I realize this may be a really dumb question. Please humor me:
True or False: The only way to compile a program to run on a VxWorks platform is to purchase a development environment like Tornado or Workbench from WindRiver.
(I'm looking for an free/open-source solution to compile for a VxWorks platform.)
Outside of an academic license (which would use a VxWorks installation anyway), there is not any way to legally compile your code for a vxWorks platform.
Technically, you CAN obtain the GNU toolchain used to compile code for VxWorks.
The issue you will run into is that you won't have access to the header files necessary for compiling your code or the libraries to link against.
