C and C++ on NYU’s Solaris Unix

Log into Unix

To use the Sun Solaris Unix host i5.nyu.edu, get your loginame (same as your NYU NetID) and secret password (same as your NYU NetID secret password) if you do not already have them. Then connect to i5.nyu.edu via the Secure Shell protocol SSH.

• To connect to i5.nyu.edu from a PC, download a free copy of PuTTY (if you don’t already have it) and launch it. Under Category, select Session. Under Host Name (or IP Address), fill in i5.nyu.edu or 128.122.253.152. Under Protocol, press the SSH radio button. At the bottom of the window, press the Open button.


• To connect to i5.nyu.edu from another Unix host, e.g. from the Terminal application of Mac OS X, download ssh (if you don’t already have it). Run the following command, typing your loginname in place of abc1234.

  ssh abc1234@i5.nyu.edu
  

• To connect to i5.nyu.edu from an iPhone, run TouchTerm.


• To connect to i5.nyu.edu from Android, run ConnectBot.

Unix editors

To edit a file on i5.nyu.edu, use one of the Unix editors:

• /usr/local/bin/pico is the simplest.


• /bin/vi is the most widely used. (I use vi.)


• /bin/vim -g is an improved vi with a graphical user interface. Search for the vim instructions in Handout 3 of my Unix course.


• /bin/emacs has the most features.

Compilers

i5.nyu.edu has three pairs of C and C++ compilers. The ones in teh first column are broken; use the ones in the second column. To get the C++0x extensions, give the command line argument -std=c++0x to /opt/gcc453/bin/g++.

On Linux, install the packages for gcc and gcc-c++ if you don’t already have them.

Compile and run the first program we did in class

cd
pwd

cp ~mm64/public_html/INFO1-CE9264/src/hello.C hello.C
ls -l hello.C

/opt/gcc453/bin/g++ hello.C
ls -l a.out

./a.out
Hello, world!
This is an error message.

echo $?
0

./a.out > output.txt 2> errors.txt
ls -l output.txt errors.txt

./a.out > both.txt 2>&1
ls -l output.txt errors.txt

The program that comprises more than one source file in §1.7.2

cd
pwd

cp ~mm64/public_html/book/src/sources/fg.h fg.h
cp ~mm64/public_html/book/src/sources/fg.C fg.C
cp ~mm64/public_html/book/src/sources/main.C main.C
ls -l fg.h fg.C main.C

/opt/gcc453/bin/g++ main.C fg.C
ls -l a.out

./a.out

The terminal test program in Homework 1.7.3a

The -I. option ensures that the compiler will include ~mm64/book/src/term/term.h, not some other term.h file. The -D option defines the macro UNIX, which is used in the term.c file.

cd
pwd

cp ~mm64/public_html/book/src/term/term.h term.h
cp ~mm64/public_html/book/src/term/term.c term.c
cp ~mm64/public_html/book/src/term/main.C main.C
ls -l term.h term.c main.C

/opt/gcc453/bin/gcc -I. -DUNIX= -c term.c
ls -l term.o

/opt/gcc453/bin/g++ -I. main.C term.o -lcurses
ls a.out

./a.out
