error installing torch on centos

[Martin Delgado]

Hi everyone,

I would like to ask you if you could help me with this error that I'm getting when I try to install torch on centos 6.6

I don't have root access and most of the dependencies I have installed them by compiling from source in my home directory.

I have also installed readline from source in my home directory and I've set the lib and include directories to env variables such as INCLUDE and LD_LIBRARY_PATH.

The error that I'm getting is the following one:

gcc -O2 -fPIC -I/home/user/torch/install/include -c utils.c -o utils.o

gcc -shared -o treplutils.so -L/home/user/torch/install/lib utils.o

gcc -O2 -fPIC -I/home/user/torch/install/include -c readline.c -o readline.o

readline.c:7:31: error: readline/readline.h: No such file or directory

readline.c:8:30: error: readline/history.h: No such file or directory

readline.c: In function ‘f_setup’:

readline.c:259: error: (Each undeclared identifier is reported only once

readline.c:263: error: ‘rl_completer_quote_characters’ undeclared (first use in this function)

readline.c: In function ‘f_readline’:

readline.c:276: warning: initialization makes pointer from integer without a cast

Error: Build error: Failed compiling object readline.o

Can anyone help out?

Were you able to solve this issue? I am having the same problem. I too do not have root access so unable to install libreadline-dev globally. I downloaded the libreadline-dev rpm package and installed locally, but unable to point the compiler to it.

Finally solved the problem. In case anyone else faces this problem this is what I did.

1) I compiled from source and installed readline locally. (using ./configure --prefix=/path_to_my_local_dir, make, make install) 

2) Set GCC library paths so it cant find them. 

export LIBRARY_PATH = /path_to_my_local_dir/lib:$LIBRARY_PATH

export CPATH = /path_to_my_local_dir/include:$CPATH 

My system is CentOS 7.2 and gcc 4.8.5
