Failed to start language server. Bundled clangd: File too short

[sidibu]

Right after starting the IDE, a message occurs in the bottom right saying:

Failed to start Arduino language server: Error: Process exited with exit code: 127

Terminal output regarding this error:

root ERROR Unexpected exit code '127' when executing "/opt/arduino-pro-ide-0.0.4-alpha.preview-linux64/resources/app/node_modules/arduino-ide-extension/build/bin/clangd" with args: ["--version"].

    at ChildProcess.emit (events.js:182:13)
    at Process.ChildProcess._handle.onexit (internal/child_process.js:240:12)

When I try to start the bundled clangd

/opt/arduino-pro-ide-0.0.4-alpha.preview-linux64/resources/app/node_modules/arduino-ide-extension/build/bin/clangd --version

it says:

clangd: error while loading shared libraries: /opt/arduino-pro-ide-0.0.4-alpha.preview-linux64/resources/app/node_modules/arduino-ide-extension/build/bin/../lib/libtinfo.so.5: file too short

Desktop (please complete the following information):

• OS: Kubuntu
• Version 19.10

Additional context
Running the 0.0.4-alpha.preview

Same issue with the new 0.0.5-alpha.preview:

It looks like the symbolic links have not been created correctly while unpacking the application's zip file. Could you try opening a terminal in the unpacked application directory and then executing the following?

ls -l resources/app/node_modules/arduino-ide-extension/build/lib/

If installed correctly, it should display something like this:

lrwxrwxrwx 1 user group      14 Feb 26 19:56 libc++abi.so -> libc++abi.so.1
lrwxrwxrwx 1 user group      16 Feb 26 19:56 libc++abi.so.1 -> libc++abi.so.1.0
-rw-r--r-- 1 user group  308288 Feb 26 18:01 libc++abi.so.1.0
-rw-r--r-- 1 user group      28 Feb 26 18:06 libc++.so
lrwxrwxrwx 1 user group      13 Feb 26 19:56 libc++.so.1 -> libc++.so.1.0
-rw-r--r-- 1 user group 1017080 Feb 26 18:01 libc++.so.1.0
lrwxrwxrwx 1 user group      15 Feb 26 19:56 libtinfo.so.5 -> libtinfo.so.5.9
-rwxr-xr-x 1 user group  193928 Feb 26 18:01 libtinfo.so.5.9

The -> indicate symbolic links. If these arrows are missing, something went wrong when unpacking the archive.

[sidibu]

ls -l resources/app/node_modules/arduino-ide-extension/build/lib/

outputs:

-rwxrwxrwx 1 foo foo      14 Feb 26 18:06 libc++abi.so
-rwxrwxrwx 1 foo foo      16 Feb 26 18:06 libc++abi.so.1
-rw-r--r-- 1 foo foo  308288 Feb 26 18:01 libc++abi.so.1.0
-rw-r--r-- 1 foo foo      28 Feb 26 18:06 libc++.so
-rwxrwxrwx 1 foo foo      13 Feb 26 18:06 libc++.so.1
-rw-r--r-- 1 foo foo 1017080 Feb 26 18:01 libc++.so.1.0
-rwxrwxrwx 1 foo foo      15 Feb 26 18:06 libtinfo.so.5
-rwxr-xr-x 1 foo foo  193928 Feb 26 18:01 libtinfo.so.5.9

So there must have went something wrong when unpacking the archive using KUbuntu Ark.

I tried unpacking the archive with unzip instead of Ark and then the symbolic links where created correctly:

lrwxrwxrwx 1 foo foo      14 Mär  5 12:12 libc++abi.so -> libc++abi.so.1
lrwxrwxrwx 1 foo foo      16 Mär  5 12:12 libc++abi.so.1 -> libc++abi.so.1.0
-rw-r--r-- 1 foo foo  308288 Feb 26 18:01 libc++abi.so.1.0
-rw-r--r-- 1 foo foo      28 Feb 26 18:06 libc++.so
lrwxrwxrwx 1 foo foo      13 Mär  5 12:12 libc++.so.1 -> libc++.so.1.0
-rw-r--r-- 1 foo foo 1017080 Feb 26 18:01 libc++.so.1.0
lrwxrwxrwx 1 foo foo      15 Mär  5 12:12 libtinfo.so.5 -> libtinfo.so.5.9
-rwxr-xr-x 1 foo foo  193928 Feb 26 18:01 libtinfo.so.5.9

The clangd error does not appear anymore.
