Subject: hylafax: ftbfs with gcc-4.5

Date: Wed, 13 Jan 2010 01:04:31 +0000

Package: hylafax
Version: 2:6.0.3-5.1
Severity: normal
Tags: sid
User: debian-gcc@lists.debian.org
Usertags: ftbfs-gcc-4.5

The package fails to build in a test rebuild on at least amd64 with
gcc-4.5/g++-4.5, but succeeds to build with gcc-4.4/g++-4.4.
For the compiler version used, see:
http://lists.debian.org/debian-devel/2010/01/msg00230.html

The full build log can be found at:
http://people.debian.org/~lucas/logs/2010/01/08b/hylafax_2:6.0.3-5.1_lsid64b.buildlog
The last lines of the build log are cwat the end of this report.

The reason of the build failure is likely in the package (compiler or
linker message found in the build log), if this turns out as a gcc bug,
please reassign to the gcc-4.5 package. If the build ends with a
message "confused by earlier errors, bailing out", please
ignore it for now; these compiler errors are filed separately.

[Message part 1 (text/plain, inline)]

Mattias,

It looks like the development branch of GCC 4.5 has swithce a CPP
processor include file missing from just a wraning to an error.

The configure in HylaFAX is looking for the include files for the fchmod
declaration:
   $CXX -E t.c++ \
        | sed -e '/\/\*/,/\*\//d' -e 's;//.*$;;'
        | awk '{while($0~/[,(][ \t]*$/){printf"%s",$0;getline}print}' \
        | grep "fchmod[ ]*(.*)"

where t.c++ is (in this case):
  #include "unistd.h"
  #include "libc.h"
  #include "sys/stat.h"


Every other complier we've come across (GCC releases, Sun CC, Sco CC,
AIX CC, HUPX CC) issue pre-processor warnings on files not found (most
don't find "libc.h"), but none of them issue a fatal error that the GCC
HEAD branch is:
    t.c++:2:18: fatal error: libc.h: No such file or directory

For instance, any released GCC (4.4 and earlier) does:
    t.c++:2:18: error: libc.h: No such file or directory

But none of their pre-processors *stop* there, they finish including
sys/stat.h, which allows configure to see the fchmod declaration.  They
all exit with a non-zero exit, but all preprocess the rest of the input.

I'ld say this is a bug with GCC HEAD's pre-processor.

In Ubuntu, we've applied the attached patch to achieve the following:

  * debian/patches/901_fchmod-prototype.patch: glibc now
    includes an fchmod prototype which doesn't match hylafax's.
    (Closes: #565001)

We thought you might be interested in doing the same.

The proper fix is already in HylaFAX source:
    http://git.hylafax.org/HylaFAX?a=commitdiff;h=b0d873c950a72aa568d2fcfe7dbc8bb6e981c129

port.h shouldn't inlcude a declaration of fchmod if it's in the system.

Hi Arthur,
I found the very same problem when all Debian packages have been
recompiled using gcc 4.5. My original report against hylafax bugzilla is
http://bugs.hylafax.org/show_bug.cgi?id=924. I am now using the latest
released hylafax source on both Debian and Ubuntu. This source does not
include the patch provided upstream, so the problem is still there, but
Debian still use gcc 4.4, while Ubuntu maverick switched to 4.5.

Please note that the package has been tuned to fit Debian squeeze
release, so gcc 4.4.

Whenever hylafax will release a new version, I will create a new package
and upload it to Debian. The package will then forward to Ubuntu and
will not need that patch anymore (since it should be included upstream.)

Bye,
Giuseppe

The new Debian package solve this problem by using hylafax source more
recent than 6.0.5. The fix is already included in upstream source.
