I wanna install Xen-4.2-unstable on CentOS 5.5 x86-64, but it need yajl-devel package, which CentOS 5.5 doesn''t support. So I decide to install it from source code. But when I "make tools", it also tells me ./chk build Xen CHECK-BUILD Wed Dec 14 00:52:18 CST 2011 Checking check_crypto_lib: OK Checking check_curl: unused, OK Checking check_libaio_devel: OK Checking check_libaio_lib: OK Checking check_openssl_devel: OK Checking check_python: OK Checking check_python_devel: OK Checking check_uuid_devel: OK Checking check_x11_devel: OK Checking check_xgettext: OK Checking check_xml2: unused, OK Checking check_yajl_devel: *** check_yajl_devel FAILED: can''t find libyajl.so Checking check_yajl_lib: *** check_yajl_lib FAILED: can''t find libyajl.so.1 version 1 I copied libyajl.so* files to /usr/lib/ and /usr/lib64/ and /usr/local/lib/ and /usr/local/lib64. But the messages are the same. How can I install yajl-devel on CentOS 5.5.

That got me the first time I built 4.2-unstable Mike _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Should I be using CONFIG_PREEMPT for Linux 3.2 kernel?
I just ran across an old article about this and noticed that my servers aren''t running with these two options set to y: CONFIG_PREEMPT CONFIG_PREEMPT_BKL Should they be? Thanks. Mike
