    hi Hrudaya, from your screenshot, it looks like your build is
    failing because some compiler warnings are treated as errors. Scroll
    up and search your console log for the string ": error" to see the
    actual original error message.<br>
    <br>
    Alternately, ensure you do not have the following line in your
    mozconfig file:<br>
    <br>
    ac_add_options --enable-warnings-as-errors<br>
    <br>
    Remove it or change it to --disable-warnings-as-errors. If you have
    any more debugging questions, drop by the #introduction IRC channel
    on Mozilla's IRC server.<br>

                  <div>Hello everyone,<br>
                    <br>
                  </div>
                  To contribute to the development of Firefox, I tried
                  to produce the Firefox build (the debug build) by
                  following the below mentioned links:<br>
                  <a moz-do-not-send="true"
                    href="https://wiki.mozilla.org/Contribute/Firefox">https://wiki.mozilla.org/Contribute/Firefox</a><br>
                  <a moz-do-not-send="true"
                    href="https://developer.mozilla.org/en-US/docs/Simple_Firefox_build">https://developer.mozilla.org/en-US/docs/Simple_Firefox_build</a><br>
                  To make the build process produce a debug build
                  instead of a release build, I simply copy-pasted all
                  the lines mentioned in the above first link into a
                  mozconfig file. (I am using <b>Ubuntu</b> as my OS
                  and have an <b>8 GB RAM</b> in my computer.)<br>
                  <br>
                  However, <b>errors</b> are cropping up during the <b>compilation
                    tier</b> of the build process. Even after running
                  "./mach build" multiple times, the errors are not
                  getting removed. Rather, every time errors are
                  produced on different "lines". I tried the following
                  link for some help, but to no avail:<a
                    moz-do-not-send="true"
href="https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Mozilla_build_FAQ"><br>
https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Mozilla_build_FAQ</a><br>
                  <br>
                </div>
                <b>But, there seems to be a "common pattern" to the
                  error occurences.<i> Initially,</i></b> the errors
                seemed to be "<u>centered around</u>" files having the
                following generic name:<br>
                <br>
              </div>
              <div style="text-align:center"><b><i>lib*.*.o.desc</i></b><br>
              </div>
              <br>
            </div>
            As I ran the build command multiple times, the number of
            warnings issued by the compilation process started to
            increase and <b>now</b> the error seems to be "centered
            around" the following element:<br>
            <br>
            <div style="text-align:center"><i><b>Unified_cpp_xpcom_base0.o</b></i><br>
            </div>
          </div>
          (A screenshot of the current error indication is attached)<br>
          <br>
        </div>
        I would be highly grateful if someone could point out the method
        to eliminate the error. Thanks in advance!<br>
