Hi,
This is regarding to DA14695. I have an application written in C++ and driver writen in C for another MCU, now i have port the same application on Dailog MCU environment.
When i try to create a C++ project I'm not able to see the SDK folder as it is available in the built-in examples like ble_adv, ble_cli.
When i take the base project as ble_adv, and try to add my Cpp application, i'm not able to add the cpp files.
请告诉我如何使用Freertos部分创建CPP项目，或者如何修改像BLE_DEV示例等漏油项目。
regards

Hi,
I have escalated this issue to our internal support team. We should receive a reply in the next day or two.

Hi,
我收到了我们内部支持团队的以下提示：
"
In order to get the C++ to coexist peacefully with the C, it is required to have all C header decorated with the following pattern:
"
I hope that helps you resolve the problem.

hi,
The question was regarding to create a projec C++ .
当我们尝试创建一个C ++项目时，我们没有看到像BLE_ADV，BLE_PERITELAL这样的示例项目中看到的任何文件夹。没有看到SDK文件夹。
my requirement is to create a project with FreeRTOS support and the project has C source files as well as C++ source files.
Kindly shared details regarding this. How to create a project for a ble_peripheral with support for FreeRTOS and has C and C++ source files.
regards
嗨Sandeep，
I think the best approach would be to convert an existing project from C nature to C++. There's an integrated tool in Smartsnippets studio. you need to "File->New Project -> Convert to a C/C++ project" and then follow the wizzard.
Then you start to make sure all the headers you include are correctly decorated.
Hi,
The steps mentioned by you work only partially. I have taken a demo project from sdk folder. ble_peripheral. perform clean and build it build successfully.
Now as mentioned by you i try to Open new project and select the option to convert to C/C++ project. In the wizard i can see the ble_peripheral project i select it and select ARM_CROSS_GCC. I have not added any new C++ files yet.
Now again i perform clean and perform build. The build invokes C++ compiler and gives below errors. Kindly advice.

Hi,
Can you guys reply to my query. The cpp file get compiled but there is a linker error. i have shown some of the errors.
have you guys tried conversion of C to C++ for any example code like ble_peripheral, bli_central
Hi,
目前我在链接器设置中进行了一些更改，并将库路径添加到链接器。链接错误减少。
currently i get only two linking error.

请告诉我们如何解决这个问题。
嗨Sandeep，你是否能够在构建CPP应用程序时解决链接器问题？
我面临着同样的问题。编译工作是工作，但链接器缺少大量引用。
Could you please advise?
Thx!
