but it didn't seem to make any difference. The resulting smbclient was still dynamically linked.
I found a previous post which led me to try adding:
But that also didn't seem to make any difference.
I can verify by inspecting config.log that the options are being passed in. But I'm not sure why they're having no effect. Here is the complete options listed in config.log:
