Hi!
I want to port my virtual machine Nano to AROS.
Nano uses POSIX threads to run program parts parallel.

Programs for the VM can be compiled with the N compiler or
with the assembler. The N compiler has a inline assembler, so
both can be mixed.

Nano also has Flow, a GUI server.
Currently Linux and Windows are supported platforms.

The Linux x86_64 crosscompiler SDK hasn't a pthread.h include.
Is there a way to get a POSIX thread library for the SDK?

No, but the most commonly used pthread functions can be substituted with thread.library calls. Take a look at this page: http://aros.sourceforge.net/documenta ... opers/autodocs/thread.php

OK. Now I know where to look at.
Thanks!

Good luck! It would be great to have nano available for AROS.

Yep! Good luck!

I'm currently making changes to th Nano sources to make a build.

I made a make script:

#!/bin/bash
export CC=x86_64-aros-gcc
export AS=x86_64-aros-as
export LD=x86_64-aros-ld
export AR=x86_64-aros-ar
export RANLIB=x86_64-aros-ranlib
export STRIP=x86_64-aros-strip
./configure CFLAGS="-ffast-math -fomit-frame-pointer -O2 -s -D__AROS__" \
--host=x86_64-pc-linux-gnu \
LDFLAGS="-lthread"
make


GCC can't find the threads library on linking.
There isn't any libthread.a in my lib directory.
Where can I find it?


BTW Here is the project homepage:
http://www.jay-t.de/nano/index.html

Are you sure about compiling for x86_64? Currently i386 is the only supported architecture for ABIv0, and that's what everyone uses, including the distributions.
Also there's no libthread.a, only thread.library shared library. You have to include , declare struct Library *ThreadBase, and open/close the library with OpenLibrary()/CloseLibrary().

I'm adding now OpenLibrary () / CloseLibrary.

I have an include/libraries/thread.h
But not an include/proto/thread.h

If I understand it right I have to include a proto/ include
to tell the compiler to use a shared library.

Is that right?


About using x86_64 gcc: I want to check my build on Linux Hosted AROS. And I'm using a 64 bit Linux.

Yup, you need proto/thread.h, which will include clib/thread_protos.h for you. To me it sounds like you have an incomplete dev environment.

I copied the includes from the 386 SDK.
Now I'm including this:


#include <proto/exec.h>
#include <exec/libraries.h>
#include <dos/dos.h>
#include <proto/thread.h>


At the CloseLibrary() call, the compiler throws an error:

There are undefined symbols in 'nanoa':
U SysBase /home/stefan/sources/svn/nano-vm-3.0.22-new-aros/nano-vm-code/lib/mem.c:1166
make[2]: *** [nanoa] Error 1


Where is SysBase declared? Is it of struct Library used in CloseLibrary() ?
