Hey @retokromer , thanks for your reply. Actually, I successfully installed it by deleting --with-libflite after I posted this issue. And why did I set --with-openssl@1.1? I'm not sure. I used brew options homebrew-ffmpeg/ffmpeg/ffmpeg --compact to get it. I believe I might have installed another tool that depends on openssl@1.1, so I have multiple versions of OpenSSL in my system.

Thanks again.

[retokromer]

Hello @iiiyu : you need to install Flite before running the FFmpeg formula, as indicated in the ReadMe, then it should work fine.

[iiiyu]

Hello @iiiyu : you need to install Flite before running the FFmpeg formula, as indicated in the ReadMe, then it should work fine.

I've been researching for three hours and I can't find a way to install it.

[retokromer]

If I remember carefully, it’s MacPorts.

[slhck]

I've found a guide here: https://stackoverflow.com/a/61189269/435093 — maybe this works?

Hey @slhck In fact, I have already compiled and installed it. But it doesn't seem to be working.

If I remember carefully, it’s MacPorts.

So, it looks like I have to install MacPorts. To be honest, I don't want to install both Homebrew and MacPorts on my computer at the same time.

[slhck]

I have already compiled and installed it

It would be good if you could already provide more background on what you've tried and where you got stuck, to avoid us having to research things that you already know.

Regarding the specific problem, it looks like you already have the library compiled and installed but ffmpeg is not finding it. Per the error message, can you access ffbuild/config.log and show its contents?

So, it looks like I have to install MacPorts. To be honest, I don't want to install both Homebrew and MacPorts on my computer at the same time.

That makes sense. (I mean, not installing both.)

[retokromer]

As long as I know, there is no Homebrew formula for Flite.

Sure, I am glad to provide this log. Where can I find it? ffbuild/config.log

[retokromer]

I am travelling at the moment. Next weekend I can check what I did, when I added the option. I used it last year with the students (more for fun rather than seriously).

Please enjoy your travelling, I am really thankful for your reply. Actually, I just need fdk-aac at the moment. So, even if my ffmpeg is without libflite, I am good now.

[slhck]

I am afraid I don't know where it is stored exactly; I would expect it to be in the same directory as the last lines from the log: /Users/ewan/Library/Logs/Homebrew/ffmpeg

config.log

I am not good with Clang. Could it be because /usr/local/lib isn’t included in the Clang path when ffmpeg is compiled?

[slhck]

So your Homebrew installation lives in /opt/homebrew (which is where it would typically be under Apple Silicon), and your flite installation is in /usr/local/lib which would be Homebrew's previous location (under x64). Indeed clang can't find the libraries and therefore fails.

Assuming the headers are in /usr/local/include, you should add -I/usr/local/include explicitly to the clang command. Homebrew does not do that on its own, see: https://github.com/orgs/Homebrew/discussions/868

Can you try with:

export CPPFLAGS=-I/usr/local/include"
brew install homebrew-ffmpeg/ffmpeg/ffmpeg  --with-chromaprint --with-decklink --with-fdk-aac --with-libflite --with-game-music-emu --with-harfbuzz --with-jack --with-jpeg-xl --with-libaribb24 --with-libaribcaption --with-libmodplug --with-libopenmpt --with-librist --with-librsvg --with-libsoxr --with-libssh --with-tesseract --with-libvidstab --with-opencore-amr --with-openh264 --with-openjpeg --with-openssl --with-rav1e --with-svt-av1 --with-rtmpdump --with-rubberband --with-two-lame --with-webp --with-xvid --with-zeromq --with-zimg --with-srt --with-libvmaf --with-libxml2 --with-libzvbi --with-aribb24 --with-libbluray --with-libbs2b --with-libcaca --with-libgsm --with-openssl@1.1 --with-speex

I try

export CPPFLAGS=-I/usr/local/include"

It doesn’t work. but you inspired me.

Then I tried this

ln -s /usr/local/lib/libflite* /opt/homebrew/lib/
ln -s /usr/local/include/flite /opt/homebrew/include/flite
brew reinstall homebrew-ffmpeg/ffmpeg/ffmpeg --with-chromaprint --with-decklink --with-fdk-aac --with-libflite --with-game-music-emu --with-harfbuzz --with-jack --with-jpeg-xl --with-libaribb24 --with-libaribcaption --with-libmodplug --with-libopenmpt --with-librist --with-librsvg --with-libsoxr --with-libssh --with-tesseract --with-libvidstab --with-opencore-amr --with-openh264 --with-openjpeg --with-openssl --with-rav1e --with-svt-av1 --with-rtmpdump --with-rubberband --with-two-lame --with-webp --with-xvid --with-zeromq --with-zimg --with-srt --with-libvmaf --with-libxml2 --with-libzvbi --with-aribb24 --with-libbluray --with-libbs2b --with-libcaca --with-libgsm --with-openssl@1.1 --with-speex

and I reinstalled it successfully.

