fd-tap-ping example

[Scott]

I have been working through this example, I have it running fine using ./waf --run scratch/fd-tap-ping.

However if I try to compile the example myself and run without waf I run into issues.

Output:

msg="TapFdNetDeviceHelper::CreateFileDescriptor(): Back from execlp(), errno = No such file or directory", file=../src/fd-net-device/helper/tap-fd-net-device-helper.cc, line=282 terminate called without an active exception

msg="TapFdNetDeviceHelper::CreateFileDescriptor(): socket creator exited abnormally", file=../src/fd-net-device/helper/tap-fd-net-device-helper.cc, line=309 terminate called without an active exception

Aborted (core dumped)

I've been looking through the source but I cannot figure out what the waf run is doing differently, also this is with ns3.23.

Any suggestions will be appreciated.

Thanks,

Scott

Hi,

the point is that waf is also setting up a lot of shell variables. Try using "waf shell" and then running the example from there.

Have fun,
