Description
Latest SVN snapshot
I'm currently not able to compile ScummVM because of linking errors. See linker output below.
It's as if the linking process never sees the base/game.o file. I tried passing the --verbose option to the linker, and part of the output read:
attempt to open base/libbase.a succeeded (base/libbase.a)main.o (base/libbase.a)commandLine.o (base/libbase.a)plugins.o (base/libbase.a)version.o
Note how base/game.o is missing. The manual makes vague references to the linker throwing away unnecessary object files, but I don't know what constitutes an unnecessary object file.
http://www.lysium.de/blog/index.php?/archives/222-Lost-static-objects-in-static-libraries-with-GNU-linker-ld.html has some things to say about the problem, but I don't really understand it yet.
I do know that if I add base/game.o manually to the build command, or surround base/libbase.a with -Wl,--whole-archive ... -Wl,--no-whole-archive it works.
I did notice that the code in base/game.cpp is not in any namespace, but I don't know if that makes any difference.
Linker output:

I think the wrapCompressed...Stream() errors were the ones I got this morning. I believe things were fixed (and then thoughtfully re-broken again :-) at some point during the day.

Though when building a very stripped-down version of ScummVM, that only contained one work-in-progress engine (that someone else is working on, not me), I too got the wrapCompressed...Stream() errors. So apparently they can still happen, under certain circumstances. I haven't tried to reproduce it with the "real" ScummVM however.

I'm also getting some other ones:
