CppFX - The CPP (C++) Programming Language FX

[cpp] Clang C++ on FreeBSD

FreeBSD is a complete operating system. It officially supports c++ programming language. Clang c++ compiler has been living in FreeBSD base system for many years. You can use clang to compile c++ code without installing any additional software on FreeBSD.

$ which clang
/usr/bin/clang
$ which clang++
/usr/bin/clang++

And FreeBSD supplies you two basic screen editors, vi/nvi and ee to write any code, which doesn't need to install any additional software too. And there are so many line editors usable on the base system.

$ which vi
/usr/bin/vi
$ which nvi
/usr/bin/nvi

However, if you want a beautify editor you can install vim and so on.

pkg install vim-console

There are some other clang(llvm) c++ compiler distributions available from ports and pkg, you can install them for your special case.

$ pkg search llvm | awk '/^llvm/'
llvm-90                        Meta-port for the default version of the LLVM Toolchain
llvm-cheri-11.0.d20201209      LLVM and Clang with support for the CHERI architecture
llvm-devel-13.0.d20210408_1    LLVM and Clang
llvm-devel-lite-13.0.d20210408_1 LLVM and Clang
llvm10-10.0.1_5                LLVM and Clang
llvm11-11.0.1                  LLVM and Clang
llvm12-12.0.0.r4               LLVM and Clang
llvm70-7.0.1_5                 LLVM and Clang
llvm80-8.0.1_4                 LLVM and Clang
llvm90-9.0.1_3                 LLVM and Clang

Install llvm-devel:

pkg install llvm-devel

And compile your c++ code with the compiler:

# Use latest c++ compiler
clang++-devel your-code.cpp

# Use stable c++ compiler
clang++ your-code.cpp

And many clang/llvm underlying toolchains are avaible on FreeBSD, such as lld, lldb, etc.:
