Hi Usman, Please mention the gcc and ns-2 versions you are using.
You can find the gcc version by doing gcc -v. Qasim Muhammad Usman <[EMAIL PROTECTED]> wrote: Hi, I need to install an implementation of HCCA mode of 802.11e for ns2. After spending a week of trying to install Qiang Ni's and University of Pisa's implementation on both cygwin/windows or linux I still haven't got far. I have run into errors after errors. Apparently the latest error in cygwin is that of tclcl-mappings.h file related with something about "incomplete declaration of tcl......" On linux..... theres the problem of tk3d.c with error messages of "symbol" dx...... already defined etc etc I don't know why getting a running 802.11e HCCA is sooooo complicated... Anyways, the main problem that I have found out after browsing the net is that the gcc compiler 3 or above has some problems.... so what is usually recommended is to downgrade to gcc 2.95 for ns Can someone please list the simple steps for installing/downgrading the gcc2.95 for cygwin....
