how to use it on centos system?

Issue summary

can i use it on centos7?

Your system configuration

Operating system (centos7):
CUDA version (cuda8):

[gineshidalgo99]

I am sorry, but we do not have any Centos machine to try it.

The OpenPose code uses c++11 and the same dependencies than Caffe. So if you are able to compile Caffe (with CUDA and cuDNN) of you own on Centos, you should be able to install OpenPose too.

Please, if you are able to install it, a few lines with the basic steps would be highly appreciated for other Centos users.

[liaowang0125]

Compiled OpenPose successfully.

Just as you say,modify the CAFFE_DIR ,and have an compiled caffe is enough.

When I first comment,I met the google::protobuf undefined reference problem,I solved it and can install OpenPose.

Great, thanks for letting us know.

@liaowang0125 How did you modify the CAFFE_DIR, can you please elaborate? Maybe post your makefile?

[liaowang0125]

modify it to the path to your compiled caffe,like: path/caffe @saxenarohan97

Just writing down the steps I ended up running to make things work on centOS.
Create and move to build directory.
Use this command to point cmake to correct libs and include dirs for an existing caffe build:
$ cmake -DCaffe_INCLUDE_DIRS=/caffe-rc3/include/ -DCaffe_LIBS=/caffe-rc3/build/lib/libcaffe.so -DBUILD_CAFFE=OFF ..
It gave the following error issuing make:

Linking CXX executable openpose.bin
/bin/ld: /usr/local/lib/libgflags.a(gflags.cc.o): undefined reference to symbol 'pthread_rwlock_wrlock@@GLIBC_2.2.5'
/bin/ld: note: 'pthread_rwlock_wrlock@@GLIBC_2.2.5' is defined in DSO /lib64/libpthread.so.0 so try adding it to the linker command line
/lib64/libpthread.so.0: could not read symbols: Invalid operation
collect2: error: ld returned 1 exit status
make[2]: *** [examples/openpose/openpose.bin] Error 1
make[1]: *** [examples/openpose/CMakeFiles/openpose.bin.dir/all] Error 2

To resolve this, I added a flag to CMakeLists.txt after which the unix sub-case looks like this:

elseif (UNIX AND NOT APPLE)
  # Turn on C++11
  set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -lpthread")
  add_definitions(-std=c++11)
  set(CMAKE_CXX_FLAGS_RELEASE "-O3")

After the change, issuing cmake and make should build successfully.
When running the demo, make sure to use --display 0 if you face X11 issues. Full command:
$ ./build/examples/openpose/openpose.bin --net_resolution "64x48" --image_dir examples/media/ --display 0 --write_json out

@ankit204
Thanks for the feed-back. I've just pushed a fix to include pthread as you did. Could you try the latest OpenPose and let me know if it works by default? Thanks!

(PS: Instead of -lpthread, I did it in the supposedly right CMake way with find_package, it works in Ubuntu, but I could not test it on CentOS as I don't have it)

@liaowang0125 ,can you tell me how do you solve the google::protobuf undefined reference problem？this is my error msg：

Is this solution still applicable today?

[guker]

it works.
os system: centos7 , default( protobuf 2.6.1, gcc 4.8.5)

1. git clone https://github.com/CMU-Perceptual-Computing-Lab/openpose
2. cd 3rdparty
3. git clone https://github.com/CMU-Perceptual-Computing-Lab/caffe.git
4. cd caffe
5. cp Makefile.config.Ubuntu14_cuda8.example Makefile.config
6. modify blas choice by changing BLAS := open
7. make all # in caffe dir
8. protoc src/caffe/proto/caffe.proto --cpp_out=.
9. mkdir include/caffe/proto
10. mv src/caffe/proto/caffe.pb.h include/caffe/proto
11. cmake -DCaffe_INCLUDE_DIRS=/xxx/3rdparty/caffe/include/ -DCaffe_LIBS=/xxx/3rdparty/caffe/build/lib/libcaffe.so -DBUILD_CAFFE=OFF .. # here /xxx is absolute path of 3rdparty
12. make -j[cpu count]

please keep protobuf version 2.6.1
if compile error, please update gcc version(such as gcc 7.3.1)
update gcc method:

1. yum -y install centos-release-scl
2. yum -y install devtoolset-7-gcc devtoolset-7-gcc-c++ devtoolset-7-binutils
3. scl enable devtoolset-7 bash

Thank you very much. I successfully installed Openpose under centos according to your steps, and you saved me.
