RE: C++, dlopen() and undefined __pure_virtual


Okay. My apolgies to you all including HJ.
I did try this immediately after getting HJ's mail,
but what i get is the following:

g++ -shared -soname libxyz.so -o libxyz.so -lc X.o -lc Y.o -lc Z.o -lc A.o
-lc B.o -lc C.o -lpthread -lm -ldl
g++: libxyz.so: No such file or directory
g++: unrecognized option `-soname'
make: *** [libxyz.so] Error 1

regards,
bdutta
