Hi, I got the following error when use rtiddsgen to generate types files.
ERROR com.rti.ndds.nddsgen.antlr.auto.IdlParser tpc_alarm.idl line 11:0 no viable alternative at input '# 11 "tpc_alarm.idl" 3\n' in member declaration
ERROR com.rti.ndds.nddsgen.Main Fail: java.lang.Exception: The file couldn't be parsed and the rawTree wasn't generated
INFO com.rti.ndds.nddsgen.Main Done (failures)
The idl files are listed:
// tpc_common.idl
#ifndef __TPC_COMMON_IDL__
#define __TPC_COMMON_IDL__
#define TPC_NAME_LEN 16
struct TPC_Common {
char name[TPC_NAME_LEN];
unsigned long long loopCounter;
unsigned long long timeStamp;
};
#endif
// tpc_alarm.idl
#ifndef __TPC_ALARM_IDL__
#define __TPC_ALARM_IDL__
#include "tpc_common.idl"
struct TPC_AlarmPlayerCmd {
TPC_Common common;
boolean on;
char alerter[TPC_NAME_LEN];
unsigned long long id;
};
#endif
Build command: rtiddsgen -replace -language C++ -d . tpc_alarm.idl
RTI context DDS: 6.1.1
OS: Ubuntu 20.04
GCC version: gcc version 9.4.0 (Ubuntu 9.4.0-1ubuntu1~20.04.1)
From the post, I learned this error is caused by GCC-11, however, the gcc version that I used is 9.4.0.
And I also installed gcc version 7.5.0 (Ubuntu 7.5.0-6ubuntu2) and gcc version 8.4.0 (Ubuntu 8.4.0-3ubuntu2), and builded with the following commands, and got the same error!
rtiddsgen -ppPath /usr/bin/cpp-7 -replace -language C++ -d . tpc_alarm.idl
rtiddsgen -ppPath /usr/bin/cpp-8 -replace -language C++ -d . tpc_alarm.idl
However, rtiddsgen works fine with gcc version 8.3.0 (Debian 8.3.0-6) on Debian buster!
So, how can I solve the problem?
from the help for rtiddgen:
-ppPath <path to the preprocessor>: Preprocessor path
The default value is "cpp" for non-Windows architectures and
"cl.exe" for Windows architectures.
If you use -ppPath to provide the full path and filename for
"cl.exe" or the cpp preprocessor, you must also use -ppOption (described below)
to set the following preprocessor options:
If you use a non-default path for "cl.exe", you also need to set:
-ppOption /nologo -ppOption /C -ppOption /E -ppOption /X
If you use a non-default path for cpp, you also need to set:
-ppOption -C
-ppOption <option>: Preprocessor option
try adding "-ppOption -C" to the command arguments when you are using "-ppPath".
I tried the following commands and got the same error.
rtiddsgen -ppPath /usr/bin/cpp-7 -ppOption "-C" -replace -language C++11 tpc_alarm.idl

Sorry, if that doesn't work, then your best path is to work with RTI's support group which you can contact through your RTI Account team or local RTI distributor.
After several tries, if env
CPLUS_INCLUDE_PATHincludes current path (such asCPLUS_INCLUDE_PATH=<some path>:) , it will cause the problem.Thanks for letting us know that you got it working.
