Package: ruby-nmatrix Version: 0.1.0~rc3-2 Severity: serious Justification: fails to build from source (but built successfully in the past)
Hi, ruby-nmatrix FTBFS (at least) since GCC 7 was made the default compiler: In file included from math.cpp:125:0: math/idamax.h: In instantiation of 'int nm::math::idamax(size_t, DType*, int) [with DType = nm::Rational<short int>; size_t = long unsigned int]': math/getrf.h:153:44: required from 'int nm::math::getrf_nothrow(int, int, DType*, int, int*) [with bool RowMajor = true; DType = nm::Rational<short int>]' math/getrf.h:211:37: required from 'int nm::math::getrf(CBLAS_ORDER, int, int, DType*, int, int*) [with DType = nm::Rational<short int>]' math/getrf.h:234:22: required from 'int nm::math::clapack_getrf(CBLAS_ORDER, int, int, void*, int, int*) [with DType = nm::Rational<short int>]' math.cpp:1295:3: required from here math/idamax.h:60:15: error: call of overloaded 'abs(nm::Rational<short int>&)' is ambiguous dmax = abs(dx[0]); ~~~^~~~~~~ In file included from /usr/include/c++/7/cstdlib:75:0, from /usr/include/c++/7/bits/stl_algo.h:59, from /usr/include/c++/7/algorithm:62, from math.cpp:116: /usr/include/stdlib.h:735:12: note: candidate: int abs(int) extern int abs (int __x) __THROW __attribute__ ((__const__)) __wur; ^~~ In file included from /usr/include/c++/7/cstdlib:77:0, from /usr/include/c++/7/bits/stl_algo.h:59, from /usr/include/c++/7/algorithm:62, from math.cpp:116: /usr/include/c++/7/bits/std_abs.h:56:3: note: candidate: long int std::abs(long int) abs(long __i) { return __builtin_labs(__i); } ^~~ /usr/include/c++/7/bits/std_abs.h:61:3: note: candidate: long long int std::abs(long long int) abs(long long __x) { return __builtin_llabs (__x); } ^~~ /usr/include/c++/7/bits/std_abs.h:70:3: note: candidate: constexpr double std::abs(double) abs(double __x) ^~~ /usr/include/c++/7/bits/std_abs.h:74:3: note: candidate: constexpr float std::abs(float) abs(float __x) ^~~ /usr/include/c++/7/bits/std_abs.h:78:3: note: candidate: constexpr long double std::abs(long double) abs(long double __x) ^~~ Full log attached.
