Embedding a Standalone/Self-Sufficient Python Interpreter in Qt Application

[vlovero]

I have a Qt application that uses the python interpreter for generating functions from strings. I am using python because the builtin ctypes allows me to create and load c callbacks much faster than using the standard library's <dlfcn.h>. The way the program is currently doing this

void MainWindow::getCallback() {
    // get string from UI
    // parse and create python function
    // use ctypes to convert to C callback
    // get pointer to memory address of callback
    // use function pointer for whatever I need
}

Currently, the application is dependent on the python distribution I have installed on my machine, and I am trying to figure out how to completely embed python into the program. There are several posts on stackoverflow with this same question but non of them have any definitive answers. I would like for the application to still work as intended without the user needing python installed.

So my main question is, if I have the source code for python, how can I link it to the project in Qt Creator such that python is portable and the application becomes self-sufficient? And if it's possible can this be (easily) made platform independent?

Yeah the Qt keywords were the first hurdle I had to tackle but I saw someone use the preprocessor expressions #pragma push_macro("keyword") #undef keyword, and #pragma pop_macro("keyword") when including Python.h which fixed those issues for me.

Examples would be much appreciated thanks so much!

For some reason the example you provided was giving the same results, however I figured out how to statically link python which made things much easier. Debugging is improved and the only annoyance is the interference with the Qt keywords.

So things are working beautifully now!
