When I do lsusb I have:
Bus 001 Device 004: ID 1a86:7523 QinHeng Electronics

So I went into 51-gqgmc.rules and Changed both of the ATTR{idWendor} to 1a86 and single the ATTRS{idProduct} to 7523.

I think the problem starts in step 5 when I try to make all gqgmc in the root directory and get these errors:

(.text+0x18): undefined reference to main'
(.text+0x1c): undefined reference to main'
collect2: error" ld returned 1 exit status
<builtin>: recipe for target "gqgmc" failed
make: *** [gqgmc] error 1</builtin>

Hi,

Trying to get this to log with my Raspberry Pi 4 8gb with Ubuntu Mate 18.04 running.

Running into problems at step 6a. sudo cp ./51-gqgmc.rules /etc/udev/rules.d/51-gqgmc.rules.

When running that from my root directory I get the error:

cp: failed to access '/etc/udev/roles.d/51-gqgmc.rules': not a directory

So then i just copied it to /etc/udev/roles.d and it worked. And then I reloaded it.

But then when checking if /dev/gqgmc exists it says. ls:cannot access '/dev/gqgmc': No such file or directory.

Do you have any idea on what im doing wrong? Thanks!

Hello Phil, i'd like use this package on Raspberry with "Raspbian GNU/Linux 9 (stretch)". When i try to compile it (make all) i see this message

root@raspberrypi:/home/pi/gqgmc# make all
rm -f /home/pi/gqgmc/moc.cc

Patterns.mk:9: recipe for target '/home/pi/gqgmc/obj/gqgmc.o' failed
make: *** [/home/pi/gqgmc/obj/gqgmc.o] Error 1

Can you help Me?
Thanks in advance Luigi

 GQGMC is a user level driver for interfacing a Linux host to GQ Electronic's GMC-3xx (e.g., GMC-300) geiger-muller counter. Written in C++, the driver provides an interface method for each of the capabilities of the GMC-3xx. The capabilities of the GMC-3xx are described in the GQ-GMC-ICD.odt (or doc) document. Perhaps of greatest use, the GMC-3xx can provide the Counts per Minute upon command from the Linux host. The GMC-3xx also has configuration data and an internal history buffer all of which are read/write-able from the Linux host. Further documentation is embedded in the source software, principally, gqgmc.hh and gqgmc.cc. Any user is expected to read the documentation embedded in the source code files which has complete discussions of the GMC-300's data and operation, in other words, the documentation and the code are integrated.

-A sample console based program is provided for excercising the GMC-3xx. A sample Qt based GUI program is also provided, although it functions only as a simple data logging plot of the counts per minute. A Makefile is also provided for building the console or GUI programs. The sample programs are only compiled for 64-bit x86 Linux under Ubuntu 11.10, 12.04, and 14.04, however, it is compilable for 32-bit Linux. See the README.txt file for changes needed to compile/link for 32-bit Linux.
