Compiling with gcc is okay but g++ is not [on hold]

Originally gcc -o main main.cpp produce same error like



main.cpp:10:20: fatal error: iostream: No such file or directory

#include <iostream>


But after install gcc with brew (brew install gcc)
and link (brew link gcc), the version of gcc is renew (4.8.1 -> 8.2.0)



So compiling with gcc(gcc -o main main.cpp) is okay but
g++ -o main main.cpp still produce same error message.



What should I do for g++ compile?






macos gcc g++

    Have you added using namespace std; after the #include?

  • Of course.... the code is very very simple and can be compiled with gcc

    The iostream file is provided by the corresponding libstdc++ package. Ensure that both g++ and libstdc++ are installed and latest versions. If that doesn't help, show us your code.

  • I think it's not problem of source code. Actually, I have deleted some files and directories to upgrade gcc and g++ version but I didn't do well.... So , during that course maybe my g++ compiler has gone

Can an atomic nucleus contain both particles and antiparticles? [duplicate]
