RTAI 24.1.2 doesn´t compile with kernel 2.4.0-test1

[Sven Garbade <garbade@psy.uni-muenchen.de>]

Hi there,

now I have downloaded a fresh copy of the 2.4.0-test1 kernel source tree
and got the following error message while compiling with RTAI 24.1.2:

gcc -D__KERNEL__ -I/usr/local/kernelsrc/linux-2.4.0/include -Wall
-Wstrict-prototypes -O2 -fomit-frame-pointer -fno-strict-aliasing -pipe
-mpreferred-stack-boundary=2 -march=k6   -c -o apic.o apic.c

apic.c:1721: (Each undeclared identifier is reported only once
apic.c:1721: for each function it appears in.)
apic.c: In function `acpi_exit':
apic.c:1813: `pm_active' undeclared (first use in this function)
make[1]: *** [apic.o] Error 1
make[1]: Leaving directory
`/usr/local/kernelsrc/linux-2.4.0/arch/i386/kernel'
make: *** [_dir_arch/i386/kernel] Error 2

What went wrong? Should I use another copy of RTAI or kernel source?

Thanks & regards, Sven
