I want to compile a C++ program in Arch Linux, but there's no "g++" package as there is in Ubuntu repositories for example.

Using -x too won't work. like this:

gcc -x c++ -o myprog myprog.cpp

gcc is both a C and C++ compiler.
It will look at the file's extension and process accordingly.
g++ is only a wrapper that calls gcc
g++ is installed with the gcc package in Arch

gcc file.C # uppercase .C (or .cpp) will process as C++ 
gcc file.c # lowercase .c will process as C
  • Though I have gcc on my Arch, there's no g++, and though my file is prog.cpp and I also use -x c++ I should tell you it only works in case I also add -lstdc++, which correctly compiles. Do you suggest this method? (gcc -x c++ -o myprog -lstdc++ myprog.cpp) – Haix64 Mar 21 '12 at 12:19
  • if you use std c++ in your code then yes, you need to link (-lstdc++) with the std c++ library. I've installed gcc on my arch and g++ is present. It should be in /usr/bin, I don't believe the -x c++ is needed if file extension is .cpp, gcc should select on that – bsd Mar 21 '12 at 13:13

    g++ should be part of the gcc package. Have you tried reinstalling gcc? – Craig Mar 21 '12 at 16:56

  • You gotta be right Craig. I had not installed the gcc manually, since I thought having access to gcc should mean that I've got the whole package on system, but pacman shows me there's 18MB to download for the gcc package. I haven't done it yet but I'm sure it works as soon as I do it. Thanks for your helps, Craig and bdowning. – Haix64 Mar 23 '12 at 14:23
