caffe needs both the google logging and google protocol buffer libraries. Please follow the link to compile and libprotobuf and then compile caffe.

from caffe.

This seems to be a linking error so make sure you don't have multiple (especially old) protobuf .so libraries in your library paths. Both protobuf 2.4 and 2.5 should work, I believe.

Hi guys,
It seems this issue has been wrongly closed while some guys haven't managed to solve the problems with protobuf, protoc, .. So I would like to open this issue and give a thorough solution which would solve most of the problems regarding protobuf during caffe installation;
Here the solution goes:

Make sure you don't have already install protobuf and other similar name files
$ sudo apt-get clean
$ sudo apt-get autoclea
$ sudo apt-get autoremove
$ sudo apt-get remove --purge proto\tab % remove all the files by pressing tab and finding those file or using *.
$ sudo dpkg -P proto\tab

After these steps you are sure that there is no already protobuf in your machine. you can do some of steps e.g. autoremove to make sure.

make sure you've tried installing: sudo apt-get install libprotobuf-dev protobuf-compiler
then download protocol-buffer: https://developers.google.com/protocol-buffers/ for your OS.
afterwards extract it in (Ubuntu)
$ tar zxvf protobuf-2.6.1.tar.gz
$ cd protobuf-2.6.1
$ ./configure
$ make && make all.
if you during make all for caffe faced with error : error while loading shared libraries: libprotoc.so.9: cannot open shared object file: No such file or directory
fix it simly by sudo ldconfig.
if make all in caffe directory gives you error during make all, try this:
mkdir build && cd build
and then make all.
In this way, it's rare that you encounter with any error during the installation regarding protobuf.
Hopefully helps.

from caffe.

my experience: the server version of protobuf is 2.3, which makes "make runtest" give some error, since i don't have root access, so i can only install protobuf2.6 under my $HOME, but when i do "make all", it gives some error like " ... is produced by an older version of protobuf ...", which is due to the messed up of two versions (the default 2.3 and my customized 2.6 under my $HOME), finally i found the solution is in my .bash_profile, i have to add the $HOME/bin and $HOME/lib into $PATH, $LD_LIBRARY_PATH, very important thing to make sure that caffe is using 2.6 instead of 2.3, $HOME/bin and $HOME/lib should be put in front of $PATH, $LD_LIBRARY_PATH like this:

export PATH=$HOME/bin:$PATH
export LD_LIBRARY_PATH=$HOME/lib:$LD_LIBRARY_PATH
export PKG_CONFIG_PATH=$HOME/lib/pkgconfig:$PKG_CONFIG_PATH

to check i typed : protoc --version , it returns 2.6, "pkg-config --cflags --libs protobuf" also gives correct info, then i could pass all the compilation steps.

from caffe.

If you want to remove the old version of the Protobuf, then you can input that sudo apt-get autoremove libprotobuf-dev, then compile the caffe aggain! Of Course, you need install the the Protobuf matually, for me, I installed it by source code(https://protobuf.googlecode.com/files/protobuf-2.5.0.tar.gz).

I had the same problem. It seems that you have different version of google protobuf. I had remove the default installation: sudo apt-get remove --purge libprotobuf-dev

from caffe.

I worked on Ubuntu, I had faced this problem when I start using Caffe, my suggestion:

sudo apt-get install libprotobuf-dev

If this code still not help you remove the error, I think you need delete the libs related with protobuf in your computer, and input the above command again. Ubuntu12.04 has version problem, that's say maybe you need install manually the higher version of protobuf, but in Ubuntu14.04, no this problem. If you can't fixed the error by following the above steps, please provide more info(what type of OS are you used,.. and so on) then we can help you! Here is the installation help page: http://caffe.berkeleyvision.org/installation.html

from caffe.

According to your feedback, I think the libraries should not be remove, at that time, I also faced the phenomenon, after I cd into the /usr/local/lib and /usr/lib to delete the libs, then re-install, the problem solved, this require you had the root or root passwd. The second possible reson is that, becasue you lack the root privilege, so the libs not be inserted into the /usr/local/lib or /usr/lib, so make caffe can't found protobuf, so it gave you the error.

from caffe.

I was having the problems above on OSX10.10 because I installed protbuf, boost, etc in /opt

1. Protobuf issue solved by

export PATH="/opt/protobuf/bin:$PATH"

2. Include file issues

The fix, easy in retrospect, is at the end of cafee-master/Makefile.config look for the following

If Homebrew is installed at a non standard location (for example your home directory) and you use it for general dependencies

INCLUDE_DIRS += $(shell brew --prefix)/include

add things like this

INCLUDE_DIRS += /opt/protobuf/include
INCLUDE_DIRS += /opt/boost/include
...

3. likewise for the link step

LIBRARY_DIRS += /opt/gflags/lib
...

Shell experts can no doubt do these steps in a more clever way..

from caffe.

Dear Shelhamer,
I have already compile google protobuf, the 'google' file is in /usr/local/include, but still I got the above error, does the version of protobuf effect? Many thanks!

from caffe.

IIRC this linking error occurs with protobuf 2.5. I recommend using 2.4 if
you're on 2.5 and getting this error.

Hi,

I'm having issue with google:protobuf and I'm unable to build caffe. I tried with protobuf 3.0, 2.5 and 2.4. For all the cases I'm getting the same error. Looks like its not able to access the google folder in protobuf-*/include. I have also included both the bin and include from protobuf in LD_LIBRARY_PATH and PATH. Please find the attached error. Any pointers would be highly helpful.

