Install.sh failed on Mac OS 10.10 about distro HOT 11 OPEN

System: Mac OS Sierra 10.12.4, Mac mini (mid 2010)

I opened the file ~/torch/pkg/torch/lib/TH/CMakeLists.txt and added one line at the 198th as below.

195 # IF ANY SIMD FOUND
196 IF(C_AVX2_FOUND OR C_AVX_FOUND OR C_SSE4_2_FOUND OR C_SSE4_1_FOUND)
197   SET(simd generic/simd/convolve.c)
198   SET(simd ${simd} generic/simd/convolve5x5_sse.c)
199 ENDIF(C_AVX2_FOUND OR C_AVX_FOUND OR C_SSE4_2_FOUND OR C_SSE4_1_FOUND)

The command ./install.sh finished at last.
Definitely, the error is due to not including the c file during the library building. But there must be a better way to fix it.

hey Alex, I am not able to reproduce this. Can you tell me a little more about your machine? Is it an Intel processor? Is it a VM?

It's Mac Mini 2009

uname -a Mac-mini.local 14.4.0 Darwin Kernel Version 14.4.0: Thu May 28 11:35:04 PDT 2015; root:xnu-2782.30.5~1/RELEASE_X86_64 x86_64

Global install via

curl -sk https://raw.githubusercontent.com/torch/ezinstall/master/install-luajit+torch | bash

worked
but I think curl -sk https://raw.githubusercontent.com/torch/ezinstall/master/install-deps | bash
pulled one additional dependency.

I hope it helps.

Has a solution been found for this? I'm having exactly the same problem, same messages entirely except mine says [lib/TH/libTH.0.dylib] instead of [lib/TH/libTH.dylib].

Also having this problem. I'm using a 2009 macbook pro with OS 10.10.9, Intel Core 2 Duo. Here's where it dies:
....

Error. Exiting.

from distro.

This seems to be what happening.

The directory ~/torch/pkg/torch/lib/TH/generic/simd contains files related to the error about convolve5x5. After some examination, I found that the function convolve_5x5_sse is defined in the file convolve5x5_sse.c therefore if SSE is going to be used then the it must be included in the library. However, the CMakeLists.txt does not include the C file when SSE4 is not detected.

@yongduek it worked for me too, thank you !

More confirmation that what @yongduek suggested works (on my El Capitan system). Thanks!

works for me to

Is this issue related to AVX or VT-X tecnology on Processors?
