@rremani have you solved this problem?

[rremani]

No , I am stuck at that very point.

[rremani]

In a detailed way,
mkdir: cannot create directory ‘build’: File exists

First I installed torch7 from the site then installed fblualib from the commits given in the issue #1 that you posted.
My torch is installed in Home directory (/home/ce/torch) and fblualib(/tmp/fblualib-build.YTz6tN)in temp pasting both the paths, I feel I need to change the Cmakellists.txt of crnn.

CMAKE_MINIMUM_REQUIRED(VERSION 2.8.7 FATAL_ERROR)

PROJECT(crnn)

FIND_PACKAGE(OpenMP)

SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 ${OpenMP_CXX_FLAGS} -Wall")

Change this line if your Torch7 is installed elsewhere

SET(TORCH_ROOT "$ENV{HOME}/torch/install")

SET(SEARCH_PATHS
"/usr/local/lib"
"${TORCH_ROOT}/lib")

dependencies

FIND_LIBRARY(THPP_LIBRARY thpp
PATHS ${SEARCH_PATHS})
FIND_LIBRARY(LUAT_LIBRARY luaT
PATHS ${SEARCH_PATHS})
FIND_LIBRARY(TH_LIBRARY TH
PATHS ${SEARCH_PATHS})
FIND_LIBRARY(THC_LIBRARY THC
PATHS ${SEARCH_PATHS})
SET(EXT_LIBRARIES ${THPP_LIBRARY} ${LUAT_LIBRARY} ${TH_LIBRARY} ${THC_LIBRARY})
SET(EXT_INCLUDE_DIRS "${TORCH_ROOT}/include" "${TORCH_ROOT}/include/TH")

INCLUDE_DIRECTORIES(${EXT_INCLUDE_DIRS})
ADD_LIBRARY(crnn SHARED init.cpp ctc.cpp)
TARGET_LINK_LIBRARIES(crnn ${EXT_LIBRARIES})

Do I need to change the path for Torch and where it is searching the libraries for the below lines.
SET(TORCH_ROOT "$ENV{HOME}/torch/install")
SET(SEARCH_PATHS
"/usr/local/lib"
"${TORCH_ROOT}/lib")

Thanks

I have met some thing similar, like:

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
LUAT_LIBRARY
    linked by target "crnn" in directory /home/CRNN/crnn/src/cpp
THC_LIBRARY
    linked by target "crnn" in directory /home/CRNN/crnn/src/cpp
TH_LIBRARY
    linked by target "crnn" in directory /home/CRNN/crnn/src/cpp

Tried locating those library manually. I found that my THPP_LIB is actually in somewhere else rather than ../torchroot/lib,then I changed those search path from

SET(SEARCH_PATHS "${TORCH_ROOT}/lib")
FIND_LIBRARY(THPP_LIBRARY thpp
  PATHS ${SEARCH_PATHS})
FIND_LIBRARY(LUAT_LIBRARY luaT
  PATHS ${SEARCH_PATHS})
FIND_LIBRARY(TH_LIBRARY TH
  PATHS ${SEARCH_PATHS})
FIND_LIBRARY(THC_LIBRARY THC
  PATHS ${SEARCH_PATHS})

to

SET(SEARCH_PATHS "${TORCH_ROOT}/lib")
FIND_LIBRARY(THPP_LIBRARY thpp
  PATHS "usr/local/lib")
FIND_LIBRARY(LUAT_LIBRARY luaT
  PATHS ${SEARCH_PATHS})
FIND_LIBRARY(TH_LIBRARY TH
  PATHS ${SEARCH_PATHS})
FIND_LIBRARY(THC_LIBRARY THC
  PATHS ${SEARCH_PATHS})

And it all works !
P.S. I ran those in this docker image bethgelab/jupyter-torch.
Wish it helps~

Thanks @LavieC Lav , I finally was able to run the demo. The major problem was with the successful installation of fblualib which really irritated me. Now, I have created a docker file built on the docker file you provided me docker pull rremani/cuda_crnn_torch .
Thanks again!

[qnkhuat]

@rremani can u help me install thpp ? I'm running ubuntu 16.04

[rremani]

@qnkhuat I can try to help you but it takes lot of time to figure out what the error is actually about. I would suggest you to use docker image rremani/cuda_crnn_torch which has everything installed.
Happy Learning!
