appstream-glib fails with Undefined symbols for architecture x86_64 10.5

[rmottola (Riccardo)]

This happens on 10.5 x86-64.

Build with gcc-7 on Leopard. clang-7.0 & clang-3.7 have the same issue.

apple gcc 4.2 is not enough to compile.

@kencu do you have some clue here?

[kencu (Ken)]

is libstemmer in the link somewhere?

[rmottola (Riccardo)]

Replying to myself... before deciding if apple gcc 4.2 needs to be blackisted, the error is this:

doesn't look at a compiler limitation, at a first glance.

@kencu yes, I see -lstemmer on the command line when building with gcc7

clang-7.0 fails the same as gcc7 with stemmer symbols.

[kencu (Ken)]

do you have another libstemmer hiding somewhere (/usr/lib?).

Perhaps go into the right folder, and manually run the link, but add -Wl,-v to the flags to force the linker to be verbose.

[rmottola (Riccardo)]

I upgraded in the meanwhile most of packages here on 10.5 and retry, with standard gcc 4.2

With this I think it is related to: ​https://trac.macports.org/ticket/66257

[rmottola (Riccardo)]

building with macports-gcc-7 now works for me now...

Great, glad this issue is resolved!
