anotherInstanceStarted not working on Linux

[Kroko]

anotherInstanceStarted is not working on Linux. It seems that Linux implementation is not calling deliverBroadcastMessage and sendActionMessage.

Can this be fixed?

is there a technical reason why this is not implemented for nixes? would it need to require DBUS? - can anyone give some advice on how to get it working?

I implemented this with namedpipes.

But I needed to fix Linux NamedPipe implementation first.

NmedPipe read(...) problems in Linux

I’m using NamedPipe in Windows and in Linux application. Windows version works fine, Linux version does not. I compared native implementation in juce_win_Files.cpp and juce_posix_NamedPipe.cpp files. Windows version returns if ReadFile reads anything, Linux version does not and tries to read whole buffer. Because of this different behavior I believe Linux implementation is not correct. Here is my Linux implementation that works same way as Windows does: (juce_posix_NamedPipe.cpp) int read (…

Hey folks, reviving this thread because it’s still an issue for us… Any plans to fix anotherInstanceStarted for Linux?

I would use this if it were implemented!

I needed it on windows as well and had to implement it myself Windows vs Mac command line handling differs · Issue #607 · juce-framework/JUCE · GitHub i wonder if it has ever been implemented on android and ios too

It has been implemented 3 years ago but superficially ignored
