Xcode in macox 10.15 beta library code signature problem #15645

CaffeCat · 2019-10-05T10:26:14Z

This is the first time to use opencv at Mac OS. I used homebrew to install opencv in my Macbook, and all path search definitely correct in Xcode. I created a hello world in commandline tool project using C++ language not OBJC language. I could compile my opencv hello world, but it was broken in runtime, with showing the following logs:
=== logs ====
dyld: Library not loaded: /usr/local/opt/opencv/lib/libopencv_flann.4.1.dylib
Referenced from: /Users/weibinwu/Library/Developer/Xcode/DerivedData/OpenCV-frdcgrfkxsvbyahjaonnyllerinn/Build/Products/Debug/OpenCV
Reason: no suitable image found. Did find:

== logs ===

please could somebody help me out of this problem?

I still waiting for your help, and really get confused on code signature >V<

alalek · 2019-10-05T15:41:22Z

macox 10.15 beta

Probably no support for that yet (we don't have these configurations).

/usr/local/Cellar/
homebrew

It is better to ask there about MacOSX signing issues. Or check Apple forums about 10.15 beta signatures.

@CaffeCat I met same problem, and solved it using code sign
I just codesign all errors.
codesign -f -s "Mac Developer: YOURDEVELOPEREMAIL" /usr/local/opt/*/lib/*.dylib

CaffeCat · 2019-10-08T01:53:38Z

@LeeGwangYong Thanks a lot! I will try after work.

CaffeCat · 2019-10-08T14:24:41Z

@LeeGwangYong You are exactly right!!! It is useful to use your recommended command to code sign every error dylib file!

vivek-ram · 2019-11-10T12:29:55Z

@LeeGwangYong hi bro i also have same problem but codesign -f -s "Mac Developer: YOURDEVELOPEREMAIL" /usr/local/opt//lib/.dylib is not working it is saying Mac developer not found can you please help me

pedrofrodenas · 2019-11-10T20:06:51Z

I have the same problem, I can compile opencv 4 project but when it comes to execute it throws those errors.
Executing this not solves the error
codesign -f -s "Mac Developer: MYDEVELOPEREMAIL" /usr/local/opt//lib/.dylib

Mac Developer: MYDEVELOPEREMAIL: no identity found

vivek-ram · 2019-11-11T09:38:59Z

@pedrofrodenas yeah exactly I don't know what to do. have you solved that error?

pedrofrodenas · 2019-11-15T16:59:53Z

@pedrofrodenas yeah exactly I don't know what to do. have you solved that error?

Hey,
I have the same problem with Vulkan.
I solved this by checking this box:

Meriky · 2019-12-18T16:27:21Z

I have this problem too, but I don't have a developer account
and I finally solved this by removing the default git of mac and using git from homebrew

#remove /usr/bin/git
brew install git

jimgeldermann · 2020-02-01T19:20:47Z

Thanks - same problem with custom frameworks after I upgraded to Catalina. "Disable Library Validation" fixed the problem. xCode Version 11.2.1 (11B500)

Hey, I don't have this option :/ Know why?

EDIT: Nevermind! I found it. I had to enable hardened runtime under Build Settings.

KangWeon · 2020-03-10T19:41:04Z

codesign -f -s "Mac Developer: YOURDEVELOPEREMAIL" /usr/local/opt//lib/.dylib

when running above, if it would be error, replace "YOURDEVELOPEREMAIL" by "YOUR TEAM NAME".

Thanks. This helped me.
But in my case (macOS 10.14.6, Xcode 11.3.1), I had to use the identity found in keychain which happens to be like this "Apple Development: Firstname Surname (xxxxxxxxxx)".

Thanks u. bro

I have the same problem on Xcode 11.4.1. ran the command "codesign -f -s "Mac Developer:" getting no identity error. I don't see the option of Disable Library validation on Xcode 11.4.1

Please use command security find-identity to find out the exact one's own identity.

StevenACoffman · 2021-07-10T01:49:18Z

If you are developing or compiling the binaries yourself, you can generate a self-signed certificate by accessing Keychain Access > Certificate Assistant > Create Certificate -> Certificate Type: Code Signing. You can then sign your binary with:

codesign -f --sign <Name of certificate created above> /usr/local/opt/*/lib/*.dylib

However, I don't think that these will work unless you have an Apple Developer account.
