Delete branch "%!s()"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
At least in versions
2021.12.01-4-android
and2022.01.15-3-android
I'm getting a segfault when trying to launch organicmaps:edit: fwiw this is with version.sh temporarily patched to always return "2022.01.15" due to #1862
The issue could be with the embedded freetype library not handling your system fonts. Please check its config in 3party/freetype.
Seems like the problem in fonts rendering (also freetype?) within QT.
https://code.qt.io/cgit/qt/qtbase.git/tree/src/gui/text/freetype/qfontengine_ft.cpp#n1100
Yeah, @vng is right, it's internal Qt's error when UI renders some control. Our glyphs are rendered to the texture in OpenGL only.
Do you have any other Qt applications working properly on your machine? Can you compile and run any Qt examples?
Yes, other qt applications compiled the same way work fine. Could it be due to the mismatch between system/qt and bundled freetype versions?
Well, we make static link of 3party/freetype. QT is loaded as dynamic library from so with its own freetype. Here maybe some hypothetical problems with possible freetype global vars initialization and multiple instances of this vars ..
I just tried building #1724 and it works, so it looks like that's the issue
Interesting, how static + dynamic linking of Freetype can cause these issues? I don't have any ideas, except they use the same global variable which is somehow shared between statically and dynamically linked Freetype.
No problem, if global variable will be shared. The problem is that there are 2 instances of global variable. One is initialized but the other one (uninitialized) is used. Classic ODR.
I can confirm that #1877 fixed the issue, thanks!