So, I am summarizing how to install FFmpeg on Apple Silicon.

1. Install Flite

git clone https://github.com/festvox/flite.git
cd flite/
./configure
make
sudo make install

2. Make there are links.

ln -s /usr/local/lib/libflite* /opt/homebrew/lib/
ln -s /usr/local/include/flite /opt/homebrew/include/flite

3. Follow Readme

brew install homebrew-ffmpeg/ffmpeg/ffmpeg $(brew options homebrew-ffmpeg/ffmpeg/ffmpeg --compact)

It works for me.

[slhck]

Glad you got it solved. It's certainly not the cleanest solution, and I thought passing the CPPFLAGS would work, but having a symlink in place is surely also works. It's just that if you ever decide to update flite you would need to modify/update the symlinks.

[iiiyu]

Is it possible to update here

homebrew-ffmpeg/Formula/ffmpeg.rb

Lines 207 to 208 in 51676b0

	args << "--extra-cflags=-I#{HOMEBREW_PREFIX}/include"
	args << "--extra-ldflags=-L#{HOMEBREW_PREFIX}/include"

like

--extra-ldflags=-L/first/path -L/second/path -L/opt/homebrew/include

maybe. I am not sure.

[slhck]

No, because we would not want to hardcode other paths into a Formula. What if you wanted to install flite somewhere else? That's where the environment variables would come into play, by passing in the extra include paths to the compiler. I am not sure why they are not working though.

You are right, forget about my dirty solution.

[exekutive]

If I remember carefully, it’s MacPorts.

You have tested this? If so I'd love to know how you run both package managers concurrently on a system without conflict, and how you pursuaded HB to use MP packages (or any non-HB packages) as dependencies because HB is definitely not designed to work that way out of the box.

[retokromer]

You have tested this?

Indeed, my students did it last year. The path issue has already been discussed earlier in this thread. This was just meant as a quick and dirty solution. Yet if this year they are still interested in experimenting text to speech synthesis, then they should compile Flite manually. Note that writing the corresponding Homebrew formula would non be difficult.

[exekutive]

I don't think so. Maybe when your students tried, there was a hombrew core formula for flite.
As things are now, the option cannot work as advertised, and certainly not without modification.

the --with-libflite option should be removed from the formula

[retokromer]

Maybe when your students tried, there was a hombrew core formula for flite.

No, there wasn’t.

the --with-libflite option should be removed from the formula

Why? It was included as option to FFmpeg twelve years ago. I added it here after my last year’s course and I am not going to remove it. You are completely free not to use it.

[exekutive]

Because HB does not support non-HB dependencies, thus this is a broken formula.
And because issues like this one exist, and you will get more, since this repository is being suggested all over the internet as solution to the complaints about HB removing options. ffmpeg is a very popular tool. The issue was discussed but not really resolved.
Removing it is simply the right thing to do.

[slhck]

There is a solution that involves creating a symlink.

I will check if it's possible to link against non-Homebrew libraries that are installed locally. The flag I suggested does not seem to be the right one.

So the option works, but requires some manual changes. In any case the user has to compile the dependency manually. I am against removing the option.

[retokromer]

Removing it is simply the right thing to do.

No, not at all: it’s part of the official FFmpeg, and we wish to include the option in our Homebrew formula as well. As said, our formula works in different ways, one of them was described in detail above.

Why do you not write a Homebrew formula for Flite? Here in this repository that is out of scope.

[exekutive]

I will check if it's possible to link against non-Homebrew libraries

It's not supported, but sure, check. The rest of us understand that you cannot maintain a functioning, up-to-date, dependency hierarchy when you start mixing in unmanaged packages.

There is a solution that involves creating a symlink.

monkeying with homebrew and breaking the mechanics is a hack. Not a solution

[exekutive]

Why do you not write a Homebrew formula for Flite?

I am not a maintainer for flite or homebrew core

[slhck]

Why do you not write a Homebrew formula for Flite?

I am not a maintainer for flite or homebrew core

You have to be neither to do that. Anyone can provide a formula.

[slhck]

monkeying with homebrew and breaking the mechanics is a hack. Not a solution

As said, there is a solution that I'm well aware of is not a reliable one. Please take this kind of demeaning and snarky attitude somewhere else. You're free to not use this option if it doesn't work for you.

[retokromer]

You're free to not use this option if it doesn't work for you.

Indeed, I already said it above.
