Been a while since my C days and I am have a hell of a time getting IPLBoot to compile as it requires an old version of devkitPPC (r26).
https://github.com/seewood/iplboot#buil ... nd-vipergc
Following the instructions, I found version r26 of devkitPPC
here, pulled the latest libOGC and compiled it with devkitPPC r26, and then attempt to compile iplboot with devkitPPC r26 and my compiled libogc.
It fails to link stating usleep is undefined:

collect2: ld returned 1 exit status
I assume I am just missing a library. usleep is declared in devkitppc-amd64_26/amd64/devkitPPC/include/sys/unistd.h, but what library should it be in?
FWIW, I can compile the
example projects with latest devkitpro without any issues.

Ah I realized I could use the --verbose flag in addition to -v. Some more information:

More digging. I searched through all the symbols in all the libraries in my normal/latest devkitpro installation looking for where usleep was defined. Found it:
Code: Select all
find /opt/devkitpro -name '*.a' -exec bash -c "echo {}; nm --defined-only {} 2>/dev/null | grep usleep" \;
...
/opt/devkitpro/devkitPPC/powerpc-eabi/lib/libsysbase.a
usleep.o:
00000000 T usleep
So usleep is defined in usleep.o in libsysbase.a in the latest devkitpro version.
Edit: In devkitpro r26, libsysbase.a also exists but does not contain usleep.o. In fact, usleep is not defined in any library in r26...
Code: Select all
find /home/mike/projects/devkitppc-amd64_26 -name '*.a' -exec bash -c "echo {}; nm --defined-only {} 2>/dev/null | grep usleep" \;
find /home/mike/projects/devkitppc-amd64_26 -name '*.o' -exec bash -c "echo {}; nm --defined-only {} 2>/dev/null | grep usleep" \;
find /home/mike/projects/devkitppc-amd64_26 -name '*.so' -exec bash -c "echo {}; nm --defined-only {} 2>/dev/null | grep usleep" \;
What gives!?

I tried stealing usleep.o and nanosleep.o from the latest version and using them to link. It worked... in that it linked and compiled successfully. But after flashing my pico I get only a black screen. Not sure if the problem is those libraries or something else. Would like to get my build environment figured out so I can start eliminating variables...
Any advice is welcome.

OH YEA! Got it!
I miss-read the docs. version r26 of devKitPro is only required if you are compiling for the old qoob or viper mode chips which had limited space. Doesn't mater for PicoBoot. So you can just use latest devKitPro.
Getting it compiling was pretty easy after that. I'll be submitting pull requests for some of the required tweaks and do a write up.
One early observation is that I could not get a working IPL when compiling iplboot with gcc. clang worked though.
Thanks for rubber-ducking everyone
