Can't be too hard to use it for +# correct static linkage... well it took more than two weeks to hopefully identify all +# problems / edge cases. Now I can appreciate the usage bin/lo-all-static-libs even more. +# +# This code moved a few times to the various gbuild / make phases: Makefile / module +# setup (in use_(libraries|externals)), post parsing (like now), make "dependency" tree +# processing. It currently looks like this is the only working option. +# +# For static linking, we must collect all depending libraries, externals and statics to +# be available at link time. And Libraries and externals can use each other. This could +# be done "in-line", while make processes the dependency tree and would have the correct +# order, so no separate tree-walking would be needed. +# It can't be done while reading / processing the modules, as this happens in no order, so +# depending modules will be missing. +# +# Then there is the (gbuild new) concept of plugin libraries. These depend on some loader +# libraries, like vcl and vclplug_* or gie. For a shared library build, these plugins are +# just dlopen'ed, but for a static build, any linked binary must also link the plugins, which +# turns plugins + loaders into a dependency cycle. The implemented solution is to just add +# plugins to executables, if these depend on a loader library. This results in the additional +# rule: nothing non-plugin is allowed to depend on a plugins (see gb_Library_set_plugin_for). +# +# And we can't add these dependencies while make is already processing the Executables, +# because these contain additional eval'ed targets, which we can't create in make recipes. +# This is especially true for externals (see gb_LinkTarget__use_* in RepositoryExternal.mk). +# We also can't add all plugins to all executables, as we have multiple helper +# binaries, which are needed early and don't depend on plugins. +# +# So the only option left seems to be to walk the dependency tree ourself and expand all +# the libraries and externals and then add the plugins to the executables. Statics are +# handled after that, since these won't need extra dependencies not already known. +# It's a bit fragile in theory, as you can add "gbuild-undetectable" dependencies to any +# target in the modules, which would need some manual adjustment, but currently that +# doesn't seem to happen in any breaking way and it works to link multiple Executable +# with large and small expanded dependency lists. +# +# Then there is the special static "components" library, which simply depends on all build +# components. In theory these could be limited per-module (Writer, Calc, etc.), but currently +# this is not implemented and instead solenv/bin/native-code.py is used, so actually +# everything is build and "cleaned up" at link time, which is especially expensive for WASM. +# That library is currently just used for Emscripten, but could be used generally for +# static builds. +# +# There is already a lot of $(info ...) protected by the already mentioned $(gb_DEBUG_STATIC). + +ifeq ($(gb_FULLDEPS),$(true)) +ifeq (,$(gb_PARTIAL_BUILD)) + +$(foreach lib,$(gb_Library_KNOWNLIBS),$(if $(call gb_Library__get_component,$(lib)), \ + $(eval $(call gb_Library_use_libraries,components,$(lib))))) + +define gb_LinkTarget__add_x_template + +# call gb_LinkTarget__add_$(1),linktarget,objects +define gb_LinkTarget__add_$(1) +$$(foreach item,$$(2),$$(if $$(filter $$(item),GBUILD_TOUCHED $$(call gb_LinkTarget__get_all_$(1),$$(1))),, + $$(if $(gb_DEBUG_STATIC),$$(info $$(call gb_LinkTarget__get_all_$(1)_var,$$(call gb_LinkTarget__get_workdir_linktargetname,$$(1))) += $$(item))) + $$(eval $$(call gb_LinkTarget__get_all_$(1)_var,$$(call gb_LinkTarget__get_workdir_linktargetname,$$(1))) += $$(item)) +)) +endef + +endef #
