Intalling libqwt6 on Ubuntu 16.04

Good Day to you,

I have a program to install which needs the library libqwt6. I am installing it using a .deb package. In previous versions of Ubuntu, it seems that this library could be installed with a simple apt-get but for my version, no package correspond to that name.

So I tried to install the library by first installing QT to then be able to install Qwt. After having done that, I have a file libqwt.so on my disk. I added it to the dynamic linker but the system still cannot find it. When I look for libqwt with :

ldconfig -p | grep libqwt

I get

libqwt6 (libc6)

Does anyone have a simple solution to install this library? Would returning to an older version of Ubuntu be the best way?

Solution

  • Ubuntu 16.04 has packages for qwt.

    Qt4 version is named libqwt6abi1 (development headers: libqwt-dev)

    Qt5 version is named libqwt-qt5-6 (development headers: libqwt-qt5-dev)
