Self made compiler learning 1: use of CB compiler

Cb stay C The foundation of the language has been simplified , And add some new features , Thus, the production process of the compiler is simplified , First of all Cb Compiler installation , The use system is Ubuntu 16,Cb Compiler 64 A version of the git The website is ： hGitHub - leungwensen/cbc-ubuntu-64bit: Cb (C flat) compiler. Cb is simplified C.s

First , Install dependency library ：

apt-get update && apt-get install -y \
        gcc-multilib g++-multilib libc6-i386 lib32ncurses5 lib32stdc++6 \
        openjdk-8-jre \
        git

Download and install cbc：

git clone https://github.com/leungwensen/cbc-ubuntu-64bit.git
cd cbc-ubuntu-64bit && ./install.sh

compiler cbc Default installed in /usr/local/cbc/bin, Note that it is added to the environment variable PATH.

Create the first program file test_cb.cb：

import stdio;

int
main(int argc, char **argv)
{
printf("Hello World!\n");
return 0;
}

Execute compilation instructions （ Be careful 64 Bit system needs to be compatible 32 position ）：

 cbc -Wa,"--32" -Wl,"-melf_i386" cbc_test.cb

After the compilation and execution are successful, there will be the following files in the folder ：

They correspond to each other compile Generated Assembly language files ：cbc_test.s, assembly Generated Target file cbc_test.o, as well as link Generated Executable file cbc_test.
