"Multiple declaration for mbstate_t"

hi all,

I compiled a simple Cpp program on solaris. It was giving this error

Code:

"/usr/include/iso/wchar_iso.h", line 100: Error: Multiple declaration for mbstate_t.
"/opt/SUNWspro/SC5.0/include/CC/./iosfwd", line 51: Error: The name mbstate_t is ambiguous, std::mbstate_t and std::mbstate_t.
"/opt/SUNWspro/SC5.0/include/CC/./iosfwd", line 78: Error: The name mbstate_t is ambiguous, std::mbstate_t and std::mbstate_t.
"/opt/SUNWspro/SC5.0/include/CC/rw/iotraits", line 56: Error: The name mbstate_t is ambiguous, std::mbstate_t and std::mbstate_t.

By default it is taking the /usr/include/iso/wchar_iso.h for compiling. How can i override/remove default include path for compiling a program with CC.

Regards,
Murugesan

From the error message(s), I'm assuming that Workshop C++ compiler 5.0 is being used to compile the C++ program.

On Solaris 8 and prior versions, the patch 107311-10 or later must be installed, to compile the test case successfully.

Do the following:

1) Check for the patch:
showrev -p | grep 107311

2) Download and install, latest version of 107311 from sunsolve.sun.com.

hi technopark02,

I found the work around.
CC -library=iostream a.C
gave me the solution

man CC
iostream
Use libiostream, the classic
iostreams library. (If using this value,
do not use Cstd)

anyhow thanks for the other soln.
