关于Xgraph不能执行的问题

Xgraph is not considered important, that's why " ./install

"

just ignores it by errors. ( xgraph files

= 9 years old.)

It may be possible to compile it, by using the Ubuntu patch ?

http://packages.ubuntu.com/karmic/xgraph

[xgraph_12.1-11.diff.gz]

But much easier is :

sudo apt-get install xgraph ygraph

'ygraph' is a modern, more advanced tool ..

http://packages.ubuntu.com/karmic/ygraph

.....

==================== 上面的是ubuntu下的解决办法

问题是在fedora 下使用yum install xgraph不能找到xgraph的安装包

解决办法：

进入未编译的ns-allinone-2.33/xgraph-12.1目录下

敲./configrue

接着make

但是出现如下错误;

--------------------------------------------------------------------------

[root@cj xgraph-12.1]# make

gcc -DHAVE_CONFIG_H -I. -I. -I. -g -c xgraph.c

gcc -DHAVE_CONFIG_H -I. -I. -I. -g -c xgX.c

gcc -DHAVE_CONFIG_H -I. -I. -I. -g -c hard_devices.c

gcc -DHAVE_CONFIG_H -I. -I. -I. -g -c dialog.c

dialog.c: 在函数‘make_msg_box’中:

dialog.c:780: 警告：传递‘getline’的第 2 个参数时在不兼容的指针类型间转换

/usr/include/stdio.h:653: 附注：需要类型‘size_t * __restrict__’，但实参的类型为‘char *’

dialog.c:780: 错误：提供给函数‘getline’的实参太少

dialog.c: 在函数‘getline’中:

dialog.c:899: 错误：实参‘lptr’与原型不符

/usr/include/stdio.h:653: 错误：原型声明

dialog.c:899: 错误：实参数目与原型不符

/usr/include/stdio.h:653: 错误：原型声明

make: *** [dialog.o] 错误 1

----------------------------------------------------------------------

原因：

The standard lib (stdio.h) function getline has been redefined in
<installdir>/ns-allinone-2.31/xgraph-12.1/dialog.c. Quick fix:
Edit the file and change the two references to getline to something
else, e.g. getmyline. Then the program builds...

就是说，把dialog.c中的 所有geline替换成getmyline

接着make.

make完后

make install

别忘了在.bashrc 中添加环境变量哦。

如下：

OTCL_LIB=/home/cj/ns-allinone-2.33/otcl-1.13
NS2_LIB=/home/cj/ns-allinone-2.33/lib
X11_LIB=/usr/X11R6/lib
USR_LOCAL_LIB=/usr/local/lib
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$OTCL_LIB:$NS2_LIB:$X11_LIB:$USR_LOCAL_LIB
#TCL_LIBRARY
TCL_LIB=/home/cj/ns-allinone-2.33/tcl8.4.18/library
USR_LIB=/usr/lib
export TCL_LIBRARY=$TCL_LIB:$USR_LIB
#PATH
XGRAPH=/home/cj/ns-allinone-2.33/bin:/home/cj/ns-allinone-2.33/tcl8.4.18/unix:/home/cj/ns-allinone-2.33/tk8.4.18/unix
NS=/home/cj/ns-allinone-2.33/ns-2.33
TCL=/home/cj/ns-allinone-2.33/tcl8.4.18/library
NS_=/usr/local/bin

#fin pour NS2

别忘了把用户名换成你自己的： ）

测试：

进入ns-allinone-2.33/xgraph-12.1/examples目录下

敲：

xgraph bar.xg

你会看到如下形：



success

enjoy it!
