Linux, QtCreator and Qt5.9.6 compiling GNU C Libraries
I have the following problem: I have installed a Modbus slave stack for Linux in my Qt5.9.6 in Ubuntu Linux.
The Modbus slave stack has a pure C source code and mainly accesses GNU C libraries.
Now I have the problem that the Modbus does not work as it should on the Yocto Rocko Linux.
But already in QtCreator on Ubuntu the GNU C libraries are interpreted incorrectly by the code editor and some functions are underlined in red.
For example for the Modbus slave stack the function mq_open from the mqueue.h library is important, but the function mq_open cannot be opened in the code editor and in the header mqueue.h this function mq_open is underlined red in the declaration with the error message: Expecting a declaration.
Therefore my question: How can the GNU C libraries under Linux be correctly interpreted and compiled by the compiler, so that the Modbus stack works again?
The Modbus stack worked with Qt4.72 on the ptx-Linux platform.
Thanks in advance for replies.

Hi @MrNickless, welcome!
From your description, the editor problem sounds again like a Clang Code Model problem. You can try to disable it with Help > About Plugins > Clang Code Model.
That however, is completely unrelated to compile or run problems. Did I get it right that you can compile the code and it runs on the target, but has runtime problems? Which kind of problems?
