Embedded python issues

[jonsy11]

Hello all,

I would like to modify the QT software, but I've been struggling to build it due to issues with the files with embedded python. I switched all the directories in the .pro file to my own, shown below, and I don't get any errors that the header cannot be found, but none of the python included function references are said to be defined. I know in 3.8 that I have to specify to GCC that I want to use the embedded config of python, but that doesn't seem to be a thing in 3.7. Any ideas on what's happening?

Below is my project file:

Thanks, Ian

Unfortunately I am no expert when it comes to compiling with embedded QT (I was a bit surprised I was able to get it to work myself in the first place). Have you placed the python dll in the folder containing the compiled software?

I tried that this morning and was met with no changes. After more digging, I came to wonder if I was just using a different compiler than you. I switched to mingw 64 bit from 32 bit and it worked. Thanks for the suggestions. Now I'm off to go build opencv and pray that everything compiles after!
