Seg Fault

[7Towers]

I'm seeing a seg fault on OSX (Sonoma 14.6.1, M3) and Windows 11 with the most basic of implementations.

Is this a known issue?

[galkahana]

you provided a folder path instead of a file path. try providing a file path instead. should work better. note that you can get some help with:

• tracking status along the way. StartPDF already fails
• setting up log output. this would create a log file that sais something like: "[ 17/08/2024 18:00:30 ] OutputFile::OpenFile, Unexpected Failure. Cannot open file for writing - D:\mylib\tmp" which would make sense, given one can open a directory an file handle to write to. D:\mylib\tmp\a_file.pdf would work better.

Thanks @galkahana Providing the file path resolves the issue. Well done. Solid library. Thanks for your work.
