STM32CubeIDE cannot find symbols or variables

[Duy Tran]

Hello ST Community,

I am having the following issue with STM32CubeIDE. I am using the NUCLEO-STM32F767ZI kit and the STM32CubeMX to generate the CubeIDE project. My project uses lwip, mbedtls and GCP. I migrate the GCP from the X-CUBE-GCP: https://www.st.com/en/embedded-software/x-cube-gcp.html

When I just run the lwip and mbedtls, I can compile the code and everything runs. When I add the GCP in, the project cannot be compiled because the lwip cannot find some types like nfds_t, socklen_t... although the files can see their included files and I can still use the Open Declaration function. I already added all the include paths. Do you have any ideas what is going on with my STM32CubeIDE? I am using the latest version. Please see part of the build log:

Find the file where those symbols are included and ensure they are #included prior to being used. Solve the first error reported and it usually solves some or all of the following errors in cases like this.

Be aware that #pragma once or include guards may force a specific order they are included.

Hi @TDK​ ,

The files containing the symbols are already included. Actually I solved several errors and more of the same come :(
