Hello. I hope this question is not out of the scope of this discussion
forum.
It's me again, Deltatrinity (Eric).
Well, I installed Visual C++ and trying to use GMP with it. I'm sort of a
newbie there. I had no problems with Borland C++ but trying to use GMP
under MSVC, I only get unresolved externals.
I have this simple code:
#include "stdafx.h"
#include "gmp.h"
int _tmain(int argc, _TCHAR* argv[]) //_tmain is generated by MSVC
{
mpz_t N;
mpz_init(N);
gmp_printf("%Zd\n",N);
return 0;
}
When not specifying any extra files, I get
Linking...
TestEMM.obj : error LNK2019: unresolved external symbol __imp____gmp_printf
referenced in function _main
TestEMM.obj : error LNK2019: unresolved external symbol __imp____gmpz_init
referenced in function _main
Debug/TestEMM.exe : fatal error LNK1120: 2 unresolved externals
If I include libgmp-3.dll-def in the linker options module definition files,
then I get
Linking...
libgmp-3.dll-def : error LNK2001: unresolved external symbol __gmp_0
libgmp-3.dll-def : error LNK2001: unresolved external symbol
__gmp_allocate_func
[snip]
libgmp-3.dll-def : error LNK2001: unresolved external symbol __gmpz_urandomm
libgmp-3.dll-def : error LNK2001: unresolved external symbol __gmpz_xor
Debug/TestEMM.lib : fatal error LNK1120: 382 unresolved externals
LINK : fatal error LNK1141: failure during build of exports file
And I can't seem to make it work.
Anybody successfully compiled under Visual C++ (by the way, I'm building
Win32 console apps in Visual C++ .NET)
Thenks.
