Or, build it yourself

These are instructions for the fish shell. Some commands (e.g. export, set) might be different if you're using bash or zsh instead (e.g. CPPFLAGS= instead of set CPPFLAGS)

1. Clone the repo

git clone https://github.com/rcombs/Aegisub
cd Aegisub/
git checkout rcombs-local

2. Install dependencies & setup

brew install autoconf automake ffmpeg ffms2 fftw freetype fribidi gettext icu4c libass m4 pkg-config boost
brew install luajit --HEAD
brew link --force gettext
export LDFLAGS="-L/opt/homebrew/opt/icu4c/lib"
export CPPFLAGS="-I/opt/homebrew/opt/icu4c/include"
export PKG_CONFIG_PATH="/opt/homebrew/opt/icu4c/lib/pkgconfig"
./autogen.sh

3. Build wxWidgets

cd vendor/wxWidgets/
set CPPFLAGS "$CPPFLAGS -D__ASSERT_MACROS_DEFINE_VERSIONS_WITHOUT_UNDERSCORES=0 -I/opt/homebrew/opt/boost/include"
git submodule update --init
./configure --disable-all-features --enable-unicode --enable-utf8 --enable-stl --enable-exceptions --enable-log --enable-threads --enable-palette --enable-baseevtloop --enable-selectloop --enable-gui --enable-timer --enable-menus --enable-intl --enable-xlocale --enable-statusbar --enable-sysoptions --enable-button --enable-bmpbutton --enable-listbook --enable-listbox --enable-listctrl --enable-checkbox --enable-textctrl --enable-hyperlink --enable-treebook --enable-image --enable-stopwatch --enable-scrollbar --enable-longlong --enable-geometry --enable-imaglist --enable-stc --enable-hotkey --enable-regkey --enable-graphics_ctx --enable-dataobj --enable-file --enable-ffile --enable-streams --enable-dragimage --enable-dnd --enable-radiobox --enable-radiobtn --enable-spinbtn --enable-spinctrl --enable-slider --enable-searchctrl --enable-stattext --enable-statline --enable-statbox --enable-statbmp --enable-toolbar --enable-tbarnative --enable-clipboard --enable-menubar --enable-msgdlg --enable-filedlg --enable-fontdlg --enable-textdlg --enable-choicedlg --enable-coldlg --enable-dirdlg --enable-numberdlg --enable-aboutdlg --enable-dataviewctrl --enable-datepick --enable-dirpicker --enable-filectrl --enable-filepicker --enable-fontpicker --enable-treectrl --enable-comboctrl --enable-rearrangectrl --enable-treelist --enable-timepick --enable-accel --enable-headerctrl --enable-variant --enable-datetime --enable-checklst --enable-choice --enable-choicebook --enable-combobox --enable-gauge --enable-tooltips --enable-validators --enable-std_string --enable-std-containers --enable-popupwin --enable-controls --enable-stc --enable-calendar --enable-sash --enable-splitter --enable-arcstream --enable-zipstream --enable-xpm --enable-dynlib --enable-dynamicloader --enable-fontenum --with-zlib --with-expat --with-libpng --with-cocoa --with-macosx-version-min=no --with-opengl --without-libjpeg --without-libtiff --without-regex
make -j10

4. Configure Aegisub

cd ../../
autoreconf -ivf
autoupdate
./configure --with-wxdir="$PWD/vendor/wxWidgets" --with-boost-libdir="/opt/homebrew/opt/boost/lib"

4. Janky fix for error

Edit libaegisub/common/charset.cpp Change #include <uchardet/uchardet.h> to #include <uchardet.h>

5. Build Aegisub

make
make osx-bundle
cd Aegisub.app/Contents/MacOS/
ln -s libicudata.69.1.dylib libicudata.69.dylib
ln -s libbrotlicommon.1.0.9.dylib libbrotlicommon.1.dylib
ln -s libicuuc.69.1.dylib libicuuc.69.dylib
cp /opt/homebrew/opt/boost/lib/libboost_system-mt.dylib libboost_system-mt.dylib
cd ../../../
codesign --force --deep --sign - Aegisub.app

This mostly worked for me, thanks. A few notes:

• I had to further add -I/opt/homebrew/opt/portaudio/include to CPPFLAGS otherwise it fails during the Aegisub build
• I changed --with-boost-libdir="/opt/homebrew/opt/boost/lib" to --with-boost="/opt/homebrew/opt/boost" or it wouldn't work, it seems this has also been changed in the readme in rcombs' fork.
• If you copy the aegisub binary from the src folder to the .app as you showed, it will depend on libraries built in the build folder (there are absolute paths to them in the executable). You can actually fix the .app manually like this for the moment (instead of the rm/cp steps):

cd Aegisub.app/Contents/MacOS
ln -s libicudata.69.1.dylib libicudata.69.dylib
ln -s libbrotlicommon.1.0.9.dylib libbrotlicommon.1.dylib
ln -s libicuuc.69.1.dylib libicuuc.69.dylib

I now have a working .app which doesn't depend on my build folder anymore, and probably works on any M1 machine, at least running Monterey (I think brew libraries are tied to the running OS). I uploaded it here https://transfer.sh/qinOf2/Aegisub.app.7z if anyone needs it

@AuroraWright Thanks a lot! I'll look into modifying the instructions per your notes when I next need to build it myself – I'm guessing there's just some system-to-system idiosyncrasies/differences with this all too.

Very helpful to note about the symlinks, that's definitely a better way of doing it (and confirmed, your linked build works on my machine)! I also had to do a ln -s libboost_system.dylib libboost_system-mt.dylib to get it to work for me when performing these steps myself.

@frozenpandaman I'm glad it worked! About the libboost_system it's not in my command line history and the -mt dylib seems to be different from the other one so maybe I copied it from the brew folder to the .app with Finder and forgot, I did all of this earlier today and was going off my zsh history so it's possible haha.
So maybe this could be added cp /opt/homebrew/opt/boost/lib/libboost_system-mt.dylib libboost_system-mt.dylib

@AuroraWright Ah, that's where the file is (makes sense). Thanks! I updated the instructions in the gist. And then if people don't want to go through all that themselves, they can just download the pre-built binary you posted. I'll mirror it to my site (since transfer.sh seems to only host files for 14 days) and link it above too.

FYI: wangqr/Aegisub#117 (comment)

cc @AuroraWright in case you're interested. I wonder what changed to make these builds work on macOS 12.3.
