OK, here's the issue, I'm being told be some forum members that my ctrulib must be outdated because I can't get one of the code examples to compile. I have redownloaded ctrulib and rebuilt it several times but it isn'n making any difference. Can someone tell me if I'm missing a step -- Download ctrulib from here -- https://github.com/smealum/ctrulib drop into devkitpro folder like so -- /opt/devkitpro/default.elf /opt/devkitpro/devkitARM /opt/devkitpro/examples /opt/devkitpro/include /opt/devkitpro/lib /opt/devkitpro/libctru /opt/devkitpro/libgba /opt/devkitpro/libmirko /opt/devkitpro/libnds /opt/devkitpro/maxmod_license.txt open terminal and cd to libctru... MacMini: spinal$ cd /opt/devkitpro/libctru and build... MacMini:libctru spinal$ make make: `/opt/devkitpro/libctru/lib/libctru.a' is up to date. Now, is there a next step or isn't there, because this is making no difference to me being able to try the audio example. Thanks.
