ZLIB_1.2.9 missing

[yohannd1]

I've been trying to load Loenn since a while, but I always get this error:

Error

error loading module 'nfd' from file './nfd.so':

Investigating the error message on the top, I've tried to install zlib1.2.9 and libpng1.6.37, but they didn't change the problem.

OS: Linux (Ubuntu 19.04)
Loenn version: v0.0.7 (It also happened with the previous version)

I mean it does look like nfd is linked against a different version of zlib. Installing the right zlib version (this issue has plenty of hits in search engines) should do it. Alternatively, you can compile nfd yourself.
Lönn does not directly interface with zlib or libpng at all, and nfd doesn't either as far as I know, so it shouldn't contain any links to it. libgtk-3 should be the only direct dependency. Are you sure your gtk installation is correct?

[yohannd1]

I've tried compiling your fork of nfd (and it was recognized by Loenn), and also tried to fix the problem with this link, but none of these tries worked - the error is the same and the only thing that seems to have changed is the location where Loenn is finding nfd.so (which is now /usr/local/lib/lua/5.1/nfd.so, where I installed it)

In /lib/x86_64-linux-gnu/ (where LOVE seems to find by mounting a temp folder like /tmp/.mount_Du1T6E/usr/../lib/x86_64-linux-gnu/libz.so.1) I've put a symlink to /usr/local/lib/libz.so.1.2.9 called libz.so.1, but that didn't work.

Also, I believe my libgtk-3 installation is correct, but I also have libgtk-2:

You aren't supposed to install nfd anywhere, it goes in the directory next to the .love file.

[yohannd1]

I knew that, and because of that I renamed the nfd.so file in the folder to nfd.so.old to see if it loaded my installed one - and it loaded, but the same error appeared.
And I've tried now to put the new nfd file I built on the Loenn folder and it still didn't change anything.

[Vexatos]

Not sure I can help you with that, it really looks like your GTK installation may be messed up somehow.

[yohannd1]

Okay, but thanks for trying anyway. I actually was going to re-install my OS in some days (or weeks). When I do it I'll try running Ahorn again and post updates here.

[yohannd1]

So, I've reinstalled my OS some weeks ago, and Loenn still didn't work.

I'll try next disabling whatever links to nfd.so in the code to see if it works, there only seems to be references to it in src/filesystem.lua.

[yohannd1]

I've been trying to run Loenn via its source code but, when I try to init the submodules (git submodule update --init), it says that there is no giraffe submodule in .gitmodules. In fact there isn't any declaration of it there, and here in GitHub the src/giraffe folder has a submodule icon, but can't be acessed, where src/selene is also a submodule but can be acessed.

[Vexatos]

Looks like Cruor did a dumb. Fixed that in 5ae1dce.

[yohannd1]

Finally I got it to run!

Just another thing - currently there's only the navigation is available, right? I'm not sure if it's glitched for me, but it's the only thing I can do.

It looks pretty good and is running smooth!

[Vexatos]

Indeed, this looks correct. #1 works on a basic UI, and we're working on a solution as well, but it's taking time. Ahorn is the only fully-featured editor right now.
