Re: [rvm-research] Researching the Jikes RVM

Hi Rajika,
Thanks. I was actually trying that, by trying to add -fPIC to CFLAGS
and CXXFLAGS.
Something like,
CFLAGS="-fPIC"
CXXFLAGS="${CFLAGS}"
export CFLAGS CXXFLAGS

And also by adding them to the GNUMakefile of
components/gcspy/1_012/gcspy1_012/src/src c and cpp, as below.

ifeq ($(UNAME), Linux)
	EXTRA_CC_FLAGS = -D_LINUX_ -fPIC
	EXTRA_LD_FLAGS = -lpthread
	DYNAMIC_FLAG = -shared
        LIB_SUFFIX = so
	CC = g++
endif

However, the error remains. I will look further. But, I feel there
should be some smarter option
that I missed. I mean, building with 'buildit' or 'ant' without going
down to details. Do you think so?

Regards,
Pradeeban.
