If `libintl` is a static library on macOS, we also need to explicitly
link with `libiconv` and the `CoreFoundation` framework. Otherwise, our
`HAVE_WORKING_LIBINTL` test erroneously fails.
Closes#19127Closes#19138
Problem: On Windows with the MSVC build, gettext-translation
"Questa è già la" displays as "Questa <e8> gi<e0> la".
Solution: Fix iconv detection iconv when building gettext.
So HAVE_ICONV is correctly defined when building nvim.
* fix gettext mb chars on MSVC
* fix libintl detection failure on MSVC
fixes#11749
* build: FindLibIntl: fix warning about CMP0075
The common pattern elsewhere to set this only during the check, and here
it was not unset, resulting in a warning later (on Alpine 3.10):
-- Found Iconv
-- Looking for pthread.h
CMake Warning (dev) at /usr/share/cmake/Modules/CheckIncludeFile.cmake:80 (message):
Policy CMP0075 is not set: Include file check macros honor
CMAKE_REQUIRED_LIBRARIES. Run "cmake --help-policy CMP0075" for policy
details. Use the cmake_policy command to set the policy and suppress this
warning.
CMAKE_REQUIRED_LIBRARIES is set to:
/usr/lib/libintl.so
For compatibility with CMake 3.11 and below this check is ignoring it.
Call Stack (most recent call first):
/usr/share/cmake/Modules/FindThreads.cmake:105 (CHECK_INCLUDE_FILE)
CMakeLists.txt:482 (find_package)
This warning is for project developers. Use -Wno-dev to suppress it.
-- Looking for pthread.h - found
* build: remove lists / REMOVE_ITEM around check_c_source_compiles
If check_c_source_compiles() succeeded (HAVE_WORKING_LIBINTL is set)
then the result of find_xxx() doesn't matter. This happens on systems
(linux+glibc) where libintl is available passively.
This allows `find_package(LibIntl REQUIRED)` to work and will still
correctly fail (REQUIRED) on systems lacking libintl.
On some systems, such as NetBSD, the gettext header is tucked under the
gettext directory in the system include area. Let's add a path suffix
to ensure we correctly discover the header on such systems.
- Defined CMake checks for all headers in config.h.in
- Removed headers checks that are not used anymore:
sgtty.h sys/statfs.h libintl.h poll.h
- Added UNIX check
- Add some fatal checks
+ Check for setenv() and fail if it does not exist
since our os layer just assumes it does
+ lstat is required by os_unix.c
+ sys/wait.h is required in UNIX
- Removed entries for functions that are not being used: getcwd,
getrlimit, getwd, nanosleep, sigaltstack, getwd, sigstack, fseeko
- Replaced nearly all defines in config.h.in for functions with
compile time checks
- Add check for symbol FD_CLOEXEC
- Add check for langinfo CODESET
- HAVE_ICONV_H and HAVE_ICONV hold the expected checks but Neovim uses
USE_ICONV define to actually decide whether to enable it
- Removed checks that are no longer needed
+ USEMEMMOVE
+ _FILE_OFFSET_BITS
+ HAVE_ST_BLKSIZE
+ dlfcn.h
