2096.0. "cc does not allow #pragma pack to be used in a non-global scope?" by TUXEDO::LU () Tue Feb 18 1997 14:58

I am using DEC C (Digital Unix Compiler Driver 3.11) on OSF1 V3.2 62 alpha.

1 foo()
2 {
3 #pragma pack(4)
4    struct my_struct {
5	char a;
6	...
7    };
    ...
}

When compile the above code using cc, the following errors occur.

/usr/lib/cmplrs/cc/cfe: Error : ..., line 3: Syntax Error
 __pragma(4, 4);
 ^

/usr/lib/cmplrs/cc/cfe: Error: ..., line 4: Syntax Error
   struct my_struct {
___^

Interesting enough, cxx has no problems with the same code.

Any insight will be appreciated.

	You're using the old ucode C compiler (acc). To use DEC C on DIGITAL UNIX V3.2 you need to use the -migrate option. -dave-
2096.2	Try cc -migrate	DECCXL::WIBECAN	That's the way it is, in Engineering!	`Tue Feb 18 1997 15:37`	7
	Under Unix V3.2, are you using cc -migrate? Without the -migrate switch, you would be using the older acc compiler, rather than DEC C. A test on a handy V3.2 system confirms that the error appears under acc and disappears with cc -migrate. Brian
