Building with --disable-alsa fails because ALSA libraries are still used

[simonvanderveldt]

When building with --disable-alsa the build fails when ALSA isn't installed because it still uses ALSA

./configure --prefix=/usr --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --disable-dependency-tracking --disable-silent-rules --docdir=/usr/share/doc/pure-data-0.50_p2 --htmldir=/usr/share/doc/pure-data-0.50_p2/html --with-sysroot=/ --libdir=/usr/lib64 --disable-portaudio --disable-portmidi --disable-alsa --enable-jack --disable-fftw --disable-oss

This is on 0.50.2, I don't see any relevant changes for 0.51.0 but I can test it on that version as well if required.

i think that's (partly) a "won'tfix".

the problem arises when compiling the the embedded copy of PortAudio (which also depends on ALSA).

so, if you want to build completely without ALSA, you ought to also disable the embedded copy of PortAudio.

i see that you also specify --disable-portaudio to no effect (which is the bug that needs fixing).
in the meantime you might try to also specify --without-local-portaudio

[simonvanderveldt]

Ah, you're right, I wasn't paying attention, it shouldn't be compiling portaudio indeed.
Should I rename the issue?

I'll try --without-local-portaudio. And I assume the bug is that when using --disable-portaudio it shouldn't be using portaudio at all, be it a system library or the sources included with Pd, right?

yes.

Just for confirmation
Including the local disables works

No issues when compiling.

Is portaudio/portmidi still used/is there any reason to use it?

[umlaeute]

PA is mainly used on Mac and Win.
