Installation error

Hi,

I am trying to install the FedTree and I face following error after running make - j:

I will appreciate it if you could help me to solve the problem

Hi @mahmoudsajjadi ,

Did you set SHARED=on when installing ntl? See below for an example.

wget https://libntl.org/ntl-11.4.4.tar.gz
tar -xvf ntl-11.4.4.tar.gz
cd ntl-11.4.4/src
./configure SHARED=on
make
make check
sudo make install

Hi @QinbinLi ,

Thank you and that works.

Another question is that is python version only works with `GLIBC_2.32'? since I saw the following error after trying to run python examples.

Traceback (most recent call last): File "/c/python/fedtree-2/FedTree/python/examples/regressor_example.py", line 1, in from fedtree import FLRegressor File "/c/python/fedtree-2/FedTree/python/examples/fedtree.py", line 36, in fedtree = CDLL(lib_path) File "/home/mahmoud/anaconda3/lib/python3.9/ctypes/init.py", line 382, in init self._handle = _dlopen(self._name, mode) OSError: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.32' not found (required by /c/python/fedtree-2/FedTree/python/examples/../../build/lib/libFedTree.so)

Hi @mahmoudsajjadi ,

Other versions should also work. I successfully installed and tested the python version on a machine with GLIBC 2.31. How did you install FedTree and python version?

Hi @QinbinLi

Firstly I installed FedTree on Ubuntu 20.04.3 LTS (ldd (Ubuntu GLIBC 2.31-0ubuntu9.9) 2.31) based on the tutorial. After complete installation, then when I am trying to install it on Python 3.9.7 it shows the following error:

Traceback (most recent call last): File "", line 1, in File "/home/mahmoud/anaconda3/lib/python3.9/site-packages/fedtree-1.0.4-py3.9.egg/fedtree/init.py", line 2, in from .fedtree import * File "/home/mahmoud/anaconda3/lib/python3.9/site-packages/fedtree-1.0.4-py3.9.egg/fedtree/fedtree.py", line 43, in fedtree = CDLL(lib_path) File "/home/mahmoud/anaconda3/lib/python3.9/ctypes/init.py", line 382, in init self._handle = _dlopen(self._name, mode) OSError: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.32' not found (required by /mnt/c/python/fedtree-2/FedTree/build/lib/libFedTree.so)

On the other hand, I tried to install FedTree on Ubuntu 22.04, I got the following error after cmake command in the installation:
