Torch7: Module cwrap is not found (install without sudo)

[i55code]

Hi Soumith,

I am installing Torch on CentOS 6.7 on my lab cluster without sudo. I have tried your one line ezinstall, but it produce the error since I do not have sudo.

So I am installing lua and luarocks to my $HOME and then did the following,

luarocks --from=https://raw.githubusercontent.com/torch/rocks/master/ install torch

The error says cwrap is not found, but I installed cwrap properly:
luarocks --from=https://raw.githubusercontent.com/torch/rocks/master/ install cwrap
Installing https://raw.githubusercontent.com/torch/rocks/master/cwrap-scm-1.rockspec...
Using https://raw.githubusercontent.com/torch/rocks/master/cwrap-scm-1.rockspec... switching to 'build' mode

Updating manifest for /home/zhongzhou/lib/luarocks/rocks
cwrap scm-1 is now built and installed

Since I do not have sudo, what is your advice of going forward? Thank you!

Cheers,
Zhong

+Soumith, is there a way to specify the path for cwrap so that it can be found? Right now the default is to search for it in usr/bin but I installed lua and luarocks in my $HOME and I do not have sudo. Thanks!

you should not use ezinstall, it's outdated. Use the instructions from the website instead http://torch.ch/docs/getting-started.html#_

+fmassa, this link is the first one I tried, it does not work if there is no sudo rights.

-- Looking for dlopen
-- Looking for dlopen - not found
CMake Error at luajit-2.0/CMakeLists.txt:156 (MESSAGE):
Cannot compile a useful lua.

Function dlopen() seems not to be supported on your platform.

Apparently you are not on a Windows platform as well.

So lua has no way to deal with shared libraries!

+Soumith, I have tried all the above ways, it does not work on the server when I do not have sudo rights.

Please advise me in how to proceed.
