Errors in main.mm file : Use of undeclared identifier

[royken]

Hello,
thank you for this tutorial. Followed all the steps, but in the main.mm file i have the following
errors: (screen the image bellow)

• use of undeclared identifier 'UnityParseCommandLine'
• use of undeclared identifier 'nil'
• use of undefined identifier 'NSLog'
  
  Sorry for the image quality

This is the file content:
`#include "RegisterMonoModules.h"
#include "RegisterFeatures.h"
#include

// Hack to work around iOS SDK 4.3 linker problem
// we need at least one __TEXT, __const section entry in main application .o files
// to get this section emitted at right time and so avoid LC_ENCRYPTION_INFO size miscalculation
static const int constsection = 0;

void UnityInitTrampoline();

// WARNING: this MUST be c decl (NSString ctor will be called after +load, so we cant really change its value)
const char* AppControllerClassName = "AppDelegate";

int main(int argc, char* argv[])
{
@autoreleasepool
{
UnityInitTrampoline();
UnityParseCommandLine(argc, argv);

    RegisterMonoModules();
    NSLog(@"-> registered mono modules %p\n", &constsection);
    RegisterFeatures();
    
    // iOS terminates open sockets when an application enters background mode.
    // The next write to any of such socket causes SIGPIPE signal being raised,
    // even if the request has been done from scripting side. This disables the
    // signal and allows Mono to throw a proper C# exception.
    std::signal(SIGPIPE, SIG_IGN);
    
    UIApplicationMain(argc, argv, nil, [NSString stringWithUTF8String:AppControllerClassName]);
}

return 0;

In your screenshot, there are two Data directories listed under Unity group. There should only be one Data directory there. Guess you dragged Data instead of Classes by mistake.

Thank you @yasirkula !!!

Hi guys,

I have kind of similar problem.

I followed the tutorial but I this error 'use of undeclared identifier' on UnityInitStartupTime(); and UnityInitRuntime(argc, argv);

[yasirkula]

Can you show the contents of the Unity group in Xcode?

[scarffy]

Here it is.

[yasirkula]

If you are trying to test the app on a simulator, can you also try to test it on a real device and see if it changes anything? Unity produces slightly different output for simulators (see Target SDK/SDK Version), so it might be the issue here. Otherwise, if you have made all the adjustments to both PROJECT and TARGETS in Build Settings correctly, I couldn't spot the issue at first glance.

[scarffy]

Unfortunately, the error doesn't go away when I try to test it on a real device. :(

[yasirkula]

If you are sure that you have set all the configurations to unityconfig and that you have set the value of UNITY_IOS_EXPORTED_PATH to the path of your Unity build directory (not the one in the screenshot) for both PROJECT and TARGETS, then I guess any help is welcome at this point.

[scarffy]

I am quite sure I set up this properly. Here's my screenshot of UNITY_IOS_EXPORTED_PATH and also in config

[yasirkula]

Can you show the contents of /Users/Scarffy/Desktop/iOSNativeApp, as well? Just to be sure, if it is OK.

[scarffy]

Here you go.

Edit : I'm using unity 2017.3.1 but UNITY_RUNTIME_VERSION says 5.5.2f1. Does it have an effect on this?
