stdio.h not found on Solaris 11

Hi friends,
I hope u r doing well. I have just installed Solaris 11, and it seems that solaris 11 doesn't come with all the packages, one has to do everything manually. I download gcc from sunfreeware.com and installed it. After setting up the path variable, I tried to compile the hello world program in c, and here I face this error.

 
 
gcc Hello.c -o Hello
Hello.c:1:20: stdio.h: No such file or directory

I searched for stdio.h by

find / -name stdio.h -print

and found stdio.h under /usr/include/ast/stdio.h

But when I opended this file, it reads as

vi /usr/include/ast/stdio.h

I have no idea what to do. Could you please help me set up gcc on Solaris 11??

Thanks in advance!

Last time I checked, sunfreeware had no gcc package suitable for Solaris 11. I would suggest to remove the gcc package you installed from there and use the Solaris 11 packaging command instead:

 $ sudo pkg install gcc-3

This will install gcc and all required dependencies automatically.

Looks like an incomplete install of Solaris 11. What exactly was installed?

It's not uncommon for stdio.h to just include a different file on its own. gentoo for instance does a bit of magic with paths to have slightly different include files for different architectures(so that some constants change appropriately). What's weird is that your compiler couldn't find it...

/usr/lib/stdio.h is not part of some default Solaris installations.
It can be installed with this command:

# pkg install system/header
