Hi, I am @kojix2 and maingainer of LibUI (Ruby binding of libui-ng), the backend of glimmer-dsl-libui. Could you tell me what OS and libui version you are using?
Also, if you don't mind, could you show me the entire error message? |
|
@kojix2 Thanks for the quick response and apologies for not posting the details up-front. Github was rejecting my copy-pasted stacktrace, and I wanted to make sure I didn't forget to post anything, but I was in a bit of a hurry. |
|
And, although my architecture is probably obvious from the above dump, here it is for completeness. 🙂 |
|
I see this error as well. |

@nevans, @GyozaGuy The libui-ng shared library is built on Use require "glimmer-dsl-libui"

I see... I have reproduced the problem. I would like to look into the cause.

I found the cause of the problem. In April, in libui-ng, pull request #189 unix: Fix uiWindowContentSizeChanged() was merged.

I understand where the problem lies, but there is room for discussion on how it should be fixed. Should we ask the libui-ng team to make changes to the code so that |

In the meantime, in glimmer-dsl-libui 0.11.3, I downgraded the dependency down to the 0.1.2.pre LibUI binding. Could you all please try glimmer-dsl-libui 0.11.3 and see if it resolved the crashing issue? |
@kojix2 that sounds like a good idea. Please do so. (For example, this is possible in SWT, so it should be possible in LibUI too.) |

@nevans Did you try my suggestion to upgrade to a newer version of glimmer-dsl-libui to resolve this issue (it worked for @GyozaGuy )? You can try version 0.11.6 now as that's the latest. Please confirm if it resolves your issue as it was caused by an upstream upgrade of the C libui library, which had a bug, so I changed the glimmer-dsl-libui dependency version to a previous version that works (no bug), and it should work now. |
