yes... before I revised it in 2017 - https://invisible-island.net/ncurses/tack/CHANGES.html#t20170318 tack used internal entrypoints of ncurses, which I eliminated. Version 1.07 and earlier do that, and could be built within ncurses' source-tree (to get at those headers). The current versions of tack use only term_entry.h, which is needed to provide its editable-terminfo feature. While repology lists some older versions, I don't see a need to continue the support for those. https://repology.org/project/tack/versions Those headers would be needed if there were some application using "ticlib", but that doesn't build if we have ncurses+tinfo, so there aren't any users. > Supplying an empty ncurses_cfg.h file might be sufficient for your > purposes, but I don't know what these are. It would supply values for the #if statements: tic.h #if NCURSES_EXT_COLORS && HAVE_INIT_EXTENDED_COLOR #if HAVE_LONG_FILE_NAMES #ifdef TRACE #ifndef TERMINFO #ifdef NCURSES_INTERNALS #if BROKEN_LINKER nc_tparm.h #ifndef NC_TPARM_included #ifndef TPARM_ARG #ifdef NCURSES_TPARM_ARG #if NCURSES_TPARM_VARARGS #ifdef NCURSES_INTERNALS term_entry.h has a few (and tack's configure-script sets them as needed): #ifdef NCURSES_INTERNALS #if NCURSES_USE_DATABASE #if NCURSES_USE_TERMCAP #if NCURSES_XNAMES -- Thomas E.
