This is a strange one: https://koji.fedoraproject.org/koji/buildinfo?buildID=1496787 (cd _build/default/src && /usr/bin/gcc -I /usr/lib64/ocaml -I /usr/lib64/ocaml/bytes -I /usr/lib64/ocaml/cudf -I /usr/lib64/ocaml/extlib -I glpk -O2 -fno-strict-aliasing -fwrapv -fexcess-precision=standard -O2 -g -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -Wp,-D_GLIBCXX_ASSERTIONS -fexceptions -fstack-protector-strong -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -specs=/usr/lib/rpm/redhat/redhat-annobin-cc1 -m64 -mtune=generic -fasynchronous-unwind-tables -fstack-clash-protection -fcf-protection -fPIC -I . -DUSEGLPK -g -o removed_criteria.o -c removed_criteria.cpp) cc1plus: sorry, unimplemented: '-fexcess-precision=standard' for C++ gcc src/notuptodate_criteria.o (exit 1) What I don't understand is where/what adds this flag. It doesn't appear in the upstream project, it's not anywhere in rpm --showrc, and it's not in the dist-git repo. It's not in the build tool this project uses (dune). It's like it's appearing from out of nowhere :-( Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming and virtualization blog: http://rwmj.wordpress.com Fedora Windows cross-compiler.
