what is the proper way to build with fedora rawhide/gcc-5.0?

what is the proper way to build with fedora rawhide/gcc-5.0?

[Robert P. J. Day]

  i asked about this a few weeks ago, finally getting back to it ...
for better or worse, i'm running fedora rawhide, updated to the point
where i have gcc-5.0.0:

$ gcc --version
gcc (GCC) 5.0.0 20150208 (Red Hat 5.0.0-0.10)
Copyright (C) 2015 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
$

which causes a number of build issues trying to build for something as
simple as qemux86.

  first, there is a linemarkers issue with gcc-5.0 that i got around
by adding to local.conf:

  CPPFLAGS_append= " -P"

and there were two native build issues due to gcc-5.0 being far
pickier with warnings that i sidestepped with the cheap hack:

  ASSUME_PROVIDED += "elfutils-native"
  ASSUME_PROVIDED += "binutils-native"

at this point, the build was almost complete when i hit another
compile error for udev on the target:

DEBUG: SITE files ['endian-little', 'bit-32', 'ix86-common',
'common-linux', 'common-glibc', 'i586-linux', 'common']
DEBUG: Executing shell function do_compile
NOTE: make -j 8
make: *** No rule to make target '/linux/input.h', needed by

  in any event, is there a *preferred* way to build using fedora
rawide at this point?

Blimey, gcc 5 looks like a barrel of laughs.  Is installing gcc 4.x
alongside 5.0 possible, and then set BUILD_CC etc?

This should not be required. Can you post the failing package with error details
it should be fixed.

There is 2.25 update available on my contrib tree.
http://git.openembedded.org/openembedded-core-contrib/log/?h=kraj/master
should help with binutils.

that seems to be unrelated to gcc 5.0 on host. May be you have a different issue there.

I think people will care when fedora 22 comes out later this summer or may be when they have beta’s coming out.

  for people not sure what i'm talking about, this issue was
identified back in feb at red hat:

https://lists.fedoraproject.org/pipermail/devel/2015-February/207549.html

the package that initially tripped me up was ncurses-native, and
ncurses is indeed mentioned in that lengthy list of packages.

  i can try another build without "-P" and note the packages that fail
if that's useful, although i assume anyone else can trivially do the
same thing.

  i *think* i mentioned earlier that the first failing package build
is ncurses-native:

  this appears to be related to the issues listed in this post
describing a mass rebuild of fedora packages with gcc-5.0.0:

https://lists.fedoraproject.org/pipermail/devel/2015-February/207549.html

particularly this:

"Main offender this time is probably the gnu11 change that entails
different inline semantics, enables some warnings by default, bumps
the __STDC_VERSION__, and so on.  Hopefully it won't take too long
till these packages catch on. Many packages were not prepared for the
new major version of GCC.  There's also been quite a lot of churn
because of the preprocessor now emitting linemarkers in the output
when the -P option is not turned on.  The C++ compiler now rejects
some code that it used to accept.  Furthermore, GCC 5 has a batch of
new warnings, which, combined with -Werror, caused some additional
failures."

  sure enough, down that page, ncurses and a bunch of other packages
are identified as having the issue:

"these packages failed to build because of the changes in the
preprocessor; gcc started to generate line directives to better detect
whether a macro tokens come from a system header - see
http://gcc.gnu.org/PR60723 The fix is to use the -P option if the code
isn't prepared to deal with such directives."

  i see that your oe-contrib repo has a newer version of binutils, but
not of ncurses, although your ncurses SRC_URI is different. anyway,
this is just what i've tripped over lately on my rawhide system.

  FYI, your version of ncurses-5,9 with a more upstream SRC_URI
appears to solve the problem with building ncurses-native.

  ok, i finally have a full build for qemux86/core-image-minimal.
things i did:

* wiped the old kernel tarball from my local source mirror -- not
  sure why that fixed the kernel issue but a fresh download seems
  to have done the trick.
* removed the above CPPFLAGS_append line from local.conf
* used khem's ncurses recipe
* left the two ASSUME_PROVIDED lines where they were, out of sheer
  laziness since they seem to work.

  enough excitement for one day ...

my branch will have more fixes for packages that are specifically
originating from gcc5 work. Some has already been merged some more are
to come
