#23 Attempt to fix the build on higher GCC versions (4.6+)

[Alexey Dokuchaev]

GCC 4.6+ forbids explicit template specialization to have storage class. Specializations of templates cannot explicitly specify a storage class, and have the same storage as the primary template. This is a change from previous behavior, based on the feedback and commentary as part of the ISO C++ Core Defect Report 605. (http://gcc.gnu.org/gcc-4.3/porting_to.html)

Quick sed(1) expression to fix:

sed -E 's,(template<> )(inline )?static ,\1\2,' \
    src/misc/CNestedDataFile/anytype.h \
    src/misc/endian_util.h \
    src/backend/CGraphParamValueNode.h \
    src/backend/CPluginMapping.h \
    src/backend/ALFO.h \
    src/backend/CSound_defs.h

Unfortunately, ReZound would then compile, but fail to link...

These issues have previously been fixed in svn trunk/

Have you tried trunk? Please close this ticket if you find the problems already fixed.

Unfortunately, ReZound (version 0.13.1beta) still does not build (fails to link) with GCC 4.7:

gcc-5 works for me. Though I haven't tested building 32bit. Still a problem on HEAD of trunk?

[Alexey Dokuchaev]

I didnt' try the trunk, but with the latest patches 0.13.1beta builds fine with GCC 4.9 on FreeBSD (64-bit). It does not link though due to incompatible ABIs of std::string between GNU's libstd++ and FreeBSD's libc++, but that is unrelated (and expected).

There are couple of remaining issues with 32-bit builds, but I guess we can take care of them separately. Since as you've said you've committed those patches, I believe this bug can be closed now.

[Davy Durham]

Thanks. Open any other issues as needed.
