Can't setup OpenFL on Ubuntu - NekoAPI interface?

Sky · November 30, 2017, 9:53pm

Hello, I am new to OpenFL / haxe and wanted to give it a go. I followed these instructions:

Per haxe ubuntu setup’s instructions I installed haxe to a folder ~/dev/haxelib

Then via openfl instructions I installed openfl okay. The last step to setup causes an error though:

sky@sky:~/dev$ haxelib run openfl setup
Called from lime/_backend/native/NativeCFFI.hx line 33
Called from lime/system/CFFI.hx line 184
Called from lime/system/CFFI.hx line 332
Uncaught exception - Could not find NekoAPI interface.

Here are my installed versions:

sky@sky:~/dev$ haxelib version
3.3.0
sky@sky:~/dev$ haxelib list
openfl: [6.5.1]
sky@sky:~/dev$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 17.10
Release:        17.10
Codename:       artful

Any suggestions?

Thank you!

So you installed Haxe, like this?

sudo add-apt-repository ppa:haxe/releases -y
sudo apt-get update
sudo apt-get install haxe -y
mkdir ~/haxelib && haxelib setup ~/dev/haxelib

…I was afraid this might happen

We used to maintain our own Linux install scripts to avoid just this sort of problem, but recently switched in efforts for solidarity

This might be due to a missing symlink for libneko.so, like:

sudo ln -s /usr/lib/neko/libneko.so /usr/lib/libneko.so

…I’m not sure if libneko.so is located there on your system, it might be “/usr/local/lib”, or have a suffix, like “libneko.so.1”

If we could figure out what’s wrong in the PPA version, hopefully we could contribute those patches back. If all else fails, you can remove Haxe and Neko, and install using our script, here:

http://builds.openfl.org.s3-us-east-2.amazonaws.com/haxe/haxe-3.4.2-linux-installer.tar.gz

Thank you for your help and patience

I don’t have a symlink for libneko.so in either /usr/lib or /usr/lib/neko/. I do have one for libneko.so.2 though. I tried adding one for libneko.so, but it still fails in the same place. Here’s what I have after my change:

sky@sky:~/dev$ ls -lth /usr/lib/libneko.so*
lrwxrwxrwx 1 root root  25 Nov 30 14:52 /usr/lib/libneko.so -> /usr/lib/libneko.so.2.1.0

-rw-r--r-- 1 root root 99K Nov 10  2016 /usr/lib/libneko.so.2.1.0

And inside my neko folder:

singmajesty · November 30, 2017, 11:13pm

Is there also a “libneko.so” file under “/usr/lib/neko”? If not, does adding one (or a symlink to one) help?

Sky · November 30, 2017, 11:16pm

There was not, but unfortunately adding it did not help:

singmajesty · November 30, 2017, 11:31pm

Okay, could you try removing haxe and neko, and running the install script I linked?

Thank you again for your patience

Sky · November 30, 2017, 11:53pm

Same problem. I first uninstalled haxe, neko, and libneko2, then removed the haxe PPA. I also checked and removed for any leftover files in these paths before the re-install:

/usr/bin/neko*
/usr/lib/libneko*
/usr/lib/neko/*
/usr/lib/haxe
/usr/bin/haxe*

But alas, same error:

sky@sky:~/Downloads$ haxelib run openfl setup
Called from lime/_backend/native/NativeCFFI.hx line 33
Called from lime/system/CFFI.hx line 184
Called from lime/system/CFFI.hx line 332

Also, this is my neko files now if it helps:

Okay, perhaps I am mistaken, and it is not a Haxe install issue. This error has occurred in the past with a bad install, but perhaps we have already exhausted the possibilities there. Could you try and run the following commands?

haxelib path openfl
haxelib path lime

If Lime is not yet installed, could you also run:

haxelib install lime

…then could you try and run the following commands:

haxelib run openfl
haxelib run lime
haxelib run openfl -nocffi
haxelib run lime -nocffi
haxelib run openfl setup -nocffi

Thanks! That seemed to do the trick – looks like I didn’t have lime installed.

Here’s the output from those commands FYI:

Thanks, this must have been a regression, where haxelib run openfl setup now needs Lime to be installed. I’ll dig into this, thanks for your help, and please post again if you have any trouble
