chicken `echo newobject2.scm | sed 's/_/-/g'` -quiet \
       -dynamic -feature chicken-compile-shared \
       -output-file newobject2_chicken.c
g++ -c -fpic  -O2 -DC_STACK_GROWS_DOWNWARD=1 
-DC_INSTALL_LIB_HOME=/usr/lib/chicken -DC_USE_C_DEFAULTS \
       -I../../../Examples/test-suite/chicken -I../../../Examples/test-suite  
newobject2_wrap.cxx   newobject2_chicken.c
g++ -shared  newobject2_chicken.o   newobject2_wrap.o \
         -lchicken -lstuffed-chicken -lsrfi-chicken -ldl -lm -ldl  -lieee -lm  
-lcrypt -o newobject2.so

or if VARIENT=_csc is used to build, the following

csc -sv `echo newobject2.scm | sed 's/_/-/g'`  newobject2_wrap.cxx  -o 
newobject2.so
/usr/bin/chicken newobject2.scm -output-file newobject2.cpp -dynamic -feature 
chicken-compile-shared -quiet
g++ newobject2_wrap.cxx -o newobject2_wrap.o -g -fPIC -DPIC -DC_SHARED -c 
-DC_NO_PIC_NO_DLL
g++ newobject2.cpp -o newobject2.o -g -fPIC -DPIC -DC_SHARED -c 
-DC_NO_PIC_NO_DLL
rm newobject2.cpp
g++ -o newobject2.so newobject2_wrap.o newobject2.o -lchicken -lsrfi-chicken 
-lstuffed-chicken -fPIC -shared -L/usr/lib -Wl,-R/usr/lib -ldl -lpcre -lm  -ldl 
-lpcre
rm newobject2.o
rm newobject2_wrap.o


both fail with
