So this generation must happen as a part of the 40 # libjvm compilation. 41 42 # First we need to generate the dtraceGenOffsets tool. When run, this will 43 # produce more header files and a C++ file. 44 45 # Note that generateJvmOffsets.cpp must be compiled as if it were a file 46 # in the libjvm.so, using JVM_CFLAGS as setup in CompileJvm.gmk.
