[michael-mansour]

Describe your environment

• Xcode version: 11.1
• Firebase SDK version: 6.3.0
• Firebase Component: Firestore
• Component version: 1.5.1

Describe the problem

When I archive my project for MacCatalyst I get the following errors:

'openssl_grpc/ssl.h' file not found
'openssl_grpc/bn.h' file not found
'openssl_grpc/rsa.h' file not found
'openssl_grpc/bio.h' file not found

I have no issues when I run the project.

@michael-mansour Thanks for the report

I'm able to reproduce with pod gen FirebaseFirestore.podspec --local-sources=./ --auto-open, updating the signing and archiving App-iOS:

It does seem like the file is there:

More investigation required ....

Created https://github.com/grpc/grpc/issues/20500 on the gRPC repo.

[michael-mansour]

I know that you are working actively on the issue and I wanted to thank you for that. However I really have to ship my app. While waiting to find the source of the problem, would you have any idea of a workaround so that I can still distribute my app ?
Thanks a lot

[paulb777]

@michael-mansour See the discussion at grpc/grpc#20500 for instructions about manually creating a symbolic link to workaround.

[michael-mansour]

@paulb777 thanks ! Unfortunately I am not really familiar with the process of manually adding a symbolic link. Would it be possible to share more details ? (Like a more detailed step by step explanation ?) thanks a lot !

[paulb777]

@michael-mansour Steps listed at grpc/grpc#20500

[appfrilans]

Any progress here? It's been 6 months!

[JuLink]

Is there any news regarding this issue? It's still present with the last version of Xcode (11.4.1).

[EliteTechnicalCare]

Problem still exists in Xcode 12, is there any timeline this will be resolved so I don't have to play Simon says with files like im trying to defuse a bomb.
