The root auto configure script in 2.0b1 is broken. It assumes the packages use version current, where as they are called v2_b1. This means it cannot find them down in the tree. Also, host has been renamed tools/src and the approrpriate changes have not been made in the auto configure script. This makes a workaround for the missing synth auxilary code more difficult
The target side configury should be able to accommodate non-'current' package versions. It looks like this should be trivial by using a wildcard instead of 'current' when assigning FOUND_CONFIGURES in the configure script. Similarly, SUBDIRS="tools/src" rather than SUBDIRS="host" should work. To avoid the need for release engineering tweaks, I suggest that the top level configure looks for both "host" and "tools/src". There's an underlying problem with the use of a relative path to reference files in the acsupport directory from the host-side configure script. This causes problems when renaming "host" -> "tools/src" for releases. For eCos 2.0b1 I simply duplicated the acsupport directory and contents to work around this. In the long term, it would be good to move "host" -> "tools/src" in the CVS repository itself.
