I just built from current master on my Ubuntu-18.04 VM and SQLite3 is an
option in Save As...

If dpi_initialize_r returns 0 then that function (a libdbi one) didn't find
any drivers to initialize. Make sure that GNC_DBD_DIR isn't set and in gdb
at that dpi_initialize_r call check that driver_dir is 0.

Check that /usr/lib/x86_64-linux-gnu/dbd/lidbdsqlite3.so and
/usr/lib/x86_64-linux-gnu/libsqlite3.so.0 is present.

Hi John,

GNC_DBD_DIR=/         is set in build/etc/gnucash/environment
Commenting that out enables SQLite to work.

Here are the libraries:

/usr/lib/x86_64-linux-gnu/dbd/libdbdpgsql.la
/usr/lib/x86_64-linux-gnu/dbd/libdbdsqlite3.so
/usr/lib/x86_64-linux-gnu/dbd/libdbdmysql.la
/usr/lib/x86_64-linux-gnu/dbd/libdbdpgsql.so
/usr/lib/x86_64-linux-gnu/dbd/libdbdsqlite3.la
/usr/lib/x86_64-linux-gnu/dbd/libdbdmysql.so

/usr/lib/x86_64-linux-gnu/libdbi.so.1.1.0
/usr/lib/x86_64-linux-gnu/libdbi.a
/usr/lib/x86_64-linux-gnu/libdbi.so.1
/usr/lib/x86_64-linux-gnu/libdbi.so

cmake 3.10.2-1ubuntu2.18.04.1

I think the " GNC_DBD_DIR=/" line is added to environment file in
src/gnucash/CMakeLists.txt :

		  if (LIBDBI_LIBRARY AND LIBDBI_DRIVERS_DIR)
		    get_filename_component(libdir ${LIBDBI_LIBRARY}
DIRECTORY)
		    string(FIND ${LIBDBI_DRIVERS_DIR} ${libdir} is_subdir)
		    if (NOT is_subdir EQUAL 0)
		      file(APPEND ${BUILD_ENV_FILE_OUT}
"GNC_DBD_DIR=${LIBDBI_DRIVERS_DIR}")
		    endif()
		  endif()

Before I spend too much time trying to fix this, I am running the build
environment from within eclipse. Is SQLite supported while running from the
build or should I "ninja install" and run from there?

Thanks & Regards,
Chris  Good
