     Description:         Linux system headers

[Comment 1 Jakub Moc (RETIRED) 2006-02-05 06:02:44 UTC]

Needs a maintainer and a version bump to actually compile...

[Comment 2 Harald van Dijk (RETIRED) 2006-02-05 14:13:34 UTC]

jakub, thanks for re-assigning :)

The problem is actually with linux-headers; <linux/wait.h> is not C++-compatible. It relies on implicit conversions from void * to unsigned long *. Simple test program:
#include <linux/wait.h>
int main() {}

:)

The obvious patch, modifying wait.h to make these conversions explicit, works fine, but modifying the argument types may be a better way to go, I don't know.

[Comment 3 Harald van Dijk (RETIRED) 2006-02-05 17:05:22 UTC]

By the way, apparently g++ has a switch to make this a warning instead of an error (-fpermissive), so I made le use this and it should compile now, but it would still be great if this is not necessary.

Unfortunately that won't work since different archs have different function prototypes for test_bit and test_and_set_bit. This is fixed in the 2.6.15 headers; attaching a patch for the 2.6.11 headers.

[Comment 5 Tim Yamin (RETIRED) 2006-04-19 15:35:04 UTC]

Patch added to 2.6.11-r5 headers, reopen bug if you still get problems.
