Building on Mac Fails #3

classicjazz · 2019-08-09T22:00:02Z

Manual building on Mac fails at the $ cmake .. command.

So based on the errors above, I ran "homebrew install libtag". And this resulted in Pouring taglib-1.11.1.mojave.bottle.tar.gz.

Running cmake again:

cmake ..
-- Checking for module 'taglib'
-- Found taglib, version 1.11.1
-- Configuring done
-- Generating done
-- Build files have been written to: /Users/mike/loudgain/build

But then running make results in the following error:

make

/Users/mike/loudgain/src/loudgain.c:70:10: fatal error: 'ebur128.h' file not found

Thanks for your continuous feedback, appreciate it, since I don’t have access to a Mac and there seem no VMs about. :-(

Good work on "taglib"!

You also need the development headers for libebur128, maybe this library can be installed with homebrew, too? There is a formula in homebrew-core.

Hint: I saw in the formula that it has a dependency on "speex". If homebrew does not resolve that, you might also have to install speex before you can brew libebur128.

Taglib 1.11.1 and libebur128 1.2.4 are good versions to work with.

I much hope you get it going and we can somehow pusblish an easy "recipe" for Mac—would be a great relief for other Mac users, too!

Moonbase59 · 2019-08-10T09:04:52Z

If homebrew can resolve dependencies automatically, you could probably simply add something like this in your loudgain formula:

  depends_on "cmake" => :build
  depends_on "pkg-config" => :build
  depends_on "libtag" => :build
  depends_on "libebur128" => :build

Another question: Does homebrew always include the development headers when installing something and do you by chance have ffmpeg installed?

That’s because I tried to keep loudgain as versatile as possible while having as few dependencies as possibe (really only cmake, pkg-config for building, and libtag, libebur128 and some of the FFmpeg libraries for running).

Moonbase59 · 2019-08-10T09:57:46Z

Just talked to a very helpful person on the #machomebrew IRC channel. He tells me the following:

homebrew will auto-install dependencies when they are in the formula.
homebrew will also apparently install the program's development header (.h) files when installing something.

This could mean if you add

  depends_on "cmake" => :build
  depends_on "pkg-config" => :build
  depends_on "ffmpeg"
  depends_on "libtag"
  depends_on "libebur128"

in your loudgain formula, we should get all the header files needed for compilation and all libraries needed to run loudgain.

For best results (i.e., least upstream bugs) …

FFmpeg version should be >= 3.4.6 (loudgain -v should show at least libswresample 2.9.100)
libtag (or libtag1) should be >= 1.11.1, best compiled from GitHub because some bugs have been fixed but no new version came out since
libebur128 should be >= 1.2.4 because of a bug in older versions

Let me know if this works out.

Moonbase59 · 2019-08-10T12:43:02Z

You also probably found a bug, congratulations! :-)

classicjazz · 2019-08-10T14:01:25Z

Yes, I am running MPV head and FFMPEG head. I can uninstall if needed for testing.

Manually installing via brew the following, shows:

libebur128 1.2.4 is already installed and up-to-date
taglib 1.11.1 is already installed and up-to-date

I am getting closer but still errors...

Moonbase59 · 2019-08-10T14:33:34Z

Hmm. Looks like it tries to "cmake ." instead of "mkdir build && cd build" → "cmake .." like in manual compilation. Wonder how that can be fixed.

Is there something like a "pre-build" step in homebrew formulae that could be used to create the build dir and change into it?

Maybe more like:

def install
  mkdir "build" do
    system "cmake", "-G", "Unix Makefiles", "..", *std_cmake_args
    system "make"
    system "make", "install"
  end
end

Moonbase59 · 2019-08-10T18:12:18Z

Coming back to "manual install": Now that libebur128, taglib and a recent FFmpeg are installed, you might again try the original build instructions at

Please try commit 97cbaab. I try to use <util.h> instead which should have the needed stuff on Mac OS X.

Trying MacOS turns out to be a Pandora’s Box … thanks for testing!
You might want to test f8e2a7e in the meantime while I’m looking up how MacOS handles all these ioctl() things …

a92aefb removes the obsolete util.h. I'm still fighting with conditional #includes (either include pty.h on Linux or util.h on MacOS), any idea?

Moonbase59 · 2019-08-10T21:51:35Z

Wasn’t so obsolete, might want to try 259a920 …
I neglected erasing the build folder between tries, please be sure you do so we start on a clean slate.

Moonbase59 · 2019-08-12T13:39:22Z

Any news? I’d much like to get a working and homebrew-installable MacOS version 0.5.4 out ;-)

classicjazz · 2019-08-12T14:27:43Z

For the manual build, it also errors out:

Moonbase59 · 2019-08-12T23:18:45Z

Seems like clang (?) doesn’t find the FFmpeg libraries in /usr/local/…. I’m sure they are there but maybe something Mac-specific is missing in CMakeLists.txt.

I had access to a 10.14.04 Mojave iMac today, for a few minutes, and interestingly enough, got it compiled and working using Homebrew, by using

brew install --HEAD libtag
brew install --HEAD Moonbase59/tap/loudgain

I wonder what brew does differently. Have you got any ideas (and are you actually a programmer)?

The formula used is here.

Moonbase59 · 2019-08-13T01:10:34Z

I‘ll release a version 0.5.4 tomorrow that‘ll build with Homebrew, but I suggest investigating further in a workable manual build and leave this issue open for the time being.

Moonbase59 · 2019-08-13T05:00:12Z

MacOS 10.14+ broke linking by using -isysroot which excludes /usr/local/lib. Fixed that in 0.5.4 in CMakeLists.txt. Manual compilation now works here (tested with Mojave 10.14.4).

/usr/local is the prefix used by homebrew, but the other popular packager on macOS is MacPorts, which uses /opt/local. Can this directory be added as well?
