Build Error OpnSense

[burns1230]

Hi, everyone!
I installed FreeBSD 12.2 Release version.
And then;

# pkg install git
# cd /usr
# git clone https://github.com/opnsense/tools
# cd tools
# make update

After;

# make kernel

It's build successfully, but

# make base

ld: error: undefined symbol: clang::Sema::BuildCallToMemberFunction()
