Unhappy Having Problem in instaling GNS3 on Fedora 14


Im facing a problem in installing GNS3 Cisco simulator on Fedora 14.

I persistently followed the instructions on the http://www.gns3.net website and the readme that came in with the GNS3 source package.

The main packages needed before running GNS3 are:
Dynamips
Dynagen
Qemu
Qt 4.5.1 (or higher)

Python 2.5 (or higher)

Sip 4.5 (or higher)

PyQt 4.5 (or higher

Ive compiled and installed all the above packages...it took almost a lifetime, especially for Qt and PyQt.

Then, I compiled and installed the GNS3 package and that went well too.

But when I run the gns3 executable, Im getting the error message given below:

[root@mnpc GNS3-0.7.2-src]# gns3
Can't import Qt modules, PyQt is probably not installed ...

I did a double install on PyQt, but the problem still persists.

Can someone tell me where Im going wrong?

Suggest :
Use the genuine Fedora 14 packages instead of building the files.
Then you are sure, that everything is in a default system path ...
1) su
2) yum install qt-devel PyQt4-devel sip-devel qemu


cd GNS3-0.7.2-src/ && python setup.py build && ./gns3 :
... The GNS3 GUI will open.
...

I followed the above steps and the yum installations worked successfully. But, GNS3 still gives the same error...heres a snapshot of the installation and error.

Well, I may have to install Fedora 14, to see what's about.
( I only have Fedora 8 - 9 - 10 - 11 - 12 - 13 installed.)

? GNS3 v0.7.2 is updated in June - 2010, and shouldn't have any
problems with Python 2.7 etc. ? ..

I finally got Fedora 14 installed.

... And sorry, it's the 'PyQt4' that is used by GNS3.
# 'yum install PyQt4' will do.

...

It is a little confusing :
qt , qt-devel is qt4. ( And qt3 : qt3 + qt3-devel ).

"Python-Qt" : Different naming.
PyQt4 , PyQt4-devel ( And PyQt3 is PyQt + PyQt-devel ).
..

Smile At last...Thanks a lot dude.

All installations were smooth...but when I run the ./gns3 package, I get this message...

[root@mnpc GNS3-0.7.2-src]# gns3
Command not found. ./
[root@mnpc GNS3-0.7.2-src]# ./gns3
**
GLib-GIO:ERROR:gdbusconnection.c:2270:initable_init: assertion failed: (connection->initialization_error == NULL)
Aborted (core dumped)


Then I googled this error message and found a solution on the following site:
https://bugzilla.redhat.com/show_bug.cgi?id=638415

Since, I was in root, I was unable to start the application because I didn't have session access.

So, I logged in as another user and ran ./gns3 and success at last.

Thanks again knudfl
