Hi,
I am working on HP UX 11.11 OS. Trying to build clamAV using gcc for 11.11 64 bit version.
I am getting above error. How to resolve that?

Hi,
found on the WEB:

2.
Could you try compiling the attachment, and running it, and noting the
output. Then do it again with each of the following compiler flags
added, one per re-compile:

-xmemalign=1s
-xmemalign=8i
-xmemalign=2i

Cheers,
-trog

int main(int argc, char **argv) {
#pragma pack(1)
struct { char c; long l; } s;
if (sizeof(s)==sizeof(s.c)+sizeof(s.l)) {
printf("ok\n");
} else {
printf("not ok\n");
}
}

Please let us know if either solves your problem !

Ambika,

ClamAV is included in the hpuxiexpress1 A.06.00-004 package (free download)

FWIW, if you want to pack a structure in gcc, you can use __attribute__((packed))

e.g.

typedef struct tagX
{
int A;
int B;
} __attribute__((packed)) X, *pX;
