The GCC version is 4.1.2 20070925 (Red Hat 4.1.2-27). BTW, for long-term plan, I will post a package to Linux and its patch is only for 2.6.14. for testing, simulation and verification, In short term, I think the UML should be workable in the Linux version after 2.6.9 and I cannot find any failure casein the google search for UML building. Do I lost something?
