fails to build in mixed mode

[falkTX]

I fixed it manually in the mean time, but the build still fails later on.
It was a bit hacky, has I just wanted to get jack2 to build.
My changes - http://kxstudio.sourceforge.net/Paste/repo/LAUJb

so now it fails with:
[177/306] cxxprogram: build/common/Jackdmp.cpp.1.o build/dbus/reserve.c.1.o build/dbus/audio_reserve.c.1.o -> build/linux/jackd

It seems that you'e compiling with old shared memory model, and it seems the code was not updated recently. I guess jack_attach_shm_read has to be defined as a copy of jack_attach_shm with SHM_RDONLY like:

int
jack_attach_shm_read (jack_shm_info_t* si)
{
if ((si->ptr.attached_at = shmat (jack_shm_registry[si->index].id, 0, SHM_RDONLY)) < 0) {
jack_error ("Cannot attach shm segment (%s)",
strerror (errno));
jack_release_shm_info (si->index);
return -1;
}
return 0;
}

thanks, I've got jack2 to build now.
but it doesn't want to start;

Why are you using old System V shared memory model (and not POSIX one) ?

Don't ask me, I'm just trying to build and use jack2.
Previous versions (1.9.8) worked just fine.
Is there a special dependency or ./waf configure flag I need for this?

[falkTX]

in case you need specs, this is Ubuntu 12.04 64bit (~6 month old distro).
GCC at v4.6

[sletz]

The normal ./waf is supposed to using the POSIX shared memory model.

1. Can you log what ./waf configure says?

2. Hopefully someone of the jack-dev list can help
