cmake version > 3.0 ? about xlearn

[aksnzhy]

@xxyy1 Hi, you can follow this page to update your CMake. http://xlearn-doc.readthedocs.io/en/latest/install_cmake.html

[xxyy1]

install cmake
Loaded plugins: changelog, priorities
942 packages excluded due to repository priority protections
Package cmake-2.8.12.2-2.el7.x86_64 already installed and latest version
Nothing to do

when i install xlearn from pip
why tips "Exception: Please install CMake first" ?

[aksnzhy]

Because xLearn requires CMake version > 3.0, so you get this exception.

We changed our CMake minimal requirement to 2.8. Now you can try to build it from source code.

build from source code

[aksnzhy]

Why your compiler does not support the standard library? Can you find these libraries like pthread on your machine?

[xxyy1]

sorry,
This is the first time to meet this problem.
What path to look for, what to find？
How to solve this problem？

[aksnzhy]

Don't worry, can you tell me what OS on your computer? OSX or Linux ?

[xxyy1]

CentOS Linux release 7.4.1708 (Core)

[xxyy1]

Thank you very much for your patience guidance.

[aksnzhy]

It seems that your OS missing some necessary libraries.

Please try the following command:

sudo yum install glibc-static libstdc++-static -y

and then try to build xLearn again. If there still exists problems, please share me the error information.

[xxyy1]

it works! thank you very much~~
