libncurses, last GNAT

libncurses, last GNAT

[Mehdi Saada]

with debian (current stable) 's last repository GNAT I just had a proper bug, with the demand to pass the context to gnu bug tracker (so it really wasn't from my program),
so I installed the version from adacore, and get that:
mehdi:/opt/GNAT/2020/bin$ gnatstudio
/usr/bin/gnatstudio_exe: error while loading shared libraries: libadalang.so: cannot open shared object file: No such file or directory
I've read I had to install libncurses5 but it does nothing. at least not without restarting ?

I had the libncurses problem the other day on Fedora; that's solved by installing ncurses-compat-lib (something like that; not at my Linux box). Missing libadalang is another matter altogether. Installing gnat should have taken care of that. Did you install the Community Edition?

This means libadalang.so is not in $PATH.

You need to in include /opt/GNAT/2020/bin in PATH.

Better to read the actual error message first; it does not mention
libncurses.

I linked the entire content of GNAT/2020/bin into /usr/bin otherwise I could not run gnatstudio without "./".
Besides, I should be able to run these things in the console from /usr/GNAT/2020/bin without problems.
I read about libncurses5, installed it, it changed nothing.
I don't know what else ncurses-compat-lib is supposed to be matched with, within Debian.
the repository version of GNAT crashed with a dignified demand to transmit further the bug report... so I tried a more recent version.

This is a Bad Idea. You should regard the contents of /usr/bin, /usr/lib
etc as sacrosanct.

Well, yes, but you ought to make sure that /usr/GNAT/2020/bin is at the
front of your PATH & run from directories under your $HOME (i.e. under
~/mehdi). Again, you shouldn't put any of your work directories anywhere
under /usr/GNAT/2020.

In case you're new to setting PATH, try for example here:

You were having troubles with libadalang, where did curses come into the
picture?
