Can't #include <stdlib.h> on Solaris

I'm working on Solaris x86 and have installed gcc4 using the OpenCSW packages. A simple test program below will not compile:

#include <stdio.h>
#include <stdlib.h>

main()
{
   printf("Hello, world\n");
}

It builds and runs fine if I don't have the stdlib.h include. When stdlib.h is in I get the following errors:

开发者_StackOverflowbash-3.00$ g++ -I/opt/csw/include test.cpp
In file included from /opt/csw/gcc4/lib/gcc/i386-pc-solaris2.8/4.3.3/include-    fixed/stdlib.h:27,
                 from test.cpp:2:
/usr/include/iso/stdlib_iso.h:107: error: expected initializer before '__NORETURN'
/usr/include/iso/stdlib_iso.h:124: error: expected initializer before '__NORETURN'
/usr/include/iso/stdlib_iso.h:132: error: multiple parameters named '_RESTRICT_KYWD'

I think this might be some sort of conflict between OpenCSW and the default libraries, but I'm not sure how to fix it. Can anybody help?

Just remove -I/opt/csw/include from your command line.

Try running one of the fixheaders or fixincludes commands that should be part of your gcc installation. There is likely a mismatch between the gcc package which is built for Solaris 8 according to its name and the Solaris release you are running, presumably Solaris 10 or newer.

Can't reproduce on Solaris 10 x86, neither with nor without -I:

-bash-3.00$ /opt/csw/gcc4/bin/g++ test.cpp
-bash-3.00$ /opt/csw/gcc4/bin/g++ -v
