C++ MTL Library dimension.h bug?

Question

I've installed MTL on my Fedora Core 12 x64 system, but when building an application I get the following error:

In file included from /usr/local/include/mtl/matrix.h:41,
                 from /usr/local/include/mtl/mtl.h:40,
                 from ltiSystem.hxx:4,
                 from strTools.hxx:4,
                 from ff.cxx:3:
/usr/local/include/mtl/envelope2D.h:72: error: declaration of ‘typedef struct mtl::twod_tag mtl::envelope2D<T>::dimension’
/usr/local/include/mtl/dimension.h:19: error: changes meaning of ‘dimension’ from ‘class mtl::dimension<typename mtl::dense1D<T, 0>::size_type, 0, 0>’
make[1]: *** [ff.o] Error 1

Which would imply an error in MTL. I have changed to different MTL versions and the problem persists, but on Google there is no proper answer. I use the g++ compiler.

Does anyone have a clye?

Answer 1

the problem is in your code, almost hundred percent guarantee.

Look for ambiguous declaration with dimension, i.e. typedef mtl::envelope2D<T>::dimension dimension

Answer 2

Well, I thought so too, but it also happens with the test-suite that is bundled with MTL.
