Question, please, regarding building the code

Hi again, Folks,

I have more information on the question I posted earlier. Sorry about that…I wasn’t sure if someone 
was going to contact me one on one or not. Bear with me, please. I’m just starting to get to know 
Cygwin. 

In the “lode – LibreOffice Development Environment” document 
(https://wiki.documentfoundation.org/Development/lode), page 4, there are 3 instructions together. 
They are under the title, “Now it is time to build.” Note that the first 2 instructions produce no 
errors, but I’ve included them for completeness:

Cd dev/core
../autogen.sh
../../opt/bin/make 2>&1 | tee build.log

The exact error after executing the last line is:
“Make: *** No targets specified and no makefile found. Stop.”

The part I don’t understand is “2>&1”. Is this indicating a make file somehow that it’s not finding?

Thanks very much for your help!

Susan G.
