# Use "--without tests" to disable the testsuite.

# Use "--without annocheck" to disable the installation of the annocheck program.

%bcond_without annocheck

# Use "--with debuginfod" to force support for debuginfod to be compiled into

# the annocheck program.  By default the configure script will check for

# availablilty at build time, but this might not match the run time situation.

# FIXME: Add a --without debuginfod option to forcefully disable the configure

# time check for debuginfod support.

# Use "--with clangplugin" to build the annobin plugin for clang.

# Set this to zero to disable the requirement for a specific version of gcc.

# This should only be needed if there is some kind of problem with the version

# checking logic or when building on RHEL-7 or earlier.

%global with_hard_gcc_version_requirement 1

# # Do not build the annobin plugin with annotation enabled.

# # This is because if we are bootstrapping a new build environment we can have

# # a new version of gcc installed, but without a new of annobin installed.

# # (i.e. we are building the new version of annobin to go with the new version

# # of gcc).  If the *old* annobin plugin is used whilst building this new

# # version, the old plugin will complain that version of gcc for which it

# # was built is different from the version of gcc that is now being used, and

# # then it will abort.

#

# Suppress this for BZ 1630550.

# The problem should now only arise when rebasing to a new major version

# of gcc, in which case the undefine below can be temporarily reinstated.

#---------------------------------------------------------------------------------

# [Stolen from gcc-python-plugin]

# GCC will only load plugins that were built against exactly that build of GCC

# We thus need to embed the exact GCC version as a requirement within the

# metadata.

#

# Define "gcc_vr", a variable to hold the VERSION-RELEASE string for the gcc

# we are being built against.

#

# Unfortunately, we can't simply run:

#   rpm -q --qf="%%{version}-%%{release}"

# to determine this, as there's no guarantee of a sane rpm database within

# the chroots created by our build system

#

# So we instead query the version from gcc's output.

#

# gcc.spec has:

#   Version: %%{gcc_version}

#   Release: %%{gcc_release}%%{?dist}

#   ...snip...

#   echo 'Red Hat %%{version}-%%{gcc_release}' > gcc/DEV-PHASE

#

# So, given this output:

#

#   $ gcc --version

#   gcc (GCC) 4.6.1 20110908 (Red Hat 4.6.1-9)

#   Copyright (C) 2011 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.
