Charm++ parallel programming system

[Andy Somogyi <somogyie AT umail.iu.edu>]

Hi all, 

trying to get a shared library built with charm++

Built charm++ with --enable-shared

after some serious hackery in the makefile, i.e. manually tracking down the 
linkage dependencies and so forth, I finally got a .so built. 

Now, down to one last problem: 

libconv-core.so: undefined symbol: __executable_start

I'm building on x86_64 Linux, using gcc 4.1, only COPTS I have are -g -fPIC

This actually works on OSX, and get a fully functional shared lib.

I've also tried adding -L/MY_CHARM/charm/lib to the options below so the 
linker would pick up the .a static libs, and this fails with an error of

mylib.so: undefined symbol: skt_connect

which is odd since this symbol is defined in libconv-util.a, with an nm 
result of 0000000000000e51 T skt_connect

my make section essentially looks like:

mylib.so: $(INCDIR) $(DSTDIR) $(OBJS) $(LIBS)
    $(CHARMC) -verbose -ld++-option \
    "$(COPTI)$(CHARMINC) $(COPTI)$(INCDIR) $(COPTI)$(SRCDIR) $(CXXOPTS)" \
    "$(CHARM_MODULES)" -language charm++ \
    $(OBJS) \
    $(PYTHONLIBS) \
    obj/SharedLibModuleInit.o \
    $(HOME)/opt/charm/lib/libmemory-default.o \
    $(HOME)/opt/charm/lib/libthreads-default.o \
    $(HOME)/opt/charm/lib/libldb-neighbor.o \
    -lsupc++ -lstdc++ \
    -lck -lconv-util -lconv-core -lconv-cplus-y \
    -lm -o mylib.so

So, in any case, all I want is a shared lib (has to be a shared lib, it has 
lots of python extension types) that includes code that used charm++. Does 
not really matter if I statically or dynamically link with the charm++ libs.

Any ideas... please?
