  • ARM Code Development in Windows
    ARM Code Development in Windows By: Ali Nuhi This guide will describe how to develop code to be run on an embedded Linux system using an ARM processor (specifically the OMAP3530). Environment The Cygwin bash shell will be the environment used for code development. Download it from the below link. http://cygwin.com/install.html READ THE SITE. Download setup.exe and choose the packages you want to install. Some helpful packages to download are: -gcc4-core,g++ etc. (for c and c++ compiling of normal programs) -git core files and completion (version control system) -wget (utility to download files from the internet via HTTP and FTP) -VIM (text editor) -Xemacs (another text editor, better than vim) -nano (simple command line text editor) If you still use windows notepad for writing code please atleast upgrade to notepad++. Toolchain We will be compiling and creating files using CodeSourcery g++ lite toolchains. This is a modified version of GCC which will create files specifically for ARM target systems. Download this at: http://www.codesourcery.com/sgpp/lite/arm/portal/release1803 Download the Windows installer and execute. You can let it install as is unless you have some other install scheme on your computer. I highly recommend reading the getting started pdf that comes with CodeSourcery. Once it’s fully installed open up Cygwin and execute the below lines. $ export CYGPATH=cygpath $ export CYGPATH=c:/cygwin/bin/cygpath If you installed Cygwin to another directory then you must edit the second line. To use the compiler type the following and hit tab twice to see all of the possible options you have.

For the human brain, sequences like -> , <= or := are single logical tokens, even if they take two or three characters on the screen. Your eye spends a non-zero amount of energy to scan, parse and join multiple characters into a single logical one. Ideally, all programming languages should be designed with full-fledged Unicode symbols for operators, but that’s not the case yet. Solution Download v1.203 · How to install · News & updates Fira Code is an extension of the Fira Mono font containing a set of ligatures for common programming multi-character combinations.

  • A Brief Introduction to the Use of Shell Variables
    A Brief Introduction to the Use of Shell Variables Norman Matloff July 25, 2001 Contents 1 Two Popular Shells: tcsh and bash 1.1 Overview There are many different shells available for Unix systems. Here we focus on two of the most popular ones, tcsh and bash. Other shells tend to be very similar to one or both of these. Your Unix account has a preset login shell for you, typically tcsh in academic settings and bash in Linux. When you log in, a shell of the given type is automatically started for you. (This can be seen in the file /etc/passwd.) If you wish to temporarily run a different shell, just type its name. If you wish to change your login shell, run the chsh command. 1.2 Command Commonality Among Shells Most of what people tend to think of as “basic Unix commands” are actually shell commands which are common to almost all of the shells. So for example you could type cd /abc/def to change to the directory /abc/def in either tcsh or bash.1 2 Shell Variables 2.1 Introduction to Shell Variable Syntax The tcsh shell uses “set” and = for the assignment operation. For example, 1Technically speaking, the “change directory” command for Unix itself is chdir(), a function which must be called from a program. A shell is a program, and when for example you issue the cd command to a shell, that program in turn calls chdir(). 1 set x = 3 would assign the value 3 to the shell variable x.

For a long time now the industry has been moving from Unix workstations to Windows/Intel desktop machines. The wintel price/performance has been fantastic, the IT guys are happier, and all of that productivity software that you spend so much time with runs in the same spot. We have been happy with a stable and known environment. However, accepting the fact that unless you work for a big company that can buy some Unix servers, you just don’t have an easy way to get some extra horsepower other then getting a new box. Then along comes this Finnish guy that may or may not have been named after Lucy’s little brother. With not much of a life and a very large brain, he popped out the majority of a complete and free version of Unix that anyone can use, breaking the stranglehold of (expensive) proprietary Unix OS’s that ran on (expensive) proprietary hardware.

    Shell Using the command line Orna Agmon ladypine at vipe.technion.ac.il Haifux Shell – p. 1/55 TOC Various shells Customizing the shell getting help and information Combining simple and useful commands output redirection lists of commands job control environment variables Remote shell textual editors textual clients references Shell – p. 2/55 What is the shell? The shell is the wrapper around the system: a communication means between the user and the system The shell is the manner in which the user can interact with the system through the terminal. The shell is also a script interpreter. The simplest script is a bunch of shell commands. Shell scripts are used in order to boot the system. The user can also write and execute shell scripts. Shell – p. 3/55 Shell - which shell? There are several kinds of shells. For example, bash (Bourne Again Shell), csh, tcsh, zsh, ksh (Korn Shell). The most important shell is bash, since it is available on almost every free Unix system. The Linux system scripts use bash. The default shell for the user is set in the /etc/passwd file. Here is a line out of this file for example: dana:x:500:500:Dana,,,:/home/dana:/bin/bash This line means that user dana uses bash (located on the system at /bin/bash) as her default shell. Shell – p. 4/55 Starting to work in another shell If Dana wishes to temporarily use another shell, she can simply call this shell from the command line: [dana@granada ˜]$ bash dana@granada:˜$ #In bash now dana@granada:˜$ exit [dana@granada ˜]$ bash dana@granada:˜$ #In bash now, going to hit ctrl D dana@granada:˜$ exit [dana@granada ˜]$ #In original shell now Shell – p.
