Meson always returns -pthread in dependency('threads') on non-MSVC
compilers. On Windows we use Windows threading primitives, so we don't
need this. Avoid adding -pthread to libzstd's link flags, either as a
Meson subproject or via pkg-config Libs.private, so the application
doesn't inadvertently depend on winpthreads.
Add a Meson MinGW cross-compile CI test that checks for this. It turns
out that pzstd fails to build in that environment, so have the test
skip building contrib for now.
We need to run it for the tests, even if programs are disabled. So if
they are disabled, create a build rule for the program, but don't
install it. Just make it available for the test itself.
In commit 031de3c69c a feature of Meson
0.50.0 was added, but the minimum specified version of Meson is 0.48.0.
Meson therefore emitted a warning:
WARNING: Project targets '>=0.48.0' but uses feature introduced in '0.50.0': required arg in compiler.has_header.
And if anyone actually used Meson 0.48.0 to build with, it would error
out with mysterious claims that the build file itself is invalid, rather
than telling the user to install a newer version of Meson.
Solve this by bumping the minimum version to align with reality. This
e.g. drops support for Debian oldstable (buster)'s packaged version of
Meson, but still works if backports are enabled, or if the user can
`pip install` a newer version.
It uses non-portable compiler options unconditionally. Elsewhere, we
check the compiler ID and only add the right ones, globally. Do the same
here.
NDEBUG can actually be handled by a core option, so while we are moving
things around, do so.
Unfortunately, this doesn't fix things entirely. The remaining issue is
not Meson's issue though -- MSVC simply does not like this source code
and somehow chokes on innocent code with the inscrutable "syntax error"
and "illegal token".
Run the scraper command to establish the project version immediately,
rather than wait for the build to be configured. This simplifies the
code and ensures that project introspection works correctly.
libm is not guaranteed to exist. POSIX requires the math functions to
exist, but doesn't require to have it be a standalone library.
On platforms where libm exists as a standalone library, it will always
be found by meson -- it is shipped with libc.
If it is not found, then we can safely assume the linker will make the
math functions available by default.

Fixes building with bin_tests=true on Windows.
This matches the Makefile build. Due to one private xxhash symbol in use
by the program, it recompiles a private copy of xxhash.
Due to the test binaries making extensive (?) use of private symbols, it
doesn't even attempt to link to shared libzstd, and instead, all of the
original object files are added to libtestcommon itself for private
linkage. This, too, matches the Makefile build.
Ref. #2261
meson prefers that project-level options for Wall/Wextra/pedantic be
used, rather than hardcoding raw flags in add_project_arguments. If you
do the latter anyway, it raises a meson warning.
Set the default options for the project to use all this.
Also move the -Werror comment to the project default options with
appropriate format, but leave it commented out since it does not work.
* tests: Fix shellcheck warnings in playTests.sh
* tests: Do not use ../programs which is relative to tests dirs
This commit fixes error when running playTests.sh in Meson.
Mesonbuild runs out of tree, so ./datagen not in `zstd/tests` dir,
it lies in <mesonbuilddir>/tests. This leads to ../programs invalid.
* tests: Replace relative paths for zstd/tests dir
* playTests: Set shell options explicitly, not in shebang
* playTests: Replace echo -e with printf
* meson: Fix test-zstd
Use std=gnu99 to build and test just like `make test`.
* meson: Fix legacy test
* meson: Enable testing in CI
Run build under release mode for faster test time.
* meson: Increase timeout time for test-zstream
