Build issue

[matbs24]

I'm building caffe-segnet on ubuntu 17.10 in modalities CPU-only.

I have this error on terminal. Anyone can help me? I'm a beginner

How did you solve this problem?

[matbs24]

this is the solution. It is a fix for CPU only:

#123

[bermudezarii]

In my case, I had the gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.9)
So the updates they did to the project where causing similar problems.

The way that worked for me was:
Doing the install with this version of segnet:
https://github.com/alexgkendall/caffe-segnet/tree/dba439804e7b65920ffc501098ad8c94650a494e

Or updating the gcc, from version 5 to 7. (:

@bermudezarii
I am also installing the same segnet that you have mentioned for solution but i still getting the same problem.
i have updated gcc from 5 to 7 but when i check the gcc version it still shows 5
i am installing this segnet on ubuntu16.04

plz help me
thank you in advance

[bermudezarii]

When I had this problem, I didn't try changing the version, but that could be that you don't have that gcc like "default".
You could try installing the other segnet (as I did) or setting gcc 7 as default: https://askubuntu.com/questions/942784/install-gcc-7-1-on-xubuntu-16-04-and-make-it-default

Tell me then if you had the same problem.

[AliRaza21918]

@bermudezarii this ERROR is solved by Replacing Line no 56 of contrastive_loss_layer.cpp file
with this
Dtype dist = std::max(margin - (float)sqrt(dist_sq_.cpu_data()[i]), Dtype(0.0));
and make all done successfully
but a new ERROR raised while make runtest
I posted it on
#138
help me

[AliRaza21918]

@bermudezarii I am waiting for your response
