ddserver file not build after compile

[Anco-60]

Hallo all together!

I installed an actual qDSLR on a Raspi 3 with Stretch and qDSLR is running and does function. Also LibUSB is installed without issues and ddserver Source package is cloned to the pi via "clone https:// properly, without issues too.

When running the compile command from out of the "DslrDashboardServer" folder with and without "sudo" with the standard bash code:

"g++ -Wall src/main.cpp src/communicator.cpp pkg-config --libs --cflags libusb-1.0 -lpthread -lrt -lstdc++ -o ddserver"

I get lots of warnings, but also several error messages! There is no "ddserver" file created at the end and for that reason also the following command: "chmod +x ddserver" does not work.

Is there any help possible?!

Best Regards

See:

pi@acd:/package/DslrDashboardServer $ chmod +x ddserver chmod: cannot access 'ddserver': No such file or directory

Switched to new operting system to fix it.
