Things to remember when compiling/linking C/C++ software

by Angel Leon. March 17, 2015; August 29, 2019.

Include Paths

On the compilation phase, you will usually need to specify the different include paths so that the interfaces (.h, .hpp) which define structs, classes, constans, and functions can be found.

With gcc and llvm include paths are passed with -I/path/to/includes, you can pass as many -I as you need.

In Windows, cl.exe takes include paths with the following syntax: /I"c:\path\to\includes\ you can also pass as many as you need.

Introduction

C-a == Ctrl-a
M-a == Alt-a

General

:q        close
:w        write/saves
:wa[!]    write/save all windows [force]
:wq       write/save and close

Install Redis

wget http://download.redis.io/redis-stable.tar.gz

tar xvzf redis-stable.tar.gz cd redis-stable

make

make install
