Re: [aseek-users] SUN

[Kir Kolyshkin]

The problem is aspseek is using highly-packed structures here and there, and get the bytes from those structures ("structures" here means not C struct, but some in-memory region, for example in ULONG (4 bytes) we can have weight as a first byte, and some other variable in the next 3 bytes). So ASPseek using type conversion here and where, sometimes leading to unaligned access.

To get the full picture, look into changes I have made in 'aspseek_solaris' CVS branch. For example:

cvs -z9 diff -u -r v_1_2_9 -r aspseek_solaris > sol.diff

(I have forked aspseek_solaris off 1.2.9pre, not 1.2.9, therefore some changes in diff you will get are irrelevant).

Hello, all,

Did somebody managed to compile and use ASPseek on a SUN server with

Solaris

9?

As I have already mentioned before, ASPseek do not work on hardware that doesn't support unaligned memory access. SUN servers are among them. So,
compiling ASPseek successfully do not yet means it will work.

To check your system, compile and run a simple program:

#include <stdio.h>
int main(void)
{
int i = 1234;
char * cp = (char *)&i;
char j = *(cp + 1);
printf("%d\n", j);
}

On my box, result is 4. It can be different on arch that has a different byte order, but if you will receive "Bus error" or something like that,
that means ASPseek will not work on your arch.

I have managed to almost fix it (in a separate CVS branch named aspseek_solaris), but the work is not finished. To finish it, I need some expressed interest from somebody who wants to run ASPseek on Solaris.
