[gdal-dev] [External] : Re: libgdal.so.36 refers to sqlite library with full path

[Fengting Chen]

Both GDAL and PROJ refer to my custom build sqlite3 library. The sqlite3 entry in PROJ library looks normal, that is, just the library name without path.

My concern is that libgdal.so has libsqlite3.so with full path. How could this happen? How do I remove this?

Maybe another library that GDAL is depending on is linked against the system sqlite3 and not your custom build ? That could be PROJ typically

Hi, I am trying to build GDAL 3.10.3 with sqlite 3.49.2. The build was successful on linux. But there are two entries of reference to sqlite3, and one of it has the absolution path.

> ldd libgdal.so.36 | grep sqlite
ldd: warning: you do not have execution permission for `./libgdal.so.36'
        /scratch/gdal_dir/SDK/sqlite/3.49.2/dist/lib/libsqlite3.so (0x00007f7e08168000)
        libsqlite3.so => / scratch/gdal_dir/SDK/sqlite/3.49.2/dist/lib/libsqlite3.so (0x00007f7dfb00e000)

Why is above listing having a full path of libsqlite3.so built in the libgdal.so.36?

The configuration for the cmake for GDAL is:

set (SQLite3_INCLUDE_DIR          "$(SQLITE3_DIST_DIR)/         include" CACHE PATH "" FORCE)
set (SQLite3_LIBRARY              "$(SQLITE3_DIST_DIR)/lib/     $(LIBSQLITE3)" CACHE PATH "" FORCE)

At the sqlite lib directory, it has:
libsqlite3.a    libsqlite3.so.0@       pkgconfig/
libsqlite3.so@  libsqlite3.so.3.49.2*

Is this sqlite3 build issue or GDAL build issue?

Thanks.
