Torch7: Installation failure

Created on 13 Aug 2015  路  18Comments  路  Source: torch/torch7

Hi,
I have been trying to install torch and am getting an error. I used the instructions on http://torch.ch/docs/getting-started.html#_
This is my stack after the third attempt :

what OS (ubuntu, osx etc., which version)? 32-bit or 64-bit? did you run the install-deps script to install all dependencies?

soumith picture soumith on 16 Aug 2015

If its redhat, try yum install readline-devel

hughperkins picture hughperkins on 16 Aug 2015

I am on Ubuntu 14.04.3 LTS 64 bit.
I ran the commands in the same order as they appear on the official page. Was there any background installation I had to do prior to that ?

@darshanime I got the same problem!

Looks like you're missing libreadline-dev, but I can see this in the install script https://raw.githubusercontent.com/torch/ezinstall/master/install-deps Maybe post the output of running install-deps

johnny5550822 picture johnny5550822 on 21 Aug 2015

I figure out the problem because I am using a different gcc version which does not have gfortran, so I switch the gcc version to the one that has it and the above error disappear.

johnny5550822 picture johnny5550822 on 21 Aug 2015

Hi,johnny,I met exactly the same problem .I want to know the gcc version you are using

liumangtu picture liumangtu on 28 Aug 2015

So, it gets tricky when you install torch7. I recalled at some point I encounter a problem in compiling a module, which needs GCC 4.4. Then, at some point again, I encounter an error, and then switched to GCC 4.9.

(Either gcc4.4 then gcc4.9; or gcc4.9 then gcc4.4. Don't exactly remember the pattern)

johnny5550822 picture johnny5550822 on 28 Aug 2015

I have tried gcc4.6, it worked for me. It seems that gcc4.8 will also work. And you do not need to change between different gcc versions https://groups.google.com/forum/#!msg/torch7/kpS8d_OGcbE/UaYIhBi1JJMJ

liumangtu picture liumangtu on 29 Aug 2015

Sounds good :) It just happened to me I have these two GCC versions, so I did it in the ways I described.

johnny5550822 picture johnny5550822 on 29 Aug 2015

I had the same problem but got rid of it after installing libreadline-dev:

@liumangtu FYI:

I think while installing-deps, since '-E' flag isn't passed to bash, some dependencies don't get installed properly.

Yes I had the same problem and it get solved with :- apt-get install libreadline-dev.
This is a solution for terminal with new gcc version.
