Hello
I'm trying to report this error and I'm not sure if anybody knows about 
this yet. Can somebody please tell me exactly what the error is.

Based on looking at event-top.c, you seem to be compiling on a system
where HAVE_SBRK isn't #defined.  Does your system have the `sbrk'
system call?

There is a missing ifdef in there, I guess you must be one of the few
(the only one) triggering this.

Hmm, might as well pull that into the 5.2 branch.

Re: *** [ser-tcp.o] Error 1 on alpha!

[Andrew Cagney]

Hmm,

The problem below is from something other than the patch.  I suspect a 
configuration / host problem - for some reason, there isn't a definition 
of FIONBIO available?

[Matthew H Bemis]

Hello,
I agree it is not caused by the patch, but not many people test their
patches on alpha.
We download from cvs every day and build this.  We have a stable build
system.  I can give you a cvs snapshot of when we took the source code from
cvs if you'd like, and I can also provide any other information about the
host machine upon request.
I have all of the build logs available too if you'd like to see them got to:
for alpha goto:
ftp://alpha9.crl.dec.com/pub/autobuild/results/alpha6/basic-gcc_2.95.3/nativ
e/toolchain/20020622-05:21:38-F/
and click on the X-configure.blog log to see the configuration,and the
X-make.blog for the compilation error

to see alpha daily builds goto:
http://handhelds.org/projects/toolchain/autobuild/build-results.php3

Would you have a time for the last successful build?

I suspect that the unfortunate reality is that someone is going to have 
to roll up their sleeves and try to build GDB while logged into an Alpha 
GNU/Linux system.  Only that way can the look at the relevant headers 
and figure out why things are going wrong.  ser-*.c is pretty generic so 
I'm puzzled as to why that doesn't build.

Anyway this:

> /mnt/buildsys/source/toolchain/gdb/ser-tcp.c: In function `net_open':
> /mnt/buildsys/source/toolchain/gdb/ser-tcp.c:67: warning: implicit declaration of function `strncmp'

> /mnt/buildsys/source/toolchain/gdb/ser-tcp.c:83: warning: implicit declaration of function `atoi'

suggests that something is skewiff.  ser-tcp.c unconditionally includes 
"gdb_string.h" and that pulls in either <string.h> or <strings.h> so 
should have those declarations visible?

Hmm, check the generated config.h for something strange.

[Matthew H Bemis]

Elana,
Mike is building on an alphaev56, and he is building with the
bootstrap-gcc_3.0.4 baseline.
we'll try the patch tomorrow.
we'll let you know how it goes.
thanks!
