Odd. I went to try it on godbolt, but for some reason it can't find "llvm/IR/Attributes.inc". In any case I created <a href="https://bugs.llvm.org/show_bug.cgi?id=44060" style="">https://bugs.llvm.org/show_bug.cgi?id=44060</a>. I can try to configure a linux
vm at some point to see if I can repo there - doesn't seem like it should be platform specific :shrug:</div>

Linux here. HowtoUseLLJIT works for me on LLVM 9 built with GCC 9.2, in<br>
release and debug mode.<br>
<br>
But HowToUseJIT fails in both modes as EngineBuilder::create() returns<br>
a nullptr which is not checked for in the example code.<br>
<br>
And LLJITWithObjectCache crashes as well because the symbol lookup<br>
seems to fail, leading to the function pointer being NULL.<br>
<br>
git master has the same issues. Maybe I'm compiling LLVM in the wrong<br>
way. build config is pretty much default:<br>
cmake -DCMAKE_BUILD_TYPE=Release/Debug -DLLVM_BUILD_LLVM_DYLIB=ON ..<br>
<br>
There's an old bug report:<br>
<a href="https://bugs.llvm.org/show_bug.cgi?id=38261">https://bugs.llvm.org/show_bug.cgi?id=38261</a><br>
<br>
The proposed fix for HowToUseJIT does not seem to work anymore.<br>
<br>
Best regards,<br>
Frank<br>
