While editing my initial question to add more context as Jay proposed I think it found the issue.

What probably happens? The view where the crash is, contains a table view. Each cell will be configured before being presented. I use a flag which holds the information, if the amount of weight for this cell (it is a strength workout app) has been initially set or is a change. When prepareForReuse is being called, this flag has not been reset. And that now means scrolling through the table view triggers a DB write for each reused cell, that leads to unnecessary writes to the db. Unnecessary, because the exact same number is already saved in the db.

My speculation: Scrolling fast could maybe lead to a race condition (I have read something about that issue with realm) and that maybe causes this weird crash, because there are multiple single writes initiated in a short time.

Solution: I now reset the flag on prepareForReuse to its initial value to prevent this misbehaviour.

The crash only happens when the cell is set up and the described behaviour happens. Therefor I'm quite confident I fixed the issue finally. Let's see. -- I was not able to reproduce the issue, but it also only happens pretty rare.

QUESTION

Xcode error 'building for iOS Simulator, but linking in dylib built for iOS .. for architecture arm64' from Apple Silicon M1 Mac

Asked 2021-Jun-14 at 09:55

I have an app which compiles and runs fine in older Macs with Intel processors in physical devices & iOS simulators.

The same app also compiles and runs fine from newer Apple Silicon Mac with M1 processor with physical iPhone devices, but, it refuse to be compiled for iOS simulator.

Without simulator support, debugging turn around time gets gets really long so I am trying to solve this issue. Not to mention Xcode preview feature isn't working either which is annoying.

The first error that I encountered without making any changes (but moved from Intel Mac to M1 Mac) is like below.

building for iOS Simulator, but linking in dylib built for iOS, file '/Users/andy/workspace/app/Pods/GoogleWebRTC/Frameworks/frameworks/WebRTC.framework/WebRTC' for architecture arm64

The Cocoapods library that I am using is GoogleWebRTC, and according to its doc, arm64 should be supported so I am baffled why above error is getting thrown. As I have said before, it compiles fine in real device which I believe is running on arm64.

According to the doc..

This pod contains the WebRTC iOS SDK in binary form. It is a dynamic library that contains the armv7, arm64 and x86_64 slices. Bitcode is not supported. Our currently provided API’s are Objective C only.

I searched online and it appears there appears to be 2 workarounds for this issue.

The first one is by adding arm64 to Excluded Architectures
The second option is to mark Build Active Architecture Only for Release build.

I don't exactly understand if above are necessary even when I am compiling my app on M1 Mac which is running under arm64 architecture, because the solution seems to be applicable only for for Intel Mac which does not support arm64 simulator, as for Intel Mac, simulators might have been running in x86_64, not with arm64, so solution #1 is not applicable in my case.

When I adapt the second change only, nothing really changes and the same error is thrown.

When I make both changes and tried building, I now get the following 2nd error during build. (not really 100% sure if I solved the 1st error / I might have introduced 2nd error in addition to 1st by adapting two changes)

Could not find module 'Lottie' for target 'x86_64-apple-ios-simulator'; found: arm64, arm64-apple-ios-simulator

The second library that I am using is lottie-ios and I am pulling this in with a swift package manager. I guess what is happening is that because I excluded arm64 in build setting for iOS simulator, Xcode is attempting to run my app in x86_64. However, library is not supported running in x86_64 for some reason, and is throwing an error. I don't have much insights into what dictates whether or not library can run in x86_64 or arm64 so I couldn't dig to investigate this issue.

My weak conclusion is that GoogleWebRTC cannot be compiled to run in iOS simulator with arm64 for some reason (unlike what its doc says), and lottie-ios cannot be compiled to run in iOS simulator with x86_64. So I cannot use them both in this case.

Q1. I want to know what kind of changes I can make to resolve this issue...

The app compiles and runs perfectly in both device & simulator when compiled from Intel Mac. The app compiles and runs fine in device when compiled from Apple Silicon Mac. It is just that app refuse to be compiled and run in iOS simulator from Apple Silicon Mac, and I cannot seem to figure out why.

Q2. If there is no solution available, I want to understand why this is happening in the first place.

I really wish not to buy old Intel Mac again just to make things work in simulator.

