The `-Wl,-z,noexecstack` and `-Wa,--noexecstack` flags are already set for CMake, but not for Meson. This brings the flags to the Meson build as well. Note that this maintains the discrepancy in behavior between CMake and Meson when it comes to enabling ASM: on CMake, the ZSTD_HAS_NOEXECSTACK variable is set and these flags added for GCC/Clang and MinGW. Then later, the ZSTD_HAS_NOEXECSTACK variable is checked (along with some other conditions) to enable or disable ASM. However on Meson, this logic is restricted to simply checking for GCC/Clang. This patch maintains this behavior; noexecstack is dependent on GCC/Clang only.
Meson build system for zstandard
Meson is a build system designed to optimize programmer productivity. It aims to do this by providing simple, out-of-the-box support for modern software development tools and practices, such as unit tests, coverage reports, Valgrind, CCache and the like.
This Meson build system is provided with no guarantee and maintained by Dima Krasner <dima@dimakrasner.com>.
It outputs one libzstd, either shared or static, depending on
default_library option.
How to build
cd to this meson directory (build/meson)
meson setup -Dbin_programs=true -Dbin_contrib=true builddir
cd builddir
ninja # to build
ninja install # to install
You might want to install it in staging directory:
DESTDIR=./staging ninja install
To configure build options, use:
meson configure
See man meson(1).
