Hi, folks. I want to call a #define FUNCTION() in objc header file from kotlin code, how should i do to cinterop it to kotlin klib?

[xiaobailong24]

Find this:
https://kotlinlang.org/docs/native-c-interop.html#macros

[xiaobailong24]

#define RCT_EXPORT_MODULE(js_name) \
RCT_EXTERN void RCTRegisterModule(Class); \
+ (NSString *)moduleName{ return @#js_name; } \
+ (void)mrn_moduleRegister {  \
KLN_METHODS_EXPORT(kMRNReactNativeModuleRegisterKey);  \
RCTRegisterModule(self);  \
}

.def looks like:

language = Objective-C
headers = RCTBridgeModule.h RCTBridge.h
headerFilter = RCTBridgeModule.h RCTBridge.h

---

static inline void rctExportModule(NSString* str) {
    RCT_EXPORT_MODULE(str);
}

Then got this error:

Exception in thread "main" java.lang.Error: /var/folders/r1/ph4mc_993nqbc_v5m82d0rv80000gp/T/8166082263048599838.m:5:5: error: use of undeclared identifier 'moduleName'

Did you ever get this figured out? Trying to do the same thing...
