Hi, I was trying to build the C application swish-e on the Sourceforge Sun Ultra60 - Debian 3.0.
Swish-e allocates memory from a memory pool. The application byte-aligns the allocated pointers based on the sizeof(void *). (Actually the original programmer used sizeof(long) ). So on 4 byte machines you would get pointers that end in 0, 4, 8, and C hex. On DEC alpha sizeof(void *) == 8 so the pointers low byte is 0 and 8. Now the problem is that on sparc64 sizeof(void *) == 4 but we need to align our pointers on 8-byte boundaries otherwise we get SIGBUS errors. So, can anyone suggest a way in C to test for this? Something like #if defined(__sparc64__) # define PointerAlign 8 #else # define PointerAlign sizeof( void * ) #endif My C skills are not great, and I know much less about porting. So it would be great to find a reasonably potable way to set the align size -- any suggestions are more than welcome. Thanks. -- Bill Moseley mailto:[EMAIL PROTECTED]
