I tried compiling my program to ubuntu using gcc and i got no errors, how ever when i compile it to opensuse 10.3 I get these error:

Looks like either you're compiling a module as if it were a program or vice-versa.

exactly, i'm compiling a program sir. do you have any idea what seems to be the problem?

Do you include both <sys/types.h> and <linux/types.h> in the file that has the error? Please list the includes for the file that has the error, and also the includes for those files included (if they are your files, too.)

I did'nt include both <sys/types.h> and <linux/types.h>. I am using sys/statvfs but I am also using something from <include/linux/> which is cdrom.h. could this be a problem?

This is really weird because i can compile in Ubuntu but I can't compile in opensuse. What is the difference between these distribution? I can't really understand the conflict made.

What in <linux/cdrom.h> do you need that you can't get somewhere else?

The top of /usr/linux/cdrom.h on my (Mandriva) system has this: So apparently the author wants you to delete the #include lines for sys/types.h and sys/statvfs.h.

If that leaves some things undefined or undeclared, maybe you could break your file into two files and only include cdrom.h in one of them.

You need to make sure that anything that uses one version of a typedef isn't used by something that uses another. In other words, you should probably isolate the use of <linux/cdrom.h> to a single source file and give it an interface .h (if it even needs one) that doesn't use any of those typedefs to avoid malformed binary code. You'll have major problems if one source thinks a type is a different size or sign than another source does, which can easily happen with typedefs that differ source-to-source.
