Linking errors on Ubuntu 22.04

[vanfanel]

Hello there,

I'm having a hard time building 64doom, latest GIT code.

I have installed both the toolchain and latest unstable libdragon branch. 64doom compiles fine, but on the linking phase I get:

/opt/libdragon/bin/n64tool \
        --header /opt/libdragon/mips64-elf/lib/header --title DOOM --toc --output DOOM.z64 DOOM.bin --align 8 DOOM.sym --align 8 DOOM.msym --align 16 rom.dfs
ERROR: Cannot open /opt/libdragon/mips64-elf/lib/header for reading!
ERROR: Header file '/opt/libdragon/mips64-elf/lib/header' is too small (minimum is 4096 bytes)

Any idea on what am I doing wrong, please?

I believe it's related to this change: https://github.com/DragonMinded/libdragon/issues/158

Still can't get it to build myself though.

[Bobbar]

I was able to get a ROM working for Ares by using the trunk branch of libdragon instead of unstable. I'll test it with real hardware later.

[Bobbar]

I confirmed that the ROMs work on real hardware.

For posterity: I started with a fresh WSL2 Ubuntu image then installed unstable libdragon. That didn't work for the reasons above. So then I switched to the trunk branch and just ran the build.sh again, and that finally worked for me.

Cheers

@Bobbar Thanks for trying and for the trunk branch suggestion. However, on GNU/Linux, using the trunk branch of libdragon, I get this upon building 64doom:

/opt/libdragon/bin/mips64-elf-objcopy DOOM.elf DOOM.bin -O binary
/opt/libdragon/bin/n64sym DOOM.elf DOOM.sym
/opt/libdragon/bin/n64dso-msym DOOM.elf DOOM.msym
make: /opt/libdragon/bin/n64dso-msym: No such file or directory
make: *** [Makefile:109: DOOM.z64] Error 127

...and that's because n64dso-msym does NOT exist on the trunk branch at all, at least on GNU/Linux.

So, what is going on? 64doom only builds on whatever is used on Window$ to build GNU/Linux stuff?

[Bobbar]

Hmm. It very well may be because I installed unstable first, then installed trunk on top of it without clearing the /opt/libdragon directory. So I'm probably using the n64dso-msym that was compiled from unstable.

@Bobbar Ah yes, that did it, I could finally generate DOOM.z64, thanks!

However, this is still an issue, having to mix two different libdragon versions doesn't look quite right...
