Problems to install fuzzylite 5

[Unknown]

I’m trying to install fuzzylite 5.0, when I run the ./build sh I get an error. Someone know how to fix it?

Error:

Hi tavdov,

what operating system/distribution are you using?

if you search the web for “undefined reference to `clock_gettime’ ” plus your operating system, you may get some solutions.

I think the library that is missing in your system is rt, as fuzzylite links to -lrt, which I am pretty sure contains the clock_gettime.

Let me know if that helps.

Cheers.

I have ubuntu 12.04 LTS. 64-bits

Same problem. I tried to install this rt: http://www.ubuntubuzz.com/2012/03/real-time-linux-installation-on-ubuntu.html.

Didn’t work.

Hi,

I am sorry about this. I must have missed a bit of configuration in CMakeLists.

You could either:
(1) Add the following around line 88 in CMakeLists

if (UNIX AND NOT APPLE)
    set(FL_LIBS rt)
endif()

, or
(2) Download fuzzylite from repository here

Please let me know if this helps.

Vultor: rt should be installed in your system by default. I am afraid it was an issue with me linking in CMakeLists.

Cheers.

It’s work, thank.
I can compile in the terminal, but when I try to run an example in the qtfuzzylite it say me an error

The following errors were encountered:

– Rule block <> has no T-Norm
– Rule block <> has no S-Norm

Do you know why I get this error?

[Unknown]

I can run the example, the problem was that I forgot to put the rule in T-norm and S-norm

Thanks for your responses
