This is my error:

Description Resource Path Location Type
cannot find -l/usr/lib/x86_64-linux-gnu/libusb-1.0.so lsusb C/C++ Problem

I have verified that the library does indeed exist at that specific location. Further the command:

g++ lsusb.c -o lsusb -L/usr/lib/x86_64-linux-gnu/ -lusb-1.0

works perfectly fine! What needs to be done with the Eclipse environment?

Thank You! Smile

Quote:

-l/usr/lib/x86_64-linux-gnu/libusb-1.0.so

This will not work. The option "-L" specifies the library search path and "-l" specifies the library. You have to omit the prefix "lib" and the suffix ".so" (see your own command).
