[Condor-users] Problems when compiling NS-2 (network simulator 2) with Condor

["Shiyang Zhao" <zhaoshiyang@xxxxxxxxx>]

hi, all

 

I need Condor's checkpointing library during the NS-2 (network simulator 2) simulation, so need to compile NS-2 with Condor.

 

I installed Condor 6.8.6 on a Redhat Linux 9.0 (Linux 2.4.20, glibc 2.3.2) computer, and NS 2.31.

 

I modified the NS-2 Makefile following the way BGP++(http://www.ece.gatech.edu/research/labs/MANIACS/BGP++/) used, by appending the -DHAVE_CONDOR on the DEFINE macro and the -lcondorsyscall in the LIB macro in the Makefile of NS-2.

 

And then some errors occurred during make, error message as follows:

****************************************************************************

I searched these errors, found that the '__no_r_state', 'deflateEnd' were in the Zlib.h. And '__opendir', '__closedir', '__readdir', '__libc_missing_32bit_uids' and so on were some parts of glibc.

 

I think maybe the Make tool cannot find the libraries, but  not sure.  If it was the problem, what should I do to add the right library path?

 

Thanks in advance.
