I am trying to install ns-allinone-2.35-RC8 in windows 7 (Cygwin 1.7.22) but i came across this problem. Can somebody give me suggestion to overcome this problem?

Is there any reason why you can't just use the pre-built binaries?

These are located at: http://www.isi.edu/nsnam/dist/binary...n-binaries.zip

Found on this page: http://nsnam.isi.edu/nsnam/index.php...P_Using_Cygwin

rootboy, thank you for the response but ns-allinone seemed to be a better option as all the necessary tweakings and changes are done already. I am trying to use the latest ns2 package because a lot of changes has been made. I need the basic features as of now but i will require other features later. I don't want the hassle of rebuilding the whole stuufs again.

Ref. your posts here :
http://www.linuxquestions.org/questi...-a-4175472232/
→ → gcc-core 4.8.1-3 , gcc-g++ 4.8.1-3 .

** ns-allinone-2.35 cannot be compiled with gcc / g++ version 4.8.x .
** The suggested version is 4.4 ( or 4.6 ).


Remark : The latest "2.35" is ns-allinone-2.35.tar.gz,
RC8 is a release candidate. http://sourceforge.net/projects/nsnam/

Remark 2 : It might be much easier using a genuine Linux OS.
Can be installed into a "virtual machine": 'VM ware' or 'Virtual Box'.
Then you can install any compiler version.

problem solved by using virtual box with Fedora 18. thank you everyone for the help!!!
