Scrcpy: meson : command not found

Did you install the packages as explained?

[Keneil-Thompson]

yes

[Keneil-Thompson]

i see the installed packages in the folder C:\msys32\mingw32\bin

[rom1v]

Do you run mingw32.exe (not msys2.exe)?

[Keneil-Thompson]

yes

[SergioVJr]

Got the same problem but for 64-bit, tried with both msys2.exe and mingw64.exe (after reading this). It was a fresh installation too, just for this.

[rom1v]

What is the result of:

pacman -S mingw-w64-x86_64-meson

or:

pacman -S mingw-w64-i686-meson

?

[rom1v]

And:

echo $PATH

[rom1v]

@doublejumper @Kaiju-A Your PATH variables seems to be correct, meson should be in /mingw64/bin (or /mingw32/bin):

$ which meson
/mingw64/bin/meson

That's weird.

[Keneil-Thompson]

ADMIN@Adeidrick-EXT MINGW32 ~
$ /mingw32/bin
bash: /mingw32/bin: Is a directory

yup

[rom1v]

@Kaiju-A

ls -l /mingw32/bin/meson

[Keneil-Thompson]

$ ls -l /mingw32/bin/meson
ls: cannot access '/mingw32/bin/meson': No such file or directory

[rom1v]

OK, that's the problem. So where is the binary meson installed from your package?

find / -name meson

(brute force)

[Keneil-Thompson]

$ find / -name meson
/mingw32/share/licenses/meson
/mingw64/share/licenses/meson
find: failed to read file names from file system at or below ‘/’: No such file or directory

[Keneil-Thompson]

what should i do ? is it possible to build on a different pc"B", then use on pc "A"?

[rom1v]

@Kaiju-A You want to build it by yourself on windows because you need a 32 bits version, or you want a version more recent than the last release?

[Keneil-Thompson]

ADMIN@Adeidrick-EXT MINGW32 ~
$ mkdir x
mkdir: cannot create directory ‘x’: File exists

ADMIN@Adeidrick-EXT MINGW32 ~
$ meson x --buildtype release --strip -Db_lto=true
bash: meson: command not found

tried this, didnt work

[SergioVJr]

Got the same results. And I just want a more recent version.

[atrich]

HI - I recently set up a build to make a pull request. On my windows machine, I had to add the ".py" file extension when running meson. Eg:

$ meson.py x --buildtype release --strip -Db_lto=true

[rom1v]

@Kaiju-A @doublejumper Does calling meson.py work for you?

[Keneil-Thompson]

yes.
another problem arose
$ meson.py x --buildtype release --strip -Db_lto=true
Error during basic setup:

Neither directory contains a build file meson.build.

[rom1v]

yes.

:+1:

You need to execute this command from the _scrcpy_ root project directory.

[Keneil-Thompson]

how exactly

[rom1v]

how exactly

git clone https://github.com/Genymobile/scrcpy
cd scrcpy

https://github.com/genymobile/scrcpy#common-steps

[Keneil-Thompson]

is this it

[SergioVJr]

I've solved my issue.
Running meson.py solved it initially. Then it said there was no file "x", so i created the directory. But then it said i had v35.something, when the project required >=37. So i ran pacman -Syu to synchronise the pacman database (because it said v35 was latest) and updated meson to v44 along with some dependencies. Then tried running again and it didn't find meson.py, so i switched back to just meson and i can progress now.
TL;DR: sync pacman databases and update meson before trying to run it

[Keneil-Thompson]

feel like i have done something wrong

$ meson x --buildtype release --strip -Db_lto=true

[Keneil-Thompson]

keep on getting this error, reinstalled the packages , still the same thing

[tAzO8596]

Even I encounter this error and can't resolve but if ninja command completes successfully you can run ninja install & scrcpy command.

[nabeelmoeen]

I was getting this error when i incorrectly installed the x86 (32-bit) libraries in 64 bit MSYS2
reinstalling the correct version to the MSYS2 you are running (on windows it you have both options) resolved the issue

[nabeelmoeen]

ninja run

throws an error

[0/1] Running external command run.
Could not execute command "scripts/run-scrcpy.sh": [WinError 193] %1 is not a valid Win32 application
FAILED: meson-run

and when i copy the compiled scrcpy.exe from /app subfolder to my directory with adb and other required dlls, running it does not bring anything on screen.

EDIT: btw, I'm trying to build the 'dev' branch
EDIT 2: it appears the fresh build is referencing newer libraries vs. the ones in the folder, e.g. avformat-58.dll (vs avformat-57.dll in the folder)
EDIT 3: downloaded the missing libraries, and had to rename the file to scrcpy.exe (had copied it as scrcpy2.exe) .... now its working !!

[gzliuqingyun]

ninja run got the same error as @Kaiju-A .
but ninja install successful, and I just run scrcpy.exe directly worked. (On Windows)
