Am I missing some step? This error is a bit weird, what you are showing here has nothing wrong. I do work with this coverage target and postgres extensions, and the following steps allow me to generate a text report of coverage when compiling any extension with a Postgres build having --enable-coverage: make install make installcheck make coverage Trying to use coverage-html from an external extension leads to an error: $ make coverage-html rm -rf coverage mkdir coverage /home/ioltas/extra/bin/genhtml --show-details --legend --output-directory=coverage --title=PostgreSQL --num-spaces=4 --prefix= `find . -name lcov.info -print` genhtml: Option prefix requires an argument Use genhtml --help to get usage information But this bit is easy enough to fix by enforcing the value of abs_top_srcdir when running the command "make coverage-html". -- Michael -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
