Bug#478980: libsqlite3-0: undefined reference to dlsym/dlerror/dlopen/dlclose
Michael Berg
Version: 3.5.8-2
Severity: important
When trying to link some code I'm writing against libsqlite3-0 3.5.8-2,
I get the following error messages from the linker:
=====
/usr/lib/libsqlite3.so.0: undefined reference to `dlsym'
/usr/lib/libsqlite3.so.0: undefined reference to `dlerror'
/usr/lib/libsqlite3.so.0: undefined reference to `dlopen'
/usr/lib/libsqlite3.so.0: undefined reference to `dlclose'
=====
The same code properly compiles and links against libsqlite3-0 3.5.8-1
and earlier versions of the package under Debian.

These symbols was never in SQLite3 itself, they are provided by the
dynamic linker. Please specify -ldl in your LDFLAGS for the linker.
Please report back if your problem remains or not; in the former case,
can you give me your project for testing?

Adding -ldl allows my code to link, but I still view this to be a bug in
the libsqlite3-0 3.5.8-1 package.
$ ldd /usr/lib/libsqlite3.so.0.8.6
linux-vdso.so.1 => (0x00007fffaf9fd000)
libpthread.so.0 => /lib/libpthread.so.0 (0x00002acefb4c3000)
libc.so.6 => /lib/libc.so.6 (0x00002acefb6de000)
/lib64/ld-linux-x86-64.so.2 (0x0000555555554000)
libsqlite3.so.0.8.6 uses libpthread.so.0, but I don't have to specify
-lpthread when I link against libsqlite3 (because libsqlite3 is already
linked against it).
Sine the requirement for libdl is coming from libsqlite3, libsqlite3
should link against libdl.
