AW: Net SNMP Application Development using Eclipse

[Michael Jäger]

I downloaded a net-snmp-5.5.zip and extracted it in a msys folder.



When following the introduction on the net-snmp page I get confused.

Configure net-snmp using the configure flags as shown:



BASEDIR=c:/usr



./configure --prefix="$BASEDIR" \

--with-mibdirs="$BASEDIR/share/snmp/mibs" \

--with-mib-modules="agentx disman/event-mib examples/example" \

--disable-embedded-perl --without-perl-modules \





Do I have to configure the net-snmp.zip content or do I have to configure
the installed “stuff” on windows, since I’m assigning my windows netsnmp
installation folder to BASEDIR.

Nevertheless, when configuring I’m getting and error which makes following
“make” not possible:



checking for nlist in -lelf...no

checking for library containing socket... no

configure: error: socket(2) not found.



Sorry for bothering you Bart, but I’m pretty clueless about those things.



Cheers and regards

Michael

Hello Bart,



thank you for your fast reply.



Can you tell me how to change the MSCV header to the Unix header? I’m not
sure how to recognize that it is that kind of error, but I’m not familiar
with eclipse.



I only have one net-snmp-config.h files on my pc. It is located in

C:\Net-SNMP\usr\include





Could you tell me a little bit more please?




Hello Michael,

You should remove the currently installed Net-SNMP headers, download the
appropriate Net-SNMP source tar archive, open a MinGW/MSYS shell, extract
the Net-SNMP tar archive, configure it (./configure ...), build and install
it (make && make install). Then you will have MinGW-compatible Net-SNMP
headers available in the location that was specified via --prefix=...

Please send further questions to the Net-SNMP coders list such that the
other Net-SNMP maintainers also can have a look at them.

Bart.

Please try Net-SNMP 5.6.pre3. If you get the same issue with Net-SNMP
5.6.pre3, there is an issue with your MinGW setup.

I compiled and "made" the net-snmp libraries from version 5.6-rc3.

When I set up a new project in eclipse and compile my application the following error occurs. I made no specific adjustments regarding including libraries or something like that in eclipse.
The #include statements are not marked as an error.

It seems to be the same error as before? I don't know. When I press right click -> open declaration on function of the net-snmp library I am redirected to the respective header file, thus I am wondering why
such an error occurs .

It's not really the same. All the functions listed above are defined in the
Net-SNMP library. If you want to use functions from that library, you have
to tell your compilation environment that it has to link against that
library.

Hi Barth,



Thx for your reply. I added some linker entries like shown in the following

Maybe you have an idea about this. Sorry again for inconvenience.

I see two errors:
- You must use forward slashes in MinGW / MSYS paths instead of backward
slashes.
- The library path is not correct: .../net-snmp/include/... contains header
files, not libraries.
