[Bridge] SUSE 8.1 build failure

Hi

RE: bridge-utils-1.0.4, linux 2.4.21-241-athlon


I'm receiving the following groan when I attempt to build bridge-utils on
SUSE 8.1(linux 2.4.21-241-athlon)

Any help most appreciated.

Does anyone know where 'HZ' is declared in the 2.4.xx source?

grep is your friend:

# fgrep -r '#define HZ' /usr/src/linux
[...]
/usr/src/linux/include/asm-i386/param.h:#define HZ 100
[...]

so, you should insert

#include <asm/param.h>

into the module that doesn't compile.

[Gareth Wheelton]

I think 'libbride_private.h' was missing '#include <linux/hz.h>'

OK that's sorts out the compile, leaving the following link error:

gcc  brctl.o brctl_cmd.o brctl_disp.o  -L ../libbridge -lbridge  -o brctl
../libbridge/libbridge.a(libbridge_devif.o): In function `get_hz':
/usr/src/linux/include/linux/hz.h:19: undefined reference to `__HZ'
collect2: ld returned 1 exit status
make: *** [brctl] Error 1


Using 'nm' I found many modules under '/lib/modules/2.4.21-241-athlon'
referencing an undefined symbol '__HZ_R799069f6'. Maybe this is related?

My kernel is configured correctly i.e. CONFIG_BRIDGE=m


So where does '__HZ' live?


Cheers again.

Re: [Bridge] SUSE 8.1 build failure

[Stephen Hemminger]

The inline functions in libbridge_private.h expect HZ defined in /usr/include/asm/param.h
What does that look like on your system?
