After a little digging it appears not to be a problem with linux per se but glibc 2. (Please correct me if I'm wrong) Fast stdio io in perl uses the hooks _ptr and _cnt specified in the normal stdio.h. Unfortunately _cnt is not visible in the glibc 2 version. I've seen mentions of a glue.c file in glibc source that may allow a work around.

If this is a glibc 2 then there may be future problems on other platforms, or do other platforms that use glibc 2 and have fast perl io, have a modified stdio.h?

Perhaps sfio allows such direct hooks, has anybody else made progress on this issue?

• 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).
