Cannot run 3dsx application on a real 3ds

Hi, I've got an issue where I can't run my 3dsx application on a real 3dd, but it works in Citra. I'm using the 3ds guisprites example.

Add an ability to debug the "Unaligned relocation" error reason

Hello!
Recently I attempted to test a certain pile of libraries, HOWEVER, I got the "Unaligned relocation" error with totally no explanation WHERE it happens, WHICH part causes this error, etc. That's a pain!
So, in addition to #8, there is really a need to add an ability to debug the reason for the "Unaligned relocation" error, otherwise, it's absolutely confusing when an error happens, and there is totally no explanation for why it happens.

Troubleshooting Unaligned Relocation Error

I'm compiling a 3DS homebrew game and I'm getting "Unaligned Relocation" when it tries to build the .3dsx file from the .elf file. I'm able to build the .cia file and install it on the 3DS and it seems to run fine.

What is the reason for the tool failing with "Unaligned Relocation" and is there a way to troubleshoot what line of code is the problem?

Thanks!

[romfs building] skip dotfiles / error with no directory

Mentioned here, building the romfs for an application should not include dotfiles from GitHub, should they be present for whatever reason.

Furthermore, if the romfs directory does not exist it fails to build. This is the opposite of what happens on building a romfs using the switch tools.

tl;dr skip GitHub files and it can't build a romfs if the directory doesn't exist (and should successfully build like that of the switch tools)

Exceptions in 3dsx converted from ELF do not work as expected

I'm converting an ELF binary using exceptions to a 3dsx using 3dsxtool.
When running the ELF directly in Citra exhibits the correct behavior of the exception being caught,
but when running the generated 3dsx in Citra it crashes when the exception is thrown.
I'm using devkitARM r46 on Linux.

Test case.

Crash when running generated 3dsx

Hi,

I get a crash when running the generated 3dsx file on a real 3ds as well as in Citra.
I'm not sure if it's something I'm doing or some limitation in the 3dsx format.

It seems to be relocation related as it crashes at runtime when trying to get the address of a c++ member function pointer.

• No errors when running the 3dsxtool, but when I run 3dsxdump on the 3dsx file, it gives: "Cannot write segment data!"
• The elf file works fine, just the 3dsx file crashes.
• I tried creating a smaller test example with member function pointers, but that seems to work fine.

I've uploaded the just the test elf here (let me know if you need the smdh and romfs folder as well):

Is there anything I can do to help look into this?
Thanks,

(I don't know where to say this) I've compiled a 64-bit linux binary

Relocation to invalid address!
