This is not a bug in Armadillo, but rather a bug (regression) in GCC 4.7.0 and 4.7.1.
The relevant Armadillo code follows the C++ standard. Code using Armadillo 3.2.3 compiles fine with earlier versions of GCC (4.4, 4.5 and 4.6) as well as CLang 3.0. As such, I suggest filing a bug against the GCC package in Debian. There is a related upstream GCC bug, but there seems to be no progress on it: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53549 On 9 July 2012 20:39, Jet Holloway <jet.hollo...@gmail.com> wrote: > Package: libarmadillo-dev > Version: 1:3.2.3+dfsg-1 > Severity: grave > Tags: upstream > Justification: renders package unusable > > Dear Maintainer, > > I just upgraded libarmadillo-dev and libarmadillo3 from version 3.2.2+dfsg-1 > to 3.2.3+dfsg-1, which caused a program I was working on to fail to compile. > When I removed 3.2.3 and reinstalled 3.2.2 the problem disappeared. > > > The following trivial program also causes the error: > #include <armadillo> > int main() > { > return 0; > } > > > When I try to compile this program with "g++ armadillo_bug.cpp", I get these > errors: > > In file included from /usr/include/armadillo:141:0, > from armadillo_bug.cpp:2: > /usr/include/armadillo_bits/Mat_bones.hpp:545:26: error: no members matching > ‘arma::Mat<eT>::operator=’ in ‘class arma::Mat<eT>’ > /usr/include/armadillo_bits/Mat_bones.hpp:546:27: error: no members matching > ‘arma::Mat<eT>::operator()’ in ‘class arma::Mat<eT>’ > In file included from /usr/include/armadillo:142:0, > from armadillo_bug.cpp:2: > /usr/include/armadillo_bits/Col_bones.hpp:175:27: error: no members matching > ‘arma::Col<eT>::operator()’ in ‘class arma::Col<eT>’ > In file included from /usr/include/armadillo:143:0, > from armadillo_bug.cpp:2: > /usr/include/armadillo_bits/Row_bones.hpp:173:27: error: no members matching > ‘arma::Row<eT>::operator()’ in ‘class arma::Row<eT>’ > > > I am using gcc 4.7.1-2. > I have also downloaded armadillo-3.2.3.tar.gz from the armadillo website and > tried including that header file in the trivial program.
