Your test program.
Assuming you’re starting from the PNG example Makefile, find this portion of the Makefile:
example.elf: $(OBJS) romdisk_boot.o
	$(KOS_CC) $(KOS_CFLAGS) $(KOS_LDFLAGS) -o $@ $(KOS_START) $^ -lpng -lz -lm $(KOS_LIBS)
Change it to look like this:
example.elf: $(OBJS) romdisk_boot.o
	kos-c++ -o $@ $^ -lpng -lz -lm
If you’re not using a romdisk, get rid of the romdisk_boot.o stuff too, of course.

Also, where in the Makefile does it try to link with $KOS_CC?

Compile and link with kos-c++ in your Makefile, rather than $KOS_CC or whatever it is your makefile is currently using.
The issue here is that you’re not linking in the standard C++ library at all, which causes problems if you try to use any of it.

So I'm in the process of converting code over from c to c++.(The code was
based of the PNG example.)
Currently I'm trying to use functions from the standard library like
#include<vector>, #include<string> and #include<fstream>.
When I try and compile the program in Cygwin. I get these errors coming up
and interrupting the process.
The errors I'm getting are in this block of text it returns back to me:

Ah... Now that I see your post on another forum asking the same question, it makes a bit more sense.
As was said over on that other forum, you either need to use a translucent or punch-thru polygon and have the background have alpha to make it transparent. To do this, you’ll need to use a PNG (or some other format that supports alpha), which if you’re using the image you posted over on that other forum, then you’re already doing. Just make the background transparent in your image editor instead of white.

I’m guessing your texture itself has a white border around whatever you’re drawing (i.e, it’s not actually 512x512 pixels in size, but you’ve extended the image by just resizing it and filling that in as white)?
If so, what you need to do is adjust the u and v coordinates on each vertex. These two values are what portion of the texture you want to display. The left and top of the texture correspond to 0.0 of u and v respectively, whereas the full extent of the texture (in this case 512 pixels over from the left and 512 pixels down from the top) correspond to 1.0 of u and v respectively.
If your texture is actually 320x240 (for instance), then you’d want to adjust the u and v on the bottom and right side vertices (i.e, everything where you have 1.0) to be (320.0f / 512.0f) and (240.0f / 512.0f).
Hopefully I’ve guessed what your issue is correctly and that helps understand the process.

I've been learning how to program with KOS. And currently I can display
images and
even move them around. But what I'm trying to figure out is how can I
display the
image without the white border behind it. Here's my current code for
drawing one of the graphics:
void draw_ground(void) {
 pvr_poly_cxt_t cxt;
 pvr_poly_hdr_t hdr;
 pvr_vertex_t vert;
 pvr_poly_cxt_txr(&cxt, PVR_LIST_OP_POLY, PVR_TXRFMT_RGB565, 512, 512,
ground_tex, PVR_FILTER_BILINEAR);
 pvr_poly_compile(&hdr, &cxt);
 pvr_prim(&hdr, sizeof(hdr));
 vert.argb = PVR_PACK_COLOR(1.0f, 1.0f, 1.0f, 1.0f);
 vert.oargb = 0;
 vert.flags = PVR_CMD_VERTEX;
 vert.x = gx;
 vert.y = gy;
 vert.z = 1;
 vert.u = 0.0;
 vert.v = 0.0;
 pvr_prim(&vert, sizeof(vert));
 vert.x = gx + size;
 vert.y = gy;
 vert.z = 1;
 vert.u = 1.0;
 vert.v = 0.0;
 pvr_prim(&vert, sizeof(vert));
 vert.x = gx;
 vert.y = gy + size;
 vert.z = 1;
 vert.u = 0.0;
 vert.v = 1.0;
 pvr_prim(&vert, sizeof(vert));
 vert.x = gx + size;
 vert.y = gy + size;
 vert.z = 1;
 vert.u = 1.0;
 vert.v = 1.0;
 vert.flags = PVR_CMD_VERTEX_EOL;
 pvr_prim(&vert, sizeof(vert));
}
any help figuring this out would be appreciated.

If you’ve followed that tutorial, wget is already installed (as it has you install it when you install cygwin initially).

Most people won’t use many of the ports at all (zlib, libpng, libjpeg, and liboggvorbisplay/libtremor are probably the extent of what most people use), so there’s little reason to build everything.

Thanks for your advice, How would I go about installing curl or wget?

