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.
`xlocale.h` is not available on Linux, so we can't just universally
include it.
`HAVE_XLOCALE_H` was already being tested/set in the CMake script as a
possible requirement for `wcstod_l` support, this just adds it to
`config_cmake_h.in` and uses it in `wutil.h` to gate the include.
Removes the dependency on the current user's home directory, instead
overriding it to be within the current hierarchy.
Fixes the tests on Debian buildd, where the home directory is
deliberately unwriteable to pick up errors in builds.
The one thing I was missing:
`echo -n` isn't POSIX. In practice, it appears the only shell to encounter this
is macOS' crusty old bash in sh-mode. Just replace it with `touch`.
This reverts commit fc5e8f9fec.
This makes the script worse, but it's good enough.
The required changes are:
- `shopt -s nullglob`, which we simply don't use (we have one glob, but that's
guaranteed to match because we ship the files)
- One array, which we replace with a direct use of the glob (plus it
used `echo` again?)
- The `function` word, which I'm still annoyed is even a thing!
- Variable indirection (`color=${!color_var}` - instead we pass the
value directly - which makes the script uglier!)
- One array, which we replace with a function
- A use of `type -t`, replaced with `command -v`
- A use of `${var:begin:end}` substring expansion, replaced with trickery.
- `set -o pipefail` is replaced with a function
Note that checkbashisms still complains about `command -v`, because
we're not using it with "-p". But we _want_ to check the current
$PATH, and `command -v` is POSIX.
This still uses `local`, which technically isn't in POSIX.
The tests now appear to pass in:
- bash
- dash
- zsh
- mksh
- busybox
Starting with Fedora 30 and RHEL 8, ambiguous python shebangs will now
throw errors during the RPM build process instead of just warnings,
since these systems have moved to Python 3 by default, and Python 2 may
not be available in the future.
See [this
page](https://fedoraproject.org/wiki/Changes/Make_ambiguous_python_shebangs_error)
for more details.
Drop these shebangs as the scripts are only ever called from fish
wrappers.
Rather than killing the process with close, read EOF after sending the
"exit" command and wait for OS cleanup (per the expect examples).
Not cleaning up with wait caused expect to crash on all 32-bit platforms
including i586 and armv7l with "alloc: invalid block: 0xbf993ccb: 3d 3b".
64-bit platforms were not affected, for reasons that are not clear.
CentOS 7 does not have rhel_version as one of its macros, so trying to
build results in CMake errors, since we get `cmake` instead of
`cmake3`. These additional conditions allow the spec to build
successfully on CentOS 7.
Using %rhel should allow one set of conditionals to work across CentOS 7
and RHEL 7.
This has been tested on both.
