module 'cwrap' not found about torch7 HOT 7 CLOSED

hey @pannous, it looks like the lua cant find the cwrap module, this happens when the path/cpath isn't set appropriately (i.e. maybe there's a lua pre-existing in the system that doesn't have the paths properly set).

The fastest way to get going with torch is to use the ezinstall scripts provided by us.

For a global system-wide install:
curl -s https://raw.githubusercontent.com/torch/ezinstall/master/install-all | bash

For installing torch in /local
curl -s https://raw.githubusercontent.com/torch/ezinstall/master/install-all | PREFIX=/local bash

let me know if that doesn't help.

Wow, that was quick and 100% helpful

Well somehow the make file tried to execute the lua files:

[ 51%] Generating TensorMath.c
make[2]: /Users/me/ai/torch7/TensorMath.lua: Permission denied
[ 48%] Generating TensorMath.c
/Users/me/ai/torch7/TensorMath.lua: line 1: local: can only be used in a function

but adding a shebang
#!/usr/bin/env lua -lluarocks.loader
made it work!

Linking C shared module libtorch.so
[100%] Built target torch

Thanks!

Hi @soumith , I used the ezinstall you post but the path to gfortran cannot be found; while if I cmake under torch7/ it can be found, how can I make it work?

Hi @pannous , I met the Permission Denied problem and cannot make it work, where you suggest to put that shebang into?

from torch7.

You have to put it on top of those two lua files which are affected,
I think one was Random.lua I forgot the other one

@ZhangChenyang we just patched the ezinstall scripts and some cmake files to not depend on gfortran!
