Support for Swift open source project (CMake) #84

Open danielmartin opened 8 years ago

danielmartin commented 8 years ago

I've tried YCM-Generator with the Swift open source project at https://github.com/apple/swift (based on CMake), but the following error occurs:

CMake Error at cmake/modules/SwiftUtils.cmake:94 (message):
  Unknown build type:
Call Stack (most recent call first):
  CMakeLists.txt:89 (is_build_type_optimized)

-- Configuring incomplete, errors occurred!

Your build system may not be compatible.

How can we investigate this problem further? Thank you.

It's failing because Swift doesn't use Cmake as the top-level build system - you'll get the same error if you run cmake . in the directory. The README for Swift says that it should be built using ./utils/build-script. The best way of handling this is to figure out what flags cmake is called with and pass them to it.

Running ./utils/build-script -R -n produces the following (once you've checked out the other sources as indicated in the README):

./swift/utils/build-script -R -n                                                                      15:50:36

Judging by that, you'll need to use -e to preserve the environment variables, and use -C to pass in the cmake options. I suggest you figure out how to run cmake directly first, before you try to make YCM-Gen work. I have no idea how much effort it'll take though.
