On older OS versions, apple-gcc42 can't find libstdc++

The end of building goes this way:

Replying to jeremyhu@…:

Eh... you don't have a /usr/lib/libstdc++.dylib ... ?

This file exists, but this file belongs on Tiger, Mac OS X 10.4(.11) to GCC 4.0.1. MacPorts' GCC 4.2.1, opt/local/bin/g++-apple-4.2, which was used for compilation of ppl, has its own /opt/local/lib/apple-gcc42/gcc/powerpc-apple-darwin8/4.2.1/libstdc++.dylib. While the old apple-gcc42 @5666.3_7 did provide that file, apple-gcc42 @5666.3_8 seems to remove it.

With apple-gcc42 @5666.3_7 set active I could compile ppl.

Later I can attach logs from activating/deactivating apple-gcc42 and list the files activated/installed with ls. But before I can do that I have to document a bug with GCC 4.7.1 on PPC Tiger…

[ballapete (Peter "Pete" Dyballa)]

A 'diff activate_apple-gcc42\ @5666.3_8 activate_apple-gcc42\ @5666.3_7' form the saved logs of "port -vd activate …" gives (edited):

The following installed ports are outdated:

and "port -v upgrade outdated" tries to install completely different packages!

yes, it removes it on purpose... so the compiler will just use /usr/lib/libstdc++.dylib

I still don't understand how you can have /usr/lib/libstdc++.dylib and have the linker complain "ld: library not found for -lstdc++"

Because the non-default 'CC=/opt/local/bin/gcc-apple-4.2' and 'CXX=/opt/local/bin/g++-apple-4.2' know that they can't use the default ld?

In the evening I can make some tests, for example with compiling GNU Emacs 24.2.50, to see what gets used… with both apple-gcc42 @5666.3_7 and apple-gcc42 @5666.3_8.

[ballapete (Peter "Pete" Dyballa)]

It seems that that the port documentation (man port) is only loosely connected to reality. Both described methods to rebuild ppl, 'port upgrade --force ppl' and 'port -n upgrade ppl' rebuild (or install?) a zillion of packages. Maybe one of these days it will happen that ppl itself gets rebuilt…

They use MacPorts's ld64 linker, but it should be finding /usr/lib/libstdc++.dylib ...

You can just 'sudo port -v -f uninstall ppl && sudo port -v install ppl'

Lipo reports quite the same:

Do I simply need to create a symlink libstdc++.dylib in /usr/lib ?

Ok, so when I asked if you had /usr/lib/libstdc++.dylib in my initial comment, you said yes, but you actually don't have it.

You *should* have it on your system, so yes, please restore your /usr/lib/libstdc++.dylib symlink...

Replying to jeremyhu@…:

Ok, so when I asked if you had /usr/lib/libstdc++.dylib in my initial comment, you said yes, but you actually don't have it.

Since none of the Mac OS X versions I use has a symlink "/usr/lib/libstdc++.dylib" I supposed you meant the regular "/usr/lib/libstdc++.6.dylib" symlink.

You *should* have it on your system, so yes, please restore your /usr/lib/libstdc++.dylib symlink...

With this extra symlink ld64 could be built and ppl is building after configure finished, finding an useful GMP installation.

[jeremyhu (Jeremy Huddleston Sequoia)]

Reopening ... it looks like some ancient versions actually don't have that symlink, so we should set it up in apple-gcc4{0,2} and llvm-gcc42
