Question

We are compile the eosio.contract v1.2.0 using Clion by following that:

Dependencies:
eosio v1.1.2
eosio.wasmsdk v1.1.0

Cannot get compiler information:

The CMake Options that I am using to execute is: -G Ninja -DLLVM_DIR=/usr/local/Cellar/llvm@4/4.0.1/lib/cmake -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_C_COMPILER=clang -DWASM_ROOT=/usr/local/wasm -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl -DBUILD_MONGO_DB_PLUGIN=true -DENABLE_COVERAGE_TESTING=false -DBUILD_DOXYGEN=false

Answer 1

I think there are two things going on:

1. I've run into problems with Ninja and eosio.wasmsdk. Give make a shot instead of ninja.

2. Those options look like they're for compiling the compiler, not for compiling a smart contract. Can you build something like the exchange example (https://github.com/EOSIO/eosio.wasmsdk/tree/master/examples/exchange) without those extra cmake options?
