CentOS7安装VMwareTools过程中报错导致hgfs下没有出现共享文件

在VM上安装了CentOS虚拟机,想使用共享文件夹,安装VMwareTools,hgfs下找不到响应的目录,但是使用vmware-hgfsclient命令 却能看到我设置的共享目录.

仔细再进行了一遍检查,发现在安装VMwareTools时编译报错.

报错如下

通过查看后发现因为centos 7的Linux内核用的3.10版本,在函数 wait_on_bit_io()中有三个参数,而vmtool的代码在内核3.19后才用3个参数的wait_on_bit_io()函数,代码如下

1639 #if LINUX_VERSION_CODE >= KERNEL_VERSION(3, 19, 0)
1640    return wait_on_bit_io(&req->wb_flags,
1641                          PG_BUSY,
1642                          TASK_UNINTERRUPTIBLE);
1643 #elif LINUX_VERSION_CODE >= KERNEL_VERSION(2, 6, 13)
1644    return wait_on_bit(&req->wb_flags,
1645                       PG_BUSY,
1646 #if LINUX_VERSION_CODE < KERNEL_VERSION(3, 17, 0)
1647                       HgfsWbRequestWaitUninterruptible,
1648 #endif
1649                       TASK_UNINTERRUPTIBLE);
1650 #else

个人推测,在其他linux版本中可能也会出现类是的问题,只要看看报错源码,如果是由于#if LINUX_VERSION_CODE < KERNEL_VERSION(3, 17, 0),这种判断造成的报错,只要把宏改成当前的版本号,一般都能解决问题.

vmware-tools-distrib/lib/modules/source的目录下有不少tar文件,我是根据报错的提示

“/tmp/modconfig-71euqe/vmhgfs-only/page.c:1649:23: error: too many arguments to function ‘wait_on_bit’” 一个个去解压了找的

解压指令

tar xf vmhgfs.tar

修改目录下的page文件的1639行

1639 #if LINUX_VERSION_CODE >= KERNEL_VERSION(3, 19, 0)

改为如下↓

1639 #if LINUX_VERSION_CODE >= KERNEL_VERSION(3, 10, 0)

解压后修改完成打包指令

tar cf vmhgfs.tar vmhgfs-only

然后执行vmware-install.pl 问题解决
