When you try to start an Adobe Acrobat viewer (i.e., Acrobat Reader or Acrobat Exchange) for UNIX from within Netscape Navigator or from a command line, the system returns one of the following errors:

- HP-UX returns the error "can't open shared library lib/libagm.so."

- Sun Solaris returns the error "ld.so.1: acroread: fatal: libreadcore.so: can't open file; errno=2."

- SunOS returns the error "ld.so: libreadcore.so.3: not found."

Solution

Start Acrobat Reader or Acrobat Exchange from the <ACROHOME>/bin directory (where "ACROHOME" is the installation directory for Acrobat) by typing either of the following commands:

- For Acrobat Exchange, type

<ACROHOME>/bin/acroexch

- For Acrobat Reader, type

<ACROHOME>/bin/acroread

Additional Information

Acrobat viewers are designed so that multiple platform binaries can load onto one server system. The acroread and acroexch files in the <ACROHOME>/bin directory contain scripts that determine which UNIX platform the workstation is running. Once the script determines the platform, it sets the environment variables, then calls the acroread or acroexch executable from the appropriate platform bin directory. Attempting to run an Acrobat viewer directly from the platform bin directory causes errors because the environment variables have not been set correctly.

Adobe Reader 6.0 and Adobe Reader 7.x allow you save a copy of a PDF file to your local hard disk. However, they do not let you save changes you make (such as incremental saves while filling out a form) unless the PDF file is rights-enabled. To save changes in a PDF file that is not rights-enabled, you must use Adobe Acrobat Standard or Professional. For information about purchasing Acrobat 6.0 Standard or Professional, visit the Adobe website at http://store.adobe.com/store/products/department.jhtml?id=deptAcrobatFamily .

You can use Adobe LiveCycle Reader Extensions to create a rights-enabled PDF form that enables Adobe Reader users to comment on, complete, save, distribute, submit, and add digital signatures to the form. When you open a rights-enabled PDF form in Adobe Reader, a dialog box appears outlining the extended capabilities of the PDF file.

To view or download sample rights-enabled PDF forms and to learn more about Adobe LiveCycle Reader Extensions, visit the Adobe website at www.adobe.com/products/server/readerextensions/ . For more information about rights-enabled PDF forms, see document 315823 , "Introduction to Adobe Reader 6.0," or document 330983 , "Introduction to Adobe Reader 7.0."
