Hello,
      When I run the program in the demo/fipa_test directory, it had some problems.The error messages are as follows:


      MobileC > ERROR: cannot find file 'fipa_acl.h'

ERROR: cannot execute command 'agentchscriptW95uyQ'

In the .xml files  of this directory, they  include  sentences  "#pragma package "/usr/local/ch/package/mobilec" ",
but I can't find mobilec in package directory.

---------------------------------------------------------------------------------------------

The second problem is that when I run a simple socket program(which can run correctly itself in a .c file) by using a mobile agent(in a  .xml file) ,and then  errors occured as follows:

MobileC > ERROR: argument 1 of the function is undefined or not a valid expression
ERROR: number of argument is 0, need 2 arguments
ERROR: syntax error before or at line 6 in file /usr/local/ch/toolkit/embedch/lib/libopt/inet_pton.chf

  BUG:     fptr = dlsym(_ChArpaInet_handle<== ???
ERROR: cannot execute command 'agentchscriptH06The'

I am not familiar about both Mobile-C and Ch ,so it is really difficult for me to sovle these problems in a short time. I have read the user_guide many times, but I cannot find the anwsers.If there any other documents with which I can help myself? Thank you .
