relocation error: /opt/mozjpeg/jpegtran: symbol jpeg_c_int_param_supported, version LIBJPEG_6.2 not defined in file libjpeg.so.62

Hello,
This is how I built 4.0.2:
$ cd /usr/local/src
$ wget https://github.com/mozilla/mozjpeg/archive/v4.0.2.tar.gz
$ tar -xvzf v4.0.2.tar.gz
$ cd mozjpeg-4.0.2
$ mkdir build
$ cd build
$ cmake .. -DPNG_SUPPORTED=NO
$ make -j8
$ mv /usr/local/src/mozjpeg-4.0.2/build /opt/mozjpeg
Then I run "jpegtran",
$ /opt/mozjpeg/jpegtran -copy none -optimize -outfile out.jpg in.jpg
I get this:
/opt/mozjpeg/jpegtran: relocation error: /opt/mozjpeg/jpegtran: symbol jpeg_c_int_param_supported, version LIBJPEG_6.2 not defined in file libjpeg.so.62 with link time reference
The symlinks seem to be ok...

Any ideas what that error above is about?
Thank you.

🔨 You are not the jpegtran you are trying to use. You should use the one that compiles with libjpeg (included in mozjpeg).
@zvezdochiot Apologies, but what do you mean with:
You are not the jpegtran you are trying to use.
And what is "the one" that compiles with libjpeg, then?
I'm very confused here.
Thank you.
It looks like you've build jpegtran to use libjpeg as a shared library, but installed only jpegtran, but not the shared library that it needs.
Use either jpegtran-static, or install all of MozJPEG's libjpeg system-wide.
Use either jpegtran-static
Thank you @kornelski -- seems that "jpegtran-static" works! Doesn't trigger the error.
