[ns] ns-2.33 with gcc version 4.3.0 in Fedora Core 9

[Guray Acar]

Greetings all.

This is not a question. Recently, we changed our OS to Fedora Core 9.  
The C++ compiler that came with it was gcc version 4.3.0.
I had some problems with compiling ns-2.33 with this version of gcc.

Apparently, the new version of gcc is less tolerant with some  
programming styles including assigning constant strings to nonconstant  
char* pointers.
There were some other errors, too.

To cut it short, if you have similar problems, have a look at this  
website http://www.q2s.ntnu.no/~paquerea/ns.php, which was kindly  
provided by Laurent Paquereau at Norwegian University of Science and  
Technology. Quoted from this website is the following text:

FAQ
Warnings generated by newest versions of gcc
Using the newest versions of gcc to compile ns-2 with -Wall triggers  
the following warnings:
warning: deprecated conversion from string constant to 'char*'
warning: suggest explicit braces to avoid ambiguous 'else'
warning: suggest parentheses around && within ||
warning: suggest parentheses around comparison in operand of &
warning: 'typedef' was ignored in this declaration

To ignore the first four types of warnings, add -Wno-write-strings - 
Wno-parentheses on line 3903 in configure.

To correct the files causing these warnings, download and apply this  
patch.


I wasted some time searching for this patch. I hope it will save you  
all some time. Thanks to Laurent Paquereau.

Regards,

Guray
