Thanks. I later found out that libproj has dependency on libtiff. And since libproj is required by GDAL, basically GDAL indirectly depends on external libtiff.

Even Le 15/02/2023 à 01:57, Fengting Chen a écrit : Hi, In the old build system, I was able to build GDAL 3.4 using “—with-libtiff=internal” and “—with-jpeg=internal” . However, ldd on libgdal.so shows that it still depends on libtiff.so and libjpeg.so. How to build GDAL without this dependency?
