Yandex maps mobile modifying problem

[c-villain]

Hi,
I am currently using ur tools to modify binary framework Yandex maps mobile...
Link to framework is taken from here...
Every time am getting zerofill error...

ld: in /Users/c-villain/Library/Developer/Xcode/DerivedData/Utkonos-flitswrpfdrvoncmykfarjwnxqce/Build/Products/Debug-iphonesimulator/YandexMapsMobile.framework/YandexMapsMobile(YMKSearchMasstransit2xObjectMetadata_Binding.mm.o), section __DATA/__bss has type zero-fill but non-zero file offset file '/Users/c-villain/Library/Developer/Xcode/DerivedData/Utkonos-flitswrpfdrvoncmykfarjwnxqce/Build/Products/Debug-iphonesimulator/YandexMapsMobile.framework/YandexMapsMobile' for architecture arm64

build on Xcode 13.3.1

any ideas what's going wrong?...

@bogo I've checked this out very thoroughly. It appears that the Yandex SDK has non-zero offsets in S_ZEROFILL sections before the modification. So the iPhone version also doesn't build. This is not a problem with the Transmogrifier.

I've additionally discovered some Unix horrors in the Yandex SDK:

• The original ar file format does not support file paths, only file names. GNU ar supports paths but macOS doesn't have it.
• It's possible to add multiple different files with the same name to an ar archive and the linker accepts this.
• When extracting using ar x, the files with the same filename overwrite each other so only one ends up extracted.
• This overwrite also happens with files that have differently cased names because macOS isn't case-sensitive (e.g. Initialize.cpp.o and initialize.cpp.o).
• It's not possible to extract these separate file instances by using ar directly. Only possible by a hack, e.g. extracting the first one using ar p and then removing it using ar d in a loop.
• Adding files to an archive using ar crv also conflates the different copies that have the same name. To append, ar cqv needs to be used.

I've made a hacked build of xcframework_converter that handles all of this, plus the zero-fill patch: https://github.com/igor-makarov/XCFrameworkConverter/releases/tag/0.4.0-hack-zerofill

@igor-makarov Hey, Igor. Thanks for your work on converter. I tried the patched version to fix an issue for YandexMapsMobile, but still have same error on device build (arm64). I tried 0.7.0 version and 0.4.0-hack-zerofill separately. Same error!

I'm using converter from Podfile. I'm in Xcode 14.0.1 right now.

Hey @mixdesign! I haven't looked at the new versions of the Yandex SDK because I don't actually use it.

It appears that the Yandex company isn't maintaining it very well, and I'm not sure how sustainable it is to constantly work around its quirks. I haven't got bandwidth right now to check it again.

Sorry about the late reply, but I don't have an answer.

@mixdesign
Although now that I recall it, the newest SDK versions are supposed to have XCFramework packaging and not require the converter.

@igor-makarov yeah, thanks for your time and thoughts. I just found that there are fresh libs based on xcframeworks :) Link: https://github.com/CocoaPods/Specs/tree/master/Specs/d/d/0/YandexMapsMobile
