</div>Let's make things clear (to me):<br>
Have you pass these steps:<br>
<a href="http://vmkit.llvm.org/use_aot.html" target="_blank">http://vmkit.llvm.org/use_aot.html</a> - Java Ahead of Time (AOT) Compilation ?<br></blockquote><div><br>I followed those instructions - no different result.<br>
</div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
<br>
If yes, how is it finished process of making glibj.zip into native code?<br>
I didn't pass it on my 64-bit machine. Interesting if you get there<br></blockquote><div><br>I'm not sure what you mean. There were no errors in the build, and both llcj and vmcj seem otherwise functional (they both run and print usage information just fine).<br>
