compile warning/error GCC 3.3.4 for ARM

Thu Oct 08, 2009 5:08 pm

Hello,

I'm working with a cross-compiler (running on Ubuntu x86, producing code for a modest ARM9 embedded computer).

The cross-compile is working fine for generic C++ projects.

But -- simple project which includes Eigen won't build.

Here's the code in question:

#include <Eigen/LU>
#include <Eigen/Array>
using namespace Eigen;

#define SIZE (200)

int main()
{
MatrixXf A = MatrixXf::Random(SIZE, SIZE);
VectorXf b = VectorXf::Random(SIZE);
VectorXf x;

A.lu().solve(b, &x);
...
}

And here's the warning/error report:

g++ -c main.cpp -I /home/chris/dev/eigen2
In file included from /home/chris/dev/eigen2/Eigen/Core:94,
from /home/chris/dev/eigen2/Eigen/LU:4,

functions in class `Eigen::ei_no_assignment_operator' are private

Eigen::Matrix<_Scalar, _Rows, _Cols, _Options, _MaxRows, _MaxCols>&

_MaxCols>::_set(const Eigen::MatrixBase<OtherDerived>&)':
/home/chris/dev/eigen2/Eigen/src/Core/Matrix.h:508: error: parse error before `
;' token


The same code builds and runs perfectly under the native gcc shipped with Ubuntu.

Any clues?

Thanks!

Thanks for the report, this should now be fixed in the 2.0 branch (see the main wiki page for instructions how to get it).

Hi, I'm having the exact same error in OSX 10.3 with gcc 3.3
I'm using the Eigen2 2.0.6 revision
I have updated the source but I see no change in it. Did you port the fix in 2.0.6? If not is it possible to do it?

thanks

never mind my previous message, I've moved to using 2.0 as I see it contains various bug fix.
