sigrok-qt on Linux

This page describes how to build/install sigrok on Linux.

Distribution packages

• Debian / Ubuntu: Uwe Hermann maintains the sigrok packages for Debian unstable (which semi-automatically migrate to Ubuntu after a while).
• Fedora: See Linux/Fedora (work in progress).

Building from source

Requirements

• git
• gcc (>= 4.0)
• g++
• make
• autoconf >= 2.63
• automake >= 1.11
• libtool
• pkg-config >= 0.22
• libglib >= 2.22.0
• libusb >= 1.0.5 (optional, only required for some devices)
• libzip >= 0.8
• zlib >= 1.2.3.1
• libftdi >= 0.16 (optional, only required for some devices)
• libudev >= 151 (optional, only required for some devices)
• Python >= 3.0 (optional, only required for libsigrokdecode)
• GTK+ (optional, only required for building/editing sigrok-gtk)
• Qt + Qt Creator >= 4.5 (optional, only required for building/editing the sigrok-qt)

Installing the build-dependencies

On most Linux distributions there are pre-built packages for the sigrok dependencies (if not, you have to build the packages from source). The installation using a package manager is usually pretty simple.

Debian/Ubuntu:

$ sudo apt-get install git-core gcc g++ make autoconf automake libtool pkg-config \
  libglib2.0-dev libftdi-dev libudev-dev libusb-1.0-0-dev libzip-dev zlib1g-dev python3-dev \
  libgtk2.0-dev qtcreator qt4-designer qt4-dev-tools libqt4-dev

Fedora (TODO: Needs updates):

$ yum install gcc-c++ libtool glib2-devel libftdi-devel libusb1-devel libzip-devel qt-devel python3-devel

Building

First, checkout the sources:

$ git clone git://sigrok.git.sourceforge.net/gitroot/sigrok/sigrok
$ cd sigrok

Building libsigrok:

$ cd libsigrok
$ ./autogen.sh
$ ./configure
$ make
$ sudo make install
$ cd ..

Building libsigrokdecode:

$ cd libsigrokdecode
$ ./autogen.sh
$ ./configure
$ make
$ sudo make install
$ cd ..

Then you need to build the chosen user interfaces (cli, qt or gtk).

For building the command line interface (sigrok-cli):

$ cd sigrok-cli
$ ./autogen.sh
$ ./configure
$ make
$ sudo make install
$ cd ..

For building sigrok-gtk (Note: The GTK+ GUI is not yet usable!):

$ cd sigrok-gtk
$ ./autogen.sh
$ ./configure
$ make
$ sudo make install
$ cd ..

For building sigrok-qt (Note: The Qt GUI is not yet usable!):

$ cd sigrok-qt
$ qmake
$ make
$ sudo make install
$ cd ..

If you get warnings claiming potential symbol conflicts when running qmake, you are likely not invoking qmake-qt4. Try running qmake-qt4 to force the correct version.

Pitfalls

If you get this error:

sigrok-cli: error while loading shared libraries: libsigrok.so.0: cannot open shared object file: No such file or directory

Then you have to rebuild the links to your shared libraries:

$ sudo ldconfig /usr/local/lib

Testing

Scan for devices:

$ sigrok-cli -D
The following devices were found:
ID    Device
0     Zeroplus Logic Cube with 32 probes
demo  Demo device with 8 probes

Get 10 samples from device 0 (Zeroplus Logic Cube in this example):

$ sigrok-cli -d 0 --samples 10
