Hi, @H1-N1

What's your operating system?

Thanks.

Many people are annoyed on Windows with this problem.

The cause is that it looks for scrcpy-server.jar in the current directory (.), not the same directory as scrcpy.exe: https://github.com/Genymobile/scrcpy/issues/278#issuecomment-429330345

We should change that for Windows: if SCRCPY_SERVER_PATH is not set, then we need to use the directory of scrcpy, then append scrcpy-server.jar. Ref: https://stackoverflow.com/questions/2647429/c-windows-path-to-the-folder-where-the-executable-is-located/2647446#2647446

@rom1v or just add args that take care of server path
Becose i allready set SCRCPY_SERVER_PATH but I get the same error
Thanks for you replay guys

@H1-N1 What did you do exactly?

Here is how it works.

If you launch scrcpy from its own directory (either by typing scrcpy from that directory in a terminal, or by double-clicking on scrcpy.exe from your file browser), it should work as is (unless you set SCRCPY_SERVER_PATH to a wrong value). To make it work, just unset that environment variable, and retry (start a new terminal after you unset it).

If instead you added the scrcpy directory in your PATH, and try to launch scrcpy from another directory, then you need to set SCRCPY_SERVER_PATH to the full path of the jar file (e.g. C:\Users\h1n1\scrcpy\scrcpy-server.jar).

@rom1v
im lunching scrcpy from a process with administrator privileges
this is way he well not see service.jar this is why i sugest to add a agrs to scrcpy newer version
set path well not resolve the problem at all...

[rom1v]

From which directory do you start scrcpy? (which is your current directory and what command do you enter?)

What is the exact value assigned to your SCRCPY_SERVER_PATH? Is it defined for your system (not only your user)?

[karottenbaum]

I also get this error on Ubuntu, where scrcpy looks in /usr/local/bin/scrcpy-server.jar (scrcpy's install directory) instead of /usr/local/share/scrcpy/scrcpy-server.jar.

@karottenbaum If you git clone/git pull this morning, please update to current master.

There was an issue: https://github.com/Genymobile/scrcpy/commit/53310a925a495f61d42dd90faa0a0748074d63c5.

[karottenbaum]

Thanks, it's working with that commit. Sorry for the trouble!

@rom1v using the official v1.9 tag, both if manually passing -Dportable=false or applying the fix in 53310a9 I still get a failure during build with the following message.

I'm a bit rusty with C, but from what I remember, using #define to declare a macro, accepts only 1 parameter, so server.c at lines 18 and 19 look wrong to me:

#define DEFAULT_SERVER_PATH PREFIX "/share/scrcpy/" SERVER_FLENAME
#define DEVICE_SERVER_PATH "/data/local/tmp/" SERVER_FILENAME

and the ninja build fails due to this. Am I missing something?

[rom1v]

@hrk You also need the commit before: bcd0a876f7bf52642330410812a6b7100cdeda91.

In C, you can concatenate string literals by just writing them one after the other:

const char *s = "hello" " world" "!";

This is what the macro does.

Wow, didn't know about that. And didn't notice the spelling mistake. :) Thank you, it's working now.

[rom1v]

v1.9 fixes the problem by searching in the same directory as the binary on Windows, so I'm closing.
