51# @ECLASS-VARIABLE: RUBY_S
52# @DEFAULT_UNSET
53# @DESCRIPTION:
54# If defined this variable determines the source directory name after
55# unpacking. This defaults to the name of the package. Note that this
56# variable supports a wildcard mechanism to help with github tarballs
57# that contain the commit hash as part of the directory name.
58
59# @ECLASS-VARIABLE: RUBY_QA_ALLOWED_LIBS
60# @DEFAULT_UNSET
61# @DESCRIPTION:
62# If defined this variable contains a whitelist of shared objects that
63# are allowed to exist even if they don't link to libruby. This avoids
64# the QA check that makes this mandatory. This is most likely not what
65# you are looking for if you get the related "Missing links" QA warning,
66# since the proper fix is almost always to make sure the shared object
67# is linked against libruby. There are cases were this is not the case
68# and the shared object is generic code to be used in some other way
69# (e.g. selenium's firefox driver extension). When set this argument is
70# passed to "grep -E" to remove reporting of these shared objects.
