( [id://3333]=superdoc: print w/replies, xml ) Need Help??
If you're doing this because a Perl module has a dependency on a native library (e.g. XML::LibXML), and you need to load the library from a non-default path (e.g. you have a version of libxml2 not in /lib or /usr/lib) and you want to avoid modifying LD_LIBRARY_PATH in a wrapper script or some kind of pseudo-wrapper like that shown above, there is another alternative. In the .bs file for the module, place a call to dl_load_file passing the absolute name of the native library. I used an environment variable to store my custom library path:
# Need to find libxml2. Cannot set LD_LIBRARY_PATH as it is already # cached by the linker. So we load libxml2 BEFORE loading # XML::LibXML's library. dl_load_file($ENV{FOO_PATH} . '/lib/os/libxml2.so.2');

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
