CMake defaults to C *and* C++ toolchain, in case nothing has been specified.
This means that cmake always checks for both, which is more than needed.
This PR cuts off C toolchain requirement from /CMakeLists.txt and ensures that we
don't pass along any `..._C_...` variables in EthCompilerSettings.cake nor jsoncpp.cmake.
Removed push/pop if there was no change to the warnings *in the same
file* for a given compiler. This assumes the imported boost headers use
a warning stack themselves.
The pragmas don't seem to be required anymore, but were not removed to
mantain compatibility with older versions of the boost library.
Compiled with
- clang version 6.0.1 (tags/RELEASE_601/final)
- gcc (GCC) 8.1.1 20180531
against:
- libboost 1.67.0-5
This also removed PROFILE option that also adds --coverage flag. Instead you can use -DCMAKE_EXE_LINKER_FLAGS=-lprofiler. The profiling options can be added back when better investigated (e.g. -lprofiler vs -pg options).
In my system I have gcc 7.1.1 and there I get a lot of warnings which
fail the build due to implicit fallthroughs in switch statements.
Some examples can be seen here:

This PR proposes a simple solution, which is to ignore the warning for
both gcc and clang.
This commit is the culmination of several months of work to decouple Solidity from the webthree-umbrella so that it can be developed in parallel with cpp-ethereum (the Ethereum C++ runtime) and so that even for the Solidity unit-tests there is no hard-dependency onto the C++ runtime.
The Tests-over-IPC refactoring was a major step in the same process which was already committed.
This commit contains the following changes:
- A subset of the CMake functionality in webthree-helpers was extracted and tailored for Solidity into ./cmake. Further cleanup is certainly possible.
- A subset of the libdevcore functionality in libweb3core was extracted and tailored for Solidity into ./libdevcore. Further cleanup is certainly possible
- The gas price constants in EVMSchedule were orphaned into libevmasm.
- Some other refactorings and cleanups were made to sever unnecessary EVM dependencies in the Solidity unit-tests.
- TravisCI and Appveyor support was added, covering builds and running of the unit-tests (Linux and macOS only for now)
- A bug-fix was made to get the Tests-over-IPC running on macOS.
- There are still reliability issues in the unit-tests, which need immediate attention. The Travis build has been flipped to run the unit-tests 5 times, to try to flush these out.
- The Emscripten automation which was previously in webthree-umbrella was merged into the TravisCI automation here.
- The development ZIP deployment step has been commented out, but we will want to read that ONLY for release branch.
Further iteration on these changes will definitely be needed, but I feel these have got to sufficient maturity than holding them back further isn't winning us anything. It is go time :-)
