Cannot build code

Hi, when I try to build the code I get this error

`$ make [ 25%] Building CXX object CMakeFiles/caffe_char_rnn.dir/src/Trainer.cpp.o In file included from /usr/include/c++/5/atomic:38:0, from /home/andrewh/caffe/include/caffe/common.hpp:30, from /home/andrewh/caffe/include/caffe/blob.hpp:11, from /home/andrewh/caffe/include/caffe/caffe.hpp:7, from /home/andrewh/caffe-char-rnn/include/Trainer.h:3, from /home/andrewh/caffe-char-rnn/src/Trainer.cpp:1: /usr/include/c++/5/bits/c++0x_warning.h:32:2: error: #error This file requires compiler and library support for the ISO C++ 2011 standard.

Hi,

Hmmm, reading your error, I think you should try with enabling C++11 for your compiler.

[sssss465]

The C++11 error went away after I added it to Cmakelists. However, it is still complaining i am missing nvml.h

[adepierre]

NVML is not part of this code, it's from Cuda. You should check your installation of Caffe and/or Cuda

[sssss465]

I built caffe from source using make and added the include folder to my PATH. After adding the cuda include folder to my path it still does not work. What were the steps you took to get the repository to work?

[adepierre]

I just follow these steps

1. Compiling Caffe with CUDA enable
2. Use CMake to build this project

I've never had any trouble with nvml.h. It seems to be a bug with CUDA rathen than with this code. Make sure everything is working with your installation of Caffe before trying to link it to this project.

Maybe you could first try to compile Caffe without the GPU support to see if everything works correctly.

I have tried the python api and the tests that come with caffe, and both work. I am using nvcaffe

[adepierre]

I've never used nvcaffe. It's probably the source of the problem. I think that nvcaffe only requires the nvidia driver, and not the CUDA toolkit.

This repo is built to work with BVLC Caffe, wich needs the CUDA toolkit to be installed. So if it's an option for you, you could just switch to BVLC Caffe. If it's not possible, I'm affraid you won't be able to use this code directly. Maybe just installing CUDA toolkit (which includes the nvlm.h file) could be enough.

when I run cmake on a fresh install, I get this error.

CMake Warning at CMakeLists.txt:9 (find_package): By not providing "FindCaffe.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "Caffe", but CMake did not find one.

Could not find a package configuration file provided by "Caffe" with any of the following names:

CaffeConfig.cmake
caffe-config.cmake

Add the installation prefix of "Caffe" to CMAKE_PREFIX_PATH or set "Caffe_DIR" to a directory containing one of the above files. If "Caffe" provides a separate development package or SDK, be sure it has been installed.

I have caffe installed in a folder in my home folder

[adepierre]

Did you try to set Caffe_DIR to the path of your install folder (to help him to locate CaffeConfig.cmake) ?

For me it's my/caffe/install/path/share/Caffe/
