Having trouble building cygwin1.dll from source

Having trouble building cygwin1.dll from source

[Ray Bryant]

I downloaded cygwin-1.1.8-2-src.tar.gz, untar'd it, ran configure in the top
level directory, then typed "make all".  After populating the i686-pc-cygwin
directories and the like, that make failed with "no rule to make "all" in
i686_pc_cygwin/winsup/cygwin.  Turns out that there was no Makefile there;
fixed that by running configure in $TOP/winsup/cygwin and symbolically
linking the resulting makefile down to i686-pc-cygwin/winsup/cygwin.  On the
next "make all", the build failed with a missing libc.a and libm.a in
newlib.  But it did make a libcygwin.a and since these other files are
symbolic links to libcygwin.a I placed symbolic links in the appropriate
places in newlib and tried again.  

I am now getting the following output, which has me completely stumped
(sorry about the ugly line splits):

Any suggestions on how to fix this?  Thanks.

Never(!) build Cygwin in the source dir. Create a new dir for example
parallel to the top level source dir, cd into it and call configure:

	cd <toplevelsourcedir>
	cd ..
	mkdir bin
	cd bin
	../<toplevelsourcedir>/configure
	make

Nor should there be a Makefile there.  You seem to be missing some understanding
about how this is all done.

Check out the "Contributing" link on the Cygwin web page for some clues.

Corinna,

Ah... That works...  Thanks for the tip.  I guess I'm used to building Linux
kernels and expected the build to work inside of the src tree.
