Updating This Repo

To update the Boost version or add a new library, follow these steps:

You will have to use PowerShell if you are on Windows.

1. Download Boost and extract the package.
   You can clone the Boost repo and cd into it:

   git clone https://github.com/boostorg/boost
   cd boost

2. Checkout a specific Boost version and initialize submodules.
   For Boost 1.82.0:

   git checkout boost-1.82.0
   git submodule update --init --recursive

3. Build the bcp tool:

   • Windows:

     .\ootstrap.bat
     .\b2 tools�cp

   • Linux/macOS:

     ./bootstrap.sh
     ./b2 tools/bcp

4. Store the Boost directory in a variable:

   • Windows:

     $boost_dir = $pwd

   • Linux/macOS:

     export boost_dir=$(pwd)

5. Add bcp to your PATH:
   (The correct output path is printed by b2 during the build. The following are just examples—do not include the bcp executable name, only the directory containing it.)

   • Windows:

     $env:Path += ";$boost_dir\bin.v2\tools\bcp\msvc-14.3\release\link-static\threading-multi"

   • Linux/macOS:

     export PATH="$boost_dir/bin.v2/tools/bcp/gcc-15/release/link-static:$PATH"

6. Change to this repository’s directory (typically shadPS4/ext-boost).
   Make sure you stay in the same terminal session so you don’t lose your environment variables.

7. Remove the existing Boost boost and libs directories.
   (Only necessary when upgrading Boost, in case the new version removes any files.)

8. If updating Boost, update the Boost version in this README to keep things consistent.

9. Edit boost_libs.txt to add or remove libraries/headers as needed.

10. Run the build script to create the new trimmed-down Boost distribution:

    • Windows:

      .\build.cmd $boost_dir

    • Linux/macOS:

      ./build.sh $boost_dir

11. You may need to update CMakeLists.txt to adjust include directories.

12. Add/remove all changed files in git and commit your changes.
