odd, works fine here on amd64-linux. What host OS are you on again?

[Comment 3 Justin Lecher (RETIRED) 2008-11-11 18:19:17 UTC]

its an Suse 10.2. I tryed woth gcc 4.3 and 4.2 and it doesn't affects this.

[Comment 4 Justin Lecher (RETIRED) 2008-12-04 12:09:19 UTC]

Found out that it is a comon error on suse machines, which should be resolved including asm/param.h. Looks like the source of qlop.c does it, but...

[Comment 5 Justin Lecher (RETIRED) 2008-12-04 15:38:01 UTC]

Find a solution. The param.h from Suse in /usr/include/asm differs from the one in /usr/src/linux/include/asm/. I will past the diff. There the problem came from, as Hz isn't defined there. One can patch qlop.c although my one isn't the best I think, because it is very specific. Perhaps there could be something included in the ebuild which checks wether the patch is needed because one has the problem of no definition of Hz in the standard param.h.

fixed in cvs by discovering the value dynamically from the elf notes on the stack
