============ building CROSS
You can always build one yourself. Download the CDK source, and do the
following:
$ mkdir /cygwin-b20
$ cd /cygwin-b20
$ tar zxvf /tmp/dev-src.tar.gz
$ cd src
$ mkdir CROSS
$ cd CROSS
$ ../configure --prefix=/usr/local/cygb20 --target=i386-cygwin32 -v
$ make > make.log 2>&1
[ check for errors . If OK ]
$ make install > install.log 2>&1
After you're done, add it to path (if you're using a bourne-shell
compatible, otherwise use csh syntax).
$ export PATH=$PATH:/usr/local/cygb20/bin
$ i386-cygwin32-gcc -v
[ should report egcs-1.1 etc ]
All the binaries for i386-cygwin32 target are prefixed with i386-cygwin32-
prefix.
============ building NATIVE tools using CROSS tools just built.
Now if you want to build native tools on eg., a i686-pc-linux-gnu box with
the same pathnames that wCygnus uses:
$ cd /cygwin-b20/src
$ mkdir NATIVE
$ cd NATIVE
$ ../configure --prefix=/Cygnus/cygwin-b20 \
--exec-prefix=/Cygnus/cygwin-b20/H-i586-cygwin32 \
--target=i386-cygwin32 --host=i386-cygwin32 \
--build=i686-pc-linux-gnu -v
$ make > make.log 2>&1
[ check for errors . If OK ]
Now of course, you want to install it to a *DIFFERENT* location than
/Cygnus/cygwin-b20 on your Unix host before creating an archive to
copy to a Cygwin box. Let's say you first install it to /tmp/cygwin.
$ make prefix=/tmp/cygwin exec_prefix=/tmp/cygwin/H-i586-cygwin32 \
install > install.log 2>&1
$ cd /tmp/cygwin
$ tar zcvf /tmp/dev-cygwin-b20.tar.gz .
Copy /tmp/dev-cygwin-b20.tar.gz to your Cygwin box and unpack:
[win32]$ cd /Cygnus/cygwin-b20
[win32]$ tar zxvf /tmp/dev-cygwin-b20.tar.gz
