Peter, these are the exact errors you see when there is an ABI mismatch between standard libs.

You recently had an issue on your system where many things were rebuilt by gcc. How did that wind up getting resolved?

Replying to kencu:

I uninstalled all packages built with GCC 6 and re-activated the old outdated versions. Then I built py27-cython with GCC 5 and installed it. This allowed port to upgrade or re-install nghttp2 and curl which depends on it. On this basis port could build clang-3.9 and llvm-3.9. Afterwards port could upgrade some 40 packages. Gcc5 is the last outdated package. This is the sequence in which the packages were built:

[kencu (Ken)]

That sounds reasonable enough -- I'll try building gcc5 on my 10.6.8/libcxx system and see how it turns out. It could be that this configuration might cause troubles bootstrapping gcc5...although gcc6 builds fine...

[ballapete (Peter "Pete" Dyballa)]

This morning I rebuilt and reinstalled py27-cython with default Clang 3.9, but the build of GCC 5 fails again at the same spot with libbackend. I was wondering how py27-cython could have been built with an outdated GCC 5. Did I make a mistake and use GCC 6 instead again? The sequence of compile commands I used in GNU Emacs to build the ports shows that I used GCC 5 for the last build though…

[kencu (Ken)]

Hmmm. Looks like gcc5 built through overnight and seems to work OK for me.

$ port -v installed gcc5
The following ports are currently installed:

by default then, clang-3.9 on your system would add -stdlib=libstdc++ for you to link against, which is the wrong stdlib for you, and would generate the errors for the missing symbols that you see. As you know I have modified clang-3.9 on my systems to default to adding -stdlib=libc++ if there is no standard lib set for exactly this reason, so that is most likely why my build succeeds and your build fails.

So -- to get past this particular hiccup on your system (which is 10.6.8 / LibcxxOnOlderSystems), the first thing I would do is to try building gcc5 with the following added to the portfile, to specify the standard lib explicitly:

configure.cxxflags-append  -stdlib=libc++
configure.ldflags-append   -stdlib=libc++

If that fails, then remove those two lines from the portfile again, and try building gcc5 with the older default compiler that is installed:

sudo port -v install gcc5 configure.compiler=gcc-4.2

I know that goes against what we usually do with macports, but it should work in this specific case.

[ballapete (Peter "Pete" Dyballa)]

Replying to kencu:

configure.cxxflags-append  -stdlib=libc++
configure.ldflags-append   -stdlib=libc++

This change failed. Could be I put it onto the wrong lines…

Yes, this did the job!

[ballapete (Peter "Pete" Dyballa)]

There must be more wrong. The build of mediainfo fails similarly.

Could be I need to update the Portfiles from my local repository?

Actually only one difference is left:

diff ~/local/devel/elftoolchain/Portfile /opt/local/var/macports/sources/nue.de.rsync.macports.org/macports/release/tarballs/ports/devel/elftoolchain/Portfile

< platform darwin 10 {
< 	depends_lib-append          port:snowleopardfixes
< 	configure.ldflags-append   -lsnowleopardfixes
< }
< 

Updated Portfiles either have this "patch" included or a

PortGroup           snowleopard_fixes 1.0

statement. So most of my local versions have become obsolete.

Anyway, I am rebuilding/reinstalling clang-3.9, llvm-3.9, cctools, ld64-127.

[ballapete (Peter "Pete" Dyballa)]

The compilers are OK, they can build packages like emacs or unbound. So it's something mediainfo.

[kencu (Ken)]

I can't reproduce this error on my systems. gcc5 builds without issue for me using several different compilers. It just sails right past the specific area where Peter had the issue above. I think it must be something specific to his setup, therefore...
