Building calibre for Windows

shizhihai · 12-10-2021, 12:10 PM

I modified some of the Calibre code and wanted to build it for Windows.
I read the build instructions on Github and realized that I couldn't meet his requirements. After I checked the forum posts, SOMEONE mentioned that you could compile Python files into PyC and replace the contents of Pylib.zip,But I found that this file is not in the latest version.But after I translated git history, I found that after 5.1, the build was changed to directly add pyC files in binary to python-lib.bypy.frozen.

I wonder if there is a way to generate the python-lib.bypy.frozen file without recompiling all the dependencies (only the modified Python files).
Or how to replace pyc files stored in python-lib.bypy.frozen with your own compiled pyC files.

You dont need to do any of that, just set a single environment variable. https://manual.calibre-ebook.com/develop.html

Thank you for your reply.
I have read the document and set the environment variables on my computer. The modified code runs well on the computer.
However, I want to build my own installer by modifying the python-lib.bypy.frozen method so that I can install and use it on other computers without having to re-download the source code setting variables.
I was also aware of Calibre-Web services, but it didn't do a good job (we had a multi-layer nested Intranet)

No, there is no way to do that If you want to build calibre installers yourself, you have to do the entire build.
