The error is in an include file shipped with poppler, but poppler itself doesn't FTBFS...
Looking more closely, I see poppler is built with -std=c++20, and according to [1] the ends_with/starts_with are defined in c++20. But dia is built with -std=gnu17 (defined in [2]). That change in [2] was done via commit [3]: From 7093a1ad332c8efd91c81d6030ced5a86ab69309 Mon Sep 17 00:00:00 2001 From: Zander Brown <[email protected]> Date: Tue, 8 Aug 2023 05:29:53 +0100 Subject: [PATCH] build: set c++ standard Close: https://gitlab.gnome.org/GNOME/dia/-/merge_requests/96 --- meson.build | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/meson.build b/meson.build index cd988500c..0d3e4d282 100644 --- a/meson.build +++ b/meson.build @@ -2,7 +2,12 @@ project('dia', ['c', 'cpp'], version: '0.97.3', # This is the base version, git suffix gets added using vcs_tag(). meson_version: '>= 0.58', - default_options: ['warning_level=1'] + default_options: [ + 'warning_level=1', + 'buildtype=debugoptimized', + 'c_std=gnu17', + 'cpp_std=gnu++17', + ], ) cc = meson.get_compiler('c') -- GitLab The last successful build of dia was at [4], on 2024-04-08, and it was already using -std=gnu17[5], and I don't even see warnings in the logs.
