The problem here is that the CPDB support for the GTK print dialog was created in an early stage of the formation of the second-generation API of CPDB. Some functions still had an instance name parameter and this parameter got dropped later. So in the GTK code the calls have to get corrected, removing the instance name.
The patch should be proposed as merge request to GTK upstream and applied as distro patch for Plucky. Here is the commit in CPDB which did the change of dropping the instance name parameter: https://github.com/OpenPrinting/cpdb- libs/commit/fb2686ba8f2fc60dc95ae0e2421e386922bf232e So it is just removing the instance name of the calls of these functions. ** Changed in: cpdb-libs (Ubuntu) Status: Triaged => Invalid -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gtk4 in Ubuntu. https://bugs.launchpad.net/bugs/2100307 Title: gtk4 fails to build with cpdb-libs 2.0~b7 Status in cpdb-libs package in Ubuntu: Invalid Status in fragments package in Ubuntu: New Status in gtk4 package in Ubuntu: Triaged Status in warp package in Ubuntu: New Bug description: gtk4 fails to build after the upload of cpdb-libs 2.0~b7-0ubuntu1 Full build log ============= https://launchpad.net/~jbicha/+archive/ubuntu/arch/+build/30363110 Build log excerpt ================= ../../../modules/printbackends/gtkprintbackendcpdb.c: In function ‘gtk_print_backend_cpdb_init’: ../../../modules/printbackends/gtkprintbackendcpdb.c:291:55: error: passing argument 1 of ‘cpdbGetNewFrontendObj’ from incompatible pointer type [-Wincompatible-pointer-types] 291 | backend_cpdb->frontend_obj = cpdbGetNewFrontendObj (instance_name, | ^~~~~~~~~~~~~ | | | char * In file included from /usr/include/cpdb/frontend.h:4, from ../../../modules/printbackends/gtkprintbackendcpdb.c:22: /usr/include/cpdb/cpdb-frontend.h:102:66: note: expected ‘cpdb_printer_callback’ {aka ‘void (*)(struct cpdb_frontend_obj_s *, struct cpdb_printer_obj_s *, enum cpdb_printer_update_e)’} but argument is of type ‘char *’ 102 | cpdb_frontend_obj_t *cpdbGetNewFrontendObj(cpdb_printer_callback printer_cb); | ~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~ ../../../modules/printbackends/gtkprintbackendcpdb.c:291:32: error: too many arguments to function ‘cpdbGetNewFrontendObj’ 291 | backend_cpdb->frontend_obj = cpdbGetNewFrontendObj (instance_name, | ^~~~~~~~~~~~~~~~~~~~~ /usr/include/cpdb/cpdb-frontend.h:102:22: note: declared here 102 | cpdb_frontend_obj_t *cpdbGetNewFrontendObj(cpdb_printer_callback printer_cb); | ^~~~~~~~~~~~~~~~~~~~~ Other Info ========= I believe this needs to be fixed in cpdb-libs but I'm adding other affected packages to show on the excuses report. Some packages are indirectly affected because they depend on gtk4 being updated but we can't update gtk4.
