Hi Clemens, I recently successfully built the whole OpenJDK using gcc 3.3.3 on Suse Enterprise Linux 9.3 (see http://weblogs.java.net/blog/simonis/archive/2008/01/hotspot_develop.html#Build). I had no linking problems. Currently I'm building HotSpot only on OpenSuse 10.0 with gcc 4.0.2.
I think with every gcc newer than 3.2.2 (which is the recommanded GCC version if you follow the Readme: http://hg.openjdk.java.net/jdk7/jdk7/raw-file/tip/README-builds.html#gcc) youll have to disable the treatment of warnings as errors (see my blog entry mentioned above). Regarding your linking problem: is this perhaps the 'cannot restore segment prot after reloc' problem (BugID 6538311: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6538311). This is caused by SELinux - there's a workaround in the bug description.
