Subject: [Caml-list] Problem building custom toplevel
Hi,

I have a c++-library compiled with the icc-compiler, a c-interface to this 
library (cinterface.h and cinterface.cpp) and stubs files generated using 
camlidl (ocaml_opt.idl, ocaml_opt_stubs.cpp, ocaml_opt.ml, ocaml_opt.mli). 
I try to build a custom toplevel with:

	ocamlmktop -custom -thread unix.cma str.cma bigarray.cma nums.cma \
                                                   threads.cm graphics.cma \
		   ../cinterface/cinterface.o ocaml_opt_stubs.o ocaml_opt.cmo  \
		   /usr/lib/libexpat.a \
		   /usr/lib/libdfftw.a \
                   /opt/intel/compiler60/ia32/lib/libcxa.so \
	            /lib/ld-linux.so \
		   ../lib/libopt.a \
		    -cclib -ldl -cclib -lpthread -cclib -lutil -cclib -lm -cclib -lc \
		   -o ocaml_opt 

but get an almost endless list of undefined references (almost 6000 lines of 
output). Here some examples:
../cinterface/cinterface.o(.text+0x1a): undefined reference to `operator
           new[](unsigned)'
../cinterface/cinterface.o(.text+0xb10): undefined reference to  
         `std::_String_base::_Xran() const'
../cinterface/cinterface.o: In function          
           `std::out_of_range::out_of_range(std::basic_string<char,
            std::char_traits<char>, std::allocator<char> > const&)': 
oe_m2.o(.gnu.linkonce.t._ZNSt6vectorIS_IdSaIdEESaIS1_EE9_Insert_nEPS1_jRKS1_+0x95e):
          undefined reference to `__cxa_end_catch'

oe_m2.o is in libopt.a.

I don't have any idea how to solve this problem. I would be very appreciative 
for help. 

Thanks in advance

Rolf Wester

P.S.: If icc is the problem, compiling libopt.a with g++ would be no option. 
But it should work somehow, I have built a shared library for use with Python 
and that one works.
