[donald ngugi]

The code am getting gives an error

Trace file generated is Dsdv_Manet_4Nodes_tdma_400txDistance_100SimTime.tr
Creating 4 nodes.
Command ['/home/donalnjeru/ns-allinone-3.26/ns-3.26/build/scratch/tdma-example'] terminated with signal SIGFPE. Run it under a debugger to get more information (./waf --run <program> --command-template="gdb --args %s <args>").

When i run i debugger i get an error

Program received signal SIGFPE, Arithmetic exception.

Hi,

You are lucky that the error comes from an NS_ASSERT.

This means that it is easy to identify the problem.

  NS_ASSERT (m_numCols % m_numRows == 0);

An NS_ASSERT as explained in the documentation "At runtime, in debugging builds, if this condition is not true, the program prints the source file, line number and unverified condition and halts by calling std::terminate."

That means the m_numCols % m_numRows == 0 is false. 

it could be a bug in TDMA module, but since the module is not part of the main ns-3 codebase, we can not provide further support.

You should contact the module's developers/maintainers.

Regards,

K.

is there any code that would run on a different module

Running into the exact same issue here. Am going to contact the module author although I will probably not wait on a patch and might just move to omnet++

Dear Konstantinos,

I also find the same problem,but when I annotate the line of the code and rebuild by "./waf",it happen the same problem:

Program received signal SIGFPE, Arithmetic exception.

0xb7c88cac in ns3::TdmaSlotAssignmentFileParser::ParseTdmaSlotInformation (this=0x811e970)

    at ../src/simple-wireless-tdma/helper/tdma-slot-assignment-parser.cc:110

110  m_numCols = m_numCols / m_numRows;

Is it illegal to do the division between two uint32_t types?

Hi,

signal SIGFPE, Arithmetic exception.

This is your error. This comes usually when you divide by zero. 

Regards,
