Conversion errors in ipc.h

[PeregrineZ]

I was using libnx to compile a test executable for the Switch (thanks for this, by the way!), when I ran into some errors related to invalid conversions in ipc.h while compiling. Here's the error:

aarch64-none-elf-g++ -o C:/Users/mason/source/repos/Switch/Switch/Build/Main.out -LC:/devkitPro/libnx/lib -IC:/devkitPro/libnx/include -lnx -static -static-libgcc -static-libstdc++ Main.cpp <

I seemed to fix these errors by casting armGetTls() to (u32*) in each occurrance, and by naming the mentioned structs "raw" and casting r.Raw to (struct raw *). Here are the lines:

Lines 109, 209, 262, 297:

u32* buf = (u32*) armGetTls();

Lines 279-283, 312-316:

struct raw {
    u64 magic;
    u64 result;
    u32 object_id;
} *raw = (struct raw *) r.Raw;

Feel free to change these, I'm kind of a novice at C/C++, so there might be some unintended consequences haha.

Keep up the great work!

Which devkitA64 release are you using?(And what libnx commit)

[PeregrineZ]

I'm using devkitA64 Alpha 5 and the latest libnx commit (1fccd4a).

[yellows8]

Did you modify the Makefile for this app at all? EDIT: Are you even using the example Makefile?

[PeregrineZ]

Nope. I downloaded the zip, ran make and make install, and ran a test build.

[yellows8]

Are you running make with an example from switch-examples, or what?
