Very glad to hear of the progress on this. In case it helps, I remembered something else over the weekend. When building the xenv tree, you're better off just typing make install from the outset. 'make all' will work in any given subtree, but each subtree depends on the installation of the previous subtree.
For example, this is probably why the use of 'ar' is failing. The missing directory actually does get created by the install step.
For the person who found the xenv configuration (linux host vs. linux-cross) confusing, here is the situation:
On RedHat 5.2, the compiler versions that shipped all worked correctly. The EROS build chain expects the ELF object file format, and it mostly works fine with binary files as normally generated for Linux.
Unfortunately, when 6.0 came along, RedHat moved to the egcs toolchain, which is badly broken. At that point, it became necessary to use a cross build even under linux. This was a mixed blessing. On a positive note, it means that everyone now uses the same toolchain, which eliminates one source of errors and allows for future cross-builds to other architectures. On the negative side, it means that everyone must now wrestle with the cross-build issues.
The upshot is that linux-cross is actually the right setting to use.
