`sudo make install` installs Eerie to /root/.eerie

Following the installation instructions in the Io readme, I performed the following steps:

~$ git clone --recursive https://github.com/IoLanguage/io.git
~$ mkdir io/build
~$ cd io/build
~/io/build$ cmake ..
~/io/build$ make -j 4
~/io/build$ sudo make install

This installed Io to /usr/local/bin, as expected, but it installed Eerie to /root/.eerie, leaving me unable to access it without sudo. I tried moving it to my home directory, but there are a lot of links to update.

Thanks for the report. Unfortunately, I can't test configuration on any possible Linux distributive. It tested on Ubuntu and there it works. I'll look into it when I'll have some free time, but I'm not sure that I will in the near future... If you interested, you can debug it yourself.
If you get this error, it means that Io returns /root/.eerie for:

"~/.eerie" stringByExpandingTilde

Looks like a bug in stringByExpandingTilde on your platform. This what you can start with. Also if you can confirm that this is related to Sequence, please provide a report on the tracker of the main repo.

I confirmed that "~/.eerie" stringByExpandingTilde returns /root/.eerie when launching Io via sudo. On my platform, sudo is changing my env to be exactly that of root; not sure if this is the default behavior elsewhere. A simple workaround is to use sudo -E make install.

It would be nice to check $SUDO_USER to get a better guess at the user's home directory, but since "~user/.eerie" stringByExpandingTilde doesn't get user's home, that seems like a lot of work to implement, and it might not be the right call in all cases, e.g. for a multi-user installation.

[ales-tsurko]

On a unix platform stringByExpandingTilde relates only on the value of $HOME, so the expanded part is just the value of $HOME for the current user. Usually, the value of $HOME is the same if you use a command with sudo. But it changes to something like /root or /var/root if you switch to root user with sudo -i though.

ok, it looks like it depends whether you are ubuntu (and macos) or debian: https://unix.stackexchange.com/questions/91384/how-is-sudo-set-to-not-change-home-in-ubuntu-and-how-to-disable-this-behavior

As a workaround you can try to install Eerie separately.

1. Install Io:

git clone --recursive https://github.com/IoLanguage/io.git
cd io/
mkdir build
cd build/
cmake -DCMAKE_BUILD_TYPE=release -DWITHOUT_EERIE=1 ..
make
sudo make install

2. Install Eerie:

git clone https://github.com/IoLanguage/eerie.git
cd eerie
io setup.io ~/.path_to_your_shell_startup_script
source ~/.path_to_your_shell_startup_script
