[omniORB] static library

Hello,
I've built an application using omniORB and while I'm generating dynamic ELF
everything is working fine.
The problem is when I generate a static binary for i386 cpu : there is a
SIGSEGV in function ORB_init.

here is the output from valgrind :

Does anybody know something about that?

there is a SIGSEGV in function ORB_init.

[snip]

Please post the piece of code where you call ORB_init(), so that it can
be seen what arguments you are passing.

Here is the call of oORB_init. arguments are :

std::string m_corbaVersion = "omniORB4";
argc = 14;
argv[0] = "-ORBscanGranularity";
argv[1] = "1";
argv[2] = "-ORBendPoint";
argv[3] = "giop:tcp:10.10.10.123:10002";
argv[4] = "-ORBclientCallTimeOutPeriod";
argv[5] = "15000";
argv[6] = "-ORBserverCallTimeOutPeriod";
argv[7] = "15000";
argv[8] = "-ORBtraceLevel";
argv[9] = "40";
argv[10] = "-ORBoutConScanPeriod";
argv[11] = "0";
argv[12] = "-ORBinConScanPeriod";
argv[13] = "0";

CORBA::ORB_init( argc, argv, m_corbaVersion.c_str() );

thanks again

Hi,

you better use the 4th parameter of ORB_init() to pass ORB options.

Anyway, argv[0] is reserved for the program name, so if you really want
to program it like that, you have argc=15 and have your args at
argv[1]..argv[14]. You should also append an extra zero argument at
argv[argc].

Thank you for your answer.
I'll try to modify this and I'll tell you the result.
But Is there any reason for my application working fine when compiling as
dynamic ELF and not working when compiling as static ?

The problem is when I generate a static binary for i386 cpu : there is a
SIGSEGV in function ORB_init.

The problem is probably that the linker has removed some things that
have static initialisers. It thinks they are not used, when actually
they are. The strange thing is that there is already code that tries to
force linkage of the necessary things.

Try editing include/omniORB4/CORBA_sysdep.h to define
OMNI_NEED_STATIC_FUNC_TO_FORCE_LINK for your platform.

Cheers,

Duncan.
