<p>Hi,</p>
<p>I try to create an execution engine, but I always got a nullptr
value :</p>
<p> _executionEngine =
EngineBuilder(std::move(_module)).create();</p>
<p>I build my project with cmake and add the following command in my
cmake.</p>
<p> llvm_map_components_to_libnames(llvm_libs Analysis Core
ExecutionEngine InstCombine Object RuntimeDyld ScalarOpts Support
native mcjit)</p>
<p>BTW, I have also try to execute the LLVM example project
"HowToUseJIT", and it also return NULL ! And then crash !</p>
<p>Any idea ?<br>
</p>
