Hello,
I finally found why the umax_pp backend fails to compile on PPC arch.
When no libc is found (ie no HAVE_SYS_IO_H is defined) we fall back to including
asm/io.h , the kernel include holds the inb/out macros.
But on PPC arch, the whole include is protected behin a ifdef
__KERNEL__,
where i386 lets the part that defines inb/outb macros is outside it.
So it seems pointless to me to include asm/io.h on other arch than
i386.
To solve it, I'm considering to turn:
#ifdef HAVE_SYS_IO_H
# include <sys/io.h> /* GNU libc based Linux */
#elif HAVE_ASM_IO_H
# include <asm/io.h> /* older Linux */
#elif HAVE_SYS_HW_H
# include <sys/hw.h> /* OS/2 */
#else
#ifdef ENABLE_DIRECTIO
#undef ENABLE_DIRECTIO
#endif
#endif
to:
#ifdef HAVE_SYS_IO_H
# include <sys/io.h> /* GNU libc based Linux */
#elif HAVE_ASM_IO_H && defined __i386__
# include <asm/io.h> /* older Linux */
#elif HAVE_SYS_HW_H
# include <sys/hw.h> /* OS/2 */
#else
#ifdef ENABLE_DIRECTIO
#undef ENABLE_DIRECTIO
#endif
#endif
It seems to me that the qcam backend is also affected by this problem.
Any other idea ?
Regards,
Stef
