            Bug ID: 469100
           Summary: Backend process failed to start with exit code 127,
                    undefined symbol: R_GE_clipPathFillRule
    Classification: Applications
           Product: rkward
           Version: unspecified
          Platform: Archlinux

SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug
symbols.
See

***

After installation from Manjaro repository and opening Rkward, it immediately
crashes with an error (check out the error's content in OBSERVED RESULT section
of this bug report). On my machine, the `/usr/bin/R` is symlinked to
`/opt/R/4.1.2/bin/R`. So I though the issue is that Rkward cannot follow
symlinks, so I also ran `rkward --r-executable='/opt/R/4.1.2/bin/R'` which
threw the same error.

STEPS TO REPRODUCE
1. open Rkward (from terminal or from application launcher)
2. observe the error

OBSERVED RESULT

The following error is immediately produced:

> The backend process failed to start with exit code 127, message: '/usr/lib/rkward.rbackend: symbol lookup error: /usr/lib/rkward.rbackend: undefined symbol: R_GE_clipPathFillRule
> '.
> The R backend will be shut down immediately. This means, you can not use any more functions that rely on it. I.e. you can do hardly anything at all, not even save the workspace (but if you're lucky, R already did that). What you can do, however, is save any open command-files, the output, or copy data out of open data editors. Quit RKWard after that. Sorry


EXPECTED RESULT

Not to crash

SOFTWARE/OS VERSIONS

Operating System: Manjaro Linux 
KDE Plasma Version: 5.27.4

ADDITIONAL INFORMATION
---Problem description---

I encountered the error message quoted below. Additionally, I saw the following
symptoms:

> The backend process failed to start with exit code 127, message: '/usr/lib/rkward.rbackend: symbol lookup error: /usr/lib/rkward.rbackend: undefined symbol: R_GE_clipPathFillRule
> '.
> The R backend will be shut down immediately. This means, you can not use any more functions that rely on it. I.e. you can do hardly anything at all, not even save the workspace (but if you're lucky, R already did that). What you can do, however, is save any open command-files, the output, or copy data out of open data editors. Quit RKWard after that. Sorry

What - in detail - did you do directly before you encountered this problem?

I opened Rkward trough any of the following ways:
- KDE plasma application launcher
- terminal and `rkward`
- terminal and `rkward --r-executable='/opt/R/4.1.2/bin/R'`

When you try to repeat the above, does the problem occur again (no, sometimes,
always)?

always

If applicable: When doing the same thing in an R session outside of RKWard, do
you see the same problem?

--Not Applicable--

Do you have any further information that might help us to track this problem
down? In particular, if applicable, can you provide sample data and sample R
code to reproduce this problem?

--Not Applicable--

RKWard is available in many different packagings, and sometimes problems are
specific to one method of installation. How did you install RKWard (which
file(s) did you download)?

```sh
❯  sudo pacman -S rkward

❯  sha256sum $(which rkward)
```

---Error Message---
Message code: r_engine_has_died
The backend process failed to start with exit code 127, message:
'/usr/lib/rkward.rbackend: symbol lookup error: /usr/lib/rkward.rbackend:
undefined symbol: R_GE_clipPathFillRule
'.
The R backend will be shut down immediately. This means, you can not use any
more functions that rely on it. I.e. you can do hardly anything at all, not
even save the workspace (but if you're lucky, R already did that). What you can
do, however, is save any open command-files, the output, or copy data out of
open data editors. Quit RKWard after that. Sorry!
