Last week someone mentioned that he’d like to run the ELLCC cross development tools on an operating system called “Windows”. Doing a little goolging proved that he might not be alone. Windows seems to be fairly popular, rivaling even Linux in popularity on the desktop. I decided to see what it would take to get ELLCC running on Windows. I spent the day Saturday installing MinGW-w64 on my development system and tweaking the ELLCC build rules to use it. The result is that I can now make a binary snapshot of ELLCC that runs on Windows which I have placed on the ftp site at ftp://ellcc.org/pub.

Here is an example of the results:

C:\cygwin\home\rich>ellcc\bin\ecc.exe -target x86_64-linux-eng hello.c

C:\cygwin\home\rich>ellcc\bin\ecc-size a.out
   text    data     bss     dec     hex filename
  15595     248    1608   17451    442b a.out

C:\cygwin\home\rich>

If I copy a.out to my Linux box, I get:

[~] dev% ellcc/bin/ecc-size a.out
   text    data     bss     dec     hex filename
  15595     248    1608   17451    442b a.out 
[~] dev% ./a.out 
hello world
[~] dev%

You can also use the work-in-progress ELK bare metal environment:

C:\cygwin\home\rich>ellcc\bin\ecc.exe -target arm-elk-engeabi hello.c -g

C:\cygwin\home\rich>ellcc\bin\ecc-size.exe a.out
   text    data     bss     dec     hex filename
  76923    2744   23096  102763   1916b a.out

C:\cygwin\home\rich>

If you have QEMU installed on your Windows box, you can run the bare metal executable as described in a previous blog post.

This makes it theoretically possible for me to do further development of ELLCC on Windows. I don’t think I will though.
