[SOLVED] can't define env var without value in user environment.d

jronald · 2025-02-23 07:16:18

$ cat ~/.config/environment.d/cmake.conf
CMAKE_BUILD_PARALLEL_LEVEL=

$ sudo reboot
$ env | grep CMAKE
# nothing

while with a value, it works:

$ cat ~/.config/environment.d/cmake.conf
CMAKE_BUILD_PARALLEL_LEVEL=8

$ sudo reboot
$ env | grep CMAKE
CMAKE_BUILD_PARALLEL_LEVEL=8

Did you try actually setting an empty string?

CMAKE_BUILD_PARALLEL_LEVEL=""

"CMAKE_BUILD_PARALLEL_LEVEL=" would also unset that variable in most shells (bash etc)

The only shell I know removing var with "VAR=" is windows cmd (set VAR=).
In zsh and bash I do "unset VAR", VAR= just set it to empty string (but does not remove it).

True indeed. I've too much custom stuff around

The syntax only accepts "foo=bar".
If an empty "bar" is treated as "foo=" and that is ignored, you'll have to export CMAKE_BUILD_PARALLEL_LEVEL= from etc/profile.

It works, thanks.

/etc/profile.d/cmake.sh

export CMAKE_BUILD_PARALLEL_LEVEL=
