How to build and install on macOS? #37

dosentmatter · 2020-12-11T05:52:30Z

I am on macOS Mojave 10.14.6.

I looked at macOS install instructions in INSTALL. I can't get past the ./configure or make steps. Do you have any suggestions? I'm not sure what version of gcc is required. I'm interested in trying out the toisanese TTS.

Setup:

$ cd ekho-8.3
$ brew install pulseaudio gcc5

$ # I built and installed espeak-ng by following instructions here
$ # https://github.com/espeak-ng/espeak-ng/blob/master/docs/building.md#linux-mac-bsd
$ cd espeak-ng
$ glibtoolize -c
$ ./autogen.sh
$ ./configure --prefix=/usr/local
$ make
$ make install

Configure:
I tried the following without success.

$ cd ekho-8.3

I wasn't able to figure out how to build on macOS, but I instead found a way to build it in a debian docker image and play the audio using pulseaudio over the local network to my mac host.

@hgneng, would you like me to create a PR with the Dockerfile and instructions? We could also publish the image on dockerhub for an easy cross-platform install.

hgneng · 2020-12-14T03:06:07Z

I have never built Ekho on Mac. Ekho use pulseaudio to run but pulseaudio is not running on Mac.

I am not familiar with PR or Docker. If you think others will benefit from your work, go ahead. I will put your work on Ekho's page. Thank you!

dosentmatter · 2020-12-20T02:23:14Z

I tried building on macOS with libpulseaudio and libsndfile installed but I kept getting errors, so I gave up.

PR means Pull Request. I have a Pull Request coming soon to be able to run ekho on macOS and Windows through a docker container.

Docker is software that allows running containers through OS-level virtualization. You can think of a container as a lightweight VM.

I got ekho running on a Docker container on different OS's using the following methods:

Linux:

Add the host's /dev/snd device to the container.
Run ekho inside the container. This plays audio on the host through the dev/snd device.

Although ekho can be built and run on Linux, the benefit of using Docker is to skip having to build ekho yourself.

macOS or Windows (PowerShell/WSL):

Run pulseaudio server on the host.
In the container, set PULSE_SERVER env variable to point to the pulseaudio server
Run ekho inside the container. This plays audio on the host through pulseaudio network audio.

I have fixed build issues on MacOS. Please try following version:
https://sourceforge.net/projects/e-guidedog/files/Ekho/8.5/

Thank you for opening this issue. I have never thought that Ekho can port to MacOS easily.

You need to launch pulseaudio deamon first. In my environment, pulseaudio installed from HomeBrew is not able to launch. But I can run it by pulseaudio. However, pulseaudio runs very unstable.

At least, you can out wave to a file with ./ekho "some text" -o demo.wav and play it with play demo.wav

dosentmatter · 2020-12-22T20:17:00Z

Hey @hgneng, thanks for the fix. I got it built and installed with macOS-provided clang and also homebrew-provided clang, although with a lot of warnings.

You can start pulseaudio daemon with brew services start pulseaudio. If you are having issues, try restarting it with brew services restart pulseaudio.

I wasn't able to get gcc-10 to work though. For some reason, /usr/local/include isn't part of my gcc-10 include path and /usr/local/lib isn't part of my libs, so I tried ./configure CC=gcc-10 LDFLAGS=-L/usr/local/lib CPPFLAGS='-I/usr/local/include' CXX=g++-10, without success. It still says ld: symbol(s) not found for architecture x86_64. Oh well, it's not a big deal since clang works.

So here are my steps to get it working:

$ brew install pulseaudio libsndfile
$ brew install llvm # optional if you want to build with homebrew clang

$ # Have to install libespeak-ng manually because it's not provided by homebrew.
$ # I built and installed espeak-ng by following instructions here
$ # https://github.com/espeak-ng/espeak-ng/blob/master/docs/building.md#linux-mac-bsd
$ cd espeak-ng
$ brew install libtool
$ # need to do this because `m4` has symlinks to /usr/share/aclocal
$ # whereas mac has it at /usr/local/share/aclocal, probably due to homebrew.
$ glibtoolize -c
$ ./autogen.sh
$ ./configure # default installed at /usr/local with --prefix=/usr/local
$ make
$ make install
$ espeak-ng # test this command to make sure no errors.

$ cd ekho-8.5
$ ./configure # this uses macOS clang

$ # alternatively use homebrew clang
$ ./configure CC=/usr/local/opt/llvm/bin/clang LDFLAGS=-L/usr/local/lib CPPFLAGS=-I/usr/local/include'CXX=/usr/local/opt/llvm/bin/clang++

$ make
$ make install
$ brew services restart pulseaudio # this ensures pulseaudio daemon is started
$ ekho 123 # should work now

hgneng · 2020-12-23T03:25:10Z

Thank you for the detail procedures.