Answered 2021-Mar-27 at 20:15

Answering my own question in a hope to help others who are having similar problems. (and until a good answer is added from another user)

I found out that GoogleWebRTC actually requires its source to be compiled with x64 based on its source depo.

For builds targeting iOS devices, this should be set to either "arm" or "arm64", depending on the architecture of the device. For builds to run in the simulator, this should be set to "x64".

https://webrtc.github.io/webrtc-org/native-code/ios/

This must be why I was getting the following error.

building for iOS Simulator, but linking in dylib built for iOS, file '/Users/andy/workspace/app/Pods/GoogleWebRTC/Frameworks/frameworks/WebRTC.framework/WebRTC' for architecture arm64

Please correct me if I am wrong, but by default, it seems that Xcode running in Apple M1 silicon seems to launch iOS simulator with arm arch type. Since my app did run fine on simulators in Intel Mac, I did the following as a workaround for now.

Quit Xcode.
Go to Finder and open Application Folder.
Right click on Xcode application, select Get Info
In the "Xcode Info Window" check on Open using Rosetta.
Open Xcode and try running again.

That was all I needed to do to make my app, which relies on a library that is not yet fully supported on arm simulator, work again. (I believe launching Xcode in Rosetta mode runs simulator in x86 as well..?? which explains why things are working after making the above change)

A lot of online sources (often posted before M1 Mac launch on Nov/2020) talks about "add arm64 to Excluded Architectures", but that solution seems to be only applicable to Intel Mac, and not M1 Mac, as I did not need to make that change to make things work again.

Of course, running Xcode in Rosetta mode is not a permanent solution, and Xcode slows down lil bit, but it is an interim solution that gets things going in case one of libraries that you are using is not runnable in arm64 simulator.. yet.

ANSWER

Answered 2021-Jun-10 at 22:05

The master branch of rfigshare seems to be out of sink with what figshare now offers in that the master branch seems to use v1 of the api along with oauth v1 authentication whereas figshare has moved on with v2 of the api and now promotes the use of oauth v2.

While I am unsure whether figshare has shutdown v1 of the api and/or has disallowed oauth v1, it seems like you might still be able to use the package if you install from the sckott branch and use a personal access token (PAT).

To generate a PAT, navigate to https://figshare.com/account/applications in a web browser. At the bottom of this page, you can generate a PAT. When the token is presented, copy it as you will not be able to view it again (although you can easily generate a new one at any time).

You will want to store this token in your .Renviron file. The usethis package has a nifty edit_r_environ() function to make this a little easier:

CMake No rule to make target

Asked 2021-Jun-07 at 01:45

I'm trying to build ORB_SLAM2 on macOS 11.4 with clang 12 and OpenCV4 and have run into this error:

make[2]: *** No rule to make target `/usr/lib/libz.dylib', needed by `../lib/libORB_SLAM2.dylib'. Stop.

This file does not exist on my Mac and I cannot add this symlink due to macOS's SIP. The correct path should be /usr/local/opt/zlib/lib/libz.dylib

How can I fix this /usr/lib/libz.dylib reference?

Here is my branch with my macOS build changes.

I've tried to fix the problem by:

Inspecting each of the project's direct dependencies with otool -L and rebuilt from source where necessary (such as OpenCV) to make sure /usr/lib/libz.dylib is not referenced (fix suggested here)
Using CMake's FindZLIB.cmake module in the ORB_SLAM2 CMakeLists.txt to ensure the correct ZLIB is found

Below is the output showing ZLIB is found but still no luck:

As you found, this function is defined in the libcrypto library, but you did not actually link with that library. You need to add -lcrypto to the end of your linker command line.

The -L option specifies a directory to be searched for libraries requested with -l options, but does not itself add any libraries to the link.

ANSWER

Answered 2021-Jun-03 at 05:53

Your image size is 2x2 and the image format is RGB. Therefore the length of a line is 6 bytes. By default OpenGL assumes that the start of each row of an image is aligned to 4 bytes.

This is because the GL_UNPACK_ALIGNMENT parameter by default is 4. Since the image has 3 color channels (GL_RGB), and is tightly packed the size of a row of the image may not be aligned to 4 bytes.
When a RGB image with 3 color channels is loaded to a texture object and 3*width is not divisible by 4, GL_UNPACK_ALIGNMENT has to be set to 1, before specifying the texture image with glTexImage2D:
