I'm compiling c++ with extern "C" (without it doesn't work). I'm compiling exactly the same code that works on 64 bits. I'm only changing -m32 -march-i386 for compiler and -m32 for linker.
I noticed that the library appears on the list because I used LD_PRELOAD. But it still seem not to work, I guess because the code is not correct or something similar, because the speedhack works.
Yes, the 100% of programs (I've tested) are 64 bit working and 32 bit failing.
HELP is urgently required,
I run on SCO Unix 3 and this is the panic message that I get every time that I reboot 10U

Hi all,
I am trying to setup a program to use a device driver and am confusing buffer access between User and Kernel mode. I think all applications running in User space have to communicate with the device drivers using io control calls and then have some functions called back from the driver... (1 Reply)

I run my program which consists of one kernel module and one user mode process on a dual core server. The problem here is the kernel module consumes 100% of one core while the user mode process only consumes 10% of the other core, is there any solution that I can assign some computing... (1 Reply)

compat_30
COMPAT_30(8) BSD System Manager's Manual COMPAT_30(8)NAME
compat_30 -- setup procedure for backward compatibility on post-3.0 releases
SYNOPSIS
options COMPAT_30
DESCRIPTION
The compat_30 module allows NetBSD to run NetBSD 3.0 executables.
The support is present if the kernel was built with option COMPAT_30. It is not available as a loadable module.
Static executables typically need no additional setup. Dynamic binaries may require shared libraries whose major version number changed
since NetBSD 3.0, which are listed below. A shadow directory under /emul is not used; the libraries can be obtained from a NetBSD 3.0 dis-
tribution and installed in the original directories shown, as the major version number in the file name will prevent conflicts. If an
upgrade installation from NetBSD 3.0 has been done and these libraries are still present, nothing more need be done.

IMPLEMENTATION NOTES
COMPAT_30 enables the NetBSD 3.0 versions of the following system calls, whose syscall numbers and argument structures were changed after the
3.0 release to accommodate 64-bit filesystems: fhstat(2), fstat(2), getdents(2), lstat(2), stat(2).
The filehandle structure (formerly fhandle_t) was made opaque to userland and variable-sized. A fh_size argument was added to related
syscalls: fhstat(2), fhstatvfs(2), fhstatvfs1(2), fhopen(2), getfh(2). This changes the API and ABI of those syscalls, COMPAT_30 enables
binary compatibility with the old ABI. Source compatibility is not provided, as use of those syscalls is supposed to be rare.
The error code from the socket(2) syscall changed from EPROTONOSUPPORT to EAFNOSUPPORT in the case of an unsupported address family.
COMPAT_30 enables binary compatibility with the old ABI. Source compatiblility is not provided.
The struct ntptimeval used by ntp_gettime(2) changed with the implementation of timecounters.
SEE ALSO config(1), fhstat(2), fstat(2), getdents(2), lstat(2), stat(2), options(4)HISTORY
NetBSD offers back-compatibility options back to NetBSD 0.9, but the first to be documented with a manual page is compat_30.
BUGS
The compatible getdents(2) is unable to see directory entries beneath the top layer of a union, even though the real 3.0 getdents() did not
have that problem.
SECURITY CONSIDERATIONS
Programs with security impact that receive incorrect directory contents from getdents() may behave improperly, as when they are unable to
find, or find the wrong versions of, important files.
