Did you try using Sigil with Wine?
I am a Linux user (LMDE64bits) and also a dedicated Sigil user. A number of Linux users had trouble with the Sigil 0.7 release.
- After some difficulties too, I managed to compile Sigil 0.7.0 (using Diap-Dealer's advice) on my 64 bits computer. I did not find a more convenient way to launch it than using a start-up script. I did not update to 0.7.2. I should for this have downloaded the binary of Qt .0.2 and after that compiled again Sigil 0.7.2 and I thought it was not worth the trouble.
- On the other hand, Sigil 0.7.2 is now installed on my computer using Wine
. It was a no brain install. I can start it like any other program. It's of course a 32 bit program but for a mere EPUB I really can't notice any drop in performance. The most important is that we can do it with a plain and small 25 MB install.
- Then I have a third Sigil, which is the old 0.6 version which is handy enough for many tasks and that I keep I do not know really why.
I think I will follow on using Sigil this way till the day when Qt5 will be distributed as a standard for Debian. It can be several months away. Life has become not too easy for Sigil Linux users.
To conclude with it: my best advice for now would be to use Sigil with Wine.
