Hi All,

Is there a symbol (like __U_BOO_T__) that is defined during U-Boot compilation and that I can test into my .c/.h source files?

I have a self-made library that is shared between the bootloader and the linux kernel.
Obviously the source paths and includes are different in the two environment and I need to choose the correct code on the basis of the target enviroment.

In the linux kernel I can use symbol like "__LINUX__" to understand that the actual compilation is referred to the Linux Kernel... but I don't find an similar symbol define in U-Boot.

I would write code like:
...
#if defined(__U_BOOT__)
/* U-boot specific code */
...
#elsif defined(__LINUX__)
/*Kernel specific code */
#endif
...

Is there a similar mechanism in U-BOOT building infrastructure? (anyway, can we insert a -D__U_BOOT__ in the compiler invocation?)

Thanks a lot,

luigi
