No access to sudo on a cluster

[ThibauldMichel]

Me and several colleagues have tried to install treePL on a cluster which does not provide access to the sudo command, and only enable the conda installer.

We encountered the same problems using git clone and conda to install treePL. The command make install does not work without the sudo command, and consequently, it is not possible to install the nlopt library.

These error messages show up when using make install in the /treepl/deps/nlopt-2.4.2 directory:

/usr/bin/install: cannot create regular file '/usr/local/include/nlopt.h': Permission denied
/usr/bin/install: cannot create regular file '/usr/local/include/nlopt.f': Permission denied
/usr/bin/install: cannot create regular file '/usr/local/include/nlopt.hpp': Permission denied

Therefore, when running the ./configure command in the treepl/src directory, the following error appear:

--------------------------------------------------------
The nlopt library is required for optimization. In the
deps folder, you can unpack nlopt and run
./configure
make
sudo make install
--------------------------------------------------------

Is there any way to avoid using the sudo command during treePL installation? How to install nlopt and treePL without sudo?

I struggled to install treePL on a server, and just gave up. However, it was tremendously straightforward to install it on my mac through Homebrew. Since the analysis runs pretty fast, I just would like to give this advice for people to save their time and do the thing directly on a personal computer.
