Vijay,

I thought you already followed Ankit's suggestion of manually configuring the compiler, but now when I read the log output again it seems that hasn't been done successfully. The isysroot argument is wrong here.

 "Log" -> {"\"/Applications/Xcode.app/Contents/Developer/Toolchains/\
XcodeDefault.xctoolchain/usr/bin/clang++\" -isysroot \
\"/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.\
platform/Developer/SDKs/DriverKit19.0.sdk\" -m64 -stdlib=libc++ -fPIC \

SystemModeler 12.0 cannot detect Xcode11 correctly so you need to configure it manually (or upgrade to SystemModeler 12.1) You should follow the instructions on this support page https://support.wolfram.com/48717.

Otto,

I did the insall of xcode through above command and still the verify compiler is failing! Any tips further here?
POSTED BY: Vijay Sharma

Start Xcode as Mike suggests and see if it wants/needs to install any updates or if you ned to accept the license. If that doesn't help you can always try and install the command line tools instead. In a terminal run:

xcode-select --install

In the past when I have had similar issues, I have sometimes been able to fix it by "accepting the xcode license". You can do that either through the UI (by running xcode) or at the command line using:

sudo xcodebuild -license

and following the directions.

I usually have to accept the license with every new release of xcode.

Good luck.

Since you are on macOS, XCode is what you should be using. Visual Studio is only for Windows. You say it fails when running:

SystemModelConfiguration`VerifyCompiler[]

What result are you getting from that command? It should include the logs from the verification, which should tell us more about what isn't working.

Thank you, Ankit! I tried the above command and the reference document procedure. But still, the compiler is not getting configured correctly. I do have Xcode installed.

When I run this: SystemModelConfiguration`VerifyCompiler[] it fails.

Should I switch to VScode?

Hi Vijay,

It looks like a compiler issue.

Can you try to evaluate the following command and see if it fixes your problem:

SystemModel;
opts=SystemModelConfiguration`ListCompilers[]
newopts=Replace[opts[[1]],Verbatim[Rule]["PlatformSDKPath",_]"PlatformSDKPath"->"/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk",{1}]
SystemModelConfiguration`SetConfiguration["Compiler",newopts]
