Fedora 21 Installation Issue: cannot find -lcblas/-latlas

[Alex Dillhoff]

Last week I tried to install Caffe and was met with this error. I now have a bit

more time and was going to try it again.

I have tried specifying the path, but it simply will not install.

I am running Fedora 21. Here is verification of atlas and blas being installed

[localhost caffe]$ sudo yum install atlas atlas-devel blas blas-devel

Loaded plugins: langpacks

Package atlas-3.10.1-18.fc21.x86_64 already installed and latest version

Package atlas-devel-3.10.1-18.fc21.x86_64 already installed and latest version

Package blas-3.5.0-10.fc21.x86_64 already installed and latest version

Package blas-devel-3.5.0-10.fc21.x86_64 already installed and latest version

Nothing to do

[localhost lib64]$ ldconfig -p | grep atlas

libtatlas.so.3 (libc6,x86-64) => /usr/lib64/atlas/libtatlas.so.3

libsatlas.so.3 (libc6,x86-64) => /usr/lib64/atlas/libsatlas.so.3

[localhost lib64]$ ldconfig -p | grep blas

libblas64.so.3 (libc6,x86-64) => /lib64/libblas64.so.3

libblas.so.3 (libc6,x86-64) => /lib64/libblas.so.3

Here is the error that I receive when attempting to build the project.

[localhost caffe]$ sudo make all

LD -o .build_debug/lib/libcaffe.so

/bin/ld: cannot find -lcblas

/bin/ld: cannot find -latlas

collect2: error: ld returned 1 exit status

Makefile:493: recipe for target '.build_debug/lib/libcaffe.so' failed

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

Is there any other information I could provide to help narrow down the cause of the issue?

[Boaz]

Maybe it cannot find it because the atlas library is one directory deeper (/atlas) check if the /usr/lib64/atlas directory is part of the library search path.

The other cblas error seem to be correct, there is no library with that name (note the c before blas).

[Alex Dillhoff]

I forgot to include this from Makefile.config: 

29 # BLAS choice:

 30 # atlas for ATLAS (default)

 31 # mkl for MKL

 32 # open for OpenBlas

 33 BLAS := atlas

 34 # Custom (MKL/ATLAS/OpenBLAS) include and lib directories.

 35 # Leave commented to accept the defaults for your choice of BLAS

 36 # (which should work)!

 37 BLAS_INCLUDE := /usr/include

 38 BLAS_LIB := /usr/lib64/atlas

[Alex Dillhoff]

If I rename the libsatlas.so file and libblas.so file, it compiles just fine.

However, when performing `make runtest`, I am met with the following error:

[localhost caffe]$ sudo make runtest -j8

.build_debug/tools/caffe

.build_debug/tools/caffe: error while loading shared libraries: libcudart.so.7.0: cannot open shared object file: No such file or directory

Makefile:456: recipe for target 'runtest' failed

make: *** [runtest] Error 127

I have added the proper directories to my LD_LIBRARY_PATH. I do not have any idea what I should try from here.

[localhost caffe]$ $LD_LIBRARY_PATH

bash: /usr/local/cuda/lib:/home/me/torch/install/lib:/home/me/torch/install/lib:/usr/local/cudnn/lib:/home/me/torch/install/lib:/home/me/torch/install/lib:/usr/local/cudnn-7.0/lib64:/home/me/torch/install/lib:/home/me/torch/install/lib:/home/me/torch/install/lib:/home/me/torch/install/lib:/home/me/torch/install/lib:/home/me/torch/install/lib:: No such file or directory

[Alex Dillhoff]

All of my issues have been solved.

Even though /usr/local/cuda/lib was in my LD_LIBRARY_PATH, it was still not finding libcudart.so.7.0.

The solution was to perform the following command

sudo ldconfig /usr/local/cuda/lib64

[Boaz]

Renaming a library is almost always a BAD idea.., but, if it works for you...

Can you run ldd on the caffe executable. It should report no missing libraries. If it does, add the path to the library to the LD_LIBRARY_PATH. Just guessing, is there a /usr/local/cuda/lib64 that is missing?

You can use rpm -q <package name> --fileprovide to see where a file is put by yum install.

Another suggestion; maybe the cmake build is easier to get working? From Caffe root dir:

mkdir build
cd build
cmake ..
make all
make runtest

[Alex Dillhoff]

It doesn't look like I have any missing libraries. I should point out that I did keep the original library with its original name. I ended up with a copy of the library renamed so that the project would compile.

This output shows a cblas.h, but I do not know where libcblas.so is.

[localhost lib]$ rpm -q atlas --fileprovide

/etc/ld.so.conf.d/atlas-x86_64.conf

/usr/lib64/atlas

/usr/lib64/atlas/libsatlas.so.3

/usr/lib64/atlas/libsatlas.so.3.10 libsatlas.so.3()(64bit)

/usr/lib64/atlas/libtatlas.so.3

None of these output libcblas.so. Copying libblas.so and renaming it was the simplest solution for me at the time.

I would like to know how I can actually get libcblas.

[Boaz]

Ah, I see.

Maybe this explains: http://nicolas.limare.net/pro/notes/2014/10/31_cblas_clapack_lapacke/

Can yum find the package containing the library? yum provides libblas.so.3

[Alex Dillhoff]

http://www.rpmfind.net/linux/rpm2html/search.php?query=libcblas.so.3%28%29%2864bit%29

 It looks like libcblas.so was provided for earlier versions of Fedora. It simply does not install with atlas-3.10.1-18.fc21.x86_64.

 As far as good practice goes, would it be sufficient to download it from an earlier package?

[Alex Dillhoff]

I have libblas.so. No issues there. I went ahead and downloaded the software from the ATLAS repo and built it on my machine. 

I was able to create a shared library from the output. Kind of a pain, but at least I have learned a few things.

Thank you so much for your replies.

[X.T. Li]

Can you explain how to manually install atblas? I encountered the same problem on Centos, thanks!
