RPCGEN problems

Hi.


I would like to use RPCGEN to create the .h and .c files for my demo XDR
serialization / deserialization program.


My 'test.x' file contains:
----
const MAXNAMELEN = 64;
struct bla_s
{
    string str<MAXNAMELEN>;
    double r;
    int i;
};
----


Whenever I ran 'RPCGEN FROMFILE('/test.x')', I get the following error:
----
CPD0018:  String ').        ' contains a character that is not valid.
CPF0001:  Error found on *N command.
CPFA0A9:  Object not found.  Object is
/QSYS.LIB/QTEMP.LIB/QRPCSRC0.FILE/test0.MBR.
CPC7301:  File QACZEXPAND created in library QTEMP.
CPF4102:  File QRPCSRC0 in library QTEMP with member TEST0 not found.
CZS0611:  File QRPCSRC0 with member TEST0 could not be opened or member
TEST0 could not be found in file QRPCSRC0.
CPFB413:  Failure in processing the
/QSYS.LIB/QTEMP.LIB/QACZEXPAND.FILE/test0.MBR file.
CPC2191:  Object QACZEXPAND in QTEMP type *FILE deleted.
CPFB416:  CVTRPCSRC or RPCGEN command failed.
----


I'm a little bit confused as I get the SAME error even if I run RPCGEN
over an empty file. If RPCGEN is ran over an nonexisting file, the error
message is different.


Do anyone have a hint or maybe even better an working example?


Best regards,
