16 9# @DESCRIPTION:
17DESCRIPTION="Based on the ${ECLASS} eclass" 10# The eutils eclass contains a suite of functions that complement
18 11# the ones that ebuild.sh already contain. The idea is that the functions
19# This function simply returns the desired lib directory. With portage 12# are not required in all ebuilds but enough utilize them to have a common
20# 2.0.51, we now have support for installing libraries to lib32/lib64 13# home rather than having multiple ebuilds implementing the same thing.
21# to accomidate the needs of multilib systems. It's no longer a good idea
22# to assume all libraries will end up in lib. Replace any (sane) instances
23# where lib is named directly with $(get_libdir) if possible.

27 # CONF_LIBDIR wasnt supported until 2.0.51_pre18, so for all versions of
28 # portage prior to that lib would need to be used even if CONF_LIBDIR is
29 # set. dolib and friends will ignore CONF_LIBDIR in <2.0.51_pre20

37# the .so in /lib, and the .a in /usr/lib. What happens is that
38# in some cases when linking dynamic, the .a in /usr/lib is used
39# instead of the .so in /lib due to gcc/libtool tweaking ld's
40# library search path. This cause many builds to fail.

45# gen_usr_ldscript libfoo.so
46#
47# Note that you should in general use the unversioned name of
48# the library, as ldconfig should usually update it correctly

220# @FUNCTION: eshopts_push
221# @USAGE: [options to `set` or `shopt`]
222# @DESCRIPTION:
223# Often times code will want to enable a shell option to change code behavior.
224# Since changing shell options can easily break other pieces of code (which
225# assume the default state), eshopts_push is used to (1) push the current shell
226# options onto a stack and (2) pass the specified arguments to set.
227#
228# If the first argument is '-s' or '-u', we assume you want to call `shopt`
229# rather than `set` as there are some options only available via that.
230#
231# A common example is to disable shell globbing so that special meaning/care
232# may be used with variables/arguments to custom functions. That would be:
233# @CODE
234# eshopts_push -s noglob
235# for x in ${foo} ; do
236# if ...some check... ; then
237# eshopts_pop

121# This function is for bulk patching, or in theory for just one 353# @FUNCTION: epatch
122# or two patches. 354# @USAGE: [options] [patches] [dirs of patches]
355# @DESCRIPTION:
356# epatch is designed to greatly simplify the application of patches. It can
357# process patch files directly, or directories of patches. The patches may be
358# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
359# the -p option as epatch will automatically attempt -p0 to -p4 until things
360# apply successfully.
123# 361#
124# It should work with .bz2, .gz, .zip and plain text patches. 362# If you do not specify any patches/dirs, then epatch will default to the
125# Currently all patches should be the same format. 363# directory specified by EPATCH_SOURCE.
126# 364#
127# You do not have to specify '-p' option to patch, as it will 365# Any options specified that start with a dash will be passed down to patch
128# try with -p0 to -p5 until it succeed, or fail at -p5. 366# for this specific invocation. As soon as an arg w/out a dash is found, then
367# arg processing stops.
129# 368#
130# Above EPATCH_* variables can be used to control various defaults, 369# When processing directories, epatch will apply all patches that match:
131# bug they should be left as is to ensure an ebuild can rely on 370# @CODE
132# them for. 371# if ${EPATCH_FORCE} != "yes"
133#
134# Patches are applied in current directory.
135#
136# Bulk Patches should preferibly have the form of:
137#
138# ??_${ARCH}_foo.${EPATCH_SUFFIX} 372# ??_${ARCH}_foo.${EPATCH_SUFFIX}
373# else
374# *.${EPATCH_SUFFIX}
375# @CODE
376# The leading ?? are typically numbers used to force consistent patch ordering.
377# The arch field is used to apply patches only for the host architecture with
378# the special value of "all" means apply for everyone. Note that using values
379# other than "all" is highly discouraged -- you should apply patches all the
380# time and let architecture details be detected at configure/compile time.
139# 381#
140# For example: 382# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
383# for patches to apply.
141# 384#
142# 01_all_misc-fix.patch.bz2 385# Refer to the other EPATCH_xxx variables for more customization of behavior.
143# 02_sparc_another-fix.patch.bz2
144#
145# This ensures that there are a set order, and you can have ARCH
146# specific patches.
147#
148# If you however give an argument to epatch(), it will treat it as a
149# single patch that need to be applied if its a file. If on the other
150# hand its a directory, it will set EPATCH_SOURCE to this.

663# of these three directories to exist will be the one to use, ignoring
664# any more general directories which might exist as well. They must end
665# in ".patch" to be applied.
666#
667# User patches are intended for quick testing of patches without ebuild
668# modifications, as well as for permanent customizations a user might
669# desire. Obviously, there can be no official support for arbitrarily
670# patched ebuilds. So whenever a build log in a bug report mentions that
671# user patches were applied, the user should be asked to reproduce the
672# problem without these.
673#
674# Not all ebuilds do call this function, so placing patches in the
675# stated directory might or might not work, depending on the package and
676# the eclasses it inherits and uses. It is safe to call the function
677# repeatedly, so it is always possible to add a call at the ebuild
678# level. The first call is the time when the patches will be
679# applied.
680#
681# Ideally, this function should be called after gentoo-specific patches
682# have been applied, so that their code can be modified as well, but

902# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek

904# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin

1684# listed in it are installed as HTML docs (using dohtml).
