vmtools安装后不能实现开发主机和Linux虚拟机之间的文件夹共享的问题解决

以前用ubuntu12.04一直没有问题。最近心血来潮将版本更新到最新后发现共享文件夹不能用了。所以就重新安装vmtools。但是在编译vmhgfs时报错。错误如下：

In file included from ./arch/x86/include/asm/percpu.h:44:0,
                 from ./arch/x86/include/asm/preempt.h:5,
                 from include/linux/preempt.h:18,
                 from include/linux/spinlock.h:50,
                 from include/linux/mmzone.h:7,
                 from include/linux/gfp.h:5,
                 from include/linux/mm.h:9,
                 from include/linux/pagemap.h:7,
                 from /tmp/modconfig-p8BmWh/vmhgfs-only/inode.c:29:
/tmp/modconfig-p8BmWh/vmhgfs-only/inode.c: In function ‘HgfsPermission’:
include/linux/kernel.h:834:27: error: ‘struct dentry’ has no member named ‘d_alias’
  const typeof( ((type *)0)->member ) *__mptr = (ptr);                            ^
include/linux/list.h:687:40: note: in expansion of macro ‘container_of’
 #define hlist_entry(ptr, type, member) container_of(ptr,type,member)
                                        ^
include/linux/list.h:698:15: note: in expansion of macro ‘hlist_entry’
     ____ptr ? hlist_entry(____ptr, type, member) : NULL; 

根据打印信息可以知道是HgfsPermission函数中struct dentry没有成员d_alias。这就奇怪了。上网查了下原因居然是vmware的vmhgfs模块在unbutu最新发行版下存在bug。在安装是需要打补丁或者手动修改一下就可以。下面说明手动修改怎么改。

1.进到vm tools中源码所在的位置

cd vmware-tools-distrib/lib/modules/source

2.解压vmhgfs.tar

sudo tar xf vmhgfs.tar

3.修改文件inode.c

　　先查看内核的版本。我这里是3.16.0

uname  -a
Linux ubuntu 3.16.0-38-generic #52-Ubuntu SMP Thu May 7 10:51:21 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

　　修改vmhggs.tar解压后的文件inode.c.进入vmhgfs-only文件夹中。用vim或者gedit修改

第1925行

#if LINUX_VERSION_CODE < KERNEL_VERSION(3, 16, 0)
                           d_alias) {
#else
                           d_u.d_alias) {
#endif

第1983行

#if LINUX_VERSION_CODE < KERNEL_VERSION(3, 16, 0)
         struct dentry *dentry = list_entry(pos, struct dentry, d_alias);
#else
         struct dentry *dentry = list_entry(pos, struct dentry, d_u.d_alias);
#endif

3.文件修改完后备份原来的vmhgfs.tar

mv vmhgfs.tar vmhgfs.tar.orig

4.重新打包，用修改后的源码生成新的vmhgfs.tar

tar cf vmhgfs.tar vmhgfs-only

5.按照先前的步骤重新安装即可。
