macOS 10.14.5 Ddlopen Error

[jeremyforan]

I was able to compile and flash but I am getting the following error when trying to run the script.

seems have to build the libamiibo under OSX. and you should modify this line in "CMakeLists.txt"

-target_link_libraries(luamiibo crypto) +target_link_libraries(luamiibo crypto lua)

Sorry for the late response, the included libluamiibo.so is built for Linux. I was able to build the library on Mac OS X Catalina with these steps:

1. Clone this repo
2. Clone https://github.com/jamchamb/amiitool.git
3. Get cmake and openssl so you can build amiitool: brew install cmake openssl
4. Go to the amiitool directory and git checkout lua-lib
5. Open CMakeLists.txt and set the PROXMARK_LIBLUA path setting to the liblua directory in the proxmark3 repo. For example I changed it to: set(PROXMARK_LIBLUA "~/git/proxmark3-amiimicyou/liblua/")
6. At this point I had some issues building with the openssl libraries installed from homebrew and getting dynamic linking to Lua to work. Here's a patch I made for the CMakeLists.txt file:

Make sure to fix your PROXMARK_LIBLUA path again after applying this patch.

Then instead of running build.sh I go to the amiitool directory and run:

$ rm -rf build && mkdir build && cd build
$ cmake -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl -DOPENSSL_LIBRARIES=/usr/local/opt/openssl/lib ..
$ make

It should finish successfully and generate libluamiibo.dylib. Copy this to the proxmark3-amiimicyou/client directory and then update the Lua scripts to use this instead of the .so file.
