            Bug ID: 65535
           Summary: powerpc64-freebsd build failure
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: msebor at gcc dot gnu.org

Building gcc for powerpc64-freebsd fails with the error below.  Looks like the
FBSD_MAJOR macro is defined to nothing:

$ grep FBSD_MAJOR ./gcc/tm.h
#ifndef FBSD_MAJOR
# define FBSD_MAJOR

Defining the macro to an integer such as 10 lets the build succeed.

Here a native build seems to succeed, right now in stage three with sources
from today.

[tritium:head/objdir/gcc] andreast% grep -i fbsd_major *
Makefile:tm_defines= LIBC_GLIBC=1 LIBC_UCLIBC=2 LIBC_BIONIC=3 FBSD_MAJOR=11
config.log:tm_defines=' LIBC_GLIBC=1 LIBC_UCLIBC=2 LIBC_BIONIC=3 FBSD_MAJOR=11'
config.status:S["tm_defines"]=" LIBC_GLIBC=1 LIBC_UCLIBC=2 LIBC_BIONIC=3
FBSD_MAJOR=11"
tm.h:#ifndef FBSD_MAJOR
tm.h:# define FBSD_MAJOR 11

FBSD_MAJOR is defined during configure time:

config.gcc:line 666

  fbsd_major=`echo ${target} | sed -e 's/.*freebsd//g' | sed -e 's/\..*//g'`
  tm_defines="${tm_defines} FBSD_MAJOR=${fbsd_major}"

Can you give me some details about your setup/build?

Unfortunately the build fails with:

/usr/local/bin/ld: libbackend.a(tree-diagnostic.o): bad reloc symbol index
(0x10000 >= 0x39) for offset 0x3ee6 in section `.debug_info'
libbackend.a: error adding symbols: Bad value
collect2: error: ld returned 1 exit status
/export/devel/net/src/gcc/head/gcc/gcc/c/Make-lang.in:71: recipe for target

gmake[3]: Leaving directory '/export/build/src/gcc/head/objdir/gcc'
Makefile:4444: recipe for target 'all-stage3-gcc' failed

But this is independent to your report.

This isn't powerpc64 specific.  I didn't specify a FreeBSD version when
configuring gcc (i.e., I set --target=powerpc64-freebsd) assuming configure
would default to some supported version.  The code in gcc/config.gcc then
results in FBSD_MAJOR being defined but empty. The patch below lets me build
stage1 (I don't have a FreeBSD sysroot to do a full bootstrap):

index cb08a5c..c668738 100644

If supplying a default version doesn't seem like a good idea another option
might be to fail early, during the configure step.

Here my patch:

https://gcc.gnu.org/ml/gcc-patches/2015-04/msg00839.html

I do not like to hardcode a version number. Would mean to update when needed..

The important thing here is, if you build a cross compiler make sure that the
binutils and the gcc target match, including a major version number.

E.g: the binutils --target=amd64-unknown-freebsd10.1 must be equal to the gcc
--target=amd64-unknown-freebsd10.1.

It doesn't work if you give a target w/o version number to binutils and one
with version number to gcc configury.

The mentoned patch was tested on a CentOS -> amd64-unknown-freebsd11.0 cross
also on native FreeBSD (armv6/hf, amd64).
