DeepSea-libs provides scripts to build the external libraries dependencies for compiling DeepSea. Pre-compiled releases are provided for the following platforms:
- Linux for x86-64 (glibc 2.31 or later, e.g. Ubuntu 20.04)
- macOS for x86-64 and arm64 (10.11 or later)
- Windows for x86 and x86-64 with VS 2015 runtime.
- Android for x86, x86-64, armeabi-v7a, and arm64-v8a.
This builds the following libraries:
- HarfBuzz (not built for Linux)
- FreeType (not built for Linux)
- SDL (not built for Linux)
- Google Test
The following software is required to build DeepSea-libs:
- cmake 3.1 or later. This must be in your
PATH. - 7zip is required on Windows.
- Powershell is required on Windows.
- curl is required on Linux and macOS.
Scripts are provided to perform the compilation on various platforms.
Make sure the development tools and dependencies are installed.
For example, on Ubuntu the following packages should be installed:
- cmake
- build-essential
For macOS using Homebrew, the following packages should be installed:
- cmake
To perform the build, simply run the build.sh script. Additional CMake options can be passed in as command line options, such as for cross-compiling for other systems. Once finished, the DeepSea-libs.tar.gz package will contain the libraries.
Note: If you want to keep a script around for custom arguments without checking it into source control, create a script named
build-custom.sh. This is in.gitignoreso it won't show as a locally modified file.
To perform the build, simply run the build.bat script. Additional CMake options can be passed in as command line options, such as for cross-compiling for other systems. Once finished, the DeepSea-libs.zip package will contain the libraries.
Note: If you want to keep a script around for custom arguments without checking it into source control, create a script named
build-custom.bat. This is in.gitignoreso it won't show as a locally modified file.
Custom build scripts can be used to control the version of the compiler used. For example, to use a newer compiler or support older systems.
Building for Android requires passing in the SDK location. A build-custom-android.sh script like this can be used to avoid passing in the path each time, and also build for each available ABI.
#!/usr/bin/env bash
set -e
NDK_DIR=$HOME/Android/Sdk/ndk-bundle
ABIS=(x86 x86_64 armeabi-v7a arm64-v8a)
for ABI in "${ABIS[@]}"
do
./build.sh -p android --android-ndk "$NDK_DIR" --android-abi $ABI \
-o DeepSea-libs-android-$ABI.tar.gz
done
Building for iOS is very straight forward. The following is an example build-custom.sh that can be used:
#!/bin/sh
set -e
./build.sh -p ios -o DeepSea-libs-ios.tar.gz
In order to support earlier than the current version of macOS (such as back in the ye olde days when it was still called Mac OS X), you need to download an older version of XCode. You can download rather old versions of XCode from Apple's developer website, though it's quite limited how far back will actually run on a modern system. When running macOS 10.14, the furthest back I could go is XCode 7.3.1. This would allow building against the Mac OS X 10.11 SDK.
In order to use an older version of XCode, download it, rename XCode.app to a different name (e.g. XCode-7.3.1.app), and move it to /Applicatons. You should also run it in order to make sure the command line tools are installed.
Once an older version is installed, a build-custom.sh such as the following can be used:
#!/bin/sh
set -e
export DEVELOPER_DIR=/Applications/Xcode-7.3.1.app/Contents/Developer
./build.sh -DCMAKE_OSX_SYSROOT=$DEVELOPER_DIR/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk -o DeepSea-libs-mac.tar.gz
Windows is configured to build for 32-bit by default. You can also build for 64-bit by specifying the "win64" platform. The following is an example build-custom.batch script that can be used:
@echo off
.\build.bat -p win64 -o DeepSea-libs-win64.zip
