No idea how to fix abs arguments in nanopolish
Hi,
to fix bug #853568 I tried a patch (gcc-7.patch) to fix abs() arguments
in nanopolish[1] but I have no idea how to deal with this:
...
g++ -o src/hmm/nanopolish_pore_model_set.o -c -g -O2 -fdebug-prefix-map=/build/nanopolish-0.5.0=. -fstack-protector-strong -Wformat -Werror=format-security -g -O3 -std=c++11 -fopenmp -Wdate-t
src/common/nanopolish_variant.cpp: In function 'std::vector<Variant> extract_variants(const string&, const string&)':
src/common/nanopolish_variant.cpp:32:69: error: call of overloaded 'abs(std::__cxx11::basic_string<char>::size_type)' is ambiguous
size_t difference = std::abs(reference.size() - haplotype.size());

Any idea how to patch this?
Kind regards
