Hello everyone,

I have to work on some simulations with ns 2.26 which needs gcc 2.95 installed in order to be compiled.

Currently i have installed gcc 4.1 and ried to instal also 2.95 fllowing some instructions i found in Internet.

http://www.mjmwired.net/resources/mjm-fedora-gcc.html

When trying to compile the gcc i get this errors:

make[1]:***[libgcc2.a] Error 1
make:***[all-gcc] Error 2

Can someone help me pass this errors...i am out of time and i would really need some help!

thnx. in advance!

First thing I'd try before trying to install an ancient GCC would be installed the latest version of ns, which is 2.33, from April 2008.
One should expect it to be recent enough to compile with a recent GCC.

Will download and test.
Also, as I'm running an upgrade I cannot check the Fedora-repo. But did you have a look if it's maybe available there?

thnx for the reply!

I have to use ns 2.26 because i need the bgp++ module which works only with this version...which by the way seems to need this older version of gcc.

What do you mean with Fedora-report?! The report after the installation???
Sorry for the ignorance but i am not a "Linux Expert"

With Fedora-repo I mean the software-repository from which you get additional software and updates.
But I checked in the meantime and it's not there.

I have a working gcc-2.95 on a couple of Fedora's.
Which version of Fedora is used ? ?

The gcc package
http://packages.debian.org/etch/gcc-2.95
i386
http://packages.debian.org/etch/i386/gcc-2.95/download
Must be converted to "rpm" with the command
# alien -r <package>

Same goes for the 'cpp' part of gcc-2.95 ( also required )
http://packages.debian.org/etch/cpp-2.95
http://packages.debian.org/etch/i386/cpp-2.95/download
.....
You may need the g++-2.95 package too. ( c++ compiler ).
....
Did you try with the 'compat-gcc-34 and 'compat-gcc-34-c++' ?
> > # yum install compat-.........

Thnx Reptiler!

Knudfl thnx for the links.
I tried installing gcc-core-2.95 which is suposed to have g++2.95 included.
I will donwload also cpp 2.95 and see if the errors wil be solved!
thnx again! I'll let u know!

I forgot to say i am using FC8!

knudfl · 03-27-2009, 02:30 AM

So what is 'gcc-core-2.95' ? ?

The only thing I know by that name is the old
source code, which you will not be able to use
on Fedora 8, AFAIK.

Ok, i got a suggestion that i should install gcc 3.3 before and than compile gcc 2.95 with gcc3.3.

I did install gcc 3.3 but when i run: gcc -v on the terminal i only get: gcc version 4.1.2 20070925.
No gcc 3.3

I installed it in /opt/gcc336/bin and also aded the PATH=$PATH:/opt/gcc336/bin.

I don't know what else can i do!

1) It is not easy to build gcc-2.95 .

2) 'gcc -v' only concerns /usr/bin/gcc, which is gcc-4.1.2 .
2a) The command '/opt/gcc336/bin/gcc -v' will write version,
etc. for that.

3) If you want gcc-3.x : Use the compat-gcc-34 packages,
I mentioned in post # 5.
And using it, example : './configure CC=gcc34 CXX=g++34
... and 'make CC=gcc34' etc.
Probably works better than gcc-3.3.6,
if you compiled it yourself.
