<p class=MsoNormal>Hi all,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>After creating a new LLVM-based project, I faced an odd
problem. <span style='font-size:10.0pt;font-family:"Courier New"'>ExecutionEngine::create
</span>always retuned null. After some investigation I found out that it was
due to the target architecture not getting registered. I’m using Visual C++
2005 and in the X86TargetMachine.cpp file an extern variable <span
style='font-size:10.0pt;font-family:"Courier New"'>X86TargetMachineModule </span>is
created to ‘ensure’ that the module is linked in. It works for the example
projects, but not for the one I created. When I write a value to <span
style='font-size:10.0pt;font-family:"Courier New"'>X86TargetMachineModule</span>
in another module, all is fine and dandy…<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Although it’s a viable workaround for now I was wondering if
anyone knew a more elegant solution, or has an explanation why <span
style='font-size:10.0pt;font-family:"Courier New"'>X86TargetMachineModule </span>works
for the example projects but not for mine.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
