[Solved] Failed to start on Linux

[mdrobulis]

Ran this

clojure -Sdeps "{:deps {paravim {:mvn/version \""RELEASE\""}}}" -m paravim.start

got an exception (stacktrace below )

looks like libvim-clj is using /tmp/lwjgl + $username' + /3.2.3-build-13/libvim.so
path to load the binary and is failing.

What distro are you using? If it's Arch, please try the solution in #5

could be related Library error

[oakes]

If you want to test whether it is failing to load any LWJGL native library, you could clone play-cljc-examples and try running clj -A:dev native in one of the subfolders. If it fails to run the game at all, then maybe the problem is with LWJGL's native library loader (which libvim-clj uses).

Did a window not launch in either case? Paravim is built into the dev command but it's surrounded by a try/catch so it shouldn't prevent the game from launching...

[mdrobulis]

The game launched but Paravim did not... source of the message in LWJGL

[mdrobulis]

the path used to load the libvim.so on my system is /tmp/lwjglmdrobulis/3.2.3-build-13/libvim.so

[oakes]

Just a shot in the dark, but in case it's the same problem as the Arch issue, can you check if you have libtinfo5 installed? sudo apt install libtinfo5

The unsatisfiedlinkerrors from java are difficult because they don't say what system library it couldn't find. AFAIK the only reliable way to get a more specific error is to try to build libvim.so yourself via this repo...

[mdrobulis]

sudo apt install libtinfo5

and it works. I thoght it's due to 3.2.3 RELEASE

Core: The Library.loadSystem & Library.loadNative methods now require a module name parameter. (S)

SOURCE

[oakes]

Yeah the loadNative method had a breaking change which was annoying, but libvim-clj should be calling it correctly as of 3.2.3. So it works now? Maybe I should add a note to the website so more people see it.

[mdrobulis]

Worked fine... till

(slurp "http://google.com")

thats one long line :rofl:

[oakes]

Oh yeah the REPL prints really slowly, I plan on working on that soon. It basically locks up the editor while it prints.

[oakes]

I added a note to the readme. I'll put it on the website as well when i get the chance.
