New script for rpm Provides/Requires, replacement for rpm built-in ocaml(NAME)=hash, which covers bytecode and interfaces Now it covers also native code via ocamlx(NAME)=HASH (bsc#1154874) - Update the filelist generator Use awk to match directories in ocamls built-in ld.conf C stublibs in default locations do not need a ld.so.conf entry Remaining ld.so.conf files for stublibs go to the devel package - Disable debug in ocamlfind() Provides/Requires generator Update META parser to handle multiline statements and ppx - Provide a ocaml_standard_library macro - Explicitly preserve debuginfo in .cmxs, already enforced by dune OBS-URL: https://build.opensuse.org/package/show/devel:languages:ocaml/ocaml-rpm-macros?expand=0&rev=35

# This is a helper for rpm which collects 'Provides' and 'Requires' information from OCaml files.
|
|
# It reads a list of filenames from STDIN.
|
|
# It expects as argument either '--provides|-P' or '--requires|-R'.
|
|
# Additional optional arguments are:
|
|
# -f "ocamlobjinfo command"
|
|
# -c # ignored, recognized just for compat reasons
|
|
# -i NAME # omit the Requires/Provides for this bytecode unit name
|
|
# -x NAME # omit the Requires/Provides for this native unit name
|
|
#
|
|
# OCaml object files contain either bytecode or native code.
|
|
# Each bytecode variant provides a certain interface, which is represented by a hash.
|
|
# Each native variant provides a certain interface and a certain implementation, which are represented by hashes.
|
|
# Each variant may also require a certain interface and/or implementation provided by other files.
|
|
# The details for each file can be inspected with 'ocamlobjinfo'.
|
|
#
|
|
# Each file contains at least one module.
|
|
# Information about each module follows after a line starting with "Name:" or "Unit name:":
|
|
#
|
|
# cma/cmi/cmo (bytecode):
|
|
# Unit name: NAME
|
|
# Interfaces imported:
|
|
# HASH NAME
|
|
# HASH NAME_FROM_OTHER_MODULE
|
|
#
|
|
# cmx/cmxa/cmxs (native):
|
|
# Name: NAME
|
|
# CRC of implementation: HASH
|
|
# Interfaces imported:
|
|
# HASH NAME
|
|
# HASH NAME_FROM_OTHER_MODULE
|
|
# Implementations imported:
|
|
# HASH NAME_FROM_OTHER_MODULE
|
|
#
|
|
# The hash may contain just '-', in which case it is ignored.
|
|
#
|
|
# Output:
|
|
# ocaml(NAME) = HASH # for interfaces (bytecode and native)
|
|
# ocamlx(NAME) = HASH # for implementations (native)
