Errors running v3.21.5 autogen.sh on Cygwin/Win10

[Davorin Mista]

I made sure to checkout with Unix-style line endings since I'm trying to build it all in the cygwin terminal but I still keep running into errors. Do I need to have a particular version of libtool? It keeps telling me to run autoupdate, which I subsequently did on the command line, but it's still saying it so I'm not sure what to make of that.

Any help is appreciated.

Nevermind, issue resolved - I was able to fix this by downgrading to autoconf 2.69 and reinstalling automake in Cygwin.

Thanks!
