سلام
برای نصب شبیه ساز NS2-2.34 در Ubuntu 10.10 دستور زیر رو وارد کردم:
mohsen@mohsen-K43SJ:~/ns-allinone-2.34$ sudo apt-get install build-essential autoconf automake libxmu-dev gcc-4.3
اما پیغام خطا میده:
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package autoconf is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted,
or
is only available from another source
E:
Unable to locate package build-essential
E: Package 'autoconf' has no installation candidate
E:
Unable to locate package automake
E:
Unable to locate package libxmu-dev
E:
Unable to locate package gcc-4.3
E: Couldn't find any package by regex 'gcc-4.3'
خیلی عجله دارم. لطفا راهنمایی کنید.
