Hi,
My guess is that you are missing an include.
early in basic_functions.h there is a #include <x10/lang/Complex.h>
Inside of Complex.h, you'll find
#include <complex>
typedef std::complex<double> x10_complex;
So before the struct_equals_inner is defined, we've typedef'ed x10_complex
to std::complex<double> and included <complex>.
My guess is you need to do something similar for the x10_mpz type.

Hi again Dave,
I have moved the files to the according places
x10.runtime/src-cpp/x10/lang and x10.runtime/src-x10/x10
and I can call the constructor and functions in my test program.
But I am really stuck with the integration of the new type.
I am trying to implement the Any interface and making changes according to
the Complex type.
I keep getting large amounts of errors (that seem irrelevant) and the
following error in basic_functions.h:
error: ISO C++ forbids declaration of ‘x10_mpz’ with no type
in three different places.
Firstly in the lines:
inline x10_boolean struct_equals_inner(const x10_mpz x, const x10_mpz y)
{ return x==y; }
inline x10_boolean equals_inner(const x10_mpz x, const x10_mpz y){ return
x==y; }
I checked the other basic types (eg Double) (Complex doesn't declare an
"equals" method) and added this part
@Native("c++", "::x10aux::equals(#this, #x)")
public native def equals(x:Any):Boolean;
@Native("c++", "::x10aux::equals(#this, #x)")
public native def equals(x:Mpz):Boolean;
in my Mpz.x10 file.
I suppose my type should fit in one of the templates in basic_functions.h,
probably this one:
template<class T, class U> inline x10_boolean struct_equals(T x, U y)
{ return struct_equals_inner(x, y); }
but the error persists.
Also, I get the same error in line:
inline x10_int hash_code(const x10_mpz x){return hash_code((x10_ulong)x);}
Now this is a naive implementation until I get the build successful (if
ever)
Any suggestion on these would be of great help!!
last thing..
Is this line required in the .x10 file?
public type Mpz(b:Mpz) = Mpz{self==b};
Most of the types will have it, but Complex doesn't.
Regards,
Konstantina

Hi,
It should work to put the .x10 files in x10.runtime/src-x10/x10/lang and
the .cc/.h files in x10.runtime/src-cpp/x10/lang. You will need to edit
the Makefile in x10.runtime/src-cpp to add the corresponding .o file to
ALL_XRCPP_OBJECTS.
After doing this, you need to force at least enough of the build to
happen so that the new .h files are copied into x10.dist/stdlib/.
Probably the simplest thing to do is in x10.dist, do "ant clean-cpp
dist-cpp"
