&gt; thanks for your reply. it indeed that there are no .gcon files in source tree directory, they're in build tree directory, which results in failures.

&gt;
&gt; That's a bit wired.
&gt;
&gt;
&gt; Add more detailed testing steps:
&gt; mkdir build_dir
&gt; cd build_dir
&gt; /home/postgres/postgresql-13.2/configure -- enable-coverage
&gt; make
&gt; make check
&gt; make coverage-html

Hmm, my build dir is not inside the source dir -- is yours?&nbsp; Maybe that
makes a difference?&nbsp; Also, what version of lcov do you have?
