Looks similar to Kali Linux - Install Fail #42

[dirtygardner]

SOLVED with help from Kali Linux - Install Fail #42 but installing as ROOT worked, installing as USER yielded: "PermissionError: [Errno 13] Permission denied: '/usr/local/share/scrcpy/scrcpy-server.jar'
FAILED: install"

AS USER:

git clone https://github.com/Genymobile/scrcpy
cd scrcpy
wget https://github.com/Genymobile/scrcpy/releases/download/v1.5-fixversion/scrcpy-server-v1.5.jar
meson x --buildtype release --strip -Db_lto=true \
    -Dprebuilt_server=/path/to/scrcpy-server.jar

AS ROOT (in same directory as above):

cd x
ninja
ninja install

[rom1v]

You need to ninja as user and ninja install as root.

See 4c49b27 and #42 (comment).

[dirtygardner]

Directions at https://github.com/Genymobile/scrcpy should be edited to reflect this point.

[rom1v]

@dirtygardner The instructions in BUILD use ninja and sudo ninja install to explicit that ninja install must be run as root.

I added an explicit note: b2c3df7.

[dirtygardner]

Some environments don't use sudo. Thanks for adding the explicit note!
