Yes i did... i always do and have never had a problem doing so before.
I will try building in a different directory though and report back.

Configure was:
./configure --prefix=/usr --enable-languages="c,c++"

Compiling with GCC 4.0.0, latest version GNU make.

BTW, can you CC to me please, im not on the list.

Thanks.

http://gcc.gnu.org/install/configure.html

To be honest I'm always surprised when it works at all.

Ok, that fixed it, thanks.

Maybe a warning should be included in the configure script that is shown when
poeple do run configure from the gcc source root?

Thanks again,

Bug 17383 is one of the more frequently reported issues with GCC 4.0.0, 
but building in the source directory is not considered release-critical.  
If someone wishes to submit a patch for that bug for 4.0 branch, I expect 
it could be considered for 4.0.2 but might be too risky for 4.0.1 now.

Like so? Tested by building outside the source directory and attempting
to build in the source directory. Did we want something like this for
mainline too?

We've historically put a lot of effort into making "./configure" work,
so I'd hate to snub anyone willing to work on it.  Perhaps an "at the
moment" in the message might be good.

Apparently it works in mainline right now. Maybe adjusting the release
notes for 4.0 to say that building in the source directory doesn't work
for the release at the moment?

I also changed the error message to read:

"... is not supported in this release"

Which might work and we can, of course, remove the error message if that
ever changes :)

OK?

I have no objections, not that I'm the release manager.

This is OK, even for 4.0.1.  It's also OK for mainline, and for 4.0.2, 
if you don't get it checked in before 4.0.1.

Checked it in today. Apparently mainline does this correctly right now,
though unless we plan on supporting it in the future an AC_MSG_WARN
might be good. "This may not work"

Looks like you're trying to build GCC in the source
folder itself - this is not supported (yet).

Try creating a separate build folder totally outside
of the expanded source tree and run configure
and then make there.

HTH,
Ranjit.

Configure command? I'll assume the host was i686-pc-linux-gnu.

In this case I'll bet you built in the source directory?
