Compiling Cygwin on Linux


Hi,

   I was wondering how one would compile cygwin-src on linux.
   I currently have a binutils and stage 1 gcc (a.la. "make all-gcc;
   make install-gcc") targeted for i686-pc-cygwin.
   I have tried the following
   ~/build_cygwin$ uname -a
   Linux gcc14 2.6.18-6-vserver-amd64 #1 SMP Sun Feb 10 17:55:04 UTC
   2008 x86_64 GNU/Linux
   ~/build_cygwin$ export CC=i686-pc-cygwin-gcc
   ~/build_cygwin$ ~/cygwin-1.5.25-11/configure
   --prefix=/home/rpeckhoff/boot_system/ --host=i686-pc-cygwin
   --build=x86_64-unknown-linux-gnu -v

   I get the following:
   loading cache ./config.cache
   checking host system type... i686-pc-cygwin
   checking target system type... i686-pc-cygwin
   checking build system type... x86_64-unknown-linux-gnu
   checking for a BSD compatible install... /usr/bin/install -c
   checking whether ln works... yes
   checking whether ln -s works... yes
   checking for i686-pc-cygwin-gnatbind... no
   checking for gnatbind... gnatbind
   checking whether compiler driver understands Ada... no
   checking how to compare bootstrapped objects... cmp
   --ignore-initial=16 $$f1 $$f2
   checking for correct version of gmp.h... no
   /home/rpeckhoff/boot_system/bin/../lib/gcc/i686-pc-cygwin/4.3.0/../../../../i686-pc-cygwin/bin/ld:
   crt0.o: No such file: No such file or directory
   collect2: ld returned 1 exit status
   *** The command 'i686-pc-cygwin-gcc -o conftest -g -O2   conftest.c'
   failed.
   *** You must set the environment variable CC to a working compiler.

   Does anyone know what the right configure flags for cygwin configure
   are? crt0.o is supposed to be compiled by cygwin. Thanks in advance.
