symbolic link to libturbojpeg.so missing

[Florian Echtler]

On amd64, the missing symlink (libturbojpeg.so -> libturbojpeg.so.0) can lead to the following link error:

    /usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/4.8/../../../x86_64-linux-gnu/libturbojpeg.a(libturbojpeg_la-turbojpeg.o): relocation R_X86_64_32 against `.data' can not be used when making a shared object; recompile with -fPIC
    /usr/lib/gcc/x86_64-linux-gnu/4.8/../../../x86_64-linux-gnu/libturbojpeg.a: error adding symbols: Bad value

Manually adding the missing symlink in /usr/lib/x86_64-linux-gnu/ fixes the issue.

no, you need to install the -dev package.

[Florian Echtler (floe)]

Sorry, I filed the bug against the wrong package, I did indeed mean libjpeg-turbo8-dev.

Installing that package does _not_ fix the issue, as it does not contain any softlink to libturbojpeg.so.

Status changed to 'Confirmed' because the bug affects multiple users.

On my system (Ubuntu 14.04) there is not even a shared object "libturbojpeg.so.0".

Version: libjpeg-turbo8 1.3.0-0ubuntu2

$ dpkg -L libjpeg-turbo8 | grep /usr/lib
/usr/lib
/usr/lib/x86_64-linux-gnu
/usr/lib/x86_64-linux-gnu/libjpeg.so.8.0.2
/usr/lib/x86_64-linux-gnu/libjpeg.so.8

$ dpkg -L libjpeg-turbo8-dev | grep /usr/lib
/usr/lib
/usr/lib/x86_64-linux-gnu
/usr/lib/x86_64-linux-gnu/libjpeg.a
/usr/lib/x86_64-linux-gnu/libturbojpeg.a
/usr/lib/x86_64-linux-gnu/libjpeg.so

[Bart van Strien (bartbes)]

The so file is installed by libturbojpeg, not libjpeg-turbo, which may be why this occurs in the first place. (And libturbojpeg has no dev package.)

Hmm, this doesn't seem to be correct:

$ dpkg -L libturbojpeg
