[Libguestfs] guestfs_mount_local* api undefined symbols

Recently i deployed latest 1.17.40 on rhel6.1. When i ran a tiny program which was to test the function guestfs_mount_local() or those similar functions that mounts locally, Error prompted—undefined symbol guest_mount_local ! Why didn`t this undefined symbol error prompt when the program was first compiled,but occurred when it was run? Then i gave guestfish mount local a try in the shell, and found that ok.I thought it could not be something wrong with the installation.And then wierd happened—i ran the previous test program again,and it did mount the vm image on the host local directory! I doubted whether this was repeatable so i ran it again,and it failed with the same error “undefined symbol guestfs_mount_local”.
