Witam.
Napisałem sobie ostatnio prosty programik w c++, próbowałem go skompilować za pomocą gcc i napotkał mnie bardzo dziwny komunikat. Sam kod jest w 100% poprawny, więc pytanie brzmi czy to chwilowy błąd gcc (SID) czy brakuje czegoś kompilatorowi. Stawiam raczej na to drugie jednak nie mam pojęcia czego może brakować. Ten sam komunikat pojawia się nawet podczas próby kompilacji programiku typu Hello World

Oto co pokazuje gcc:

Z góry dziękuję za jakąkolwiek pomoc, pozdrawiam.

skompiluj to g++
albo dopisz opcje, ze chodzi ci o c++ (gcc -x jezyk czy jakos tak) innaczej nie dolacza biblioteki standardowej c++ i linker nie ma jak jej zlinkowac

Moim zdaniem masz źle skompilowany program powinno być

g++ droga.cpp -o droga

a następnie uruchamiasz go

./droga

w terminalu
