Papež se také poprvé omluvil za roli, kterou Vatikán sehrál při legitimizaci otroctví, a za to, že jej po staletí neodsoudil.
Český telekomunikační úřad zveřejnil Výroční zprávu za rok 2025 (pdf), která shrnuje jeho hlavní aktivity v oblasti regulace elektronických komunikací, poštovních služeb, digitálních služeb a přípravy na dohled nad umělou inteligencí. Součástí zprávy jsou také data o vývoji trhu, včetně pokračujícího růstu spotřeby mobilních dat a rozšiřování sítí nové generace. Celkový objem přenesených mobilních dat dosáhl v roce 2025 přibližně

g++. _GLIBCXX_NODISCARD je nejspíš atribut [[nodiscard]], _GLIBCXX20_CONSTEXPR je constexpr. Našel jsem třeba nějaký náhodný zdroják, kde (CTRL+F _GLIBCXX20_CONSTEXPR):
#ifndef _GLIBCXX20_CONSTEXPR # if __cplusplus > 201703L # define _GLIBCXX20_CONSTEXPR constexprTakže je otázka, proč ty tam tyhle definice nemáš (i když jinde se tam používají) a kompilátor tomu nerozumí. Zkus
g++ prostě přeinstalovat (a případně předtím ještě promazat ty hlavičkové soubory).
Diky moc, toto nakoniec nepriamo pomohlo.
Preinstalovat g++ nepomohlo - ale mas dobry postreh a vsimol si si, ze mam premiesane hlavickove subory. Tak som odinstaloval libgcc-8-dev a libgcc-7-dev (a vsetko, co na tom zaviselo) a kompilacia uz ide.
