Im trying to render a model using citro3d and im getting this:

What rule do i add to the makefile?

Try doing make clean and then make

Try doing make clean and then make

Nope, this did not work.

If you are trying to compile this you should only need the lates devkitpro with updated citro3d lib from the next branch (not the master one) fron the gitub repository

But if you are using a modified version of the example we need the full source code (and some info on your compiler enviroment and toolchain) to be able to give you some hints.

I have the latest Devkitpro and ctrulib. I am using a modified textured_cube example but the makefile is intact. I have the .obj file in the data folder.

the data folder is to build a romfs from where to load resources at run time. Reading the error seems the linker needs that file at compile time but don't know how to handle the obj extension.

I'm writing homebrew, and I'm currently working on adding a media player to my program. But I don't know where to start. Anyone know how to play wav mp3 and or mp4 files? I'm coding in c++

I've got gdb working and can use VS Code to attach and debug my test app, but is there a way to attach before the app launches so I can debug from the start?

Not atm, and it'd be too complicated to implement properly.

Also a neat thing I found is that you can pass 80 to APT_SetAppCpuTimeLimit and it'll work but it breaks the luma menu and hardlocks the 3ds once
you enter the button combo.

Does it does that with 8.0 (and 8.1) ?

 

[TarableCode]

I know it did on 8.0, didn't try it on my n3ds or on any other version yet.
I just updated my 2DS luma to 8.1 last night so at some point tonight I'll try it again, also maybe trying 79% and seeing if that lets the menu work.

Another thing I have no idea how to do. Is delete a folder, and no I don't mean rd, because that only deletes empty directories. I saw something in the ctrulib documentation, it was something along the lines of fs_deleteDirectoryRecursively but I couldn't figure out the syntax. I'd blame c++ for not natively knowing how to do this, but that wont accomplish anything. So, anyone know what to do?

Doesn't work so far, can't get the ffmpeg-configure3ds script to run properly, gives me a long list of errors in bash.

My bottom screen is flickering, how to fix it?

I am using the following void to set a background color to the buffer:

void test(u8* screen, int color)
{
    int width = (screen == TOP_SCREEN) ? SCREEN_WIDTH_TOP : SCREEN_WIDTH_BOT;
    for (int i = 0; i < (width * SCREEN_HEIGHT); i++) {
        *(screen++) = color >> 16;  // B
        *(screen++) = color >> 8;   // G
        *(screen++) = color & 0xFF; // R
    }
}

And this to set it:

u8* fb = gfxGetFramebuffer(GFX_BOTTOM, GFX_LEFT, NULL, NULL);

test(fb, RGB(255, 0, 0));

UPDATE: Got it fixed by adding gfxSetDoubleBuffering(GFX_BOTTOM, false); to it.

Thanks.

That will work fine for this simple case. But at some point you are going to want to use double buffering. A better solution would be to call
gfxGetFramebuffer each time so that you get the correct buffer. Because you were only calling
gfxGetFramebuffer once you were only updating one of the buffers. The flickering was caused by the other buffer that was never being updated.

Does it does that with 8.0 (and 8.1) ?

Here's what I've noticed, the rosalina menu works fine with APT_SetAppCpuTimeLimit at 30, and beyond that it works less and less.
At 60% it's dropping input and at 80% it doesn't register anything at all afaik.

Edit:
The weird thing is sometimes thread creation fails, and I don't know why and as far as I've seen there's no error code.

Ignore the messy code, it's all kludged to approximate what I'm working with on my other project.
It does seem to increase conversion speed, but sometimes thread creation fails.

Pastebin link because the code tag ignores whitespace...

I'm changed the menu thread priority between 8.0 and 8.1, is there any difference between the two versions?

 

[TarableCode]

I didn't notice any, but that's just from what I remember before I updated to 8.1.
Probably the better way to do this would be to keep the cpu time limit at 30% until it's time for the thread to do work.

I don't understand how to use any of the FS and FSUSER functions in libctru. There is no documentation. Although let me specify, there is documentation on things like the syntax, but there is no explanation on what that syntax is. I want to check if a directory exists and if it does delete it.

Here's how I'm deleting the directory:
FSUSER_DeleteDirectoryRecursively(ARCHIVE_SDMC, "sdmc:/3ds/testFolder");
though, this doesn't work because the second argument is a const char, not a "FS_Path".
So I look up the documentation on FS_PATH, which tells me nothing.
I figure: I'll come back to it later, now let's see how to test if a directory exists.
There doesn't seem to be a function specifically for that but I figure I can make it work. I found FS_PathType which seems to give an int that tells you 0 for invalid 1 for empty etc. But it doesn't say in the documentation how to tell FS_PathType what path you want to specify. So I assume FS_PathType isn't a function but rather some kind of struct, but that only makes me more confused.

I need some serious explaining about FS in libctru. Or if someone can send me examples (and I don't mean link me to peoples GitHub repo's or anything like that, I mean actual examples).

FS_Path is a struct and you can define it like this

   FS_Path dirPath = (FS_Path){PATH_ASCII, 8, "/mydir/"};

The second value is the size of the path string.

But why don't you use common C functions to handle directory? You can check if a directory exist with something like this:

#include <dirent.h>
#include <errno.h>

---

DIR* dir = opendir("mydir");
if (dir)
{
   /* Directory exists. */
   closedir(dir);
}
else if (ENOENT == errno)
{
   /* Directory does not exist. */
}
else
{
   /* opendir() failed for some other reason. */
}

Note: not tested, just taken from the net

because libctru has a function to delete a folder recursively (or in other words it can delete non-empty folders). C++ does not natively know how to do this. And I don't want to use the 'boost' system.

so I tried this code:

FS_Path testDir = (FS_Path){PATH_ASCII, 20, "sdmc:/3ds/ROT_Data/"};
FSUSER_DeleteDirectoryRecursively(ARCHIVE_SDMC, testDir);

it doesn't work... there aren't any compiler error's but it doesn't work. Although a small side note is, the starting { in the first line has the red line under it in visual studio and says: expected an expression.
Any ideas?
