Torch7: Lapack library not found in compile time

[sefira]

I installed torch a few days ago by following the guider on Getting started with Torch
Then I try the code on Five simple examples:

xs = torch.inverse(A)*b
print(string.format('J(x^*) = %g', J(xs)))

And then I get the following error

getrf : Lapack library not found in compile time

stack traceback:
    [C]: at 0x7f76dd234b30
    [C]: in function 'inverse'
    [string "xs = torch.inverse(A)*b"]:1: in main chunk
    [C]: in function 'xpcall'
    /usr/local/share/lua/5.1/trepl/init.lua:635: in function 'repl'
    /usr/local/lib/luarocks/rocks/trepl/scm-1/bin/th:185: in main chunk
    [C]: at 0x00406230

as you said on Math Functions-->Eigenvalues, SVD, Linear System Solution

So I retry the script cd ~/torch; ./install.sh
get more error:

How do I fix it?
Should I add some paths to FindBLAS.cmake?
I'm on a Ubuntu 14.04 which be installed in VMware Workstation 10
I need your help,thanks~

Anyone able to help??
I have the same issue!
Thanks in advance!

Does OpenBLAS compile for you guys?

git clone https://github.com/xianyi/OpenBLAS.git
cd OpenBLAS
make NO_AFFINITY=1 USE_OPENMP=1
sudo make install

[korkinof]

Many thanks for your quick response!
I managed to compile and install OPenBLAS as you suggested and this solved my problem!
Many thanks!

Problem solved, so this ticket should be closed, yes?
