Get prefix to a -D_FORTIFY_SOURCE string if it is present in
CFLAGS and apply the prefix to flags added to redefine
_FORTIFY_SOURCE in CFLAGS and CPPFLAGS
* fixes 1569
Some builds don't use Release (such as Gentoo, though it can be told
to). So let's go a bit further and probe the compiler to see if we need
to turn down the _FORTIFY_SOURCE level.
- If possble try to abstract away from Make, and use cmake --build
- third-party still needs to find Make to build some components
- Removed search for Make from CMakeLists.txt
* for CMake < 3.0 --build has no color output
Fixes#1447. `CMAKE_MODULE_PATH` is meant to be a list of directories,
and as such, is not the proper way to launch our scripts. Let's use
`${PROJECT_SOURCE_DIR}/cmake` instead. Also, let's not outright set
`CMAKE_MODULE_PATH`, but instead append our location to the list.
Commit a1d411f9c9 just assumes that gcc
will support the `-Og` option, but gcc that comes with Ubuntu 12.04 does
not. Let's check to see if the flag is supported, and then decide
whether to enable it or not.
Unfortunately, we can't force the specific inclusion of a header file.
So if anything add /opt/local/include to the include path--such as
libintl--then other dependencies might be drawn from /opt/local at
compile time, even though we detected them elsewhere at configure time.
This, in turn, causes issues with mixed versions, such as the iconv.h
header being pulled from /opt/local/include, but linked against the
library in /usr/lib--which can be mismatched versions.
So, despite CMake's best effort to treat /sw and /opt/local as just
another system area, we really need to give them preferential treatment.
To do this, we add them to CMAKE_PREFIX_PATH.
This fixes an issue discovered while re-enabling iconv in #1370.
The -O3 optimization level can often lead to dangerous (and sometimes
incorrect) optimizations being performed. So let's use a level that's
more stable.
If you aren't just building everything into build/, then the functional
tests fail because they can't find the nvim executable. Let's pass in
the location of the nvim executable, and set NVIM_PRG environment
variable accordingly.
Remove build warning:
The target name "test" is reserved or not valid for certain CMake
features, such as generator expressions, and may result in undefined
behavior.
Now that the lua client is available, python/lupa are no longer necessary to run
the functional tests. The helper functions previously defined in
run-functional-tests.py were adapted to test/functional/helpers.lua.
- cmake: git_timestamp() returns last commit time formatted as
`YYYYMMddHHmm`.
- Always include commit hash in :version and --version output.
`nvim --version` sample output:

Commit: f747b2b1ff7bfe7eb00cc2be82d7af87c98f1111
The 'lupa' python package provides a simple way to seamless integrate lua and
python code.
This commit replaces vroom by a python script that exposes the 'neovim' package
to a lua state, and invokes busted to run functional tests. This is a temporary
solution that will enable writing functional tests using lua/bused while a lua
client library is not available.
The reason for dropping vroom is flexibility: Lua/busted has a nice DSL-style
syntax while also providing the customization power of a full programming
language. Another reason is to use a single framework for unit/functional tests.
Two other changes were performed in this commit:
- Instead of "gcc-unittest/gcc-ia32", the travis builds for gcc are now
identified by "gcc/gcc-32". They will run unit/functional tests for both 64
and 32 bits.
- Old integration tests(in src/nvim/testdir) are now ran by the 'oldtest' target
The install() command will create the parent directories, but it does so
with the user's umask. We want to do our best to make sure the correct
permissions are being set, without clobbering existing permissions.
To do this, this commit introduces an install_helper(), which is similar
in signature to the install() command, to help ensure that directories
are created ahead of the actual install() command. This will attempt to
use 0644 permissions for files and 0755 permissions for directories by
default--though they can be overridden.
To make this work correctly, without trying to introduce some mechanism
with setting the umask, it meant that there's a small portion that makes
use of an "internal" version of the file() command. It has been tested
on CMake 2.8.11, 2.8.12, and 3.0.2, and works correctly on all versions.
This fixes#1201 and #1086.
`-Wstrict-prototypes` warn if a function is declared or defined without
specifying the argument types.
This warning disallow function prototypes with empty parameter list.
In C, a function declared with an empty parameter list accepts an
arbitrary number of arguments when being called. This is for historic
reasons; originally, C functions didn't have prototypes, as C evolved
from B, a typeless language. When prototypes were added, the original
typeless declarations were left in the language for backwards
compatibility.
Instead we should provide `void` in argument list to state
that function doesn't have arguments.
Also this warning disallow declaring type of the parameters after the
parentheses because Neovim header generator produce no declarations for
old-stlyle prototypes: it expects to find `{` after prototype.
- When USE_BUNDLED=OFF and the system has multiple lua interpreters
(luajit AND lua) it may occur that only the later has the needed
dependencies (lua-lpeg, lua-cmsgpack). If we pick luajit then
finding the dependencies FAILS.
- This commit groups detection of the lua interpreter with the lua
dependencies it tries to find them for both the interpreters and
choses the first one that has them.

This is in preparation for the next step, which is to find a suitable
lua interpreter, rather than just erroring when an interpreter is found
but doesn't have the necessary dependencies.

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.
Stop forcing some platform setting that are really intended to be used
for Travis CI. Under other systems, like Arch Linux, it prevents
dependencies from being correctly located.
- 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.
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.
- Leave src as include dir (for includes to recognize 'nvim/' prefix).
- Change subdirectory from src to src/nvim.
- Fix msgpack generation.
- Fix some other paths to new locations.
This adds the `SYSTEM` parameter to `include_directories`, which will tell cmake
to use `-isystem` instead of `-I` for specifying include directories. One
advantage is that compilers won't emit warnings for included files that belong
to dependencies.
This allows us to avoid hard-coding paths and using environment
variables to communicate key information to unit tests, which fits
with the overall goal of making sure that folks driving CMake directly
can continue to do out-of-tree builds.
- Build targeting 32-bit with travis
- Code in `before_install`/`after_success` was moved to travis.sh since it
provides greater flexibility for detecting the build matrix environment. This
improves the build speed since we now install only what's necessary.
- Now clint has a dedicated travis worker
Apparently busted 1.11.0 is broken(https://github.com/Olivine-Labs/busted/issues/236)
in a way that is causing the unit tests to fail. This pins the version to 1.10.0
and also fixes a wrong variable set when msgpack was added as a dependency
A lua executable is now required for the build process since a lpeg-based script
is used for generating a dispatch function and metadata for the msgpack API
frontend. This removes the need for setting the LUA_BINARY environment variable.
Fixes#518.
