[Git master] Fails to compile on Linux with fatal error: microhttpd.h: No such file or directory

Hi!

This is what I get on Linux with latest master.

Is this a bug in the build system?

Best, Sebastian

Any thoughts?

[smileaf419]

It’s listed as a Networking dependency. https://www.gnu.org/software/libmicrohttpd/

[clangen]

Yeah, libmicrohttpd must be available.

[hartwork]

It seems to compile after installing microhttpd. Any chance to have the build system detect absence of microhttpd and ask to install it?

[clangen]

I just added improved detection for microhttpd during build, this will be fixed in the next release.
