Missing libraries with JTAssistant

Bryan Wright's picture

I installed JTassistant from the 32-bit tgz archive here:

Running the enclosed script results in the following error:

error while loading shared libraries: cannot open shared object file: No such file or directory

Sorry for inconvenience - JT Assistant build for Linux has accidental links to unused libraries
(due to different behavior of Windows and Linux linkers, this issue does not affect Windows builds).

To workaround issue you can just create dummy files for missing libraries - e.g. by making symlinks pointing to

ln -s
ln -s
ln -s
ln -s

If you are using newer Linux distributive, you might also need removing file from JT Assistant distribution
(so that it will be used from system without conflicts with libpng library also installed in system).

Note that JT Assistant builds which currently available on download section are relatively outdated.
If you are looking for support of JT files within up-to-date state of TKJT library, it is better contacting Open CASCADE support services.
