Hi, do you add "D:\Program Files\cgal-4.5\auxiliary\gmp" to your environment
path?

主题: [cgal-discuss] gmp link error

Hi,everyone.

I have encountered a Gmp link problem when I tried to compile a project
with CGAL 4.2, boost 1.56, qt4.8,and VS2010 on Win7 32bit. The error is
listed
below:

cvt.obj : error LNK2019: unresolved external symbol __imp____gmpq_clear
referenced in function "public: __thiscall CGAL::Gmpq_rep::~Gmpq_rep(void)"
(??1Gmpq_rep@CGAL@@QAE@XZ)
1>cvt.obj : error LNK2019: unresolved external symbol 
1>__imp____gmpq_set_d
referenced in function "public: __thiscall CGAL::Gmpq::Gmpq(double)" (??
0Gmpq@CGAL@@QAE@N@Z)
1>cvt.obj : error LNK2019: unresolved external symbol __imp____gmpq_init
referenced in function "public: __thiscall CGAL::Gmpq_rep::Gmpq_rep(void)"
(??
0Gmpq_rep@CGAL@@QAE@XZ)
1>cvt.obj : error LNK2019: unresolved external symbol __imp____gmpq_cmp
referenced in function "public: bool __thiscall CGAL::Gmpq::operator<(class
CGAL::Gmpq const &)const " (??MGmpq@CGAL@@QBE_NABV01@@Z)

It seems the Gmp is not correctly linked . After refer to several similar
discusses, I tried to use two Preprocessor definition, CGAL_NO_AUTOLINK_MPFR
and CGAL_NO_AUTOLINK_GMP, to avoid the lack gmp-vc100-mt-gd.lib error Also,
i tried to add two lib files : libgmp-10.lib and libmpfr-4.lib to the
additional dependencies.
However, it still doesn't work.

Does anyone know how to solve this problem ?
Thank for your time and help.
