Ebar & Gbar

Terminals

Students attending this course have access to 

  1. the terminals in the G-bar, build. 308.
  2. terminals in the Ebar, building 341.

C++ Compiler

In the Ebar the default GNU C++ compiler is gcc 2.95.3.

In the Gbar the default GNU C++ compiler is  gcc 2.8.1. If you have problems with compilation of ANSI C++ programs you may change to the new gcc  2.95.2 by setting the environment variable GCC_VERSION to 2.95.2 : 

setenv GCC_VERSION 2.95.2

You can enter the command above in the terminal window where you run make or put it in your tcshell setup-file .tcshrc . You can always see the version of the c++ compiler you are using by typing g++ -v .

Call of compiler:

g++ compile and link
g++ -c compile, do not link
g++ -o file place output-file in file
g++ -O1
g++ -O2		 compile and optimize
g++ -v print version number of gcc

All combinations of the above shown parameters may be used.

Emacs

When editing C++ programs you can have highlighted syntax. If you don't have it, just use the menu Help/Options/GlobalFontLock.

When your program consist of many files use the speed-bar to easily change from one file to another and move to the source for a specific class method, Menu: Tools/DisplaySpeedbar.

If you have a makefile you can compile from inside emacs, Menu: Tools/Compile Return.

For customization of emacs see The very unofficial dotemacs home.

Book Examples

The program examples in the book: C++ for C programmers is available from addison-wesley. However, the source seems to contain bad line-shifts (13's) which the egcs-compiler does not like. The source text with correct line-shift's (10's) is available here. In the Linux-bar the source text can also be taken from the catalog  

~v0283/kurser/49423/book-exs/ .

C++ Library Reference

Remember, you have a full C++ Library Reference available at Dinkum C++ Library Reference
