Dotaz: Rozbite G++

[LK]

Nazdar, na PC mam rozbite g++ - tusite, kde moze byt problem? Najmensi reproducer:

$ cat /tmp/a.cpp 
#include <string>

int main() {
  return 0;
}

Vystup:

$ g++ /tmp/a.cpp

Nemas rozbite. Ale ak chces includovat a la string.h z C-ka, tak mas includovat cstring.

[hm]

Debiane děláš si prdel???????????????????????

[z_sk]

Nemas to ok:

$ cat a.cpp
#include <string>

int main() {
	  return 0;
}
$
$ g++ a.cpp
$ g++ --version
g++ (Debian 9.3.0-16) 9.3.0

Nainstaluj si balicek g++-10, a robi to aj v g++ desiatke?

Připadá mi to jako by se ti nějak pomíchaly hlavičkové soubory s jinou verzí 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 constexpr

Takže 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.
