I am trying to start *PulseView* and *sigrok* AppImages. Unfortunately, I am getting an error message and I cannot figure out how to fix it:
./sigrok-cli-0.7.1-x86_64.AppImage sigrok-cli: symbol lookup error: /tmp/.mount_sigrokLM29y6/usr/lib/libsigrok.so.4: undefined symbol: libusb_get_version ./PulseView-0.4.1-x86_64.AppImage pulseview: symbol lookup error: /tmp/.mount_PulseVunpXcp/usr/lib/libsigrok.so.4: undefined symbol: libusb_get_version Then, I tried to build from source following the instructions at https://sigrok.org/wiki/Linux . I have built successfully all libraries but got the same undefined reference to *libusb* when building *sigrok-cli*: ~/temp/sigrok-cli$ make make all-am CCLD sigrok-cli /usr/local/lib/libsigrok.so: undefined reference to `libusb_free_pollfds' /usr/local/lib/libsigrok.so: undefined reference to `libusb_get_version' /usr/local/lib/libsigrok.so: undefined reference to `libusb_handle_events_timeout_completed' /usr/local/lib/libsigrok.so: undefined reference to `libusb_has_capability' /usr/local/lib/libsigrok.so: undefined reference to `libusb_error_name' /usr/local/lib/libsigrok.so: undefined reference to `libusb_get_port_numbers' collect2: error: ld returned 1 exit status Makefile:476: recipe for target 'sigrok-cli' failed make[1]: *** [sigrok-cli] Error 1 Makefile:362: recipe for target 'all' failed make: *** [all] Error 2 Here are some dumps: $ lsb_release -a LSB Version: core-9.20160110ubuntu0.2-amd64:core-9.20160110ubuntu0.2-noarch:security-9.20160110ubuntu0.2-amd64:security-9.20160110ubuntu0.2-noarch Distributor ID: Ubuntu Description: Ubuntu 16.04.6 LTS Release: 16.04 Codename: xenial $ apt-cache policy libusb-1.0* libusb-1.0-0: Installed: 2:1.0.20-1 Candidate: 2:1.0.20-1 Version table: *** 2:1.0.20-1 500 500 http://de.archive.ubuntu.com/ubuntu xenial/main amd64 Packages 100 /var/lib/dpkg/status libusb-1.0-0-dbg: Installed: (none) Candidate: 2:1.0.20-1 Version table: 2:1.0.20-1 500 500 http://de.archive.ubuntu.com/ubuntu xenial/main amd64 Packages libusb-1.0-0-dev: Installed: 2:1.0.20-1 Candidate: 2:1.0.20-1 Version table: *** 2:1.0.20-1 500 500 http://de.archive.ubuntu.com/ubuntu xenial/main amd64 Packages 100 /var/lib/dpkg/status libusb-1.0-doc: Installed: 2:1.0.20-1 Candidate: 2:1.0.20-1 Version table: *** 2:1.0.20-1 500 500 http://de.archive.ubuntu.com/ubuntu xenial/main amd64 Packages 500 http://de.archive.ubuntu.com/ubuntu xenial/main i386 Packages 100 /var/lib/dpkg/status Do you have ideas what is the problem?
