           Summary: Compilation cannot find file asm/errno.h
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: mancilla@cse.unsw.edu.au


Hi,
I recently upgraded from Ubuntu 10.10 to 11.04, and upon the first attempted
compilation of 4.7.0, it crashed complaining of:

------------------------------------------------------------------------------
In file included from /usr/include/bits/errno.h:25:0,
                 from /usr/include/errno.h:36,
                 from

directory
compilation terminated.

make[1]: *** [stage1-bubble] Error 2
make[1]: Leaving directory `/home/mancilla/current/soft/src/gcc-build-latest'
make: *** [all] Error 2

-------------------------------------------------------------------------------

After much browsing mailing lists and bug reports everywhere, it seems that the
problem lies on the linux headers (?). The directory in question used to be
/usr/include/linux and in my case it is now /usr/include/x86_64-linux-gnu.
After following sugestions, I tried setting CPPFLAGS, CFLAGS and CXXFLAGS to
-I/usr/include/x86_64-linux-gnu and then "-isystem
/usr/include/x86_64-linux-gnu" when calling configure and the result was: at
first CPPFLAGS was ignored and the same error accurred (setting CPPFLAGS). Then
stage 1 completed and the same error occurred at the begining of stage 2
(setting just CFLAGS). Setting both CFLAGS nad CXXFLAGS got the compilation
further, but still a similar error. In this last attempt, it did not make a
difference whether
it was -I or -isystem:

----------------------------------------------------------------------------

In file included from /usr/include/bits/errno.h:25:0,

make[1]: *** [stage2-bubble] Error 2
make[1]: Leaving directory `/home/mancilla/current/soft/src/gcc-build-latest'
make: *** [all] Error 2

-----------------------------------------------------------------------------

I'm not too sure it this is the right place for reporting this. But it seems
that the compilation needs to know where is errno.h. Please let me know if it
is necessary to attach the full log of the build.

Any advice would be greatfully appreciated.

Blanca

I succeeded in compiling by serring the following environment variables:

export C_INCLUDE_PATH=/usr/include/x86_64-linux-gnu
export CPLUS_INCLUDE_PATH=/usr/include/x86_64-linux-gnu

is this the right way?

Shouldn't this be Component=bootstrap not c++ ?

I assume the linux-libc-dev package is installed? That provides asm/errno.h

What compiler are you using to bootstrap? If it's the standard system compiler
it should know to look in /usr/include/x86_64-linux-gnu, if not then it's a bug
in the Ubuntu gcc package

What is the output of "gcc -v -x c /dev/null -c" ?

This is an Ubuntu packaging issue (or you lack some package), not a GCC issue,
as errno.h is a standard header.

Yes, sorry.

Yes that is installed.

4.5.2, which came with the distribution.

Is is attached.

A bug in the Ubuntu gcc package confirms the fact that problems started after
the upgrade. Thanks for clearing things out.

Blanca

On Ubuntu 11.10 (oneiric), linux-libc-dev installs to
/usr/include/i386-linux-gnu (or whatever your arch is, I suspect).  In order to
get gcc to build, I had to symlink the dir:

sudo ln -s /usr/include/i386-linux-gnu/asm /usr/include/asm

Whether it's a bug in ubuntu gcc, or the libc-dev package, I dunno.

I had the same problem, and fixed it by copying "/usr/include/i386-linux-gnu/"
from another 32bit system to your current system.

I your system doesn't have /usr/include/i386-linux-gnu/, GCC cannot find the
right PATH to i386-linux-gnu

This still happens with Ubuntu 12.04.3 and gcc 4.8.2. Are you sure this is just
ubuntu error?
I had to install linux-libc-dev:i386, but I'm building on 64 bit system for the
host (which has properly installed linux-libc-dev that existing gcc has in
include search path).
