2.4.4 Building SDCC using Cygwin and Mingw32</A>
</H2>

<P>
For building and installing a Cygwin executable follow the instructions
for Linux.
<BR>
<BR>
On Cygwin a ''native'' Win32-binary can be built, which will
not need the Cygwin-DLL. For the necessary 'configure' options see
section 'configure options' or the script 'sdcc/support/scripts/sdcc_cygwin_mingw32'.
<BR>
<BR>
In order to install Cygwin on Windows download setup.exe from www.cygwin.com
<TT><A NAME="tex2html6"
  HREF="http://www.cygwin.com/">http://www.cygwin.com/</A></TT>. Run it, set the ''default text file
type'' to ''unix'' and download/install at least the following
packages. Some packages are selected by default, others will be automatically
selected because of dependencies with the manually selected packages.
Never deselect these packages!

<UL>
<LI>flex
</LI>
<LI>bison
</LI>
<LI>gcc ; version 3.x is fine, no need to use the old 2.9x
</LI>
<LI>binutils ; selected with gcc
</LI>
<LI>make
</LI>
<LI>rxvt ; a nice console, which makes life much easier under windoze
(see below)
</LI>
<LI>man ; not really needed for building SDCC, but you'll miss it sooner
or later
</LI>
<LI>less ; not really needed for building SDCC, but you'll miss it sooner
or later
</LI>
<LI>svn ; only if you use Subversion access
</LI>
</UL>
If you want to develop something you'll need:

<UL>
<LI>python ; for the regression tests
</LI>
<LI>gdb ; the gnu debugger, together with the nice GUI ''insight''
</LI>
<LI>openssh ; to access the CF or commit changes
</LI>
<LI>autoconf and autoconf-devel ; if you want to fight with 'configure',
don't use autoconf-stable!
</LI>
</UL>
rxvt is a nice console with history. Replace in your cygwin.bat the
line

<P>

<DL COMPACT>
<DT>
<DD>bash&nbsp;--login&nbsp;-i&nbsp;
</DD>
</DL>with (one line):

<P>

<DL COMPACT>
<DT>
<DD>rxvt&nbsp;-sl&nbsp;1000&nbsp;-fn&nbsp;Lucida&nbsp;Console-12&nbsp;-sr&nbsp;-cr&nbsp;red

<P>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;-bg&nbsp;black&nbsp;-fg&nbsp;white&nbsp;-geometry&nbsp;100x65&nbsp;-e&nbsp;bash&nbsp;--login
</DD>
</DL>Text selected with the mouse is automatically copied to the clipboard,
pasting works with shift-insert.
<BR>
<BR>
The other good tip is to make sure you have no //c/-style paths
anywhere, use /cygdrive/c/ instead. Using // invokes a network lookup
which is very slow. If you think ''cygdrive'' is too long, you can
change it with e.g.

<P>

<DL COMPACT>
<DT>
<DD>mount&nbsp;-s&nbsp;-u&nbsp;-c&nbsp;/mnt
</DD>
</DL>SDCC sources use the unix line ending LF. Life is much easier, if
you store the source tree on a drive which is mounted in binary mode.
And use an editor which can handle LF-only line endings. Make sure
not to commit files with windows line endings. The tabulator spacing<A NAME="514"></A>
used in the project is 8. Although a tabulator spacing of 8 is a sensible
choice for programmers (it's a power of 2 and allows to display 8/16
bit signed variables without loosing columns) the plan is to move
towards using only spaces in the source.
