This HOWTO covers installation on Ubuntu Linux.

[소스 다운 받기]

[GDB debugger를 위한 수정]

1. install 파일 수정

1.1 408번 줄에 더하기  --enable-synbols

1.2 498번 줄에 더하기 –enable-debug

2. ns의 Makefile.in수정하기

82번째 줄에 더하기  -g 

3. 필요 패키지 설치하기

3.1 X11/Intrinsic.h 는 otcl1-9 설치시 필요하므로

3.2 /usr/X11R6/include/X11/Xmu/WinUtil.h는 nam-1.1에 필요함

확인 : /usr/include/X11/Xmu/WinUtil.h  에 파일 생성 안되면 아래 링크 이용 http://www.koders.com/cpp/fid8242d90801 ··· 7d0.aspx

4. xgraph Makefile수정하기

4.1 85번째 줄에 더하기 -L/usr/X11R6/lib

5. gt-itm 은  sgb2ns에 필요함

5.1 sgb설치를 위한 apt수정

deb-src http://au.archive.ubuntu.com/ubuntu hoary main restricted deb http://au.archive.ubuntu.com/ubuntu hoary-updates main restricted deb-src http://au.archive.ubuntu.com/ubuntu hoary-updates main restricted deb http://au.archive.ubuntu.com/ubuntu hoary universe deb-src http://au.archive.ubuntu.com/ubuntu hoary universe deb http://security.ubuntu.com/ubuntu hoary-security main restricted deb-src http://security.ubuntu.com/ubuntu hoary-security main restricted deb http://security.ubuntu.com/ubuntu hoary-security universe deb-src http://security.ubuntu.com/ubuntu hoary-security universe deb http://archive.ubuntu.com/ubuntu hoary multiverse deb-src http://archive.ubuntu.com/ubuntu hoary multiverse deb http://archive.ubuntu.com/ubuntu hoary-backports main universe multiverse restricted

5.2 sgb 다운 받기

6. eval 파일 수정

162번째 둘줄로 나누어져 있는 아래 내용을 한줄로 수정

7. gt-itm관련 작업

gt-itm 하부에 bin 디렉토리 없으면 생성

8. gt-itm 와 sgb2ns 필요로 하는 라이브러리 링크 하기

9. 발생 가능 에러 해결

9.1 tcl 컴파일 에러

9.2  make: *** [queue/cbq.o] ## 에러 해결 하기

10. ns컴파일 하기

9.1 install 스크립트로 한번데 되면 좋은데 ...안될경우 각 패키지 별로 설치하며 확인하기

11. Environmental variables.

gcc 에러 보고 되고 있음 : http://blog.naver.com/etenallove/100016553174
