Op 25-04-2024 om 16:58 schreef Stefan Behnel:> If it's a somewhat
straightforward change that doesn't need tons of
back-and-forth testing and debugging, and you have a github account, you
could also use their CI service (Github Actions), either on your own
account or in lxml's account via a pull request.
That would be an interesting approach (I do have a github account). I
have looked at the actions to see if they would help me figure out how
to build lxml, but what it does is beyond me, I'm afraid. If I could
fork lxml, experiment, and have an action build it for me, I'd be very
happy. 🙂 I'm not sure how to go about that, though.
It might help to see the command line.
For completeness, I've included everything I did below (it isn't
actually that much). It wraps, which doesn't help readability, but I
don't know how to stop Thunderbird doing that. (Is attaching a text file
allowed on the list? Perhaps that would work better.)
As you can see below, compiling seems to work fine, but linking fails.
At least the first two symbols _xmlStrchr and _xmlIOParseDTD, can be
found within libxml2_a.lib, but without the underscore. Does this mean
the libraries are perhaps compiled with differerent flags?
Thanks for your help, kind regards,
Gertjan.
