Discussion:
Getting stuck building on Linux

Ubuntu 14.04.

I use default

./configure CXXFLAGS="-std=gnu++11"

Even on a fresh checkout, running make I get stuck on the following

audacity-AudioIO.o: In function `AudioIO::MidiTime()':
/home/gale/audacityHEAD/audacity/src/AudioIO.cpp:3984: undefined
reference to `PaUtil_GetTime'
collect2: error: ld returned 1 exit status
make[2]: *** [audacity] Error 1
make[2]: Leaving directory `/home/gale/audacityHEAD/audacity/src'
make[1]: *** [all] Error 2
make[1]: Leaving directory `/home/gale/audacityHEAD/audacity/src'
make: *** [all-recursive] Error 1

Can anyone give some pointers how to get round this?

Thank you.

I think I see the problem, see commit
38fd97b8e26060332ab3e9e000a8882326a70ba7

This touches lib-src. Can we put this small change upstream? Roger?

I think the problem is that you can compile portaudio either as C or as
C++, and if as C, then your build is fine, but if as C++, then the missing
function was not given "C" linkage agreeing with the header file.

Or the other way to fix it is to make sure the makefiles always compile
with C not C++.

I've seen this before, and it's an odd one. It happens on some machines
but not others.
Midi synchronization uses PaUtil_GetTime, which isn't part of portaudio's
public API but instead is one of the methods declared in pa_util.h
<http://portaudio.com/docs/v19-doxydocs-dev/pa__util_8h.html>. On some
machines, this is still fine, but on others it doesn't link. I'm not sure
why. In both cases, the method seems to be present in the binary: My pi
has it as "000000c0 T PaUtil_GetTime" in pa_unix_util.o and my main
computer, via windows subsystem for Linux, has it as "00000000000000f0 T
PaUtil_GetTime" also in pa_unix_util.o. So I don't get why it links on my
computer but not my pi, and it's not something that I can easily test
because compiling on my pi takes a very long time.

What I did may be the minimal fix for the Audacity build, but the correct
fix for portaudio upstream might enlarge the extern "C" block to include
other functions declared "C" but not used by Audacity.

That fixes building on my pi. Though, if the system version of portaudio is
used, it probably won't make a difference; probably the m4 checklib file for
portaudio needs to be changed to check if the system version is usable,
which I can try to do. In the mean time, using ./configure
CXXFLAGS="-std=gnu++11" --with-portaudio=local should work.
Yes that enables me to link. Thank you.

Having imported a MIDI track I can't play it with the play button (OK
I have not
researched this yet). But no further audio generation or playback/recording
is then possible, as if MIDI playback were still running.

This seems poor, if it is supposed to be like this on Linux.

Hm, no; that's not normal. If you don't have any MIDI devices set up, it
should give you a notification of that and cancel playback; you shouldn't
get stuck with playback disabled.

Gale does not have all of your work if he builds audacity/master

And that is my fault, for not catching up yet in review and pushing of your
stuff.

Please needle me to do that.
