babeltrace Format "text" unknown

I am trying to use the babeltrace lib to read a trace file. So here it the flow: 1. babeltrace /var/log/some_trace > trc.txt 2. My program does this in trying to add a trace after creating context:

code
int err = bt_context_add_trace(ctx, path, "text", nullptr,
    nullptr, nullptr);
code
  1. Compile and Run the program gives this error: code [error] [Context] Format "text" unknown. code

The idea is that I have trace generated on multiple machines - and though I can use my program to directly read the binary trace files on my local system, for other systems, I convert the trace using babeltrace and then process all these traces together.

The package I have installed is this: babeltrace-devel-1.2.4-1.el7.x86_64

The third parameter of bt_context_add_trace is the input format's name. For binary (CTF) traces, you will want to use the "ctf" format, rather than "text". You can use the latter as your output format, however.
