9vx on x86-64

9vx on x86-64

[Russ Cox]

9vx now builds and runs on Ubuntu Linux x86-64,
and hopefully other Linuxes as well.
It also runs gs and ape/psh correctly.
I haven't built new binaries nor a new distribution.
Soon; perhaps tomorrow.

I've got a patch at this point that gets it to build on FreeBSD/amd64,
but it dies in the trap handler (surprise, surprise). There are a
couple other things I've added / plan to add shortly. Russ, should I
just keep sending patches your way?

Pulled latest sources from mercurial, not working for me. I can see a
window openning and immediately see it crashing
I am using the latest 9vx on old distribution, just replaced the exe.
Compiles fine on a Sabayon 3.5.1 x86_64

9vx panic: boot process died: sys: trap: page fault pc=0x00001020
aborting, to dump core.

It seems a little odd that the log starts with
a partial word.  It is posible that if you did

9vx -PSX >log 2>&1

that somehow the fd offsets for 1 and 2 are
not being maintained properly
(I don't understand it, but I've seen it).

Sometimes it works better to do

9vx -PSX 2>&1 | cat >log

I just executed 9vx -P -S -X -r <path of dist 0.12> -u glenda

and pasted what was written on the linux console.

> 9vx -PSX 2>&1 | cat >log
this creates a log of 138 MB :( (19MB gzipped)

However, I think I solved it without actually solving it,
gcc flags changed from -g -03 to -g,
it works like a charm

It seems not working on LFS64 (pure-64 linux.from scratch)

It looks like you edited the VX32_CC line to say gcc -m64.
That's wrong.  $(VX32_CC) is supposed to be an i386 ELF compiler.
You should be able to compile just fine using gcc -m32.
If your host compiler can't do -m32 then you need to install
the vx32-gcc from the sources on the vx32 home page.

19 MB gzipped doesn't sound so bad.
Can you send it to me (not to 9fans)
as an attachment, or put it up somewhere
that I can fetch it from?

That's scary.  Can you send the output of "gcc -v"?

Thanks.
