ld64-97 appears to be opportunistically linked to the openssl port on PPC Mac OS X, Tiger

[ballapete (Peter "Pete" Dyballa)]

When I try to upgrade any port that is built with GCC 4.2 config.log will contain something like this:

configure:3992: /opt/local/bin/gcc-apple-4.2 -pipe -Os -arch ppc -I/opt/local/include -I/opt/local/include/db48 -L/opt/local/lib -Wl,-headerpad_max_install_names -L/opt/local/lib/db48 -arch ppc conftest.c  >&5

The reason is here:

No /opt/local/lib/libcrypto.1.0.0.dylib.

I created a sym-link /opt/local/lib/libcrypto.1.0.0.dylib pointing to /opt/local/lib/libcrypto.1.1.dylib. /opt/local/libexec/apple-gcc42/gcc/powerpc-apple-darwin8/4.2.4/ld seems to work until now …

/opt/local/lib/libcrypto.1.0.0.dylib is part of openssl. As you are well aware, openssl was just updated.

Not many people use Tiger, so nobody noticed that updating openssl would break the compiler.

It's kind of a miracle that the openssl 1.1.1 library works -- it's just luck that it does, because it is binary incompatible with openssl 1.0.x.

Something needs a revbump -- either ld64-97 or perhaps apple-gcc-4.2. I'm not sure which one yet, as I haven't tried updating Tiger until all this openssl 1.1.1 dust settles, and we identify better all the broken ports. Updating Tiger is a project that I don't want to spend weeks on.

If updating openssl broke the functional compilers on Tiger, that will be a fun project :> Have to re-bootstrap them...

I guess you are already into it -- unfortunately. You could reactivate an older version of openssl, I guess, but then that would be a mess for everything else that has gone on.

/opt/local/libexec/apple-gcc42/gcc/powerpc-apple-darwin8/4.2.4/ld is a symlink to ../../../../../bin/ld aka /opt/local/bin/ld, so yeah, not a gcc issue. Please confirm that that is the case on your system, and show port provides result on that file, as well as port installed ld64 ld64-97.

[jmroot (Joshua Root)]

So uh, yeah, I thought this sounded familiar somehow. :)

Dupe of #57016.

Replying to jmroot:

Yes, /opt/local/libexec/apple-gcc42/gcc/powerpc-apple-darwin8/4.2.4/ld points to ../../../../../bin/ld, which is /opt/local/bin/ld (same inode) which is a sym-link to `/opt/local/bin/ld-97 `.
