To Linux fans,

When I compliled my code, the line, listed below, in the header file types.h has an compilation error. If you know what causes the error, please help.

Thanks in advance.

Link to the header file types.h
http://tomoyo.sourceforge.jp/cgi-bin.../linux/types.h

The line of code that has error:
typedef __u32 __bitwise __be32;

Error Message:
Multiple markers at this line
- error (dcc:1082): illegal storage class
- error (dcc:1633): parse error near '__le32'
- error (dcc:1117): identifier __u32 not an
argument

Question1: What does the keyword "__bitwise" mean?

Question2: Where is __u32 defined?

Question3: How can I covert this code to WindRiver VxWork Kernel code?

The __bitwise typedef is a compilation attribute that is not used by gcc. Its purpose was to prevent issues with bit order, by preventing conversions between types with different endian types. You can leave it as defined in types.h, it will not affect your code.

The fixed width words such as __u32 are defined in asm/types.h (which includes for example asm-generic/int-l64.h). You may need to define these for your particular CPU.

The WindRiver code will already have its own type definitions, which would be preferable to the Linux ones if you are running or porting to a WindRiver system.
