How to connect Qt program with other program at runtime in Raspberry Pi?
-
An motor driver that is written in C ++ but cannot be connected to the Qt. We also talked to the manufacturer, but to no avail. But the Library works in Raspberry Pi and has example. Is there a way for the Qt program to connect and exchange data with the program running the engine library at the same time?Qt program also is running.

Hi,
Something is not clear, you are talking about both a program and a library. Which one is it ?
If there's a library, in which language is the library built ? -
@SGaist Hi,
The motor driver is a library. But I do not know it is written in C or C++. The library does not have the ability to connect to Qt. But the company has put together a sample program that works well with Raspberry Pi with the library. I have a program in Qt and another program in a other environment that runtime to manipulate the parameters of the motor driver(get and send float, int value ). -
@Saeed_Nowroozi You can use that library in your Qt application.
See here for more details: https://doc.qt.io/qt-5/third-party-libraries.html -
@jsulm Hi, Thank you, saved name of drivers are libEposCmd.so.6.6.2.0 and libftd2xx.so.1.4.8 that when I want to add to my project, Qt can not find these libs. When I change them to libEposCmd.so and libftd2xx.so, Qt find them. In exampe https://doc.qt.io/qt-5/third-party-libraries.html The saved extension is *.s.

So, does it work now (I mean: can you use the libs?)? Instead of renaming the libs you can also create symbolic links:
libEposCmd.so --> libEposCmd.so.6.6.2.0 -
@jsulm Just find but do not work. How create me symbolic links(libEposCmd.so --> libEposCmd.so.6.6.2.0)?

Like any other symbolic link (man ln):
ln -s libEposCmd.so.6.6.2.0 libEposCmd.so