I have trouble with start pulseaudio service in brew. I think it's an issue of my Homebrew environment.

$ brew services start pulseaudio
Error: undefined method `named' for #<OptionParser:0x00007f9b3aaa0cd0>
/usr/local/Homebrew/Library/Taps/homebrew/homebrew-services/lib/services_cli.rb:75:in `run!'
/usr/local/Homebrew/Library/Taps/homebrew/homebrew-services/cmd/services.rb:48:in `services'
/usr/local/Homebrew/Library/Homebrew/brew.rb:110:in `<main>'

dosentmatter · 2020-12-23T04:25:42Z

No problem.

Hmm, those errors are within the homebrew ruby code. I wonder how that happened. I found these issues:
Homebrew/homebrew-services#251
Homebrew/homebrew-bundle#751

They say to update or reinstall homebrew.

dosentmatter · 2020-12-23T05:44:29Z

@hgneng, you mentioned that your pulseaudio is runs unstably even when you run it manually.

Here is the homebrew plist. plists are daemon configuration files for macOS launchd service.

Here it is evaluated on my mac:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  <key>Label</key>
  <string>homebrew.mxcl.pulseaudio</string>
  <key>ProgramArguments</key>
  <array>
    <string>/usr/local/opt/pulseaudio/bin/pulseaudio</string>
    <string>--exit-idle-time=-1</string>
    <string>--verbose</string>
  </array>
  <key>RunAtLoad</key>
  <true/>
  <key>KeepAlive</key>
  <true/>
  <key>StandardErrorPath</key>
  <string>/usr/local/var/log/pulseaudio.log</string>
  <key>StandardOutPath</key>
  <string>/usr/local/var/log/pulseaudio.log</string>
</dict>
</plist>

Notice the --exit-idle-time=-1 flag. If you don't set that, it defaults to 20. The default is shown and commented out in /usr/local/Cellar/pulseaudio/*/etc/pulse/daemon.conf as ; exit-idle-time = 20. If you leave it as default, pulseaudio will exit after 20 seconds of inactivity. From my experience, it seems to exit only after you play audio for one last time, ie. it exits when you play audio after 20+ seconds of inactivity.

Perhaps pulseaudio --exit-idle-time=-1 will help with your instability, if you aren't able to fix your homebrew services.

hgneng · 2020-12-24T03:21:34Z

Thank you! After running brew update, pulseaudio service runs normally.

Running brew update needs courage and lucky in China. Usually, it fails at a network issue after waiting for half an hour.

dosentmatter · 2020-12-24T05:26:22Z

You're welcome! That's good that you got it working.

I guess we can close this issue now that we have ekho working for macOS?

dosentmatter · 2020-12-24T22:36:17Z

@hgneng, I saw your blog post about building espeak-ng on macOS.

I saw you mentioned there was no sound for the espeak-ng CLI.

You typed:

espeak-ng 'hello' # no sound

espeak-ng 'hello' -w demo.wav && play demo.wav # works

There are actually a few ways to fix that instead of outputting to a .wav file.

First things first, play isn't included in macOS by default, you have to brew install sox

Option 1 play from stdin:

brew install sox
espeak-ng hello | play -

If you want sound from espeak-ng directly, you need to install pcaudiolib.
See:
https://github.com/espeak-ng/espeak-ng/blob/master/docs/guide.md#problems-with-pcaudiolib
https://github.com/espeak-ng/espeak-ng/blob/master/docs/building.md#linux-mac-bsd

pcaudiolib also isn't provided by brew so need to be built and installed manually. The guides list a bunch of other optional dependencies you can install such as sonic to speed up audio. If you install sonic, make sure to install from the source and not the espeak-ng fork, because it is out of date.

The espeak-ng ./configure command will tell you if you have dependencies installed correctly.

Option 2 Here is a quick guide for a fuller espeak-ng install on macOS:

# https://github.com/espeak-ng/pcaudiolib#mac-os
cd pcaudiolib
./autogen.sh
./configure
make
make install

# Use https://github.com/waywardgeek/sonic instead of out-of-date https://github.com/espeak-ng/sonic
cd sonic
brew install fftw
make
make install PREFIX=/usr/local

cd espeak-ng
glibtoolize -c
./configure --with-extdict-zh --with-extdict-zhy
make
make install

# test audio:
espeak-ng -vyue '冚挷攔'

@dosentmatter, Thank you for the details about espeak-ng. The original link of sonic and config command for extra dictionary is valuable to me.
