I dont have a gcc-4.7 compiler, and I am not sure about where is
this error coming from, but my two cents:
When I have found these problems in vxl, the error
was related to compiling with std-c++11. (in
your compiler, with -std=c++0x)
If you see the definition of VCL_CAN_STATIC_CONST_INIT_FLOAT, you
will found that the definition depends on the compiler, and in
debian, depends on the version of gnu-c++. Note that in c++-03, this
work fine because the object is defined and initialized in the cxx
file (http://www2.research.att.com/~bs/bs_faq2.html#in-class), but
in case of c++11, any static member of
type can have an initialiser in the class definition (if you do not
use the "adress" of the object), then the object could be defined in
the cxx file, while is initialized in the class.
When could you find this error? For example, if you compile a
library with stdc++11 option on, then,
VCL_CAN_STATIC_CONST_INIT_FLOAT will be compiled such that in the
cxx file (translation unit) you have only the definition and not the
initialization. Then, your programs must be compiled with the same
option, in order to include that initialization in the class, to let
the compiler to use directly the value inline.
Is this your source of errors? I don't know, but it could help to
understand what is wrong.

Well, I don't know about easy - I can't even replicate it.
However, looking at the CMakeLists.txt files for several contrib/mul
libraries, I found some unnecessary and potentially confounding
TARGET_LINK_LIBRARIES dependency entries. I have removed these and committed
Matthieu, if you can check this fixes your problem before Lianqing attempts
another RC, then I'm sure he would be grateful.
If you get your hand on a debian/sid system - the major difference
from another linux system will be the use of gcc-4.7 as default
compiler -, you then apply trunk.patch. You can now run 'run.sh'. You
should get to:
I don't have time to set up a debian system (virtual or otherwise) - and
gcc 4.7 is not one of my standard compilers. It isn't my code - I was
just offering a possible fix. Sorry.
