Circular dependencies involving clang-3.7, xz, etc

[tehcog (tehcog)]

I am trying to build a bootstrap version of macports 2.9 from which I can then reference curl in my normal macports 2.9 install.

I am using the following method:

---

1) cd ~/temp/macports_curl

2) git clone -b release-2.9 ​https://github.com/macports/macports-base.git

3) cd macports-base

4) ./configure --prefix=/opt/bootstrap_29 --with-applications-dir=/opt/bootstrap_29/Applications --without-startupitems

5) make && sudo make install

6) sudo /opt/bootstrap_29/bin/port -v sync

---

This is where I have an issue:

7) sudo /opt/bootstrap_29/bin/port -v -N install curl

This operation seems to culminate in the following error (please see attached log file):

Error: The following dependencies were not installed because all of them have unmet dependencies (likely due to a dependency cycle): xz libidn2 libpsl zlib zstd openssl curl-ca-bundle gettext clang-3.7 gettext-tools-libs cctools libxml2 llvm-3.7 ld64 perl5 ld64-274 perl5.34 gdbm libunistring autoconf automake m4 python310 sqlite3 openssl3
Error: Follow https://guide.macports.org/#project.tickets if you believe there is a bug.
Error: Processing of port curl failed

Any suggestions for how to accomplish this (works in 2.8.1)? Thank You.

Looks like legitimate circular dependencies. (Removed: rdeps listings from a different OS)

Wait, you're on Ventura? What is depending on clang-3.7?

[ryandesign (Ryan Carsten Schmidt)]

According to the log, not macOS 13 but Darwin 13, aka OS X 10.9.

[jmroot (Joshua Root)]

Ah right, that makes more sense. So on 10.9 the problem is pretty clear: gettext depends on clang-3.7, which depends on xz, which depends on gettext.

It looks like [8fbc7254defcd069e114ca06e38571da70474bac/macports-ports]/[3caa3b4ab9f335dfff75ec10ba75a435bc32bd28/macports-ports] are probably the cause. Perhaps the easiest fix would be for llmv-3.7 to use xz-bootstrap on the affected OS versions (or just always use it?)

Replying to jmroot:

It looks like [8fbc7254defcd069e114ca06e38571da70474bac/macports-ports]/[3caa3b4ab9f335dfff75ec10ba75a435bc32bd28/macports-ports] are probably the cause.

I forgot about those. Since upstream has dragged their feet on fixing it, I'd like to add a patch to gettext to fix it so that we don't have to blacklist clang 6xx anymore. The fix should be: everywhere there is a check whether to use __has_attribute, change it from 6000000 <= __apple_build_version__ to 7000000 <= __apple_build_version__. I should verify that on Mavericks before committing it.

Yes that works and I will include the fix in ​https://github.com/macports/macports-ports/pull/21649 before merging it.

gettext: Don't blacklist clang 6xx; fix it instead
