linker doesn't find NVIDIA libraries

[Juan Simón]

I have installed the package 'nvidia-340-updates' and 'nvidia-340-updates-dev'.
When I compile a program that it uses these libraries it fails when it tries to link them:

But

I have try to reconfigure alternative for i386-linux-gnu_gl_conf and this is the output:

There are 2 choices for the alternative i386-linux-gnu_gl_conf (providing /etc/ld.so.conf.d/i386-linux-gnu_GL.conf).

  Selection Path Priority Status
------------------------------------------------------------
* 0 /usr/lib/nvidia-340-updates/alt_ld.so.conf 8604 auto mode
  1 /usr/lib/nvidia-340-updates-prime/alt_ld.so.conf 8603 manual mode
  2 /usr/lib/nvidia-340-updates/alt_ld.so.conf 8604 manual mode

But 'usr/lib/nvidia-340-updates/alt_ld.so.conf' and '/usr/lib/nvidia-340-updates-prime/alt_ld.so.conf' are empties files. Why it doesn't point to '/usr/lib/nvidia-340-updates/ld.so.conf'?

Sorry, I have seen that 'x86_64-linux-gnu_gl_conf' points to correct conf file:

There are 3 choices for the alternative x86_64-linux-gnu_gl_conf (providing /etc/ld.so.conf.d/x86_64-linux-gnu_GL.conf).
