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 generate linker scripts in /usr/lib for dynamic 12# are not required in all ebuilds but enough utilize them to have a common
20# libs in /lib. This is to fix linking problems when you have 13# home rather than having multiple ebuilds implementing the same thing.
21# the .so in /lib, and the .a in /usr/lib. What happens is that
22# in some cases when linking dynamic, the .a in /usr/lib is used
23# instead of the .so in /lib due to gcc/libtool tweaking ld's
24# library search path. This cause many builds to fail.
25# See bug #4411 for more info.

27# To use, simply call: 15# Due to the nature of this eclass, some functions may have maintainers
28# 16# different from the overall eclass!

31# Note that you should in general use the unversioned name of
32# the library, as ldconfig should usually update it correctly

149# @FUNCTION: eshopts_push
150# @USAGE: [options to `set` or `shopt`]
151# @DESCRIPTION:
152# Often times code will want to enable a shell option to change code behavior.
153# Since changing shell options can easily break other pieces of code (which
154# assume the default state), eshopts_push is used to (1) push the current shell
155# options onto a stack and (2) pass the specified arguments to set.
156#
157# If the first argument is '-s' or '-u', we assume you want to call `shopt`
158# rather than `set` as there are some options only available via that.
159#
160# A common example is to disable shell globbing so that special meaning/care
161# may be used with variables/arguments to custom functions. That would be:
162# @CODE
163# eshopts_push -s noglob
164# for x in ${foo} ; do
165# if ...some check... ; then
166# eshopts_pop

111# This function is for bulk patching, or in theory for just one 282# @FUNCTION: epatch
112# or two patches. 283# @USAGE: [options] [patches] [dirs of patches]
284# @DESCRIPTION:
285# epatch is designed to greatly simplify the application of patches. It can
286# process patch files directly, or directories of patches. The patches may be
287# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
288# the -p option as epatch will automatically attempt -p0 to -p5 until things
289# apply successfully.
113# 290#
114# It should work with .bz2, .gz, .zip and plain text patches. 291# If you do not specify any patches/dirs, then epatch will default to the
115# Currently all patches should be the same format. 292# directory specified by EPATCH_SOURCE.
116# 293#
117# You do not have to specify '-p' option to patch, as it will 294# Any options specified that start with a dash will be passed down to patch
118# try with -p0 to -p5 until it succeed, or fail at -p5. 295# for this specific invocation. As soon as an arg w/out a dash is found, then
296# arg processing stops.
119# 297#
120# Above EPATCH_* variables can be used to control various defaults, 298# When processing directories, epatch will apply all patches that match:
121# bug they should be left as is to ensure an ebuild can rely on 299# @CODE
122# them for. 300# if ${EPATCH_FORCE} != "yes"
123#
124# Patches are applied in current directory.
125#
126# Bulk Patches should preferibly have the form of:
127#
128# ??_${ARCH}_foo.${EPATCH_SUFFIX} 301# ??_${ARCH}_foo.${EPATCH_SUFFIX}
302# else
303# *.${EPATCH_SUFFIX}
304# @CODE
305# The leading ?? are typically numbers used to force consistent patch ordering.
306# The arch field is used to apply patches only for the host architecture with
307# the special value of "all" means apply for everyone. Note that using values
308# other than "all" is highly discouraged -- you should apply patches all the
309# time and let architecture details be detected at configure/compile time.
129# 310#
130# For example: 311# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
312# for patches to apply.
131# 313#
132# 01_all_misc-fix.patch.bz2 314# Refer to the other EPATCH_xxx variables for more customization of behavior.
133# 02_sparc_another-fix.patch.bz2
134#
135# This ensures that there are a set order, and you can have ARCH
136# specific patches.
137#
138# If you however give an argument to epatch(), it will treat it as a
139# single patch that need to be applied if its a file. If on the other
140# hand its a directory, it will set EPATCH_SOURCE to this.

589# of these three directories to exist will be the one to use, ignoring
590# any more general directories which might exist as well. They must end
591# in ".patch" to be applied.
592#
593# User patches are intended for quick testing of patches without ebuild
594# modifications, as well as for permanent customizations a user might
595# desire. Obviously, there can be no official support for arbitrarily
596# patched ebuilds. So whenever a build log in a bug report mentions that
597# user patches were applied, the user should be asked to reproduce the
598# problem without these.
599#
600# Not all ebuilds do call this function, so placing patches in the
601# stated directory might or might not work, depending on the package and
602# the eclasses it inherits and uses. It is safe to call the function
603# repeatedly, so it is always possible to add a call at the ebuild
604# level. The first call is the time when the patches will be
605# applied.
606#
607# Ideally, this function should be called after gentoo-specific patches
608# have been applied, so that their code can be modified as well, but

889# basically look for the first lseek command (we do the strings/grep because
890# sometimes the function call is _llseek or something) and steal the 2nd
891# parameter. here is an example:
892# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
893# lseek
894# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin

1209#
1210# A temporary hack until portage properly supports DEPENDing on USE
1211# flags being enabled in packages. This will check to see if the specified
1212# DEPEND atom was built with the specified list of USE flags. The
1213# --missing option controls the behavior if called on a package that does
1214# not actually support the defined USE flags (aka listed in IUSE).
1215# The default is to abort (call die). The -a and -o flags control
1216# the requirements of the USE flags. They correspond to "and" and "or"
1217# logic. So the -a flag means all listed USE flags must be enabled
1218# while the -o flag means at least one of the listed IUSE flags must be
1219# enabled. The --hidden option is really for internal use only as it
1220# means the USE flag we're checking is hidden expanded, so it won't be found
1221# in IUSE like normal USE flags.
