Hi All, I am getting below error when trying to build my native c++ plugin in xcode 15.2.

Can anyone please help.

Thanks

In both a reference SDK sample project and your own project, create a shell script build phase that outputs all the environment variables to a file – alternatively there's also a "Show environment variables in build log".

Compare both files.

Some of the differences are random IDs that differ per Xcode run.

Ignore those cases; taking an automated approach I use a sed script to clean them up.

Also offload all build setting overrides within the project into xcconfig files.

I compared build settings with previous 19 SDK proj file and every settings are similiar in 20 SDK proj file but still getting the above errors.

Hmm, did you compare build settings in the IDE (multiple places to cover, easy to miss one) or a dump of the environment variables as I suggested?

Also have a look SDK docs/html/id_porting_guide.html mentions "Other project changes to note"

Watch out for CLANG_CXX_LANGUAGE_STANDARD and BOOST_SPIRIT_THREADSAFE e.g. if you use own xcconfig and bypass common.xcconfig .

I would suggest you first try to build a sample plugin and if that does not build then definitely you have an incorrect setup of dev env. The best way to resolve such an error is to cross check the recommended env in the SDK documentation.

@Manan Joshi thanks for the reply.

The samples plugins are building fine without any errors.

Then we would need to check it from the Boost end maybe. Did you create the lib you are linking against?

@Olivier Beltrami Thanks for reply.

After went to c++14 now I am getting "Use of undeclared identifier 'LONG_LONG_MIN" see screenshot for reference.

What version of C++ were you using for your version 19 plugins ?

Try using the exact same settings as for previous versions.

In previous version 19, I was using GNU++14 [-std=gnu++14]. I tried with it as well in SDK version 20 but still it is giving me previos errors. Attached file for reference.

@Alam5EC6 When the pre-release version 20 SDK came out, there was a lot of mentioning that the version 20 plugins should be compliant with the C++17 standard. I made sure my code was ... but it turned out that the SDK was not ! Are you trying to build using the C++17 standard ? So I went back to C++14 and everything works fine.
