Scripts for building SDL 2 libraries for Windows (MinGW, MSVC) and macOS.

build-sdl-libs.sh

#!/bin/bash
# Run in SDL 2 source directory on Linux.
# Built libraries will be copied to ./ztm-libs/{win32,win64,macos-ub1,macos-ub2}
#
# Set up:
# 1. Windows libaries:
# Install mingw-w64 for i686 and x86_64
#
# 2. macOS libraries:
# Follow osxcross directions to set up macOS (11.3) SDK to build a Universal 2 (arm64/x86_64) dylib.
# (I rename osxcross/target/ to osxcross/target-11.3/ but you could change OSXCROSS_TARGET_UB2 below instead.)
#
# Download rcodesign to ad-hoc sign macOS libraries.
#  I'm not entirely sure how necessary this is but it fixes broken signiture checksums after using strip.
#  Info: https://github.com/indygreg/PyOxidizer/tree/main/apple-codesign
#  Download page: https://github.com/indygreg/PyOxidizer/releases/tag/apple-codesign%2F0.17.0
#
# 3. If building SDL < 2.24.0, you can also build Universal 1 dylib with ppc/x86/x86_64.
# If you haven't yet, rename osxcross/target/ to osxcross/target-11.3/
# Repeat osxcross set up with macOS 10.13 SDK. Rename osxcross/target/ to osxcross/target-10.13/.
#
# For Universal 1, you need to extract the SDL 2.0.1 ppc build from ioq3.
# git clone https://github.com/ioquake/ioq3
# mkdir ./ztm-libs-ioq3-prebuilt-ppc
# x86_64-apple-darwin17-lipo -extract ppc ioq3/code/libs/macos-ub/libSDL2-2.0.0.dylib -o ./ztm-libs-ioq3-prebuilt-ppc/libSDL2-2.0.0.dylib
# x86_64-apple-darwin17-lipo -extract ppc ioq3/code/libs/macos-ub/libSDL2main.a -o ./ztm-libs-ioq3-prebuilt-ppc/libSDL2main.a

# For building macOS libraries; change for your system.

REM   Workloads: "Desktop development with C++"
REM   Individual Commponents: "C++ Windows XP Support for VS 2017 (v141) tools" aka v141_xp
REM If VS is already installed, you can add them in Visual Studio using menubar, Tools, Get Tools and Features...

REM This script can be placed anywhere. The libries are copied to .\ztm-libs\msvc\{win32,win64}.
