Issue with building modified Clang with llvm

[yashie2011]

I have been trying to install accept compiler on a ubuntu 16.04 machine. I run the command "make setup" after installing Cmake, Ninja and virtual-env. I get the following error which I am not sure how to debug.

cd llvm/tools ; ln -s ../../clang .
ln: failed to create symbolic link './clang': Operation not supported
Makefile:103: recipe for target 'llvm/tools/clang' failed

Thank you.

That's interesting! Is there anything strange about the filesystem you're running this on? Some quick googling suggests that this might happen on a hypervisor's shared volumes, for example: https://communities.vmware.com/thread/312591

[yashie2011]

Yes. The compiler source code was located in a shared/network volume, and the root file system is in local drive. Installation was successful on a standalone drive.

But I might be running out of disk space. It doesn't work If I want to save my installation on a network drive. Not a high priority issue but worth trying for a fix.

Thank you.

OK! I’m not sure what to suggest, though, if your FS doesn’t support symlinks (as most do). Maybe there’s a way to configure your hypervisor to allow symlinks?

If you have another idea for a workaround, a PR would be welcome!

[yashie2011]

Maybe. I will look into that. Thank you
