Linking error with libjpeg

Question

I am compiling my own library which is linked to libjpeg. I have this compiling on two computers but this does not work on one of them. The error is as follows: Wrong JPEG library version: library is 62, caller expects 80 However ONLY libjpeg8 is installed:

/usr/lib/i386-linux-gnu/libjpeg.so.8
/usr/lib/i386-linux-gnu/libjpeg.so.8.0.2
/usr/lib/x86_64-linux-gnu/libjpeg.a
/usr/lib/x86_64-linux-gnu/libjpeg.so
/usr/lib/x86_64-linux-gnu/libjpeg.so.8
/usr/lib/x86_64-linux-gnu/libjpeg.so.8.0.2
/usr/local/cuda-5.0/jre/lib/amd64/libjpeg.so

And my cmake links to the correct SO file:

-- Found libjpeg:
--  - Includes: /usr/include
--  - Libraries: /usr/lib/x86_64-linux-gnu/libjpeg.so

I honestly have no idea what is going on... Any ideas ? Thanks in advance !

There is something stanger. If I don't link my program to any kind of jpeg libraries, my code compiles, and I can execute it and I also get the same message error. BUT, if I do a ldd on my executable, there is no trace of libjpeg. How is that possible ?

Answer 1

Usefull comment Joe Z ! I remember that I installed a new software on my machine last night "Kingsoft Office" which installed an embedded version of libjpeg (the version 62). But I also uninstalled it last night and I made sure that only the version 8 was still present. But must have messed up my libs. Note that I also have OpenCV installed which was built long time ago with the libjpeg support. So by taking your comment in account, I just rebuilt OpenCV without the libjpeg support and everything works fine now.
