[omniORB] Issue transfering double over the network on x86_64/arvm8

[Benjamin Bertrand]

Hi,

I have been cross-compiling omniorb for Apple M1 and we haven't seen that issue.
When cross-compiling I had to use "--disable-longdouble" option, otherwise I get a compilation error:

In file included from ../../../../../include/omniORB4/CORBA.h:122:
../omniORB4/corbaidl_defs.hh:2076:66: error: no member named 'LongDouble' in namespace 'CORBA'
class LongDoubleSeq : public _CORBA_Unbounded_Sequence< ::CORBA::LongDouble >  {
                                                        ~~~~~~~~~^
../omniORB4/corbaidl_defs.hh:2085:71: error: no type named 'LongDouble' in namespace 'CORBA'; did you mean 'LongDoubleSeq'?
  inline LongDoubleSeq(_CORBA_ULong _max, _CORBA_ULong _len, ::CORBA::LongDouble* _val, _CORBA_Boolean _rel=0)
                                                             ~~~~~~~~~^~~~~~~~~~
                                                                      LongDoubleSeq

Could that explain that we haven't seen this issue?
Is that the correct thing to do?

Thanks

Benjamin

No, that is not sufficient. There is code that is compiled into the
omniORB libraries that depends on that definition too. The only way for
a complete fix is with recompiled libraries as well as recompiling the
application code.
