    @vinaygopal said in embed a python function into my Qt App.:

    "the code model could not parse an input file,which might lead to incorrect code completion"

    You can ignore this.

    Can you show the exact linker error?

        @vinaygopal This is not linker error but compiler.
        Try to include the header like this:

        extern "C"
        {
          #include <Python.h>
        }

                @vinaygopal On Windows it should be:

                LIBS += $$PWD/../../../AppData/Local/Programs/Python/Python37-32/libs/python37.lib

                  @jsulm i did add the library as you had recomended it still did'nt work and more importantly i figured the module python.h and its equivalent library is not compatible with mingw gcc compiler it is only compatible with microsoft specific compilers as suggested by this question (https://stackoverflow.com/questions/6731100/link-to-python-with-mingw) they have provided an answer but is there a simpler way to get this done?

                    @vinaygopal One question: do you build your app as 64bit? Your Python seems to be 32bit.

                        Yes, you can't mix 32bit and 64bit

                            @vinaygopal Can you show your current pro file?
                            Also did you a clean rebuild?

                                I'm keeping an eye on this thread. As I said right at the start

                                You can indeed go down @jsulm's path, but embedding is a lot more involved than just running a subprocess.
                                But as phrased if all you want to do is run an external script with some command-line arguments [...], it really is simple to do with QProcess, should take one minute to write.

                                I do hope/presume that (for both your sakes) for use case here all this embedding is indeed required and worth the effort! :)

                                  @vinaygopal Looks correct to me. I would try this:

                                  • Delete build directory
                                  • Run qmake
                                  • build

                                    When i click a button, i want to open up the python script (.py file) and run the python script written by me and exit python. I should be able to pass arguments to the python file through Qt c++? please help me out on how to achieve this. i did do some reading about QProcess class but i am not able to achieve this.

                                    @vinaygopal how dead set are you on Python as the scripting language?

                                    If it's not dictated and just a random selection, I'll want to offer 2 alternatives

                                      @vinaygopal said in embed a python function into my Qt App.:

I should be able to pass arguments to the python file through Qt c++? please help me out on how to achieve this. i did do some reading about QProcess class but i am not able to achieve this.

                                      If that is indeed all he wants to do, he may not need any integrated scripting, he may just need to make his QProcess attempt work and we would be done....

                                      If he would say why/what the script is supposed to do which requires embedding, we would all know what is required....

                                        I'm keeping an eye on this thread. As I said right at the start

                                        You can indeed go down @jsulm's path, but embedding is a lot more involved than just running a subprocess.
                                        But as phrased if all you want to do is run an external script with some command-line arguments [...], it really is simple to do with QProcess, should take one minute to write.

                                        I do hope/presume that (for both your sakes) for use case here all this embedding is indeed required and worth the effort! :)

                                        @JonB @jsulm @J-Hilk ok alright! i give up on embedding python into my program! it just doesn't seem to work however this is the reason for me to use Python, i have a file in my local desktop and i have to send it to the cloud and make the image uploaded a public image these cases can be easily achieved using python if i have to do it with javascript i will have to do it using node JS which will complicate the app, so from QProcess i am able to open the python file inside the python file i have a function called upload blob and it takes two arguments how do i call this function blob and pass those 2 arguments to them using QProcess().

                                        My C++ code

                                          Which is why I asked as I did at the start! Really wish you had said!

                                          So you simply want to pass some string filenames to a script which does something, right? No need for integrated scripting.

                                          You need to tell us what actually happens/goes wrong!

                                          First just make your Python script print out everything in sys.argv so we can see.

                                          Oh, I see, you haven't twigged that at all. You can't just write a function in a standalone Python script/program. You need to have a main program in your script, and access argv for the command-line arguments!

                                          import sys
                                          # Main entry point of app
                                          if __name__ == "__main__":
                                              # args = sys.argv
                                              # count = len(sys.argv)
                                              while i < len(sys.argv):
                                                  arg = sys.argv[i]
                                                  print(arg)
                                          

                                          There are millions of examples on the web.

                                          Separately, you'd better hope all your commands etc are happy with those / path separators rather than native \. I don't want to debate this again with others: some Windows stuff is happy with /, some is not.
