Telegram silently fail to start from Live CD

Booted in vbox and installed telegram using pkgman i telegram_desktop

Running Telegram would briefly show it in the Deskbar and quit. There are no messages in the Terminal or in syslog.

I'm guessing it could be a problem in write_overlay file system or atapi driver.

Could a a problem with the binary size which is ~50MB.

Can you run it with strace? strace Telegram from Terminal.

[pulkomandy]

Well it seems to be loaded and start running, and then exits cleanly (exiting starts at 6252 where it deletes a lot of areas as it releases all its memory apprarently).

So I guess extra logging in Telegram itself or in Qt is needed to see why it decided to quit.

I also see various "no such file or directory" errors but I don't know if they are normal or not (checking that a file doesn't exist is fine and would result in this).

Telegram creates log file log_start0.txt in curent directory:

Looks like it failed to create socket file in /system/cache/tmp/.

~> mkfifo /boot/system/cache/tmp/temp
mkfifo: cannot create fifo '/boot/system/cache/tmp/temp': Read-only file system

mh... the write_overlay makes it possible to write there, but I guess mkfifo does not go through it?

[waddlesplash]

The write_overlay does not seem to support "special nodes" (of which FIFOs are one), it just passes through to the next layer down: ​https://xref.landonf.org/source/xref/haiku/src/add-ons/kernel/file_systems/layers/write_overlay/write_overlay.cpp#2194

So, that would probably have to be amended.
