Caffe: Caffe Compilation Error: LD -o .build_release/lib/libcaffe.so.1.0.0-rc3 /usr/bin/ld: cannot find -lsnappy

[wajahatamin]

I am compiling Caffe framework and i got this error while using the command make all. i have installed the prerequisite dependencies.

LD -o .build_release/lib/libcaffe.so.1.0.0-rc3
/usr/bin/ld: cannot find -lsnappy
collect2: error: ld returned 1 exit status
Makefile:563: recipe for target '.build_release/lib/libcaffe.so.1.0.0-rc3' failed
make: *** [.build_release/lib/libcaffe.so.1.0.0-rc3] Error 1

any help ???

[deepvid]

When you do cmake .., does it find snappy?

Check if you have libsnappy-dev installed, if not do this:
sudo apt-get install libsnappy-dev

[wajahatamin]

thnx sir that one is solved but got this

CXX/LD -o .build_release/tools/upgrade_net_proto_binary.bin
.build_release/lib/libcaffe.so: undefined reference to cv::imread(cv::String const&, int)' .build_release/lib/libcaffe.so: undefined reference tocv::imencode(cv::String const&, cv::_InputArray const&, std::vector >&, std::vector > const&)'

[deepvid]

Looks like you don’t have opencv. Do this:
sudo apt-get install libopencv-dev

Or disable opencv while compiling caffe. Uncomment this in Makefile.config
USE_OPENCV := 0

[wajahatamin]

same error tried both

[deepvid]

Can you share output of cmake with opencv disabled.

[wajahatamin]

see the screenshot ? its with opencv disabled and i am using make not cmake

[deepvid]

Try using the "CMake Build" steps given in installation page.

[jianghaitao]

If your OS is Ubuntu, you can follow the https://github.com/BVLC/caffe/issues and installed the dependencies, which include libsnappy-dev package.

[wajahatamin]

cmake build worked for me thnx mate :+1:

[shelhamer]

From https://github.com/BVLC/caffe/blob/master/CONTRIBUTING.md:

_Please do not post usage, installation, or modeling questions, or other requests for help to Issues._
Use the caffe-users list instead. This helps developers maintain a clear, uncluttered, and efficient view of the state of Caffe.

any one have solution thank you

[hanikh]

@Suraj59 I encountered the same error. have you found any solution for that?

[YerongLi]

I have a similar error with make instruction and cmake instruction does not help.

[YerongLi]

I fixed my problem partly by rebuidling protobuf and after rebuilding it "undefined reference to `google::protobuf ..." disappeared.

But I still have "undefined reference to google::base ..." , undefined reference toundefined reference to cv ..." undefined reference toleveldb ... " errors.

I fixed this by using openblas instead of atlas.

And i did sudo apt-get install libhdf5-dev

Reading package lists... Done
Building dependency tree
Reading state information... Done
libhdf5-dev is already the newest version (1.8.16+docs-4ubuntu1)

What would be the problem?
Anyone faced the problem with this?
any solutions please

Hi,
I uncomment PKG_ CONFIG and it works

[poweryin]

cmake build

hi，I meet the same error with you， I want to ask you how to use “cmake build”，thanks
