Prepare ndk development environment Download CMake Build absl Build this project

d3xMachina commented 8 months ago

I tried on both Windows 11 and on a debian 12 VM and I'm having the same error message. I would like to build a "zygisk_module.zip" like in the release page.

Here is what I did on Debian :

I installed Android NDK and confirmed it works (ndk-build --version command works) by following instructions here
I installed CMake

sudo apt install cmake

I built absl following official instructions here :

cd ~/android/src
git clone https://github.com/abseil/abseil-cpp.git
cd abseil-cpp
mkdir build && cd build
cmake -DABSL_BUILD_TESTING=ON -DABSL_USE_GOOGLETEST_HEAD=ON -DCMAKE_CXX_STANDARD=14 ..
cmake --build . --target all

ctest command confirms every tests succeeded for absl

I tried to build this project :

git clone https://github.com/abseil/abseil-cpp.git
cd abseil-cpp
mkdir build && cd build
cmake -Dabsl_DIR=~/android/src/abseil-cpp/build -DCMAKE_BUILD_TYPE=Release ..

I get the error :

-- Release Version -- CMAKE_PREFIX_PATH:/x86_64-linux-gnu CMake Error at /home/dev/android/src/abseil-cpp/build/abslConfig.cmake:32 (include): include could not find requested file: /home/dev/android/src/abseil-cpp/build/abslTargets.cmake Call Stack (most recent call first): UnityFPSUnlocker/CMakeLists.txt:64 (find_package)

-- Configuring incomplete, errors occurred!

The abslConfig.cmake in the absl build directory has the line :

include ("${CMAKE_CURRENT_LIST_DIR}/abslTargets.cmake")

but the abslTargets.cmake file doesn't exist.

Also in the CMakeLists.txt of this project there is :

find_library(log-lib log)

How to get this dependency ?

My bad, my description is not detailed enough. I am using VSCode for development, but if you're building from the command line, it is a bit complex.

For windows: Download the source codes for absl-cpp and UnityFPSUnlocker, and unzip them into the same directory (for example, D:\UnityFPSUnlocker-zygisk_module).

tree -n -d -L 1
.
├── abseil-cpp-20230802.1
└── UnityFPSUnlocker

First, build absl

cd abseil-cpp-20230802.1
mkdir build
cd build

set environment

set ABI=arm64-v8a
set ANDROID_NDK=D:\android-ndk-r25c

and build

cmake -DCMAKE_TOOLCHAIN_FILE=%ANDROID_NDK%/build/cmake/android.toolchain.cmake -DANDROID_ABI=%ABI% -DCMAKE_ANDROID_ARCH_ABI=%ABI% -DANDROID_PLATFORM=android-28 -DANDROID_NDK=%ANDROID_NDK% -DCMAKE_CXX_STANDARD=17 -DCMAKE_BUILD_TYPE=Release -GNinja ../

cmake --build . --config Release

install to sysroot

cmake --install . --prefix %ANDROID_NDK%/toolchains\llvm\prebuilt\windows-x86_64\sysroot\aarch64-linux-android\absl

now build UnityFPSUnlocker

cd D:\UnityFPSUnlocker-zygisk_module\UnityFPSUnlocker
mkdir build
cd build

cmake -DCMAKE_TOOLCHAIN_FILE=%ANDROID_NDK%/build/cmake/android.toolchain.cmake -DANDROID_ABI=%ABI% -DCMAKE_ANDROID_ARCH_ABI=%ABI% -DANDROID_PLATFORM=android-28 -DANDROID_NDK=%ANDROID_NDK% -DCMAKE_CXX_STANDARD=17 -DCMAKE_BUILD_TYPE=Release -GNinja ../

cmake --build . --config Release

after last command, you'd see this output:

D:\UnityFPSUnlocker-zygisk_module\UnityFPSUnlocker\build>cmake --build . --config Release
[13/13] Linking CXX shared library D:\UnityFPSUnlocker-zygisk_module\UnityFPSUnlocker\libs\arm64-v8a\libUnityFPSUnlocker.so

I'm not use gradle, so you need to replace this binary file manually. Rename D:\UnityFPSUnlocker-zygisk_module\UnityFPSUnlocker\libs\arm64-v8a\libUnityFPSUnlocker.so to arm64-v8a.so and replace it to zygisk_module.zip/zygisk/arm64-v8a.so

Thanks for the instructions, I've managed to build it. I had to download and set ninja too.

I've made a batch script to build every ".so" and rename them correctly. They are put in "UnityFPSUnlocker\libs". Your tree must look like : . │ build.bat │ ninja.exe │ ├───abseil-cpp ├───android-ndk └───UnityFPSUnlocker

I got ninja.exe from the archive here.

Here is the script (save as a build.bat) :

@echo off
