Re: [Tcpreplay-users] how to enable fragroute engine in tcprewrite

[Gabriel G. <gab...@gm...>]

To reconfigure, just run the configure script again.

Usually on first build:
./autogen.sh
mkdir build && cd build
../configure [your options ...]
make

Then for consecutive builds, go to the build directory
../configure [options...] # if you changed the env or the conf
make

If it doesn't work, please look at the file config.log
And share the part about fragroute.
