.<p>(Looks like the official Rhide website is down&#x2F;gone?).

Almost didn&#x27;t recognize it as &quot;Djgpp&quot;. As DJGPP however, it kicks off a lot of memories instantly!

Is this still being developed?<p><a href="https:&#x2F;&#x2F;www.delorie.com&#x2F;pub&#x2F;djgpp&#x2F;current&#x2F;v2&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.delorie.com&#x2F;pub&#x2F;djgpp&#x2F;current&#x2F;v2&#x2F;</a>

I used and loved it. As someone said, was my door on GNU utilities under MS-DOS and worked well! I forgotten it, so thank you for the link!

Conceptually this seems to be the opposite of wine. It allows programs written for Linux to run under Microsoft Windows. Wine allows Windows programs to run under Linux.<p>Is there any way to use the synergy between them to make them work better ?

My first c++ compiler in 97

Fond memories of writing software with Allegro on DOS. Playing around with little games.<p>Definitely made getting into C&#x2F;C++ on Linux easier to have started with this tool chain.

Blast from the past!

The title should be all caps. From this page [1]:<p>&gt; Note: DJGPP is spelled all upper case when it would normally be capitalized, and all lower case otherwise. It is never correct to spell it ``Djgpp&#x27;&#x27;.<p>[1] <a href="https:&#x2F;&#x2F;www.delorie.com&#x2F;djgpp&#x2F;history.html" rel="nofollow">https:&#x2F;&#x2F;www.delorie.com&#x2F;djgpp&#x2F;history.html</a>