You either need curl or wget installed on your system. If you have wget, then you need to open up the configuration file for kos-ports (the file is called config.mk in the root of the kos-ports directory) and comment out the line that says 
FETCH_CMD = curl --progress-bar -O
and uncomment the one underneath it that says
FETCH_CMD = wget --progress=bar
Also, if you don’t have python installed, you’re going to have to go down to the bottom of that file and change the line that says
VALIDATE_DISTFILES = true
to be false instead.
Not to be mean, but I would like to point out that the kos-ports README does mention both of these things. ;)
Also, I don’t necessarily recommend running the build-all.sh script unless you REALLY think you’re going to need all of the ports. Most people won’t use many of the ports at all (zlib, libpng, libjpeg, and liboggvorbisplay/libtremor are probably the extent of what most people use), so there’s little reason to build everything.

You should have Curl installed on your system.

Thanks for responding. The tutorial I'm trying to use is this one:

And I'm getting stuck on setting up the dreamcast toolchain and development
environment . Here's the link to the part I'm stuck on.

I'm currently using Cygwin on a PC to do this tutorial. I feel like I
followed all the steps correctly, but maybe I missed something? Any help
would be greatly appreciated .

First of all, what tutorial are you following, specifically? Also, what platform are you trying to do this on (Linux, Mac, Windows/Cygwin, something else more exotic)?
That particular error is complaining that it cannot find your Dreamcast-targeted compiler. That implies that either it hasn’t been built or that it is in a different location than where the environ script thinks it is.

I'm trying to follow tutorials on how to setup kallistios. I start running
into problems when I need to work with the Environ.sh
file. When I run the command "source environ.sh" I get the following error
/home/YouPeople/dc/kos/utils/gnu_wrappers/kos-cc: line 34:
/opt/toolchains/dc/sh-elf/bin/sh-elf-gcc: No such file or directory
It seems like I'm missing a file for it, even though I downloaded this
through GIT. Is there a step I missed? Or something else I need to download?
PLEASE HELP!

Nevermind, everything is statically linked isn't it - so what I'm asking
for doesn't make any sense! Ignore me :)

OK, so I've made some progress and have successfully compiled an SDL 2
sample - it runs and gives me a black screen but as I only have an SD card
reader and no coders cable I have no way to debug that...
Anyway, one thing that I can't figure out is that in the SDL 1.x port if
HAVE_OPENGL is defined a function called glKosGetProcAddress is used - I
can't find any reference to that function anywhere and I'm pretty sure it
doesn't work if you compile with that setting.
So, what would be the equivalent of GetProcAddress on Kos? dlopen doesn't
seem to exist, does Kos have something similar?

Those are fairly easily explained...
Environment variables are not supported in KOS, so getenv/setenv don't actually exist in libkallisti. Don’t define HAVE_GETENV and HAVE_SETENV in your SDL_config_dreamcast.h file. SDL has a built-in implementation that will be compiled in if you don’t define those.
The second one should go away if you link with libm.

Thank you! I've disabled DYNAMIC_API on the DC, and I realized that
__DREAMCAST__ is not what I should be checking for, but _arch_dreamcast
(facepalm).
Now I'm down to a couple of atomic-related SDL references, and stuff like
this:
/home/lukeb/Dreamcast/kos-ports/SDL2/build/SDL2-2.0.4/libSDL2.a(SDL_getenv.o):
In function `SDL_getenv':
/home/lukeb/Dreamcast/kos-ports/SDL2/build/SDL2-2.0.4/src/stdlib/SDL_getenv.c:182:
undefined reference to `_getenv'
/home/lukeb/Dreamcast/kos-ports/SDL2/build/SDL2-2.0.4/libSDL2.a(SDL_stdlib.o):
In function `SDL_atan2':
/home/lukeb/Dreamcast/kos-ports/SDL2/build/SDL2-2.0.4/src/stdlib/SDL_stdlib.c:48:
undefined reference to `_atan2'
Which I'm guessing is down to me not linking a KOS library or something?
I'll take a look later when I find time. Thanks again!

 From what I can tell, SDL2 wants SDL_dynapi defined for all platforms.

Thanks OK, I just wanted to make sure that what I was doing in the makefile
wasn't obviously wrong... I'll keep digging! Thanks!

Unfortunately, I have no idea why you’d be having that particular issue off the top of my head. It looks like you’re compiling in the SDL_render.c file into your library, which is where those functions are implemented, so I don’t really know...
The only thing I can guess is that somehow you’re picking up an old version of the library where you didn’t compile that in or something? Try rebuilding the entire library and then the program again?
I really know next to nothing about SDL2, which I suppose doesn’t help here...
