Hi All,

The following code snippet is a part of s/w which is downloaded from
net. While compiling this code I got the following error.

...\..\snmplib\snmpTCPDomain.c(6) : fatal error C1083: Cannot open
include file: 'sys/socket.h': No such file or directory
NMAKE : fatal error U1077: 'cl.exe' : return code '0x2'
Stop.
NMAKE : fatal error U1077: 'C:\PROGRA~1\MICROS~3\VC98\BIN\NMAKE.EXE' :
return code '0x2'
Stop.

I just looked into the code and I found out that the problem is raised
because of sys/socket.h file. So please help me as how to use the
sys/socket.h file in windows OS . I am working on Windows OS. Hence I
am facing the problem. Is there any library I missed out.

Please help me as How to resolev this issue . Your thoughts will be
highly appreciated.

Thanks in Advance.

Thanks
Ravikumar

Did you get a file named socket.h with the software that you downloaded? If
so, where is it? If it is in some directory with a name like

...\sys\socket.h

you need to make sure that the directory that I omitted "..." is one of the
include directories that the compiler searches.

On the other hand, if the software that you downloaded was truly intended to
run on Windows it just might use the file <winsock[2].h> instead to define
things related to sockets.

Of course, it's impossible for any of _us_ to be able to tell _you_ if you
have downloaded Windows or Linux source (or anything else).

Will
