The compiler flag `-Werror=unguarded_availability` was hard-coded for
macOS, but is not supported by GCC on macOS 10.10 (Yosemite). Test for
support with CHECK_CXX_COMPILER_FLAG before forcing it.
This was broken in a8eb02f9f5 when the
detection was corrected for FreeBSD. This patch makes the detection work
for both Linux and FreeBSD instead of one or the other (tested).
CMake seems to have trouble finding libraries from multiarch packages
that do not have the compatibility symlink installed to the
arch-independent library directory. Users must either manually supply
the path to the library in question via command-line parameters or we
can fall back to CMake's alternate method of finding packages based off
of pkg-config rather than using the hard-coded `FindCurses` CMake module
specific to the CMake version/distribution installed.
Just sets locale to "C" (because that's the only one we need), does
wcstod and resets the locale.
No idea why uselocale(loc) failed for me, but it did.
Fixes#5407.
This fixes a variety of issues related to building the documentation
with CMake. In particular it cleans up the dependency management and
fixes some issues where the documentation build was using generated
files from the source directory.
fish's cmake install routines were attempting to create system
directories that already existed, an operation for which the permissions
to do so may not be available (e.g. /usr/local/share/pkgconfig)
This commit first checks if a directory exists before creating it.
Homebrew and other systems set the path for the extra completion,
function and configuration directories outside the writeable prefix.
Mirror the autotools build in trying to create these directories, but
not causing the whole install to fail if this operation in unsuccessful.
The custom command for fish.pc had a dependency on FBVF, but it appears
that the relative path to FBVF was incorrect and with CMake 3.10.1 under
FreeBSD this was consistently causing the build to fail if
../build_tools/git_version_gen.sh hadn't (coincidentally, I think?)
already run.
Explicitly set the dependency path for FBVF to the binary directory.
The custom command for fish.pc had a dependency on FBVF, but there was
no cmake rule for the generation of the FBVF file. With CMake 3.10.1
under FreeBSD, this was consistently causing the build to fail if
../build_tools/git_version_gen.sh hadn't (coincidentally, I think?)
already run.
The non-ncurses version of term.h requires that curses.h be first
included. Only very recent versions of CMake include a LANGUAGE
option to CHECK_INCLUDE_FILES, so we aren't using it and specifying
CXX here..
CheckFunctionExists checks for C linkage only, and recommends the use of
CheckSymbolExists in the documentation. This improves the detection of
C++ features, as opposed to C features.
`-v` is a non-standard GNU-only extension to `awk`, its usage in the
generation of the fish.pc script breaks on non-GNU platforms (such as
FreeBSD and presumably macOS).
Using `sed` with only standard posix commands instead.
