Hello,
[adding autoconf list again]

Well, I tried to put the namespace as well, but the test failed.
I suppose you mean that you tried
AC_SEARCH_LIBS([cpputils::flip], [cpputils],,[AC_MSG_ERROR(library cpputils not
found)])
which would result in test code:
char cpputils::flip ();
int
main ()
{
return cpputils::flip ();
;
return 0;
}
which is not what we desired. We would like something like (I'm not
certain of your exact signature):
namespace cpputils {
void flip (double);
}
int
main ()
{
using namespace cpputils;
flip (1.0);
;
return 0;
}
You could achieve this by rather calling AC_LINK_IFELSE as below
LIBS="$LIBS -lcpputils"
AC_MSG_CHECKING([for flip in cpputils])
AC_LINK_IFELSE([AC_LANG_PROGRAM([[
namespace cpputils {
void flip(double);
}
]],
[using namespace cpputils;
flip(1.0);])
],
[AC_MSG_RESULT([yes])],
[AC_MSG_RESULT([no])
AC_MSG_ERROR([library cpputils not found])
]
)
Hope that helps.

Isn't the problem that flip(double) is in namespace cpputils?
