Re: [libmicrohttpd] Build issue on MINGW

[Christian Grothoff]

Hi Tim,

The issue is that in line Makefile.am:10, we have "noinst_" instead of
"lib_" because the code is far from complete and it must not yet be
installed. That causes the dlname='' issue you describe.

The best fix I can propose: I'm adding an option (--enable-experimental)
which disables building src/lib/ by default, so that users that don't
care about the experimental code don't get disrupted like this.

Happy hacking!

Christian
