Hi,

My header file has @end; in many places. Below is the build error:

error: extra ';' outside of a function is incompatible with C++98 [-Werror,-Wc++98-compat-extra-semi]

Just wondering if there is any way to work around it.

Thanks!

use -Wno-c++98-compat-extra-semi flag?

@end in Objective-C code never requires a semicolon, so you should be able to remove those semicolons.

Pasing -Wno flags is almost always the wrong answer. Please don't do that, and please don't suggest doing that.

Just remove the ; like the diagnostic says and you should be good.

I see you posted in chromium-dev@ (https://groups.google.com/a/chromium.org/d/msg/chromium-dev/m9QZvJhMCuE/fhMIrgpFBAAJ) that this is a file generated by the Kotlin Multiplatform Library. Your example shows incorrect generated code; @end is never followed by a semicolon.

Please file a bug against the generator in Kotlin Multiplatform Library.
