Oct 6, 2008 · GCC or G++ just choose a different front-end with different default options. In a nutshell: if you use g++ the frontend will tell the linker that you may want to link with the C++ standard libraries. The gcc frontend won't do that (also it could link with them if you pass the right command line options).

Aug 2, 2023 · GCC stands for "GNU Compiler Collection" and is a piece of GNU software that includes a compiler with frontends for multiple languages: The standard compiler releases since 4.6 include front ends for C (gcc), C++ (g++), Objective-C, Objective-C++, Fortran (gfortran), Java (gcj), Ada (GNAT), and Go (gccgo).

gcc is the driver binary for the GNU compiler collection. It can compile C, C++, and possibly other languages; it determines the language by the file extension. g++ is a driver binary like gcc, but with a few special options set for compiling C++. Notably (in my experience), g++ will link libstdc++ by default, while gcc won't.

Apr 6, 2015 · Your question is refering to gcc linker (or simply ld). Description can be found in in gcc's Options for Linking or ld's Command Line Options. From the documentation you get-larchive: Add archive file archive to the list of files to link. ld will search its path-list for occurrences of libarchive.a for every archive specified.

Nov 5, 2018 · Is there a way to get gcc to output the available -march=arch options? I'm getting build errors (tried -march=x86_64) and I don't know what my options are. The compiler I'm using is a proprietary wrapper around gcc that doesn't seem to like -march=skylake. The flags should be the same so I assume whatever options I'd send to gcc to dump ...

I'm distributing a C++ program with a makefile for the Unix version, and I'm wondering what compiler options I should use to get the fastest possible code (it falls into the category of programs that can use all the computing power they can get and still come back for more), given that I don't know in advance what hardware, operating system or ...
