help with signing documents about podofo HOT 1 CLOSED

Hello. I'm sorry but for signing document the best support I can provide today not looking at podofosign, which is a legacy and unsupported tool, but by pointing you to the new high level signing API with PdfSignerCms, which is very easy to use and powerful. I updated the FAQ, mentioning it, and you can find a lot of examples in the tests.

The new API is available in PoDoFo master HEAD, which is robust as much as the official releases (if not more robust). If you are stick with the 0.10.x releases, then what you were doing is correct and possibly you should look at the old FAQ which has a big focus on signing using the old low level API. So: ensure you create a new PdfSignature, ensuring it has a value object as you were doing (this is not necessary anymore in PoDoFo master HEAD), and ensure you will sign a stream that has the previous PDF content, that is: the same file from which you loaded the document, or a dynamic memory buffer where you previously copied the PDF content (all of these examples are in the old FAQ).

If you have further problems please open a new issue and show some short/standalone code. Don't refer to podofosign, as I don't look at that code.

gcc 8.4 is not supported ( not matching documentation)

Yes, this is a known issue. It broke recently (patch welcome to fix it). I updated the README.

the supplied build files do not check for required libs version.

Yes, correct. Patch welcome to enhance the current situation, wherever possible.
