You can check with ldd---here's my dynamic version:
mb@aldous ~ $ ldd /usr/bin/perl5.14.2 linux-vdso.so.1 => (0x00007fff5677e000) libperl.so.5.14 => /usr/lib64/libperl.so.5.14 (0x00007f62b38ff +000) libc.so.6 => /lib64/libc.so.6 (0x00007f62b356d000) libdl.so.2 => /lib64/libdl.so.2 (0x00007f62b3369000) libm.so.6 => /lib64/libm.so.6 (0x00007f62b30e5000) libcrypt.so.1 => /lib64/libcrypt.so.1 (0x00007f62b2eae000) libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f62b2c91000) /lib64/ld-linux-x86-64.so.2 (0x00007f62b3c81000)

I've never bothered to look at how to configure static vs. dynamic compilation but given that both versions exist it must be possible.

I wouldn't worry about it too much though, as another nice feature of virtual memory systems works in your favor: paging. What Linux basically does when loading a binary is just to mark it loaded but paged out to its file. Then when something accesses the image in memory it gets automagically loaded, but in chunks of usually 4 KB, the size of an MMU page. So stuff that's never run is also likely never loaded, unless it has other code that has already been run in its vicinity. It's all pretty damn efficient anyway unless it's C++.

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 or How to display code and escape characters are good places to start.
