Pictureflow Error: Wrong Elf class on Ubuntu 8.04 AMD_64

[artcoffeewords]

Is there a way to get the pictureflow working on 64-bit Ubuntu. The error is "wrong ELF class: elfclass32" which I assume is because I am running the 64-bit os. Calibre is working perfectly for me other than the cover flow.

Here is a screenshot of the full error message:

pictureflow is the only thing in calibre that uses C code and it's compiled on a 32-bit system (I dont have a 64 bit system). You can compile it manually if you're up to the challenge.

Thanks for the answer. Compiling it myself is a bit beyond my current knowledge level, but I can learn A challenge is always fun.

just get the source code (instructions are at https://calibre.kovidgoyal.net/wiki/...ctionsforlinux)

In the instructions, change the second line to

cd calibre && make plugins

That will compile the pictureflow plugin placing the output into the directory src/calibre/plugins. Just copy the files there into the calibre installation overwriting the existing ones (do a find or a locate to learn where the files to overwrite are on)

Note that for the compilation to succeed you may need to install the qt-dev and pyqt-dev packages.

I got the source code and I am pretty sure I have the dependent dev packages. When I run the code to make the plugin I get this output with the error code at the end and the /src/calibre/plugins/ folder is empty.

you need python-sip and python-sip-dev as well. Note the line sh: /usr/bin/sip: not found

I had both of those installed already, but I re-installed them. That did the trick. It is working beautifully now. Thanks!
