I have a game I'm writing which recently required libjpeg. I wrote some code using libjpeg on some-other-machine and it worked as expected. I pulled the code to this machine and tried compiling and running it and have been getting the runtime error out of libjpeg:

Wrong JPEG library version: library is 62, caller expects 80

If I use ldd to see what the binary is linked to, I get:

ldd Debug/tc | grep jpeg libjpeg.so.62 => /usr/lib/x86_64-linux-gnu/libjpeg.so.62 (0x00007f50f02f2000)

My compile flags include -ljpeg. The current jpeg related shared objects in my /usr/lib looks like this:

The original machine runs Gentoo, 'this' machine runs Ubuntu 11.10. Both are 64-bit. The gentoo box only has libjpeg version 8, it seems.

Ultimately, my question is: How can I resolve this? I'd also like to know how I can determine exactly which library the linker has used.

EDIT: My game also links to SDL_image, which according to ldd, links to libjpeg version 8. I bet this is where my troubles stem from. How can I tell gcc to link my game to libjpeg version 8? I tried -l/usr/lib/libjpeg.so.whatever and it complained about not finding the specified lib.

Please use LD_LIBRARY_PATH. Refer to these useful links as well:

Thanks, these are good reads. See my edit above -- I think I've narrowed down the issue. I don't think setting LD_LIBRARY_PATH is necessary, and your second link provides some compelling reasons not to do so anyway. –  stephelton Nov 30 '11 at 10:03
Intendedly chose to add the second link, emphasising on when not to use the variable. Seems you've figured. –  Nikhil Mulley Nov 30 '11 at 10:06
btw, if you are sure of the library path of libjpeg, would not mind trying with -Wl,-rpath,$(LIB_PATH) option of gcc and see how it goes. –  Nikhil Mulley Nov 30 '11 at 10:08

Following link solved the issue for me. How do you link to a specific version of a shared library in GCC

Excerpt from the link that helped me-

Instead of using "-lcurl" use "-l:libcurl.so.3" And ofcourse also use "-L _installed_path_"

My error was the reverse- "Wrong JPEG library version: library is 80, caller expects 62"

To find out which jpeg library my binary was linked against, I did-

ldd my_binary | grep jpeg

output was-

libjpeg.so.8 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libjpeg.so.8

Clearly, the binary was depending on libjpeg8 (library 80), which was why I was getting the error.

To find out if I really had libjpeg62 in my system, I did

ldconfig -p | grep jpeg

output was-

libplayerjpeg.so.3.0 (libc6,x86-64) => /usr/lib/libplayerjpeg.so.3.0
libopenjpeg.so.2 (libc6,x86-64) => /usr/lib/libopenjpeg.so.2
libjpeg.so.62 (libc6,x86-64) => /usr/local/lib/libjpeg.so.62
libjpeg.so.62 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libjpeg.so.62
libjpeg.so.8 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libjpeg.so.8
libjpeg.so.8 (libc6) => /usr/lib/i386-linux-gnu/libjpeg.so.8
libjpeg.so (libc6,x86-64) => /usr/local/lib/libjpeg.so
libjpeg.so (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libjpeg.so

So in my case, instead of just using -ljpeg, I used this (in the make file)-

-L/usr/lib/x86_64-linux-gnu/ -l:libjpeg.so.62

Don't forget to replace #include (jpeglib.h> in your cpp file with

extern "C" {
#include "jpeglib.h" }

Hope it helps!
