Compilation hid-query.c: errors

[fjk8]

Im trying to compile TEMPered on Raspberry Pi. First i have some warrnigs on hidapi compilation:

~/hidapi/linux $ make VERBOSE=1 g++ -Wall -g -fpic -c -I../hidapi pkg-config libusb-1.0 --cflags ../hidtest/hidtest.cpp -o ../hidtest/hidtest.o g++ -Wall -g hid.o ../hidtest/hidtest.o pkg-config libudev --libs -o hidtest-hidraw cc -Wall -g -fpic -c -I../hidapi pkg-config libusb-1.0 --cflags hid-libusb.c -o hid-libusb.o hid-libusb.c: In function ‘hid_open_path’: hid-libusb.c:752:10: warning: variable ‘num_devs’ set but not used [-Wunused-but-set-variable] g++ -Wall -g hid-libusb.o ../hidtest/hidtest.o pkg-config libusb-1.0 --libs -o hidtest-libusb cc -Wall -g pkg-config libusb-1.0 --libs -shared -fpic -Wl,-soname,libhidapi-libusb.so.0 -o libhidapi-libusb.so cc -Wall -g pkg-config libudev --libs -shared -fpic -Wl,-soname,libhidapi-hidraw.so.0 -o libhidapi-hidraw.so

~/TEMPered/temp $ cmake ../ -- The C compiler identification is GNU 4.6.3 -- Check for working C compiler: /usr/bin/gcc -- Check for working C compiler: /usr/bin/gcc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Configuring done -- Generating done -- Build files have been written to: /home/fjk/TEMPered/temp

cmake is sucessful

And error 2.

I worked around this by recompiling libhidapi-hidraw.so with:

cd hidapi/linux && cc -Wall -g pkg-config libudev --libs -shared -fpic -Wl,-soname,libhidapi-hidraw.so.0 hid.0 -o libhidapi-hidraw.so

Note the added hid.o.

I guess it is a bug in hidapi.
