Package: ball Version: 1.4.3~beta1-1 Severity: serious Dear maintainer:
This package currently fails to build from source: /build/ball-1.4.3~beta1/source/MOLMEC/MINIMIZATION/steepestDescent.C:214:46: required from here /build/ball-1.4.3~beta1/include/BALL/MATHS/common.h:175:18: error: 'isnan' was not declared in this scope, and no declarations were found by argument-dependent lookup at the point of instantiation [-fpermissive] return (isnan(t) != 0); I don't know how to fix this but I know that lots of packages suffered from this "isnan" problem. If you search for any of them which was already fixed I'm quite confident that a fix could be found easily. Build logs here: https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/ball.html Thanks.
