i got same issue on ubuntu

[Yi-Lynn]

Hi, I met the same problem, have you solved it yet? Thanks!!

[CodeGeek04]

In my case, there were some issues with cmake. I got some warnings, and I focused on solving them first. Once I fixed all warnings, the library got installed without any issues

@CodeGeek04 Hi, May I ask what warnings you got and how you solved them? I'd really appreciate it if you could provide any details.

[CodeGeek04]

If you are getting the same exact error, then their might be a warning just above the Trace Stack. On time it was regarding nvidia cuda toolkit incompatibility, so I had to reinstall it. I dont remember other warnings. However if you see any such issues, above trace stack, you can share them here and I'll try to remember the soution

Thank you @CodeGeek04. I had the same issue as @RomanticGodVAN, related to the PYTHONLIB not being found, as shown below. Fortunately, I just solved this problem by cleaning and deleting the whole diffvg folder from my project and git clone it again.

I spent days and nights to complete the diffvg compilation on Windows. If anyone wants the wheels, you can contact me +V13862010554. Let's create a group to communicate and exchange about the improvements based on the module together.

[benbaker76]

You can check out my fork which has instructions on how to create the wheel and install on Windows.

Just add the following line to the setup.py script:

diffvg/setup.py

Lines 38 to 40 in 85802a7

	cmake_args = ['-DCMAKE_LIBRARY_OUTPUT_DIRECTORY=' + extdir,
	'-DPYTHON_LIBRARY=' + get_config_var('LIBDIR'),
	'-DPYTHON_INCLUDE_PATH=' + include_path]

cmake_args = ['-DCMAKE_LIBRARY_OUTPUT_DIRECTORY=' + extdir,
                        '-DPYTHON_LIBRARY=' + get_config_var('LIBDIR'),
                        '-DPYTHON_INCLUDE_PATH=' + include_path, #   <--- here
                        '-DPYTHON_INCLUDE_DIR=' + include_path]
