Revamp the build system. This achieves several goals: * Less reliance on scripts so we have better portability to Windows (though we still have a ways to go for proper Windows support). Luajit, luarocks, moonscript, and busted are all installed via CMake now. * Trying to make use of pkg-config to get the correct libraries. The latest libuv is still broken in this regard, but we'll at least be in a position to use it. * Allow the use of Ninja or make. The former runs faster in many environments, and automatically makes use of parallel builds. This also allows for system installed dependencies--though not through the Makefile just yet--and adds support for FreeBSD. This also make us build libuv and luajit as static libraries only, since we're only concerned about having static libraries for our bundled dependencies.

Fix #867: cmake doesn't issue `-isystem` for versioned gcc CMake purposefully disables the use of the `-isystem` flag on Apple platforms, but it's overly blunt with the detection. Apple's compilers have supported the flag since at least 10.4. Let's force the switch to be on when gcc/g++ is detected on an Apple platform to reduce the warnings out of the msgpack-related bits.

Turn off -Werror by default. It inteferes with development activities by breaking your build in the middle of a refactor. Instead, let's enable -Werror on the Travis CI builds via a TRAVIS_CI_BUILD option.

Use CMAKE_C_FLAGS variable to set compiler flags. If the compiler is some GNU-alike variant, set the compiler flags to use the gnu99 dialect of C and enable all warnings. Non-GNU compilers may have to have their own magic added to set dialect and enable warnings. Closes #179.
2014-02-27 05:27:20 -07:00
Add automatic generation of headers - The 'stripdecls.py' script replaces declarations in all headers by includes to generated headers. `ag '#\s*if(?!ndef NEOVIM_).*((?!#\s*endif).*\n)*#ifdef INCLUDE_GENERATED'` was used for this. - Add and integrate gendeclarations.lua into the build system to generate the required includes. - Add -Wno-unused-function - Made a bunch of old-style definitions ANSI This adds a requirement: all type and structure definitions must be present before INCLUDE_GENERATED_DECLARATIONS-protected include. Warning: mch_expandpath (path.h.generated.h) was moved manually. So far it is the only exception.

link to rt if it provides clock_gettime As noted in #128, if clock_gettime is provided by librt then it does not end up being linked into the static libuv.a binary. This might be considered a bug in libuv but we can address it here. Detect if librt provides the clock_gettime symbol and, if so, append it to the list of libraries linked into nvim. On non-librt systems the behaviour should be as before.
