Build Fails: "Use of undeclared identifier 'nullptr'" #56

Open userFortyTwo opened 5 months ago

userFortyTwo commented 5 months ago

Building an app with the geopackage-ios pod added to it fails on my M2 Mac (running macOS 14.4.1).

Version Information:

Expected Results:

The build should succeed, and the app should launch in the simulator.

Observed Results:

The build fails.

Output:

sf-proj-ios

Steps to Reproduce:

  1. Create a new Xcode project for an iOS app.
  2. Run pod init.
  3. Add pod geopackage-ios, '~> 8.0.6' to the Podfile.
  4. Run pod install.
  5. Open the newly created Xcode workspace and hit Run.

Relevant Code:

none

Test Files:

none

Additional Information:

The C++ Language Dialect is set to the default GNU++20 option in the build settings and thus should support the nullptr literal.

Manually defining the nullptr keyword inside the optargpm.h file (#define nullptr 0x0) resolves the problem, but leads to further compilation issues. In this case, an error message is received, saying the memory file included at Pods/PROJ/filemanager.hpp:31 could not be found. Commenting out this include-directive, the compiler will complain about the string file missing, which is included in the next line.

These issues might result from the fact that the C++ headers may be interpreted as C code. (Editing the headers to emit #error C code on #ifndef __cplusplus appears to confirm this assumption.)

Is this a bug? Is anyone else experiencing these problems, or does anyone know how to solve them?

I have encountered the same issue, are there any updates concerning this issue?

callmeahab commented 4 months ago

I resolved this issue by adding swift bridging header and also had to set User Script Sandboxing to NO in the project settings.

@callmeahab I have the same problem, can you share the content of the bridging header you added please ?

callmeahab commented 4 months ago

Sure, just create a file somewhere in your project

#ifndef <AppName>_Bridging_Header_h
#define <AppName>_Bridging_Header_h

#import "geopackage-ios-Bridging-Header.h"

#endif /* <AppName>_Bridging_Header_h */

somewhere in your project (replace with your application name).

Go to your project settings and set Targets -> YourProject -> Build Settings -> Objective-C Bridging Header and set the value wherever you saved the file.

Also set User Script Sandboxing to NO on that same page.

@callmeahab Thank you for you answer, I don't have this error anymore after adding a bridging header, but now I have this :

Pods/PROJ/src/apps/proj.cpp:13:10 'crs.hpp' file not found with include; use "quotes" instead

Did you have the same problem ?

callmeahab commented 3 months ago

Not after configuring the bridging header
