Source: roboptim-core Version: 2.0-1 Severity: serious Justification: fails to build from source
Builds of roboptim-core for 32-bit architectures have been failing: In file included from /.../roboptim-core-2.0/tests/visualization-gnuplot-differentiable-function.cc:26:0: /.../roboptim-core-2.0/include/roboptim/core/visualization/gnuplot-differentiable-function.hh: In function 'roboptim::visualization::gnuplot::Command roboptim::visualization::gnuplot::plot_jac(const DifferentiableFunction&, const argument_t&)': /.../roboptim-core-2.0/include/roboptim/core/visualization/gnuplot-differentiable-function.hh:68:52: error: comparison between signed and unsigned integer expressions [-Werror=sign-compare] /.../roboptim-core-2.0/include/roboptim/core/visualization/gnuplot-differentiable-function.hh:69:52: error: comparison between signed and unsigned integer expressions [-Werror=sign-compare] /.../roboptim-core-2.0/include/roboptim/core/visualization/gnuplot-differentiable-function.hh:74:41: error: comparison between signed and unsigned integer expressions [-Werror=sign-compare] cc1plus: all warnings being treated as errors make[3]: *** [tests/CMakeFiles/visualization-gnuplot-differentiable-function.dir/visualization-gnuplot-differentiable-function.cc.o] Error 1 It looks like the offending comparisons are between unsigned int and Eigen::DenseIndex, which defaults to ptrdiff_t. On 64-bit architectures, it doesn't matter that ptrdiff_t is signed, because it's still wide enough to encompass unsigned int's full range; however, 32-bit architectures don't fare so well. As such, I'd recommend changing the relevant variables' types to DenseIndex to ensure consistency with Eigen and avoid trouble anywhere. Could you please take a look yourself?
