Build errors using meson

[nbommersbach]

Hello,
I had problems building pistache from source as meson could not find openssl. I solved this by tweaking around with the openssl visibility settings and finally could make it visible to pkg-config. I was then able to successfully generate the build folder using:

meson setup build \ --buildtype=release \ -DPISTACHE_USE_SSL=true \ -DPISTACHE_BUILD_EXAMPLES=true \ -DPISTACHE_BUILD_TESTS=true \ -DPISTACHE_BUILD_DOCS=false \ --prefix=$PWD/prefix

Running the next step from that README (meson compile -C build) left me with countless errors I cannot identify and solve:

This goes on for quite a while. Does someone know what I can do? I am out of ideas.

What platform are you using?

[nbommersbach]

Sorry. I'm running macOS BigSur 11.5.2. standard compiler is Clang 12.0.0 apple darwin

[Tachi107]

Pistache currently uses Linux-specific APIs to do networking, so it can't be complied on macOS.

This is stated on the pistache.io website, but not in the Readme. I'll update it since a lot of people never visited the site. Sorry for the inconvenience!

No problem and thanks for the answer!
