Notes on Building the Binary Ninja Architectures

# Get the necessary repositories:

mkdir ~/repos/vector35
cd ~/repos/vector35
git clone git@github.com:Vector35/binaryninja-api.git
git clone git@github.com:Vector35/arch-armv7.git

# Set environment variables

export BN_API_PATH=~/repos/vector35/binaryninja-api

# Build

cd arch-armv7
cmake -DBN_INSTALL_DIR=/Applications/Binary\ Ninja\ DEV.app/ .
make

# Troubleshooting

    CMake Error at CMakeLists.txt:8 (message):
      Provide path to Binary Ninja API source in BN_API_PATH
    resolution:
    ensure BN_API_PATH is in your environment

# Troubleshooting

    CMake Error at /Users/andrewl/repos/vector35/binaryninja-api/CMakeLists.txt:53 (message):
      Binary Ninja Core Not Found
    resolution:
    ensure BN_INSTALL_DIR is supplied at command line invocation of cmake
    ensure some bad directory is not cached in CMakeCache.txt

# Troubleshooting

    cmake seems to ignore your setting of BN_INSTALL_DIR and other cmake variables
    resolution:
    rm CMakeCache.txt

# Troubleshooting

    undefined symbols at link time, like:
    Undefined symbols for architecture x86_64:
      "_BNClearUserVariableValue", referenced from:
      BinaryNinja::Function::ClearUserVariableValue(BinaryNinja::Variable const&, unsigned long long) in libbinaryninjaapi.a(function.cpp.o)
    resolution:
    ensure that your api repo is on the same channel and at the same commit as the libbinaryninjacore you're linking against
    eg: binaryninja is on dev update channel and is up-to-date and binaryninja-api repo is on branch dev with latest pulled
