Sigil will not launch from the build directory either.
In order to test whether my system is broken, Ive done a clean install of 12.04 in another partition, and installed again using both checkinstall and make install. The result is the same. Sigil will not run. I get the error shown in post 1 when I run the script.
The installation of cmake, Qt5 and Sigil are successful, but Sigil will not launch.
Has anyone successfully installed Sigil onto a 32 bit Ubuntu 12.04 and if so what version of Sigil?
