fedora12 eclipse 不能正常启动

解决方法：禁用selinux

Shell代码
sudo gedit /etc/sysconfig/selinux

修改SELINUX=enforcing 为 SELINUX=disabled

重启reboot，能启动了，我测试过。
或者根据selinux的提示
Fix Command:

chcon -t execmem_exec_t '/home/hadoop/eclipse/eclipse'
即可以解决问题


Summary:

SELinux is preventing /home/hadoop/eclipse/eclipse from making the program stack
executable.

Detailed Description:

The eclipse application attempted to make its stack executable. This is a
potential security problem. This should never ever be necessary. Stack memory is
not executable on most OSes these days and this will not change. Executable
stack memory is one of the biggest security problems. An execstack error might
in fact be most likely raised by malicious code. Applications are sometimes
coded incorrectly and request this permission. The SELinux Memory Protection
Tests (http://people.redhat.com/drepper/selinux-mem.html) web page explains how
to remove this requirement. If eclipse does not work and you need it to work,
you can configure SELinux temporarily to allow this access until the application
is fixed. Please file a bug report.

Allowing Access:

Sometimes a library is accidentally marked with the execstack flag, if you find
a library with this flag you can clear it with the execstack -c LIBRARY_PATH.
Then retry your application. If the app continues to not work, you can turn the
flag back on with execstack -s LIBRARY_PATH. Otherwise, if you trust eclipse to
run correctly, you can change the context of the executable to execmem_exec_t.
"chcon -t execmem_exec_t '/home/hadoop/eclipse/eclipse'" You must also change
the default file context files on the system in order to preserve them even on a
full relabel. "semanage fcontext -a -t execmem_exec_t
'/home/hadoop/eclipse/eclipse'"

Fix Command:

chcon -t execmem_exec_t '/home/hadoop/eclipse/eclipse'
