Caution

This is a general procedure, and depending on your environment, you will probably, or rather definitely, need to adjust your build settings.

how to build Native Library

Prerequisites

Navigate to <repo_root>/limbo-android-lib/src/main/jni and download:

• glib: 2.56.1 only (autotools last supported in 2.59.0)
• SDL2: 2.0.8 only (configure-based build)
• QEMU: 5.1.0
• pixman: 0.42.2+ (autotools compatible)
• libffi: recent versions (autotools supported)

Note

glib 2.59.1+ switched to meson exclusively. Patch files are required for compatibility.

Apply patches from the patches/ directory:

• patch -p1 < ../patches/glib-2.56.1.patch
• patch -p1 < ../patches/sdl2-2.0.8.patch
• patch -p1 < ../patches/qemu-5.1.0.patch

Tip

Apply patches correctly - the build will fail otherwise. (Obviously...)

Configure Guest OS Architecture and Android ABI

Run this command to check available options:

grep "EXPORT_GUEST_ALL\|BUILD_HOST" <repo_root>/limbo-android-lib/src/main/jni/Makefile

You should see output similar to:

Build_Guest

• x86_64-softmmu
• aarch64-softmmu
• ppc64-softmmu
• sparc-softmmu

Build_Host

• arm64-v8a
• armeabi-v7a
• x86
• x86_64

Setting

Set your desired values:

export BUILD_HOST=<desired_value>
export BUILD_GUEST=<desired_value>

Build

Navigate to <repo_root>/limbo-android-lib/src/main/jni/ and run:

make 

Note

You may need to run autoreconf -fiv in each library directory after extracting/patching: This regenerates the configure scripts with the latest autotools.
