2026.9.29.4: a program shipped through artifacts links with its own closure's line, and ${mcpp.bin_dir} is the declaring member's product directory, in a workspace plan - #741
Merged
Conversation
…losure's line in a workspace plan The validation project's post-release build of 2026.9.29.3 stopped at the link of obj/gpp_updater/Updater.exe with undefined references to Qt and bit7z symbols: the libraries are stated by the updater package's build program, and the program was linked with the plan's line, which pools the dependencies' link flags and not a member's. - In a workspace plan each program shipped through artifacts has a link group of its own closure (LinkGroup::linkOnly): the closure's link line and runtime contract, and no placement, since the members that ship the program place it and its runtime files. - e2e 838 states it with a library the helper's build program links (mcpp::link_lib); it fails on 2026.9.29.3 with "undefined reference" at obj/helper/helper and passes here. - Version 2026.9.29.4; design document section 17.1.
…res is that member's product directory
The validation project's cross-verification against this pull request stopped
at mcpp pack: its build script stages ${mcpp.bin_dir}/<target>.pdb, and the
placeholder expanded to the plan's bin/, where a member's binaries are not.
e2e 838 A4 states it; docs/30 (both languages) state the expansion.

…9.29.4 (#489) 2026.9.29.4 (mcpp-community/mcpp#741) links a program a workspace member ships through artifacts with its own closure's line and expands ${mcpp.bin_dir} in an action a member's build program declares to that member's product directory. It changes no descriptor grammar; min_mcpp is unchanged. The full sweep with 2026.9.29.4 (run 36548558591) passed on every platform.
