I think that this is one :

configure: error: no termcap library found
I search for "termcap" in synaptic but not found it

Windows? Cygwin?

I'm using windows 8.1
What do you mean about Cygwin ?

Can i run EEPRO (ti-89) on Ti nspire cx cas ? (As it is)
I know  that (formula pro) is the ti nspire version but it is not complete
The analysis part missed and that is the important part for me ?
If I want to contact with formula pro team how ?
It's seems that  irc channel  deleted
Thanks in advance

Edited (I make some edit in the code but still has a problem)
The code is :
#include <os.h>
#include <iostream>
#include <stdlib.h>
#include <libndls.h>
using namespace std;
int main() {
   cout<<"!!!Hello World!!!";
   int x ;
   cin>> x;
   cout<<"The  value is :" << x ;
   return 0;
}
The compile result :
>C:\ndless-sdk-v3.6-r53.464a532/mingw-get/msys/1.0/bin/sh -l -c 'PATH="$PATH":\'/C/ndless-sdk-v3.6-r53.464a532/ndless/bin:/C/ndless-sdk-v3.6-r53.464a532/yagarto/bin\' C_INCLUDE_PATH="$C_INCLUDE_PATH":\'/C/ndless-sdk-v3.6-r53.464a532/ndless_pc/include\' LIBRARY_PATH="$LIBRARY_PATH":\'/C/ndless-sdk-v3.6-r53.464a532/ndless_pc/lib\' \'/C/ndless-sdk-v3.6-r53.464a532/ndless/bin/nspire-gcc\' -Os -c hello.cpp'
>Exit code: 0

Built.

When i test it on emu (I'm already install ndless on  emu and check before i run the prog.)
apper a message that prog. not supported
other thing the cpp file is 1 kB
The TNS file is 4.1 MB ? it seems large 

Thank you for reply

Use nspire-io, directly or indirectly. The new SDK at https://github.com/ndless-nspire/Ndless has nspire-io support built-in, just look at samples/newlib.
You can use scanf, std::cin, ifstream, whatever you like.

What is the header file that i will include it will be "#include <nspire-io> ?

It waits for serial input. By default std* are the first UART.

This is my code (I still learning and test small codes)

#include <os.h>
int main() {
   printf ("!!!Hello World!!!");
   int x ;
   scanf("%d" , &x);
   printf ("The  value is : %d" , x)
   return 0;
}
What is the problem for this code (The prog not start to write an input)

Forth : What is the important include that i should write before the program ? " the program contains input from user "

I mean what is the main (#include <>) that without it the app doesn't run ?

Fifth and least : is there any tutorial "pdf or videos " for programming ti nspire cx cas ? can I make a GUI app ?
There is only http://hackspire.unsads.com/wiki/index.php/C_and_assembly_development_introduction_on_Linux. You can use some graphics libs like nSDL, n2dlib or nGL or rip an existing program apart and use its GUI stuff, like pyWrite.

can you give me link contains example for GUI code ?
Thanks in advance
