Isn't there a way for out-of-source building manually?

[jiapei100]

Hi, all:

I followed the installation doc at http://torch.ch/docs/getting-started.html# and almost have torch installed, which is still NOT there.

I prefer the traditional way to git torch7, and then
mkdir build cd build ccmake ../

But, it looks the ONLY way to install torch is just to follow these 3 lines:
git clone https://github.com/torch/distro.git ~/torch --recursive cd ~/torch; bash install-deps; ./install.sh

2. Since I'm using GCC 5.3.1, I met the error message when I "./install.sh":

The solution should be here:
http://www.visionopen.com/forums/topic/for-gcc-5-3-1/
add set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -D_FORCE_INLINES") at the very front of CMakeLists.txt .

However, it looks like this solution doesn't solve my problem and I still get the above error messages. Any other suggestions?

cheers

[jiapei100]

Ok... yes, problem seems to be solved

Add set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -D_FORCE_INLINES") to every single CMakeLists.txt .

However, I still leave this issue open, for I still have the following warning:

CMake Warning at /usr/share/cmake-3.5/Modules/FindCUDA/make2cmake.cmake:65 (message):
Removing non-existent dependency file: generic/THCTensor.h

[joshxjin]

Can you explain how/where to changed the line? (ie. where are the CMakeList.txt?)

[swearos]

add set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -D_FORCE_INLINES") at the very front of CMakeLists.txt ,in the root folder where you install

[petamem]

@swearos Well, no. What jiapei100 said: " to every single CMakeLists.txt"
Only so it worked.

[noa]

You can fix the warnings by installing the following package:

https://github.com/hughperkins/FindCUDA

luarocks install findcuda

luarocks install findcuda

Error: No results matching query were found.

?

Following what @jiapei100 said, it worked for me in Ubuntu 16.04. I executed this little script in the root of ~/torch folder:

#!/bin/bash
for file in $(find . -name "*CMakeLists.txt" | sed "s|\./||")
do
  echo "trying to fix $file"
  echo 'set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -D_FORCE_INLINES")' | cat - "$file" > temp && mv temp "$file"
done

[soumith]

this should be fixed now

I am still experiencing this issue on Ubuntu 16.04, cuda 7.5 and findcuda installed. I didn't yet move to cuda 8.0 RC as recommended for Ubuntu 16.04 since support in other libraries is missing.

I am having similar error and still the error persist. I tried to add set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -D_FORCE_INLINES") but in vain.

I am on Mac OS X 10.9.5
