[Solved] Problem installing calibre

[f.bluedevil]

I'm not trying to be obtuse, really I'm not trying ...really

Here is what I've learned so far:

1. Fetch the read me file.
2. Read the README file.
3. Install all the dependencies
4. Don't assume that because you installed all the dependencies, you installed all the dependencies.
5. PyQt4 = PyQt
6. chm_lib = chmlib
7. What people mean when they talk about "dependency hell". ok, it's not really that bad ...so far

Ok, I searched, then I installed chmlib, now I get:

Code: Select all

File "/usr/src/slapt-src/office/calibre/calibre/src/calibre/ebooks/pdb/ereader/writer.py", line 19, in <module>
    import Image
ImportError: No module named Image
fakeroot -- sh calibre.SlackBuild Failed

I tried searching image / Image which turned out to be useless, of course.

The good news is I think I'm about at the end of the build script. The bad news is I'm stuck again

Yes, that's not that obvious. You're looking for "pil", the python image library.

Ok, that did it, calibre is now up and running!

Last question(s) for gapan.

Obviously, I got stuck several times trying to determine which package was required when reading the build error output.

Is it simply a matter of experience knowing that PyQt4 refers to PyQt. (although I get the 4 was a reference to a version #, now.) Or, that chm_lib was a call to chmlib and Image was a reference to pil? Or, was there something in the build script that I missed, that would have told me what I needed to know?

Is there a good reference to read on the subject of package building, or is (trial and error .... repeat until competent) the only real way to get there?

Thanks for your patience as well as all your help!

I don't think you missed anything. It's mostly a matter of experience and recognizing the error messages you receive.

One other thing that can help in determining required dependencies is to have a poke around at the software website. In the case of calibre, on their download_linux page, if you scroll to the bottom you'll find the dependencies listed in a handy table. Sorry I didn't mention it earlier... slipped my mind.

Yikes! Just went through all this to install calibre. Got up to the "pil" problem by doing search and installs with both slapt-get and slap-src before I got the brilliant idea to search the forum. Kinda reminded me when I first started using Linux with Red Hat 9.0 and discovered what dependency hell is all about.
