Gentle People?

I am currently running gcc 3.1 on both my Ultra 5
Solaris 8 Sparc machine and on Solaris 8 Intel machine.
The C source code that compiles and executes perfectly on
the Ultra 5 will not compile on the Intel machine!

The compilation errors, shown below, seem to relate to
syntax errors, and not simply missing files. Remember this
same code compiles perfectly on the Sparc machine. There is no
inline assembly language or obvious machine dependent code
involved.

Why would there be such a difference in the between gcc on
Sparc versus Intel?

Someone mentioned that the header files are different:
I wonder why? I would of thought at that level of abstraction
they would be identical.


Thanks for the help.

Have you tried a more recent gcc or Sun Studio? The code you posted
looks clean, assuming UF_SIZE is defined and you include the header for
exec_struct_sun.

Otherwise, check to see if there are any incorrect conditional
compilation macros that exclude exec_struct_sun. Sometimes developers
wrongly assume Solaris==Sparc in conditional includes.

Wow, that's old stuff.

It's hard to tell. There shouldn't be. A good place to start would
be examining the output of 'gcc -E' -- find out what the preprocessor
is actually doing with this code. There is likely some difference
between the two machines beyond the parts you've mentioned.

Not exaclty the same, but,

a loong while ago I had same problems, using same gcc version on a
Solaris 8 (sparc) and a Linux RH 8 ( I know, as I said)
The sintax differences were all missing new line between declarations,
If I remmebrer correctly.

I eneded p writing under Linux and recompiling unde Solaris where it
didn't make a diffference.
