I have a simple use case which compiles fine:
https://github.com/gabyx/ExecutionGraph/blob/c4b1cccfd855d418dfb3fe53b2cc257aaabcbf14/tests/src/main_Factory.cpp#L36

In another target, I am not even using registration, only RTTR_ENABLE(...).
I get some strange errors:

can you make up anything from this? Why does he need rttr::variant::variant<const bool &, bool>

I am nowhere using an rttr::variant

from every type you register (direct or indirect (e.g. as function return value, argument, etc..) a variant creation function will be created (but only for pointer types)
With that functionality it is possible to perform an rttr_cast in an variant.

Regarding your problem: can you please make a simple test case for me? This would help me a lot.

Jeah for sure!, I studied the problem, its kind of strange... (it seems correct..., maybe compiler bug...)
Can you specify the test problem

how do you register indirectly?
something along the line:

rttr::type foo( return rttr::type::get<T>(); )

?

struct point { int x; int y;}
struct foo { point get_point();}
rttr:.registration::class_<foo>("foo").method("bar", &foo::bar);

this will register also the type point (when the code works correct ^^)

Regarding the test case, remove to much code, so that it compiles again. Then copy the code that seem to instantiate the problematic code in a separate TU and compile it. When it fails again, upload it here.

Ok, made it compile removed everything (no rttr includes):
Look at the Standalone compilation below first, I think this described the problem best.

Standalone compilation: (Test.cpp)

#include <rttr/type>
#include <rttr/registration>
struct point { int x; int y;};
struct foo { point get_point();};
rttr::registration::class_<foo>("foo").method("bar", &foo::get_point);

Could it be that class_ results in some stupid macro expansion?, I will try to output the preprocessor... something is fishy here! -> nope its not the problem used #undef class_

I really dont get the error:
A MWE: (here with gcc, same with clang)
Test.cpp:

#include <rttr/registration>
#include <string>
struct point { int x; int y;};
struct foo { point get_point();};
#undef class_
rttr::registration::class_<foo>("foo").method("bar", &foo::get_point);

Test.sh

#!/bin/bash
comp="gcc"
export PATH="/usr/local/opt/$comp/bin:$PATH"
export CC="/usr/local/opt/$comp/bin/gcc-7"
export CXX="/usr/local/opt/$comp/bin/g++-7"
export LDFLAGS="-L/usr/local/opt/$comp/lib/gcc/7 -Wl,-rpath,/usr/local/opt/$comp/lib/gcc/7"
export CPPFLAGS="-I/usr/local/opt/$comp/include -I/usr/local/opt/$comp/include/c++/7.2.0"
export CXXFLAGS="$CPPFLAGS"

${CXX}  -DRTTR_DLL -isystem /usr/local/opt/rttr/include $CPPFLAGS -g -std=c++17 -o Test.cpp.o -c Test.cpp

gives:

Test.cpp:6:33: error: expected unqualified-id before string constant
 rttr::registration::class_<foo>("foo").method("bar", &foo::get_point);
                                 ^~~~~
Test.cpp:6:33: error: expected ')' before string constant

Thas all?? Any clue???

@acki-m : Got it: with the the macro sourounding it works

RTTR_REGISTRATION
{
rttr::registration::class_<foo>("foo").method("bar", &foo::get_point);
}

Makes sense, we need this rttr_auto_register_reflection_function_ defined

ahhh, I just thought you just simplified the test case and has leave out the macro.
It hast nothing to do with the macro itself

You can also not compile this:

std::string("hello");  // error C2059: syntax error: 'string'

without putting it in a function or assigning a value

auto s = std::string("hello"); // Ok

The same like the registration call.
However, registration object is not copy-able, that's why this doesn't work either:

auto foo = rttr::registration::class_<foo>("foo").method("bar", &foo::get_point); // attempting to reference a deleted function

thanks (that was a bit stupid from my side, I though it also works, because you wrote it like so :-))
the initial compilation problem still existed, up to now. The problem is strange, but I refactored my code such that no .mm ObjectiveC codefile (mixing C++) includes <rttr/type>. I could not get away with it. Somehow clang/gcc does not like it. I am wondering if he ObjectiveC stuff dispatches to XCode??? Now, where I am left with only .h/cpp files which have <rttr/type> includes, it works. jeaii 👍
A single include in a .mm file resulted in the above long output of AppMac.mm

Is this now solved for you?

jeah, I think its just when I try to compile .mm files meaning objectiv-c and c++ mixed, we have problems, why I have no clue!
