Basically this is in the linux kernel: This is what mmap does in linux... static inline unsigned long do_mmap(struct file *file, unsigned long addr= , =09unsigned long len, unsigned long prot, =09unsigned long flag, unsigned long offset) { =09unsigned long ret =3D -EINVAL; =09if ((offset + PAGE_ALIGN(len)) < offset) =09=09goto out; =09if (!(offset & ~PAGE_MASK)) =09=09ret =3D do_mmap_pgoff(file, addr, len, prot, flag, offset >> PAGE_S= HIFT); out: =09return ret; } This is what mmap2 does: andstatic inline long do_mmap2( =09unsigned long addr, unsigned long len, =09unsigned long prot, unsigned long flags, =09unsigned long fd, unsigned long pgoff) { =09int error =3D -EBADF; =09struct file * file =3D NULL; =09flags &=3D ~(MAP_EXECUTABLE | MAP_DENYWRITE); =09if (!(flags & MAP_ANONYMOUS)) { =09=09file =3D fget(fd); =09=09if (!file) =09=09=09goto out; =09} =09down_write(¤t->mm->mmap_sem); =09error =3D do_mmap_pgoff(file, addr, len, prot, flags, pgoff); =09up_write(¤t->mm->mmap_sem); =09if (file) =09=09fput(file); out: =09return error; } So what it looks like to me is that mmap2 expects an offset that's alread= y=20 page-aligned (I'm not sure if this is the right way to say it), where mma= p=20 doesn't. the FreeBSD code in the linuxulator basically just takes the off= set=20 that is passed in with the linux mmap, and uses that to call FreeBSD's mm= ap=20 (the kernel version, not the one called from userland). So basically I'm=20 kinda stuck as to what to do to implement linux's mmap2. The only thing I= can=20 think of is to implement a FreeBSD "mmap2" that basically assumes that th= e=20 offset passed in is already page aligned or whatever, and just uses it, a= nd=20 then have linux_mmap2() just call the FreeBSD mmap2(). Any ideas?

Since linux passes the offset with a 32-bit long, rather than a 64-bit off_t like we do, they need to do this in order to be able to map offsets larger than 4GB into a file.

I guess ctob does what I need it to. I think that's probably why it still wasn't working yet... I think it also has to be page aligned before you pass it in though, I have to look at linux's do_mmap_pgoff() (I think that's the right function name) to see if it's expecting an already page-aligned arg, or if it's aligning it before it uses it.

The name implies that do_mmap_pgoff() takes page-shift'ed args. An offset specified as a page-shift is page-aligned by definition. Eg, when you call ctob(pgoff) this turns out to be (pgoff << PAGE_SHIFT) bytes.

This has been on the list before, but the answers seem incorrect, as far as I can tell. The base problem is that acroread (version 4.05) is linked with older versions of most of the expected libraries. Installing linux_base-7 get you newer libs, and you will have to find older libs and copy them into you compat/linux/lib for *every* file. The real problem, as I see it, is that there is no COMPAT_LINUX_6 or similar option. The rpms refuse to install linux-7 on top of linux-6, so all needed libs and files will have to be hand copied over, which is really boring. :( Also, I cannot get acroread to use the ld.so.cache; instead, I need to set LD_LIBRARY_PATH. any ideas why? I've seen people on this list saying that acroread works fine with their linux_base-7. This is not true out of the box, there must be a catch, no?

Sorry for jumping the trigger. The acroread4 port will not install with linux_base-7 without tweaking, something I didn't notice, so it was never updated...

It seems to be installed now, although I'm getting a bunch of linux: 'ioctl' fd=6, cmd=0x7201 ('r',1) not implemented complaints. Also, I didn't succeed yet in installing something useful, as it seems the MS Office CD I have here is an update CD or something. I'll look for another one and let you know how it works. Karel.

Although I finally managed to install MS Office '97, trying to run Office programs mostly results in linux: syscall ptrace is obsoleted or not implemented (pid=2865) and wine quits. Karel.
