unresolved external symbols

[Mike Loehr]

Andreas;

I'm not sure how much help I can be, but the gmp_free_func is defined to
gmp_default_free, which is in turn exported from within gmp-impl.

1) You can use Steve Miller's Dependency Walker to look at the exported
symbols from the DLL to see if it is infact exported.

2) Check to see that the defines are set properly for your build (It doesn't
look that you have defined them, but then again I'm not using .net).
You'll need to set -D__GMP_LIBGMP_DLL -D__MPFR_LIBGMP_DLL to get the exports
from the gmp, gmp-impl, mpfr headers properly.

HTH

Mike

Subject: unresolved external symbols



Hello,

I followed Bryan Gladman instructions, to build gmp.lib/gmp.dll and mpfr.lib
with VC 7.1.

When I build an application using GMP I get unresolved external symbols.

Did any other user ran into the same problem, and can give me a hint.

thank's in advance,

andreas
