Hi,
I am building a application on linux. I am getting an error which
relates to undefined reference to a function. I had build same on
other platform, no error comes.
Here is whole error message ...

Can anybody say why it comes and what the solutions?

Probably. But not here. Try comp.os.linux.development.apps or
comp.os.linux.misc
Here in comp.lang.c, we discuss the proper use of the C programming
language, not failure of linkage editors to properly link programs.

<off_clc_topic>
Hint: take another look at that output, especially around the lines
that reference globchat.o. You'll find your problem (but not your
solution) there.

Can't you read?
In your function "MsgCreate" you are referencing
a library function called "EnumProtocolsA"

This function is not defined in your source code
and not in the libraries you provided. The linker
tells you:

I can't link this program because I am missing this
references"

Solution:

Provide a definition for EnumProtocolsA.

<Hint>

This is a windows function defined in the Winsock
library. Since you are compiling under linux
this function doesn't exist.
</Hint>

<Surprise!>
Compiling network code without caring to look at what it
does doesn't work when you go from windows to linux.
</Surprise>
<Solution>
Pay me an unspecified amount of money to do your job.
I'll fix it for you
:-)
