Re: Help, Build Visopsys Failed

Did you forget to change the end of the function (that second bit of code I pasted)?

Re: OS Development Tutorial for Beginner

There's a collection of links and things on the visopsys.org site https://visopsys.org/osdev/.

The best overall resource today is probably OSDev.org https://wiki.osdev.org/Main_Page

Re: Help, Build Visopsys Failed

Thanks for helping me work out these problems :-D The latest error is basically the inverse of the first one. Edit the top of the kernelApi() function to add statusLo and statusHi: void kernelApi(unsigned CS __attribute__((unused)), unsigned *args) { // This is the initial entry point for the kernel...

Re: Help, Build Visopsys Failed

OK, now I guess my basic C++ runtime support isn't complete enough for your compiler's tastes. Looks like maybe your C++ compiler is using the C++14 standard by default, maybe (I'm not a C++ expert). Can you change the C++CODEGEN line in Makefile.include to read as follows?: C++CODEGEN = ${CODEGEN} ...

Re: Help, Build Visopsys Failed

Hellow meowsoft, and welcome This is a bit of a weird one. I can see why the assembler is complaining, but I don't know why you see this error, and I don't. Is your gcc using some different assembler than the standard gas maybe? Anyway, can you try changing the _syscall() function in src/lib/libc/_k...

Re: My experiences with Visopsys install on QEMU virt disk

Hi Ron, Then I thought I could be tricky and use wget to grab a README file from an ftp server, since ftp doesn't use SSL. Normally, a file can be grabbed via wget with this syntax: wget ftp://ftp.someftpsite.org/somefile The program did start a conversation (that I could observe via the host machin...

Re: My experiences with Visopsys install on QEMU virt disk

When I type host www.visopsys.org , I get the address response OK. Here's a pic: DNS looks alright there. One reason I didn't develop the wget program further is that it doesn't have SSL support yet, and there's not much plaintext HTTP out there on the web nowadays. Which is also true of visopsys.o...

Re: My experiences with Visopsys install on QEMU virt disk

Hi Ron,

Well, I'm glad that things seem to be working now for you (even if I lament the missed opportunity to debug these maddening interrupt snafus).

If you open up a command prompt, and try something like "host visopsys.org", does it give any error info?

Re: Won't finish booting

Hi hooptydoopty The problem that Ron was having over in the Visopsys forum seems to have been transient, and I can't reproduce it either. I started looking at your description of your system. This 'Bolton' chipset triggered a memory, and a search of earlier posts turned up this: https://visopsys.org...
