As I'm not confident enough with the emerge process, I've not been able to actualy see where and how the LINUX_VERSION_CODE is defined. Using the commande below has been of no help. If you could tell me where to look at for the next time, I'll try to give a patch for this kind of bugs. Tia. find . -type f -exec grep LINUX_VERSION_CODE {} \; -print
As my use of DirectFB is to create a very small Gentoo based distro (for Business cards CD) I'm a bit suprised to end up in a game area. :) I would love to solve that problem by myself if only somebody could point me to a where to begin direction...
Well, the games team are the maintainers for DirectFB. In fact, SpanKY is the resident expert, so hopefully he'll pipe up shortly.
Ok Guys, sorry for all that noise. I still don't understand how this happened, but after emerging again the linux-headers the build now works fine. I saw that the LINUX_VERSION_CODE and KERNEL_VERSION were actually macros defined in linux/version.h and that's the reason why I decided to emerge the headers again. What I still don't understand is how these macros works, and why they failed before. But that's another story and I don't want to bother you with my slowly increasing knowledge. Sorry again.
