>   I compiled the same file(ublas_gesvd.cc) by useing g++(3.4.2) and boost 1.32 ,but still have error.
I got the following error:

/tmp/ccBHG0Ri.o(.gnu.linkonce.t._ZN5boost7numeric8bindings6lapack6detail5gesvdEcciiPdiS4_S4_iS4_iS4_iS4_Pi+0x48):
In function `boost::numeric::bindings::lapack::detail::gesvd(char, char,
int,
int, double*, int, double*, double*, int, double*, int, double*, int,
double*,
int*)':
: undefined reference to `dgesvd_'
collect2: ld returned 1 exit status

 If I rewrite the line 27 in gesvd.hpp
 #include <boost/static_assert.hpp> ==> #include <boost/assert.hpp>
and compiled again via  VC 7.1 ,then I get the following  error :

ublas_gesvd.obj : error LNK2019: unresolved external symbol _dgesvd
referenced in function "void __cdecl
boost::numeric::bindings::lapack::detail::gesvd(char,char,int,int,double

Debug/n3.exe : fatal error LNK1120: 1 unresolved externals

What can I do to solve this problem ?

Thansk!
