VMkit Installation Error

Hi ,

I am following README.txt of vmkit llvm project :
https://llvm.org/svn/llvm-project/vmkit/trunk/README.TXT

I am using Linux as my host machine.

Executing this command : make -j12 just after the
./configure --disable-plugin --disable-examples --disable-Werror

It shows error :

Making all in tools make[1]: Entering directory /home/rtiwari1/llvm_new/vmkit/classpath-0.99/tools' /bin/mkdir -p classes asm /bin/mkdir -p ../tools/generated/gnu/classpath/tools/gjdoc/expr java -classpath ../antlr-4.7.1-complete.jar antlr.Tool -o ../tools/generated/gnu/classpath/tools/gjdoc/expr/ \ ./gnu/classpath/tools/gjdoc/expr/java-expression.g Error: Could not find or load main class antlr.Tool make[1]: *** [tools.zip] Error 1 make[1]: Leaving directory /home/rtiwari1/llvm_new/vmkit/classpath-0.99/tools’ make: *** [all-recursive] Error 1

Please help. I am stuck here from many hours. Even though I installed and tested antlr-4.7.1-complete.jar file in my host machine. But error still generating.

Thanks & Regards,
