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.
Dependency headers for OSes needed anchors to work with links from
content list. Reordered OSes in content list to match headers
(all Linuxes first, Mac OS X last)
- Some systems have the FindCurses.cmake module to find
the curses/ncurses libraries using find_package(). And
in some CheckLibraries is not very reliable, so as
fallback FindCurses is now used if no other option
works.
If LibUV_USE_STATIC is set then the static libuv library will be
preferred to the shared library. This is useful when building with the
bundled libuv but is less useful when building with a system libuv.
Change an explicit ``cd build && make`` into the more usual
``${MAKE} -C build`` style of invoking make in a subdirectory. This
should mean that ``make -jN`` from the top-level Makefile should work.
Closes#162.
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.
Explicitly try to find the static libuv library first.
This might be considered a hack and if it weren't a single-use module it
might be preferable to control static versus shared preferences with a
configuration variable.
We use the standard CMAKE_PREFIX_PATH variable to pass the location of
.deps as a search location on the command line. There is now no need for
explicitly hard-coding it.
The CMake prefix path is the set of directories CMake searches for
libraries, header files, etc. Use the .deps directory we create when
building libuv as one of those locations.
This commit removes a K&R promoted parameter error, the final warning
I have when building.
I realize that this creates only one function that is written in a
different style, but I thought it might be worth it to have a warning
free build.
See #137 for the issue.
Every header in the proto directory was:
* Given include guards in the form
#ifndef NEOVIM_FILENAME_H
#define NEOVIM_FILENAME_H
...
#endif /* NEOVIM_FILENAM_H */
* Renamed from *.pro -> *.h
* Moved from src/proto/ to src/
This would have caused conficts with some existing headers in src/;
rather than merge these conflicts now (which is a whole other can of
worms involving multiple and conditional inclusion), any header in src/
with a conflicting name was renamed from *.h -> *_defs.h (which may or
may not actually describe its purpose, the change is purely a
namespacing issue).
Once all of these changes were made a script was developed to determine
what #includes needed to be added to each source file to describe its
dependencies and allow it to compile; because the script is so short
and I'll just list it here:
#! /bin/bash
cd $(dirname $0)
# Scrapes `make` output for provided error messages and outputs #includes
# needed to resolve them.
# $1 : part of the clang error message between filename and identifier
list_missing_includes() {
for file_missing_pair in $(CC=clang make 2>&1 >/dev/null | sed -n "s/\/\(.*\.[hc]\).*$1.*'\(.*\)'.*/\1:\2/p"); do
fields=(${file_missing_pair//:/ })
source_file=${fields[0]}
missing_func=${fields[1]}
# Try to find the declaration of the missing function.
echo $(basename $source_file) \
\#include \"$(grep -r "\b$missing_func __ARGS" | sed -n "s/.*\/\(.*\)\:.*/\1/p")\"
# Remove duplicates
done | sort | uniq
}
echo "Finding missing function prototypes..."
list_missing_includes "implicit declaration of function"
echo "Finding missing identifier declarations..."
list_missing_includes "use of undeclared identifier"
Each list of required headers was added by hand in the following format:
#include "vim.h"
#include "*_defs.h"
#include "filename.h"
/* All other includes in same module here, in alphabetical order. */
/* All includes from other modules (e.g. "os/*.h") here in alphabetical
* order. */
