Building

Steps to build an x86_64 binary on M1 Macs

Before starting, you need to install Homebrew for x86_64.

1. Install Rosetta if you haven't via softwareupdate --install-rosetta
2. Run the Homebrew installation command, but prepend arch --x86_64. The command will be arch --x86_64 bash -c ...
3. Create a ~/.intelbrew file with these contents:

   eval "$(/usr/local/bin/brew shellenv)"
   alias brew='arch --x86_64 /usr/local/bin/brew'
   

4. Include it to update your environment variables by running . ~/.intelbrew
5. Edit Homebrew to fetch packages for Ventura (10.13), since the Qt package for Sonoma (10.14) breaks compatibility with libc++: see this error

vim /usr/local/Homebrew/Library/Homebrew/brew.sh
# Edit the file to comment out the version and hardcode it:
# #HOMEBREW_MACOS_VERSION="$(/usr/bin/sw_vers -productVersion)"
# HOMEBREW_MACOS_VERSION="12.0.0"

# Run this only once after installing Homebrew to install dependencies
make tools

# Build the entire app
export PATH="/usr/local/opt/qt@5/bin:$PATH"
make

# Optionally sign it for distribution
make sign

Dependencies:

• Qt5
• luajit
• zlib
• opengl
• lua-curl (see below)
• Bitstream-Vera and Liberation TTF fonts. Will work without these but most likely look terrible.

Build dependencies:

• meson
• pkg-config
• ninja (optional, can tell meson to generate makefiles if you prefer)

Ensuring old versions of Mac are compatible:

By default, the built lcurl.so links to the local version of cURL. Old versions of cURL on old Macs may be too old to include the relevant functions and run into this error:

Error loading main script: error loading module 'lcurl.safe' from file './lcurl.so':
  dlopen(./lcurl.so, 6): Symbol not found: _curl_easy_option_by_id
    Referenced from: ./lcurl.so (which was built for Mac OS X 13.0)
    Expected in: /usr/lib/libcurl.4.dylib

To try to fix this issue, we include the libcurl.4.dylib in our app using dylibbundler.

We change it in mesonInstaller.sh based on https://stackoverflow.com/a/38709580/319066

• otool -L lcurl.so can be used to debug the paths.
• install_name_tool ... is used to change the paths behind the scenes, but dylibbundler does all the work for us.

Old manual steps to build:

Build Lua-Curl:

You need to build Lua-Curl for luajit.

Edit the Lua-Curl Makefile:

Run make. You should get lcurl.so.

Get the PoBFrontend sources:

git clone https://github.com/philroberts/pobfrontend.git

Build:

meson -Dbuildtype=release pobfrontend build
cd build
ninja

Run the thing:

cd /path/to/PathOfBuilding # <- a pathofbuilding git clone
for f in tree*.zip; do unzip $f;done # <- use the provided tree data because reasons
unzip runtime-win32.zip lua/xml.lua lua/base64.lua lua/sha1.lua
mv lua/*.lua .
rmdir lua
cp /path/to/lcurl.so . # our lcurl.so from earlier
/path/to/build/pobfrontend

You can adjust the font size up or down with a command line argument:

pobfrontend -2

Notes:

I have the following edit in my PathOfBuilding clone, stops it from saving builds even when I tell it not to:

OS X

On mac you need to invoke meson with some extra flags, per the luajit documentation:

LDFLAGS="-pagezero_size 10000 -image_base 100000000" meson pobfrontend build
