System Programming - LAB 1 Programming Environments

General information Niccolo` Battezzati web site: (teaching section) LABs schedule: WEDNESDAY 8: :30 (LABINF)

Windows Programming MS Visual Studio 2005 IDE for Windows programming in several languages (C/C++ for us) with support for Win-32 APIs Project-based programming

MS Visual Studio To create a new project: 1. Win-32 API Console Application 2. C++ / Empty project Advices: 1. #include in each file that uses Win-32 APIs 2. #undef UNICODE before including 3. you can write both C and C++ code

Unix Programming Many different IDEs (Eclipse C/C++, Anjuta, Dev-C++, KDevelop) but also text-editor + makefiles

Makefiles Basics: 1. for each target there are compilation rules 2. rules are simple compilation commands 3. variables can be defined to improve generalization 4. use standard targets for good-practice programming

Makefiles - syntax target: [dependencies] rules Any simple identifier Compilation commands (gcc...) (can use variables) other targets that you need to execute first YOU MUST INSERT a TAB SPACE!!!

Makefiles - example 1 SRC = main.c compile: gcc $(SRC) -o my_first_program

Makefiles - standard targets all: executes all the targets to perform compilation clean: removes temporary files (objects, etc.) distclean: removes also the executables

Makefiles - example 2 CC = gcc SRC = main.c hello.c EXE = hello all: compile compile: $(CC) $(SRC) -Wall -o $(EXE) clean: rm -f *.o distclean: clean rm -f $(EXE) variables definition targets and rules

Access to shared locations On Windows: 1. Tools -> Map Network drive insert the share folder: \\cclix1\corsi\system- programming On Linux: 1. /export/home/corsi/system-programming
