installation issue

[devnexen]

I suspect since it s possible to also install scxtop, I always get this issue at first install attempt

meson install -C build
ninja: Entering directory `/home/dcarlier/Contribs/scx/build'

ERROR: Unhandled python OSError. This is probably not a Meson bug, but an issue with your build environment.

I might be doing something wrong but the 2nd time it always works so nothing major.

Hi @devnexen

Looks like you don't have permissions to create /usr/local/include/scx directory.

I get the following prompt when trying the same (and after a timeout the above error message):

Installing subdir /home/frelon/src/scx/scheds/include/scx to /usr/local/include/scx
Installation failed due to insufficient permissions.

If you want to install to another directory there is also the --destdir flag:

meson install -C build --destdir $(pwd)/install

Eventually, it works when I try a second time without me changing the permissions manually. Thinking of this ticket, it happens less often now, seems a bit random.

Weird! What distribution are you building on?

debian unstable. I do not know meson as much as cmake, so no idea if this is a meson version bug or this project issue. But again, no big deal :)
