>Description:
When trying to build a new -CURRENT kernel with "make KERNCONF=CURLY buildkernel" in /usr/src, the build stops at:
...snip...

In file included from /usr/src/sys/sys/vnode.h:549,
from vnode_if.c:10:
vnode_if.h:17: syntax error before ')' token
vnode_if.h:18: warning: function declaration isn't a prototype
vnode_if.h: In function `VOP_ISLOCKED':
vnode_if.h:22: `vp' undeclared (first use in this function)
vnode_if.h:22: (Each undeclared identifier is reported only once
vnode_if.h:22: for each function it appears in.)
vnode_if.h:23: `td' undeclared (first use in this function)
...snip...
vnode_if.h is automatically produced by /sys/tools/vnode_if.awk in a command line like :
awk -f /usr/src/sys/tools/vnode_if.awk /usr/src/sys/kern/vnode_if.src -h
The output of my -CURRENT awk --version is : GNU Awk 3.1.0.
In the awk script vnode_if.awk, at line 222 in the "print out function" for loop, when i should be 1, it reaches 0.12477970123291015625 (!).
In the others cases, i takes its right value, eg:
i should be 0: i == 0
i should be 1: i == 0.12477970123291015625
i should be 2: i == 2
The output of the script, vnode_if.h, which is rejected by cc, look like:
...snip...
extern struct vnodeop_desc vop_default_desc;
struct vop_islocked_args {
struct vnodeop_desc *a_desc;
struct vnode *a_vp;
struct thread *a_td;
};
extern struct vnodeop_desc vop_islocked_desc;
static __inline int VOP_ISLOCKED(
struct vnode *vp,
^^^^^^^^^^^^^^^^^^^^^^
)
{
struct vop_islocked_args a;
int rc;
a.a_desc = VDESC(vop_islocked);
a.a_vp = vp;
a.a_td = td;
rc = VCALL(vp, VOFFSET(vop_islocked), &a);
return (rc);
}
...snip...
For more detail, you should find my full vnode_if.h and build logs at:
http://laurand.ath.cx/freebsd/
I have tested vnode_if.awk on a 4.5-STABLE with gawk 3.0.6 and it seems to work well.
So, I think that it could be a -CURRENT gawk 3.1.0 bug (?).
>How-To-Repeat:
make buildkernel on -CURRENT with a fresh src three, and gawk 3.1.0
>Fix:
coming back to gawk 3.0.6 :-((