Thanks,
spandana

P:S; Looks like its just spitting out build/src/caffe/proto/caffe_pretty_print.pb.o.warnings.txt file.

Thanks for prompt response. Unfortunately I do not have root permissions and I'm using scientific linux (Red Hat 4.4.7-3).

I have installed all the prerequisites etc following the installation.

from caffe.

Oh, I had tried compiling Caffe on CentOS6.5, but I found it very not convenient to install the dependency libraries, so at last I translate to Ubuntu, then everything became fine(Of course, I also meet much trouble, but better than in CentOS). So I think you need clear the installed protobuf first in your computer, and then installed the newer version, maybe this will help...

from caffe.

I did try cleaning up the existing version of protobuf and re-installing newer/older version and nothing seems to be working.

from caffe.

Hmm.. As I dont have root permissions I added protoc in the PATH variable and other lib and include files to LD_LIBRARY_PATH. So, I guess that shouldnt be an issue

from caffe.

I had the same problem and the instructions by @ghost would surely work for anyone on Debian/Ubuntu. I had CentOS but installing 2.6.1 version of protobuf worked for me.

The easiest way to debug and fix the problem that I found is looking at the source of the header file named in the first line of the error. It had the exact version of protobuf mentioned in it which was required to be present for successful compilation. Hope this helps someone! :)

from caffe.

I execute the command "make all" under $CAFFE_HOME, but I met following errors.

I got a very similar error.

Hi guys,
It seems this issue has been wrongly closed while some guys haven't managed to solve the problems with protobuf, protoc, .. So I would like to open this issue and give a thorough solution which would solve most of the problems regarding protobuf during caffe installation;
Here the solution goes:

Make sure you don't have already install protobuf and other similar name files
$ sudo apt-get clean
$ sudo apt-get autoclea
$ sudo apt-get autoremove
$ sudo apt-get remove --purge proto\tab % remove all the files by pressing tab and finding those file or using *.
$ sudo dpkg -P proto\tab

After these steps you are sure that there is no already protobuf in your machine. you can do some of steps e.g. autoremove to make sure.

make sure you've tried installing: sudo apt-get install libprotobuf-dev protobuf-compiler
then download protocol-buffer: https://developers.google.com/protocol-buffers/ for your OS.
afterwards extract it in (Ubuntu)
$ tar zxvf protobuf-2.6.1.tar.gz
$ cd protobuf-2.6.1
$ ./configure
$ make && make all.
if you during make all for caffe faced with error : error while loading shared libraries: libprotoc.so.9: cannot open shared object file: No such file or directory
fix it simly by sudo ldconfig.
if make all in caffe directory gives you error during make all, try this:
mkdir build && cd build
and then make all.
In this way, it's rare that you encounter with any error during the installation regarding protobuf.
Hopefully helps

This answer needs some update, since the latest release is protobuf-3.0.0, after making sure you removed all protobuf related old files,

$ tar zxvf protobuf-3.0.0.tar.gz
$ cd protobuf-3.0.0
$ ./configure
$ make && make all.

Also, change your makefile.config according to the official guide
https://github.com/BVLC/caffe/wiki/Ubuntu-16.04-or-15.10-Installation-Guide
Noting that some part of the instruction is not applicable to the Ubuntu 16.04

Execute the additional commands:

find . -type f -exec sed -i -e 's^"hdf5.h"^"hdf5/serial/hdf5.h"^g' -e 's^"hdf5_hl.h"^"hdf5/serial/hdf5_hl.h"^g' '{}' ;

cd /usr/lib/x86_64-linux-gnu

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

sudo ln -s libhdf5_serial_hl.so.8.0.2 libhdf5_hl.so

The above commands are no longer needed on Ubuntu 16.04 after a certain system update.

from caffe.

apt-get installs a version for libprotobuf-dev [For example 2.6.1] and pip installs the latest [For example 3.3.0] which creates the conflict. Solved this by installing 2.6.1 via pip as well
sudo apt-get install libprotobuf-dev #check the version installed, say 2.6.1
sudo pip install protobuf==2.6.1

Hi, guys, I have meet the similar issue, My protobuf version is 2.6.1 AS follows:

make: *** [.build_release/src/caffe/proto/caffe.pb.o] Error 1

Please Help! thank u guys!

from caffe.

i have compiled caffe on Ubuntu 16.04 LTS both with python 2 and python, it is really a hectic process for beginners, for caffe with python 2.7 make sure that your /.local/lib/python2.7/site-packages only contains a version same as you protoc version. protoc version can be checked by entering
protoc --version
for me i got problems with python 2.7 because by mistake i installed protbuf 3.0 alpha in python 2.7 site packages, so there was a protobuf error after removing it from python 2.7 site packages everything worked fine
also install python-dev version
apt-get install the python3.x-dev
and for python 3.5 make sure you have python 3.0 alpha, if you have both python 2.7 and python 3.x in the system use pip3 otherwise use pip

pip3 install protobuf==3.0.0-alpha-3

or another protobuf such as 3.5 version of protobuf.
also do this
pip3 install python-dateutil --upgrade
after that do
make clean
make all
make runtest
make pycaffe
after performing make all make runtest steps don't forget to do that
sudo ldconfig

hope everything works OK for you.

from caffe.
