Still sounds fantistically fun. Maybe you can point me in the right direction to write PalmOS programs (.prc's right?).
I have some goofy ideas for things to write for my Treo. jonathan On 5/24/07, sinisa marovic <[EMAIL PROTECTED]> wrote:
I'm afraid I will have to dissapoint you: it will be only isapc with no networking or other fancy devices. Main goal is the ability to run dos games. I do not know how familiar are you with PalmOS developer support. It is poor, gcc lack many important functions that have to be written from scratch. When I ported dosbox (which is written in c++) I realized that there is no support for vectors, iterators, namespaces etc, so I had to write many operators myself. The biggest problem with QEMU is that it uses signals a lot, and, guess what, PalmOS has no support for signals _at_ _all_. I found a way to get things going without them for now, but this has it's drawbacks. I will have to think about something better later on. ----- Original Message ---- From: Jonathan Kalbfeld <[EMAIL PROTECTED]> To: qemu-devel@nongnu.org Sent: Thursday, May 24, 2007 11:18:48 PM Subject: Re: [Qemu-devel] Porting QEMU to PalmOS One definite plus with having QEMU for PalmOS is the ability to run things like OpenVPN (even if slow) and connect to a VPN back-end. As is, I use OpenVPN tunnels to link up my QEMU machines on Solaris. jonathan On 5/23/07, Wolfgang Schildbach < [EMAIL PROTECTED]> wrote: > > Try compiling as position-dependent (i.e. not PIC) code.
