Hi,

This didn't make it into the patch, obviously.  I was not familiar
with the workbook symlinks.

+Cross building Guile  =====================================================
+
+As of guile-1.5.x, the build process uses compiled C files for
+snarfing, and (indirectly, through libtool) for linking, and uses the
+guile executable for generating documentation.
+
+When cross building guile, you first need to configure, build and
+install guile for your build host.
+
+Then, you may configure guile for cross building, eg:
+
+    ./configure --host=i686-pc-cygwin --disable-shared
+
+Two special options for cross building are available:
+
+--with-cc-for-build      --- native C compiler, to be used during build
+                             defaults to: `PATH=/usr/bin:$PATH cc'
+
+--with-guile-for-build   --- native C compiler, to be used during build
+                             defaults to: `guile', assuming you just
+                             installed this guile natively.
+
+
 Using Guile Without Installing It =========================================
 
 If you want to run Guile without installing it, set the environment

Hi,

Today I spent making a fresh Guile patch to get it compiled for
Cygwin, and to fix cross building issues that were introduced during
Guile's 1.5 development cycle.

It's against latest 1.6 CVS, making use of autoconf, automake, and
libtool from CVS, that are supposed to have fresh fixes for Cygwin.

I still can't get the shared version to link:

    /bin/sh ../libtool --mode=link gcc -I/home/cygwin/cygwin-1.3.10/usr/include -L/home/cygwin/cygwin-1.3.10/usr/lib -L/home/cygwin/cygwin-1.3.10/usr/lib/w32api -L/home/cygwin/cygwin-1.3.10/usr/bin  -O2 -g -Wall -Wmissing-prototypes   -o guile.exe -dlpreopen force guile.o libguile.la -lm 
libtool: link: not configured to extract global symbols from dlpreopened files
    gcc -I/home/cygwin/cygwin-1.3.10/usr/include -O2 -g -Wall -Wmissing-prototypes -o guile.exe guile.o  -L/home/cygwin/cygwin-1.3.10/usr/lib -L/home/cygwin/cygwin-1.3.10/usr/lib/w32api -L/home/cygwin/cygwin-1.3.10/usr/bin ./.libs/libguile.a /home/fred/cvs/guile/cygwin/libltdl/.libs/libltdl.a
guile.o: In function `main':
    /home/fred/cvs/guile/cygwin/libguile/../../guile-core-1.6/libguile/guile.c:90: undefined reference to `lt_preloaded_symbols'

but the static version cross builds fine.  Of course, I'm enquiring at
Cygwin and will continue to look into this.

Please let me know what needs to be done to get this into CVS.

Greetings,
Jan.
