8# @BLURB: many extra (but common) functions that are used in ebuilds
9# @DESCRIPTION:
10# The eutils eclass contains a suite of functions that complement
11# the ones that ebuild.sh already contain. The idea is that the functions
12# are not required in all ebuilds but enough utilize them to have a common
13# home rather than having multiple ebuilds implementing the same thing.
14#
15# Due to the nature of this eclass, some functions may have maintainers
16# different from the overall eclass!

94# and where lib64 -must- be used on amd64 (for applications that need lib

194# or two patches. 266# @USAGE: [options] [patches] [dirs of patches]
267# @DESCRIPTION:
268# epatch is designed to greatly simplify the application of patches. It can
269# process patch files directly, or directories of patches. The patches may be
270# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
271# the -p option as epatch will automatically attempt -p0 to -p5 until things
272# apply successfully.
195# 273#
196# It should work with .bz2, .gz, .zip and plain text patches. 274# If you do not specify any patches/dirs, then epatch will default to the
197# Currently all patches should be the same format. 275# directory specified by EPATCH_SOURCE.
198# 276#
199# You do not have to specify '-p' option to patch, as it will 277# Any options specified that start with a dash will be passed down to patch
200# try with -p0 to -p5 until it succeed, or fail at -p5. 278# for this specific invocation. As soon as an arg w/out a dash is found, then
279# arg processing stops.
201# 280#
202# Above EPATCH_* variables can be used to control various defaults, 281# When processing directories, epatch will apply all patches that match:
203# bug they should be left as is to ensure an ebuild can rely on 282# @CODE
204# them for. 283# if ${EPATCH_FORCE} != "yes"
205#
206# Patches are applied in current directory.
207#
208# Bulk Patches should preferibly have the form of:
209#
210# ??_${ARCH}_foo.${EPATCH_SUFFIX} 284# ??_${ARCH}_foo.${EPATCH_SUFFIX}
285# else
286# *.${EPATCH_SUFFIX}
287# @CODE
288# The leading ?? are typically numbers used to force consistent patch ordering.
289# The arch field is used to apply patches only for the host architecture with
290# the special value of "all" means apply for everyone. Note that using values
291# other than "all" is highly discouraged -- you should apply patches all the
292# time and let architecture details be detected at configure/compile time.
211# 293#
212# For example: 294# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
295# for patches to apply.
213# 296#
214# 01_all_misc-fix.patch.bz2 297# Refer to the other EPATCH_xxx variables for more customization of behavior.
215# 02_sparc_another-fix.patch.bz2
216#
217# This ensures that there are a set order, and you can have ARCH
218# specific patches.
219#
220# If you however give an argument to epatch(), it will treat it as a
221# single patch that need to be applied if its a file. If on the other
222# hand its a directory, it will set EPATCH_SOURCE to this.

555# of these three directories to exist will be the one to use, ignoring
556# any more general directories which might exist as well. They must end
557# in ".patch" to be applied.
558#
559# User patches are intended for quick testing of patches without ebuild
560# modifications, as well as for permanent customizations a user might
561# desire. Obviously, there can be no official support for arbitrarily
562# patched ebuilds. So whenever a build log in a bug report mentions that
563# user patches were applied, the user should be asked to reproduce the
564# problem without these.
565#
566# Not all ebuilds do call this function, so placing patches in the
567# stated directory might or might not work, depending on the package and
568# the eclasses it inherits and uses. It is safe to call the function
569# repeatedly, so it is always possible to add a call at the ebuild
570# level. The first call is the time when the patches will be
571# applied.
572#
573# Ideally, this function should be called after gentoo-specific patches
574# have been applied, so that their code can be modified as well, but

1008# basically look for the first lseek command (we do the strings/grep because
1009# sometimes the function call is _llseek or something) and steal the 2nd
1010# parameter. here is an example:
1011# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1012# lseek
1013# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin

1395# either be performed using pkg-config or doesn't introduce additional
1396# flags.

1398# If '--modules' argument is passed, .la files for modules (plugins) are
1399# removed as well. This is usually useful when the package installs
1400# plugins and the plugin loader does not use .la files.

1402# If '--all' argument is passed, all .la files are removed without
1403# performing any heuristic on them. You shouldn't ever use that,
1404# and instead report a bug in the algorithm instead.
1405#
1406# The .a files are only removed whenever corresponding .la files state
1407# that they should not be linked to, i.e. whenever these files
1408# correspond to plugins.
1409#
1410# Note: if your package installs both static libraries and .pc files
1411# which use variable substitution for -l flags, you need to add
