I don't believe anyone ever tried to build libcxx with clang-3.3. I would not expect that to be successful. That is most likely your problem here. I would just go with the defaults, as they seem to work.

If you're following LibcxxOnOlderSystems and running into trouble, please post a ticket with exactly where things went wrong. Some compilers have been deleted, and I might need to tweak those instructions again.

During bootstrapping 10.6.8 with LibcxxOnOlderSystems, you build clang-3.4 with the system tools, and then use that clang-3.4 to build an initial version of libcxx. Then you build clang-3.4 again against libc++ using the first version of clang-3.4, then build clang-3.7 with the new version of clang-3.4, then build clang-5.0 with clang-3.7.

And then, you build libcxx again with clang-5.0 to get the fully thread_local supporting libc++ OS we have all come to love. Once you are there, you can build clang-8.0 (and newer, if we remain interested)!

Hello ,

i just tried to follow a guid to get a program (Blackmagic Disk v.2.1) functioning on SL.

it suggested installing MacPorts and running

sudo port selfupdate sudo port install clang-3.3 -analyzer -python27 sudo port install libcxx +universal configure.compiler=macports-clang-3.3

The first two commands succeeded, the last one failed.

Hope i did not a foolish thing;

If i can, i will try to follow your suggestion instead

Oh, I see. Must be a very old guide.

Then if you just install libcxx you should be good

sudo port -v install libcxx

thanks, it results in the following

Error: Failed to deactivate libcxx: Active version of libcxx is not 5.0.1_4+emulated_tls+universal but 5.0.1_4+universal.

Warning: Failed to execute portfile from registry for libcxx @5.0.1_4+universal
--->  Deactivating libcxx @5.0.1_4+universal
--->  Activating libcxx @5.0.1_4+emulated_tls+universal

[mrkapqa]

Now it is active

The following ports are currently installed:
  libcxx @5.0.1_4+emulated_tls+universal (active)
  libcxx @5.0.1_4+universal

Hope this is acceptable, the program would not start nontheless;

Please close this bug,

Thank you very much.

You have the right libcxx installed. Must be some other issue with that software now.
