I just did a brew upgrade scrcpy to install v1.13 and it’s working!

I’m trying to build the dev branch but getting this error:

same when I build the release version of the main branch:

[edit] uninstalling JDK14 and installing JDK8 in the hopes that building will work…and I’m getting further:

ugh, still erroring out in debug mode with adb push

should I get gdb running instead of lldb?

But I don’t understand why you get ERROR: "adb push" exited unexpectedly only while debugging.

I am running Catalina on (technically) unsupported Mac. See the message about Failed to obtain Metal device? That might be the clue. Something in the toolchain you’re using is not compatible with my patched Catalina install 😦

ERROR: "adb push" exited unexpectedly

Before debugging, it must at least work “normally”:

d/app/scrcpy

(without lldb)

scrcpy % lldb d/app/scrcpy

(lldb) bt
error: invalid thread
(lldb) 

in the ~gdb~ lldb prompt, type r then Enter.

When it crashes, type bt then Enter.

justs sits there not crashing:

scrcpy % lldb d/app/scrcpy 
(lldb) target create "d/app/scrcpy"
Current executable set to 'd/app/scrcpy' (x86_64).
(lldb) 

lldb instead of gdb?

I got so close:

scrcpy % gdb d/app/scrcpy
zsh: command not found: gdb

I need to manually kill or else I get a could not listen error.

Use the dev branch instead of master, it will try another port automatically.

Illegal instruction: 4

OK, great, so you reproduce with your own build 👍

Now, build in debug mode and run with gdb:

meson d -Dprebuilt_server=/Users/[edit]/scrcpy/server-prebuilt/scrcpy-server-v1.12.1
ninja -Cd
export SCRCPY_SERVER_PATH=d/server/scrcpy-server
gdb d/app/scrcpy

In the gdb prompt, type r then Enter.

When it crashes, type bt then Enter.

everytime it aborts it leaves a copy s̶c̶r̶c̶p̶y̶ adb running which I need to manually kill or else I get a could not listen error. Anyway, after doing that:

scrcpy % ./run x                            
2020-03-23 13:04:10.014 scrcpy[4081:85814] INFO: scrcpy 1.12.1 <https://github.com/Genymobile/scrcpy>

./run: line 23:  4081 Illegal instruction: 4  SCRCPY_SERVER_PATH="$BUILDDIR/server/scrcpy-server" "$BUILDDIR/app/scrcpy" "$@"

Once you meson x …, you must build with ninja -Cx.

Then, to run, execute:

./run x

meson configure x didn’t work but rm -rf x did but I’m still getting:

scrcpy % scrcpy
2020-03-23 12:55:57.701 scrcpy[4002:81574] INFO: scrcpy 1.12.1 <https://github.com/Genymobile/scrcpy>

zsh: illegal hardware instruction  scrcpy

how do I know I’m using the compiled version as opposed to the brew version?

[edit] I guess because it’s running server out of …/share/… instead of …/Cellar/…?

Directory already configured.

Your meson command did nothing, because x already existed.

Either use meson configure x … or just rm -rf x and retry.

I am in way over my head:

scrcpy % meson x --buildtype release --strip -Db_lto=true \
    -Dprebuilt_server=/Users/[edit]/scrcpy/server-prebuilt/scrcpy-server-v1.12.1
Directory already configured.

results in:

No Java runtime present, requesting install.
FAILED: server/scrcpy-server

now I’m trying to figure out how to install JDK…

do I need to build the server? [edit] and to install Android SDK

No: https://github.com/Genymobile/scrcpy/blob/master/BUILD.md#prebuilt-server

do I need to build the server? [edit] and to install Android SDK, do I need to download and install the whole Android IDE?

[edit2] this problem seems to be related to Catalina as I had run older versions of scrcpy on this same iMac when it was running High Sierra.

Anyway, I’m trying to build it and the server now.

Unless you trigger some undefined behavior 😕

If you can build it in debug and reproduce, I’m interested.

It seems the binary you’re running uses CPU instructions not supported by your CPU 😕

It should work if you build it from your computer directly: https://github.com/Genymobile/scrcpy/blob/master/BUILD.md
