Re: make coverage-html would fail within build directory separate from source tree

[walker]

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.


That's a bit wired.


Add more detailed testing steps:
mkdir build_dir
cd build_dir
/home/postgres/postgresql-13.2/configure -- enable-coverage
make
make check
make coverage-html


thanks

&gt; Hi, hackers
&gt; 
&gt; During installation from source code, I created a build directory separate 
from the source tree, and execute the following command in the build directory:
&gt; /home/postgres/postgresql-13.2/configure -- enable-coverage
&gt; make
&gt; make check
&gt; make coverage-html
&gt; 
&gt; 
&gt; However, while executing make coverage-html, it failed with the following 
error messages:
&gt; /bin/lcov --gcov-tool /bin/gcov -q --no-external -c -i -d . -d 
/home/postgres/postgresql-13.2/ -o lcve_base.info
&gt; ...
&gt; geninfo: ERROR: no .gcno files found in /home/postgres/postgresql-13.2/!
&gt; make: *** [lcov_base.info] Error 255
&gt; make: *** Deleting file 'lcov_base.info'

Hmm, it works fine for me.&nbsp; config.log says I do this (in
/pgsql/build/master-coverage):

&nbsp; $ /pgsql/source/REL_13_STABLE/configure --enable-debug --enable-depend 
--enable-cassert --enable-coverage 
--cache-file=/home/alvherre/run/pgconfig.master-coverage.cache 
--enable-thread-safety --enable-tap-tests --with-python --with-perl --with-tcl 
--with-openssl --with-libxml --with-tclconfig=/usr/lib/tcl8.6 
PYTHON=/usr/bin/python3 --prefix=/pgsql/install/master-coverage 
--with-pgport=55451

I do run "make install" too, though (and "make -C contrib install").
Not sure if that makes a difference.&nbsp; 
But for sure there are no .gcno files in the source dir -- they're all
in the build dir.
