ring0, i used to have one of those, simulators exist though, and catalina (lcc-based) and gcc. https://en.wikipedia.org/wiki/Parallax_Propeller The design philosophy of the Propeller is that a hard real-time multi-core architecture negates the need for dedicated interrupt hardware and support in assembly # Unlike a traditional multitasking single-processor interrupt architecture, the signal response timing remains predictable, and indeed using
<kof673>
the term interrupt in this context can cause confusion, since this function can be more properly thought of as polling with a zero loop time

<kof673>
not sure what current state is, i believe formerly max configuration was 16M RAM, some of that might be rom though...
<kof673>
that is not quite scheduling but, if you have 8 little cores, who needs interrupts lol
<kof673>
not sure what current state is :D nor if the p2 hardware is 'open' or not > As of 2014, Parallax is building a new Propeller with cogs that each will run at about 200 MIPS, whereas the current Propeller's cogs each run at around 20 MIPS

So, as my previous __konversation__ (get it, konversation is the KDE IRC client) with zid went, I had a problem with meaty skeleton in which "libk.a: error adding symbols: file format not recognized" happend
<mhsdeveloper>
*happened
<mhsdeveloper>
I figured out why it wasn't working! :-D
<mhsdeveloper>
Lemme get on via Konversation (if I can)

I fixed it by setting my env variables to the correct ones, I was compiling libk.a __not__ using `build.sh` because for some reason it wasn't freaking cooperating

Again, back
<kof673>
it means exactly what it says, canont find TerminalInit() (a function surely) and write() functions
<mhsdeveloper>
Right. Compiling with the rest of the stuff... don't know why it's erroring then
jcoding has joined #osdev
<jcoding>
hello?
jcoding has quit [Client Quit]
<kof673>
i'm not familiar with the tutorials, are you supposed to write them yourself, or are they included?
<mhsdeveloper>
They're included with meaty skeleton...
<kof673>
but which file/where? and why isn't such an object or libary getting linked in...
<kof673>
IME i believe you can compile all day long to objects with unresolved unreferences.........but when a binary is made, then it needs to find all the symbols so my understanding that is normal that libk.a (putchar() inside of it) builds fine, even if write() cannot be found
<kof673>
so it does not manifest until linking a binary
<kof673>
meaning, libk may be fine, unless it is supposed to have write()
<mhsdeveloper>
It's _clearly_ defined in include/nova/tty.h (it's included in nova/kernel.o [in Makefile it includes include/])
<mhsdeveloper>
Libk is supposed to have write...
<kof673>
.h is declarations, where is the code :D
<kof673>
ok, that helps
<mhsdeveloper>
In the libk.
<mhsdeveloper>
(the code is)
<kof673>
*unresolved references
<mhsdeveloper>
Oh, it isn't defined in the libk :-P
<kof673>
i mean 1) find whatever .c file has write() (and TerminalInit() ) 2) find what .o object files gets compiled for those 3) find why that .o file is not getting linked when building the binary (or e.g. should the .o be put inside libk.a, an archive)
<mhsdeveloper>
It's in arch/i386...
<mhsdeveloper>
tty.c
<kof673>
sure, now how does tty.c get compiled, does it make a tty.o object file?
d1rg3_ has quit [Ping timeout: 244 seconds]
<mhsdeveloper>
Real quick, in my arch/i386/make.config, I specified tty.h instead of tty.o (AARGH)
<kof673>
well, if it goes to a .a file, that should have errored out when not found or, linking directly against non-existent tty.o would have given a different error too.
<mhsdeveloper>
It never gets compiled when it runs into the error
<mhsdeveloper>
It also isn't in libk
<mhsdeveloper>
.a
<kof673>
i mean that presumably would've happened before building the kernel binary
<mhsdeveloper>
write... (get it?)
<kof673>
yes, and i don't know if it is supposed to be in libk, but you can add it there, or some other .a file, or link against the .o files directly. again, not familiar with the tutorials, what is proper

Ok
<mhsdeveloper>
I don't know how I would do that though...
<mhsdeveloper>
It's funny that Emacs has a built-in IRC client ;-D
<mhsdeveloper>
Lemme try the libk
<mhsdeveloper>
tty.c relies on vga.h which is part of arch/i386
<mhsdeveloper>
I don't think this is working...
<kof673>
"I don't know how" well it is using makefiles seemingly...so somewhere a makefile rule should be building tty.o perhaps, somewhere else libk.a is made invoking the "ar" command (or i686-ar whatever the toolchain is) ........and then somewhere the kernel binary gets linked against libk, -lk
<kof673>
the .a file is just an "archive" with a bunch of .o files inside it, is my understanding
<mhsdeveloper>
right.
<mhsdeveloper>
In the makefile it just cycles through the c files.
<kof673>
sure, so either it is building tty.o from tty.c or not, you should see it flyby when you type "make" or whatever....
<mhsdeveloper>
right... my computer screen is small so qemu makes it WAY too big to use
<mhsdeveloper>
did you check the link?
<kof673>
int SetColor(char color) void SetColor(int) it means what it says, two functions, with same name, but different function signature (return type and argument(s) type(s) )
<kof673>
so it does not know which to use
<mhsdeveloper>
:-P for some reason it keeps saying that setcolor's original return is void when i set the .c one to int, and when i set it to void it says that the .h one is int.
