Cross development

See http://www.nslu2-linux.org/wiki/Optware/AddAPackageToOptware

In short, build openwrt-ixp4xx release first, then

 svn co http://svn.nslu2-linux.org/svnroot/optware/trunk optware
 cd optware
 make openwrt-ixp4xx-target
 cd openwrt-ixp4xx
 make directories ipkg-utils
 make <foo>-ipk
 make <bar>-dirclean <bar>-check

Native development

1) setup optware ipkg on openwrt-ixp4xx following http://www.nslu2-linux.org/wiki/OpenWrt/HomePage

2)

 /opt/bin/ipkg update

3)

 /opt/bin/ipkg install optware-devel

4) [optional, but recommended] login as non-root user

5) (you can use any directory, change the following accordingly)

 cd $HOME
 svn co http://svn.nslu2-linux.org/svnroot/optware/trunk optware

6)

 cd $HOME/optware; make openwrt-ixp4xx-target

7)

 cd $HOME/optware/openwrt-ixp4xx
 make directories ipkg-utils

8)

 make hello-dirclean hello-check

replace hello with other package you want to build.

Please note that most optware packages are cross built. We tried to accommodate both native build and cross build, but there can be some packages that are only buildable in cross compilation environment. Native build is significantly slower than cross build. It's possible to speed up C/C++ packages with distcc.
