Cannot compile AC26 addon for AC27

[YourQS]

I have a plugin that compiles and works fine in AC26.   I am upgrading it to AC27.   I have installed the AC27 API kit and changed all references in the project file to the 27.3001 folder.

I now get about 6000 errors, many of them like these:

Code: 

CParameter* Factory(const API_AddParType &parameter);

Errors:

Error C4430 missing type specifier - int assumed. Note: C++ does not support default-int
Error C2143 syntax error: missing ',' before '&'

The Visual Studio IDE is able to identify the type API_AddParType and can navigate to the .h file if I press F12 on the type, but the compiler doesn't seem to be able to find it. (See attached image)

Could someone help with what I need to change to resolve this issue?

Did you specify C++17 for your Project when compiling for AC27? The AC27 DevKit assumes the use of C++17.

Hi Bernd, yes I had already set C++17 as the language standard, thanks, but that did not resolve these issues.

Hm.. I took a closer look. API_AddParType is defined for the AC27 DevKit. But CParameter is not.

In fact, when I copy your code line into one of my projects, I get the exact same errors and Visual Studio highlights CParameter as missing. So I think it's very likely that somehow you are not properly including the headers which define CParameter. Where do you get this type from?

Best,

Hi Bernd,

It is one of our own classes defined in Parameter.hpp, which is included in the file. here is a large snippet showing the original code and  the include.   What is peculiar is that the VS IDE happily identifies CParameter, (no red squiggle) and I can navigate to it by pressing F12 on it in the IDE

Hi Nick,

It's a tough one. I don't see anything obviously wrong with the code.

A few questions:

• Where is the file Parameter.hpp located? I'm wondering why you are including it with angle brackets instead of quotes.
• Can you show the definition of CParameter? (Please use the function "Insert/Edit code sample" on here for better formatting of code)
• Can you prepare a minimal example project without proprietary code where the compilation still fails? Ideally just CParameter definition + a file where it's included + the project definition. This might be a lot of work, but might help you debugging the issue and if you have a small example, you might be able to share it with us for us to investigate.

Best,
Bernd
