Cannot build on Ubuntu: libusb linking problem
Background info
$ lsb_release --description --codename
Description: Ubuntu 19.04
Codename: disco
$ uname -a
Linux ruatha 5.0.0-27-generic #28-Ubuntu SMP Tue Aug 20 19:53:07 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
I have cloned this and the submodule to my Ubuntu system. I had build essentials, but I had to install a few extra dependencies...
sudo apt install libusb-1.0-0-dev
sudo apt install qt5-default
sudo apt install libqt5svg5-dev
However, now when I try to build, I get the following... (this is after it fails once, so the successful compilation/linking doesn't show up)

I've tried troubleshooting, but I'm not a dev. Googling for the ld errors brings up some options, but I tried all the items I found and none worked.
@KlfJoat try adding -lusb-1.0 to call in libcmmk Makefile so the line looks like:
${CC} -shared ${CFLAGS} $^ -o out/[email protected] -lusb-1.0
@JanBrezina
Thank you!!! That got me compiled!
But now I've got another problem. I run make install
$ sudo make install
Executing sudo -- bash -x -v -c "make" 'install'
[sudo] password for klfjoat:
"make" 'install'
+ make install
make -C build install

But when I run the program, I get...
$ cmmk_ctrl
cmmk_ctrl: error while loading shared libraries: libcmmk.so: cannot open shared object file: No such file or directory
$ which cmmk_ctrl
/usr/local/bin/cmmk_ctrl
I've verified that it installed to /usr/local/bin/cmmk_ctrl and the library is in /usr/local/lib/libcmmk.so.
I have also verified that /usr/local/lib is declared in /etc/ld.so.conf.d/*
And I have run sudo ldconfig.
Any further assistance you can provide would be great!
@KlfJoat to be honest I forced it. Tried manually installing to ~/.local (basically copying contents of dist) but that got me the same message. Then copied it to / .. So basically you probably need to copy libcmmk.so to /liband you current installation should run
