Build errors on powerpc macos

Questions & Answers
1

I've tried to build racket on two different powerpc macs and so far have not been successful. Is there a minimum macos or xcode version that I need? Should I build BC or CS variants?

I'm building from the official racket-8.13-minimal-src.tgz distribution.

First machine:
Powerbook G4 running 10.3.3
Numerous errors here with both CS and BC, so I think the OS is probably just too old.

Second machine:
Mac mini G4 running 10.4.11
GCC version 4.0.1
Ran configure with default options
Build fails with a libtool error:

Although I've built on a PowerPC Mac relatively recently, it was with Mac OS 10.5. I vaguely recall that I had to upgrade to 10.5 years ago because 10.4 was too old to be practical, but I'm not sure I remember correctly.

3

I can probably install 10.5 on one of my machines. It is good to have confirmation that it should work. I'll update this thread when I get a chance to try it.

4

I'm almost there. Racket-minimal builds on Mac OS 10.5. I also have the replacement openssl libs from libs/racket-ppc-macosx-3/racket at master · racket/libs · GitHub.

My issue now(I think) is that the I don't have valid CA certificates for openssl. I tried copying certs from a linux box and putting them in /System/Library/OpenSSL/certs but it made no difference. I also tried setting SSL_CERT_DIR. I'm not sure where this openssl library is looking for the certs. I realize this is not a Racket issue but anyone know the solution here?

I forgot about that problem. My solution here has been to set the PLT_PKG_SSL_NO_VERIFY and GIT_SSL_NO_VERIFY environment variables.

Those environment variables did the trick. I now have racket built and running on a Mac Mini G4! Thanks for all the help.
