How to Build Dopamine 3.0.7 from Source on macOS

Dopamine is one of the most active open-source projects in the iOS jailbreak community. With the 3.x line expanding support across more modern iOS versions, building Dopamine from source has become a useful exercise for jailbreak developers and security researchers.

In practice, this is not just a matter of cloning the repository and running make. The build depends on Theos, patched SDKs, several low-level tools, and a few environment-specific workarounds. This guide walks through a full macOS setup for building Dopamine 3.0.7 and highlights the failure points that are easy to miss.

Preparation: Environment and Dependencies

Building Dopamine depends heavily on the Theos toolchain and several supporting C/C++ packages.

Install basic dependencies with Homebrew

Make sure Homebrew is available, then install the core packages:

brew install git ldid dpkg libarchive pkg-config

Common issue: missing pkg-config

If pkg-config is not installed, some dependency builds will fail with a Command not found error. Installing it through Homebrew resolves that immediately.

Configure libarchive

The default archive tooling on macOS is not sufficient for this build flow. Use the Homebrew-provided libarchive headers and libraries instead:

export CFLAGS="-I$(brew --prefix libarchive)/include"
export LDFLAGS="-L$(brew --prefix libarchive)/lib"

Set Up Theos and the SDK

Install Theos

Theos is the standard build system for jailbreak-oriented iOS development:

export THEOS=~/theos
git clone --recursive https://github.com/theos/theos.git $THEOS
export PATH=$THEOS/bin:$PATH

Use a patched iOS 16.5 SDK

Dopamine relies on a large number of Apple private APIs. The default SDK shipped with Xcode is usually not enough and may fail during linking. In practice, you need a patched community SDK.

You can fetch iPhoneOS16.5.sdk.tar.xz from theos/sdks, then extract and move it into the Theos SDK directory:

mkdir -p $THEOS/sdks
mv iPhoneOS16.5.sdk $THEOS/sdks/

Critical Build Pitfalls

Before building Dopamine itself, it helps to resolve a few recurring environment problems up front.

Pitfall 1: Missing trustcache

The Dopamine build process needs to generate TrustCache files, but the required trustcache binary is not included by default in either macOS or Theos.

If you try to build without it, you will usually see:

trustcache: No such file or directory

Build and install it manually:

cd ~/projects
git clone https://github.com/CRKatri/trustcache.git
cd trustcache
make
mkdir -p ~/.local/bin
cp trustcache ~/.local/bin/
export PATH=~/.local/bin:$PATH

Pitfall 2: ldid assertion error

If you use the default Saurik ldid package from Homebrew, entitlement signing may fail with an error similar to:

ldid.cpp(3335): _assert(): flag_S

In practice, switching to the Procursus build avoids this:

brew uninstall ldid
brew install ldid-procursus

Pitfall 3: Antivirus silently removing object files

This one is especially easy to misread. During builds involving exploit modules such as multicast_bytecopy or kfd, the terminal may look normal at first, but the linker later reports that expected .o files do not exist.

On some macOS setups, antivirus or endpoint protection software can treat these generated files as suspicious and delete them immediately after creation.

The simplest fix is to add both the Dopamine source tree and the Theos directory to your antivirus exclusions, or temporarily disable real-time protection during compilation.

Pitfall 4: Xcode script sandbox restrictions

Recent Xcode versions enable stricter script sandboxing. That can break custom build script steps and produce Operation not permitted errors.

The workaround is to adjust the Dopamine build configuration:

  1. Update the xcodebuild command in Application/Makefile to include:
ENABLE_USER_SCRIPT_SANDBOXING=NO OTHER_LDFLAGS="-Wl,-no_adhoc_codesign"
  1. Replace the install_name_tool script steps inside Dopamine.xcodeproj/project.pbxproj with a harmless placeholder:
cd Application
sed -i '' 's/shellScript = "install_name_tool.*/shellScript = "echo Hello";/g' Dopamine.xcodeproj/project.pbxproj

Clone the Source Code

When pulling the Dopamine repository, make sure to include submodules. Without them, dependent projects such as ChOma will be missing and the build will fail with missing-header errors.

cd ~/projects
git clone --recursive https://github.com/opa334/Dopamine.git
cd Dopamine

Download the Bootstrap Files

The repository does not include the full bootstrap environment required by the jailbreak app. Download it separately from the provided helper script:

cd Application/Dopamine/Resources
./download_bootstraps.sh
cd ../../..

Build Dopamine

Build the default Debug version

make

Build a Release package

By default, make produces a Debug build. If you want a release-oriented package for end users:

  1. Edit Application/Makefile and replace every Debug-iphoneos occurrence with Release-iphoneos
  2. Add -configuration Release to the xcodebuild command
  3. Build again with FINALPACKAGE=1
make clean
make FINALPACKAGE=1

Output Files

If the build succeeds, you should find the final artifacts in the Application directory:

  • Dopamine.ipa
  • Dopamine.tipa

Conclusion

Building Dopamine from source is mostly an exercise in environment preparation. Once Theos, the patched SDK, signing tools, and sandbox workarounds are all in place, the actual compile step is fairly direct.

If you are working on iOS jailbreak development or studying how modern jailbreak tooling is assembled, going through this process is worth the time. It gives you a much clearer view of how the packaging, signing, and private-framework assumptions fit together.
