I was interested in the latter, but they end up depending on a large number of environment variables, which are traditionally sourced through $KOS_BASE/environ.sh. Although it’s not really a big issue to have all those environment variables, I wondered whether there was a cleaner approach.https://blog.jpeach.org/posts/2023/05/homebrew-tricks-for-the-dreamcast-toolchain/Sun, 21 May 2023 11:08:46 +1000https://blog.jpeach.org/posts/2023/05/homebrew-tricks-for-the-dreamcast-toolchain/I’ve spent some time working on a Homebrew tap for Dreamcast development tooling, and wanted to write a little about the tricks I used in creating formula to install the Dreamcast compilation toolchain. First, the Dreamcast toolchain is actually build and installed by the dc-chain package from the KallistiOS repository. dc-chain has 3 phases - download, unpack and build. The download phase is done by the download.sh script, which downloads the source archives of the toolchain components (gcc, binutils, newlib, gdb) for SH4 and ARM architectures.https://blog.jpeach.org/posts/2023/05/dreamcast-development-setup/Wed, 17 May 2023 09:29:23 +1000https://blog.jpeach.org/posts/2023/05/dreamcast-development-setup/Way back in the last century, I bought a Sega Dreamcast. One of the reasons that I like it (apart from some great games), was that there was a burgeoning homebrew development scene for it. I went and bought the various bits of hardware I thought I needed to get going, but ended up never doing anything, and it all sat in storage for 20 years. Recently, I unpacked everythying and decided to figure it all out.
