@lemzwerg say> libpng warning: Application built with libpng-1.2.50 but running with 1.6.34

/usr/include/libpng12/png.h:

Binary incompatibility exists only when applications make direct access
to the info_ptr or png_ptr members through png.h, and the compiled
application is loaded with a different version of the library.

Use options:

pdfsizeopt --use-jbig2=NO

Thank you for reporting this!

This can't be fixed on the pdfsizeopt side, because it's a bug in jbig2. Please report the bug there.

Please follow the Linux installation instructions on http://github.com/pts/pdfsizeopt to avoid this and similar errors.
