tips: any question go to Discord
1. Build & Compile
1.0 Clone the project
git clone --branch dev --depth 1 git@github.com:jmpews/HookZz.git
1.1. Use BuildScript for iOS 64 & Simulator 64
cd BuildScript
sh ./build_64_fat_macho.sh
1.2. Build for iOS/ARM64
mkdir temp_build_aarch64
cd temp_build_aarch64
cmake .. \
-DCMAKE_TOOLCHAIN_FILE=cmake/ios.toolchain.cmake \
-DPLATFORM=OS64 \
-DARCHS=arm64 \
-DENABLE_BITCODE=0 \
-DENABLE_ARC=0 \
-DENABLE_VISIBILITY=0 \
-DDEPLOYMENT_TARGET=9.3 \
-DCMAKE_SYSTEM_PROCESSOR=aarch64 \
-DSHARED=ON \
-DHOOKZZ_DEBUG=OFF
make -j4
if you want generate Xcode Project, just replace with cmake -G Xcode .
1.3. Build for Android, arm64-v8a
export ANDROID_NDK=/Users/jmpews/Library/Android/sdk/ndk-bundle
cmake .. \
-DCMAKE_TOOLCHAIN_FILE=$ANDROID_NDK/build/cmake/android.toolchain.cmake \
-DCMAKE_BUILD_TYPE=Release \
-DANDROID_ABI="arm64-v8a" \
-DANDROID_NATIVE_API_LEVEL=android-21 \
-DSHARED=ON \
-DHOOKZZ_DEBUG=OFF
make -j4
1.4. Build for Android, armeabi-v7a
export ANDROID_NDK=/Users/jmpews/Library/Android/sdk/ndk-bundle
cmake .. \
-DCMAKE_TOOLCHAIN_FILE=$ANDROID_NDK/build/cmake/android.toolchain.cmake \
-DCMAKE_BUILD_TYPE=Release \
-DANDROID_ABI="armeabi-v7a" \
-DANDROID_STL=c++_static \
-DANDROID_NATIVE_API_LEVEL=android-14 \
-DSHARED=ON \
-DHOOKZZ_DEBUG=OFF
make -j4
2. Example
2.1. Example for iOS 64 & Simulator 64
Ref: iOS/AArch64.ARMv8
2.2. for HOST
Ref: HOST
use cmake .. is done.
3. Usage
3.1. replace hook function
extern "C" {
extern int ZzReplace(void *function_address, void *replace_call, void **origin_call);
}
size_t (*origin_fread)(void * ptr, size_t size, size_t nitems, FILE * stream);
size_t (fake_fread)(void * ptr, size_t size, size_t nitems, FILE * stream) {
// Do What you Want.
return origin_fread(ptr, size, nitems, stream);
}
void hook_fread() {
ZzReplace((void *)fread, (void *)fake_fread, (void **)&origin_fread);
}
4. Known Issues
4.1. Android / ARM
4.1.1. not fixed pld
4.2 x86
x86_64 is tested, but not x86.
