<div dir="ltr">Do you have Python 2.7 64bit versions available for Solaris (10/11) x86/SPARC, AIX, and HP-UX IA/RISC? I've had the displeasure of having to install 64bit Python on Solaris and AIX and it's an experience I would not recommend even though OpenCSW and Perzl have done much of the legwork already. I'd also just be happy with any pointers to building PyRun or regular Python on such systems if such currently there exist no such builds.</div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, May 13, 2015 at 10:34 AM, Cristiano Cortezia <span dir="ltr"><<a href="mailto:cristiano.cortezia@gmail.com" target="_blank">cristiano.cortezia@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><span class=""><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><span style="font-size:12.8000001907349px">In one of the next releases we'll probably add a tool to bundle</span><br style="font-size:12.8000001907349px"><span style="font-size:12.8000001907349px">complete applications together with pyrun, perhaps even by</span><br style="font-size:12.8000001907349px"><span style="font-size:12.8000001907349px">recompiling it to include the application byte code files</span><br style="font-size:12.8000001907349px"><span style="font-size:12.8000001907349px">right in the binary like we do for the stdlib.</span></blockquote><div><br></div></span><div>Well, that would be simply awesome.

</span>PyRun has the advantage of being able to read the byte code<br>
directly from the binary (using memory mapping). However,<br>
it still needs to run the same startup machinery as Python<br>
itself.<br>
<br>
Note that startup time for Python was a lot worse before<br>
Python used the same approach as PyRun to compile in the<br>
parsed sysconfig data.<br>

<br>
</span>It's certainly possible to use the pyrun build system to create<br>
bundles with more packages and tools included.<br>
<br>
The one we're shipping has most of the stdlib included,<br>
but leaves all the application code to reside on the<br>
sys.path or in a ZIP archive.<br>
<br>
In one of the next releases we'll probably add a tool to bundle<br>
complete applications together with pyrun, perhaps even by<br>
recompiling it to include the application byte code files<br>
right in the binary like we do for the stdlib.<br>
