Examples fail to link about cpp-reflection

[ArnauPrat]

Hi again @AustinBrunkhorst
My five cents on my investigation. IF I comment out this if-else statement (from 132 to 138), everything goes well. I understandy that this code basically creates the empty generated files. Then, when building with make, since it already finds these files available (though empty), it does not trigger the command to generate them. Does this make sense?
Thanks
Arnau

Hello there!

It does look like the pre-build parser step is not being run, which would cause the linker errors. Just to confirm, is there Parsing reflection data for target "..." anywhere in the output?

Also, are you using the cmake --build command?

Hi again!
No *Parsing reflection data for target "..." * in the output
I tried with both cmake --build . and direclty calling make, with the same outcome.
This is the output of calling cat ./* inside the Generated folder:

 cat ./*
/home/aprat/projects/personal/owc/lib/reflection/Source/Runtime
/home/aprat/projects/personal/owc/lib/reflection/Source/Runtime/..
/home/aprat/projects/personal/owc/lib/reflection/Source/Runtime/../Common/Lib

ls ./* shows the following:

Module.TestModule.Generated.cpp  TestProperties.Generated.cpp  TestTypes.Generated.cpp
Module.TestModule.Includes.txt   TestProperties.Generated.h    TestTypes.Generated.h

As you can see, files are empty. I'll try to investigate why the Parser is not being executed.
Thanks for your help

@ArnauPrat This does make sense.

CMake requires files to exist in order to be included in a list of sources, so writing the files was necessary before calling add_executable or add_library. I have since completely re-written the entire pipeline - among the changes was a great suggestion from @l0calh05t here which makes use of the GENERATED source file property, which allows sources to not exist.

I'm pretty sure writing empty files in meta_parser_build is just me forgetting to remove it after the refactor. I will test removing it!

Thank you for taking the time to investigate this.

Cheers

@AustinBrunkhorst Hi
when I build the Examples,it show me the message "error MSB6006: “cmd.exe” exited with code -1073741819" after Parsing reflection data for target "..." in the output.
So,I tried ro debug the Parser,it show me the message "access violation executing location ..." when call the "clang_Cursor_getStorageClass(child)" form some Cursor.
I am under Win10 x64, using Cmake3.14.4, VS2015, libclang 3.8.0 and boost 1.59.1
Best,
Aaron.

Sorry for the inactivity here folks. I'll get back to these issues in the near months, but plan to facilitate any pull requests if that is something that anyone is interested in!

Thanks.
