Hello,</div>

I am trying to compile LLVM/Clang(10.0) for iOS Simulator (SDK 13.4) and to do that I have made the following changes to the codebase:</div>
<div style="font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
1) I added the following line to CMakeLists.txt under llvm-project/clang:</div>
<div style="font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -arch x86_64 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk -miphoneos-version-min=13.4")</div>
<div style="font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
2) I set CMAKE_OSX_SYSROOT to: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk.</div>
<div style="font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
<br>
</div>
<div style="font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
Then recompiling the code gives me errors like below:</div>

<div>Could someone explain what those errors mean and how to resolve them?</div>
<div>I did set <span style="caret-color: rgb(0, 0, 0); font-family: Calibri, Helvetica, sans-serif;">DYLD_ROOT_PATH to the location of the Simulator executable but that didn't help.</span></div>
<div><span style="background: var(--white);">Also if there is any guide on how to compile LLVM/Clang for iOS simulator I would greatly appreciate if anyone shared it with me.</span><br>
</div>
<div>Any help is greatly appreciated.</div>
