Build failure on modern devkitPro (libogc 2.x/3.x) - Undefined references and header conflicts

[mctominay8]

Hello,
I am attempting to compile the launcher on macOS Sonoma (Intel) and via the official devkitpro/devkitppc:latest Docker image, but the build fails due to several incompatibilities with the current devkitPro environment.
Main issues encountered:
Multiple Definition of inet_ntop / inet_pton: Conflict between libogc (v3.0.3+) and libwiisocket provided by the install-libs.sh script.
Undefined reference to gettime and diff_msec: These functions seem to be missing or named differently in the current libogc headers, causing linking errors in main.c, shutdown.c, and update.c.
Missing Headers: Compilation of runtime-ext fails because io/fat.h and io/fat-sd.h are not found in the standard include paths of the latest libfat-ogc.
SSL Certificate Errors: The install-libs.sh script fails on macOS because wget cannot verify the GitHub certificates without the --no-check-certificate flag.
Environment:
OS: macOS Sonoma 14.x (Intel) / Docker (Debian Bookworm)
devkitPPC: r45 / GCC 15.2.0
libogc: 2.x / 3.x
Could you please update the Makefile and the source code to support the latest devkitPro releases, or provide a pre-compiled .dol in the Releases section?
Thank you for your work on Retro Rewind!

Unfortunately, libogc 3 introduced breaking changes regarding its threading implementation, and also introduced some socket functions that directly clash with the ones we use in libwiisocket. Fixing this is non-trivial, because the libogc socket implementation is not thorough enough to support libcurl.

Once the current version is released into beta channels we will address this.

Thanks for the clarification regarding libogc 3.

Since the current devkitPro environment is incompatible, would it be possible to temporarily provide a pre-compiled .dol? at the moment I’m blocked by the toolchain incompatibility.

Even an older build would be extremely helpful.

Pre-compiled binaries are available in the Retro Rewind discord, if you go to the rr-announcements channel and scroll up a bit to the open beta announcement posted on the 5th Feb. It should have all the files you need.

As an aside, once we hit the first stable release we can start producing GitHub releases as well.

Since it sounds like you're already trying to use docker, a workaround for now if you just want to build it locally is you can change .github/docker/Dockerfile's devkitppc version to one that works and use that image to build the channel. I tested it with 20251231 and that works.

diff --git a/.github/docker/Dockerfile b/.github/docker/Dockerfile
index a437751..e1716dd 100644
--- a/.github/docker/Dockerfile
+++ b/.github/docker/Dockerfile

 # Dockerfile for the bare environment RR needs (dkp tools & necessary libraries installed into /opt). Used in CI
 
-FROM devkitpro/devkitppc
+FROM devkitpro/devkitppc:20251231
 
 COPY install-libs.sh ./

Then build it using the image

docker build . -f .github/docker/Dockerfile -t retrorewind
docker run --rm -v $(pwd)/:/rr -w /rr --name retrorewind retrorewind make release

Now build/release has the necessary files.
