I found a crash.log in /home/user/.config/far2l
crash.log

[elfmz]

Regarding your crash.log - looks like crashes happened when you tried to close far2l due to some secondary failure. But to be sure need to see far2l's debug symbols, so - please share your far2l binary.

[elfmz]

Also, do following:
open terminal
type: gdb far2l
when gdb will initialize - type in its command line: run
when GUI far2l will open - reproduce stuck
switch back to terminal with gdb and press Ctrl+C
then type following command into gdb console: thread apply all bt
share also full output of that command (it may prompt for several pages - show all)

[ysharoiko]

After doing run i got error

and it seems i compiled with no debug
For help, type "help".
Type "apropos word" to search for commands related to "word"...
Reading symbols from far2l...(no debugging symbols found)...done.
(gdb) run

My binary is here
far2l.zip

[ysharoiko]

I rebuild it with cmake and -DUSEWX=no
gdb seems to run it, but the problem i faced is that no keyboard shortcut are available.
I can't create new file )
And one more thing, if i close terminal with gdb running, far stays running in background
and starting new far gives message:

Some far2l-s lost in space-time nearby:
 1: WinPort
 2: {/} - Far 2.3 21/04/26-1d847868-alpha x64 user@linux
 3: {/home/user} - Far 2.3 21/04/26-1d847868-alpha x64 user@linux
Input instance index to revive or empty string to spawn new far2l

But if i select one of them i cannot quit it, because F10 is not working (at least in MATE Terminal ) and no exit button is available in menu by F9.
It would be great if exit button would also be in F9 menu.

[ysharoiko]

New binary runnig in gdb
far2l.zip

[elfmz]

Another way - run separate copy, and later attach gdb to it by running gdb --pid=PID_OF_FAR2L
PID_OF_FAR2L can be found by ps aux or echo $FARPID inside of far2l console (before it got stuck)

[ysharoiko]

As soon as i connect to the far2l with gdb by --pid far stops to accept any commands

[elfmz]

But connect after its already stuck on far colorer, then you will not need to send it commands :)
(actually its possible to type continue in gdb to unfreeze app it attached to, and then when need - stop it again by Ctrl+C in gdb, but its really simplier to attach when need to and immediately invoke thread apply all at)

[ysharoiko]

This is what i get when creating new file

[elfmz]

oh, that spdlog... Try to remove/reinstall libspdlog-dev and after that - reconfigre from scratch and rebuild far2l.
If still will not help - send me your /usr/include/spdlog and log of fresh run of far2l's cmake configuration (whats cmake prints to stdout when run on clean build dir)

[elfmz]

Also, try to install libfmt-dev (and rebuild far2l from scratch again)

[ysharoiko]

Did not helped

[ysharoiko]

I found that error is not always happens
But cannot find regularity

I have one xterm opened and it never fails there
But in new xterms or mate-terminal it always fails

The difference that i could found was shim.far2l process does not start in other terminals, only in one that not fails
And it starts if i run from build directory

21438 pts/11   S+     0:00 shim.far2l
21439 ?        Ssl    0:00 ./install/far2l

But If i just put far2l binary into /usr/local/bin, this process does not appear and error on creating file happens.
Does not matter if it was run under user or root

[ysharoiko]

Aga, i replaced /usr/loca/lib/far2l/Plugins directory with new ones and it works now

[elfmz]

well, but how did you install it then initially? It should replace plugins by make install

[ysharoiko]

I did like in README.md
make -j$(nproc --all)
without install
