I want to code for Haiku but I can’t find a VMWare image with dev tools.
There aren’t any development images at this point in time, but you could try Senryu.
Senryu should have everything you need and more.
The “pre-aLPHA IMAGE” http://haiku-files.org/raw/ , download haiku-alpha-r28303-raw.zip, this file has the development tools included.
