Issue with REALM_SCHEMA usage

[pduvalla]

I am observing an issue with REALM_SCHEMA usage in Coffee project , details below

SDK: V0.2.0 preview for SDK c++
Ubuntu 20.04
Qt Creator 4.11.1

ISSUE: realm_models.hpp:17:5: error: reference to local variable 'ptr' declared in enclosing lambda expression
macros.hpp:273:5: note: expanded from macro 'REALM_SCHEMA'
macros.hpp:303:26: note: expanded from macro 'DECLARE_REALM_SCHEMA'
realm_models.hpp:17:5: note: 'ptr' declared here
macros.hpp:273:5: note: expanded from macro 'REALM_SCHEMA'

Hi @pduvalla which gcc version are you using?

[pduvalla]

gcc 9.4.0

[leemaguire]

We only support a minimum of GCC 11.

Seeing the following error with gcc 11
In file included from /usr/include/c++/11/bits/stl_algo.h:59,
from /usr/include/c++/11/algorithm:62,

These errors aren't related to Realm, you might need some configuration in your Qt project, maybe this SO post might have some answers for you.

Thanks! fatal error: stdlib.h: No such file or directory is resolved but still seeing ...
realm_models.hpp:17:5: error: reference to local variable 'ptr' declared in enclosing lambda expression
macros.hpp:273:5: note: expanded from macro 'REALM_SCHEMA'
macros.hpp:303:26: note: expanded from macro 'DECLARE_REALM_SCHEMA'

Can you share the build environment used to verify this example , like the QT version, and gcc version etc

[leemaguire]

I verified the example on macOS 13, Qt 6.4.1, and clang 14.0.3

[pduvalla]

@leemaguire , Is there a work around to make it work with
Ubuntu 20.04
Qt Creator 4.11.1
gcc 11 and g++ 11

I see the same error in hello world example too.

Thanks

[leemaguire]

I will have to test it out on Ubuntu 20.04 and get back to you, the minimum Ubuntu version we test on currently is 22.04
