Get "Pointers are not assignment-compatible" when compiling server skeleton generated by rpcgen

[Kwang Tan]

Hi there, I'm compiling with warning error for the server skeleton generated by 'rpcgen'.

Here's my "log":
=================================
$ ll
-rw-r--r-- 1 kwang users 210 Jan 19 18:31 rpc.x

$ cat rpc.x
const MAXNAMELEN = 2048;
typedef string x_string;

program X_RPC_FUNCTION_NUMBER
{ version X_RPC_FUNCTION_VERSION
{ x_string X_TEST(string) = 1;
} = 1;
} = 0x20000001;

$ rpcgen rpc.x

=================================

There are unsatisfied symbols which I've taken out for this thread. My concern and surprise is 'rpc_svc.c' is generated by 'rpcgen' but shows "warning 604" error when being compiled by 'cc'. Is there something wrong in 'rpc.x' (RPC Protocol Specification File) which thus results in this error?

Attached 'rpc_svc.c' is for reference. Thanks.

One more piece of information: All these take place on 64bit HP-UX operating system.

Hello,

Which version of "cc" compiler you are using ? #>what `which cc`

Hi Arun,

are related with compiler compatible warnings. Which will not effect the binary.

/usr/ccs/bin/ld: Unsatisfied symbols:
... ... is going to be the problem. You have link the needed libraries when compilation phase. Export with -L option or directly link that library.

May be some library has to be linked during run time with SHLIB_PATH or LD_LIBRARY_PATH

Hello,

What are the Unsatisfied symbols you got? You can trun off warning while compiling rpc_svc.c by -w

Hi Muthu and Arun

Here is the output:

=================================

But I am much concerned about the warning error "warning 604: Pointers are not assignment-compatible" than about the unsatisfied symbols this time. From your experience, does it mean we can ignore the warning error?
