> Hum, do you have aclocal.m4 in lyx root directory?
nope (acinclude.m4 i have though).
I see, you don't have the aclocal (perl) program. Weird because this is
supposed to be part of the automake package. Try to see in the cygwin
installer if you can find it. I'll attach it nonetheless. Make a simlink
to it. I told you it would be easier to use my cygwin package ;-)
isn't autogen.sh supposed to create aclocal.m4?
Yes I think so.
putting the one you send me there doesn't make a difference though...
