cannot perform caffe make all to install

[Gonzalo Benito]

Hello, i have been wondering here for a month now and still cannot find a suitable solution for the following problem:

When trying to perform 'make all -j8' following the install and compile instructions for Caffe, i constantly get the following error:

AR -o .build_release/lib/libcaffe.a

LD -o .build_release/lib/libcaffe.so.1.0.0

/usr/bin/ld: no se puede encontrar -lhdf5_serial_h

collect2: error: ld returned 1 exit status

Makefile:573: fallo en las instrucciones para el objetivo '.build_release/lib/libcaffe.so.1.0.0'

make: *** [.build_release/lib/libcaffe.so.1.0.0] Error 1

When looking for a solution to this, i came across the simlink op:

within /usr/lib/x86_64-linux-gnu

$ sudo ln -s libhdf5_serial.so.8.0.2 libhdf5.so

$ sudo ln -s libhdf5_serial.so.10 libhdf5_serial.so

Still, whenever i try this i get the following message:

$ sudo ln -s /usr/lib/x86_64-linux-gnu/libhdf5_serial.so.10 /usr/lib/x86_64-linux-gnu/libhdf5.so

ln: fallo al crear el enlace simbólico '/usr/lib/x86_64-linux-gnu/libhdf5.so': El archivo ya existe

$ sudo ln -s /usr/lib/x86_64-linux-gnu/libhdf5_serial.so.10 /usr/lib/x86_64-linux-gnu/libhdf5_serial.so

ln: fallo al crear el enlace simbólico '/usr/lib/x86_64-linux-gnu/libhdf5_serial.so': El archivo ya existe

So i am in a loophole where i cannot make caffe and none of the methods seen so far work.

I have python 2.7 and Opencv 3.1 from Anaconda 4.2 on Ubuntu 16.04

Please, does anybody have an idea on this?

I would unlink those links, you don't need to do this. You need to add the path of hdf5 to your Makefile.config. Look at my config:

If you this doesn't fix the error, perhaps my Youtube video would be helpful:
